and Sanaz Cherazaie for Defendant and Respondent, Magic Mountain, LLC.
      Appellant Carlos Ibanez suffered traumatic brain injury, among other
injuries, at the Six Flags Magic Mountain amusement park (Magic Mountain) on
August 30, 2008, when he was hit by a roller coaster (called the “Ninja”) as he was
walking in the area in which the Ninja was operating. Ibanez, through his guardian
ad litem, filed a lawsuit against Six Flags Theme Parks, Inc., Six Flags Operations,
Inc., and Magic Mountain, LLC,1 alleging claims for negligence, premises liability,
strict liability, common carrier liability, and negligence per se. The case was tried
twice. In the first trial, jury deadlocked and the trial court declared a mistrial. In
the second trial, the jury returned a verdict in favor of Magic Mountain, finding it
not negligent. On appeal from the judgment, appellant challenges several
evidentiary rulings of the trial court. Although we conclude that the trial court
erred in certain evidentiary rulings, the errors were not prejudicial, and therefore
we affirm the judgment.


                                  BACKGROUND
Factual Background2
      I.     The Accident
      On August 30, 2008, appellant visited Magic Mountain with some friends
and family members. He was wearing a Los Angeles Dodgers cap he had received
as a gift from an uncle who died shortly after giving it to appellant.
      Appellant rode several roller coasters, including one called the “Jet Stream.”
His cap blew off while riding the Jet Stream. After getting off the ride, appellant


1
       Magic Mountain, LLC, referred to as Magic Mountain, is the remaining defendant
and respondent.
2
      We set forth only the evidence pertinent to the issues raised on appeal.

                                            2
spoke to a park employee about his hat and was told that he needed to wait until
the park closed before anyone could look for it. Appellant knew that he could not
stay until the park closed because his group of friends included children who
needed to leave early.
       William Thurman, director of operations for Magic Mountain, testified that
the park’s policy about lost items was to retrieve the items at the end of the day,
unless the item was medication. The park generally did not shut down rides and
retrieve lost items during the day because the process of shutting down the ride and
reopening it took 30 to 45 minutes.
       Appellant and his then brother-in-law, Ramon Ortiz, went to look for the hat,
which appellant thought was in an area behind a wooden fence. They peered
through the slats of the fence but did not see the hat. A sign on the fence stated,
“Authorized Personnel Only,” which appellant understood to mean there would be
someone behind the fence who could help him retrieve the hat. 3 Appellant noticed
a gap in the fence, which was created by a column supporting the Ninja roller
coaster track. The column had a concrete base that was approximately 36 inches
high, but wider in diameter than the column itself, causing the gap between the
column and the wooden fence.
       After searching unsuccessfully for approximately 15 minutes, appellant and
Ortiz went to eat lunch with members of their group. During lunch, appellant told
his friends about his hat, but they told him to forget about it and not to look for it.
Because of the emotional significance of the hat to him, appellant left the group

3
        Magic Mountain asserts in its brief that appellant testified in his deposition that he
believed this sign meant that only employees were allowed to enter the restricted area.
However, the citation Magic Mountain provides does not support this assertion and in
fact is to its own expert’s testimony, not to appellant’s testimony. Appellant testified at
trial.

                                              3
and went to the park’s guest relations office to speak to someone about the hat. An
employee told him that someone would retrieve the hat and mail it to him, but
appellant did not want to wait. Appellant returned to the Jet Stream ride, where the
attendant again told him he needed to wait until the park closed because it was too
dangerous to try to retrieve it.
      Appellant returned to the gap in the wooden fence he had seen previously,
stepped on the concrete base, and slipped into the area behind the fence. Appellant
hoped to find a park employee to help him find his hat.
      Inside the area bounded by the wooden fence there was a four-and-a-half
foot high chain link fence around the perimeter of the Ninja roller coaster track.
There were no warning signs to keep people out of the area enclosed by the chain
link fence. Appellant walked along the inside of the wooden fence and saw a
green box, approximately 3 feet tall and located 18 inches from the chain link
fence. Appellant stepped on the box and climbed over the chain link fence.
      The Ninja roller coaster went by on its track while appellant was behind the
chain link fence. Appellant realized it was dangerous, but he thought the track was
high enough for the roller coaster not to hit him. Appellant already had ridden the
Ninja several times that day and knew that the Ninja is a suspended roller coaster
that hangs below its track. Appellant was struck in the head by the roller coaster.


      II.    The Fences
      Magic Mountain employees testified that the wooden fence was a cosmetic
fence installed in 2006 to prevent guests from seeing an unsightly area. 4 The four-

4
       Thurman acknowledged, however, that there was no documentation describing the
fence as “cosmetic,” and, in fact, prior to this case, no one at Magic Mountain had ever
described the fence in those terms. At his deposition prior to the first trial, Thurman
acknowledged that he did not know the purpose of the wooden fence.
                                               4
and-a-half foot high chain link fence around the perimeter of the Ninja roller
coaster track, called the perimeter fence, was installed when the Ninja was built in
1988. The area within the perimeter fence is referred to as the “red lock area”
because access gates into the area are locked with red locks.


              A.     Testimony of State Inspector
       Magic Mountain called as a witness Bryan Eckman, a safety engineer with
the state of California Department of Industrial Relations Division of Occupational
Safety and Health (DOSH) amusement ride unit, who was responsible for
inspecting amusement park rides in Southern California at the time of the accident.
Eckman testified that he had been working as a “qualified safety inspector” for
DOSH for 12 years, and that DOSH relied on standards known as ASTM standards
in conducting safety inspections. 5
       Eckman testified that ASTM F1159-02 was adopted by the state in 2002 and
addressed the minimum height requirement for fencing around amusement park
rides.6 According to Eckman, at the time of the accident in August 2008, the




5
       “ASTM” stands for “American Society for Testing Materials.” (See Cal. Code
Regs., tit. 8, § 453.) ASTM standards govern permanent amusement park rides in
California pursuant to regulations promulgated by DOSH. (See id., § 3195.1; Lab. Code,
§ 7923.)
6
        ASTM F1159-02 “establishes information and procedures for the design and
manufacture of amusement rides and devices.” It emphasized that “This standard does
not purport to address all of the safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety and health
practices and determine the applicability of regulatory limitations prior to use.” (Italics
in original.) Section 14 of ASTM F1159-02 set forth standards for fencing for
amusement rides manufactured after January 1, 1993. It provided in pertinent part that
“When fences and gates are designed and manufactured to provide protection to
                                               5
regulation required a fence to be “at least 42 inches above the surface upon which
the spectators or riders stand.” 7
       Eckman further testified that DOSH had inspected every ride at Magic
Mountain three times a year from 2002 until the accident in 2008. Eckman had
trained his staff to measure the ride perimeter fencing to ensure it complied with
ASTM F1159-02 and all the rules and regulations of DOSH. He explained that if
the fence height for the Ninja had been deficient, that would have been indicated in
DOSH’s report, along with an order to abate the problem, and DOSH would not
have allowed Magic Mountain to operate the ride if it presented an imminent
hazard. Eckman had examined DOSH’s file for the Ninja and did not find any
documentation of deficiency in the perimeter fencing around the Ninja. He
concluded that, if the chain link fence was 42 inches tall, it complied with state
rules and regulations.
       Eckman inspected the Ninja ride following appellant’s accident. He noticed
the gap in the wooden fence created by the pillar, but he measured the chain link
fence and found that it exceeded the 42-inch minimum height required by the state.
DOSH did not require Magic Mountain to increase the height of the chain link
fence. Eckman did not recall seeing the box on which appellant stood to climb
over the fence. Over appellant’s objection, Eckman testified that, based on the
picture of the box near the fence, he did not believe the box presented an imminent




spectators and riders, they shall be . . . a height of at least 42 in. above the surface on
which the spectators or riders stand.”
7
       Appellant repeatedly objected to Eckman’s testimony on various grounds,
including that Eckman had not been designated an expert witness and that his testimony
violated the Labor Code, but the court overruled the objections.

                                               6
hazard. He further testified that DOSH did not require Magic Mountain to change
any signage after the accident.


             B.    Testimony of Magic Mountain’s Expert
      Magic Mountain’s expert, Carl Freeman, testified that he worked for the
company that designed the Ninja and was involved in the engineering of the ride
and the perimeter fencing when the roller coaster was first installed. Freeman was
a member of the ASTM committee that writes the standards regulating amusement
parks. He testified that ASTM F1159-02 adopted the 42-inch fencing standard
from building codes that were designed to prevent falls from balconies or
stairways. Freeman inspected the chain link fence surrounding the Ninja before
the ride opened to the public and determined that it satisfied the 42-inch minimum
height requirement.
      At the time of trial, Freeman worked for an amusement park called Lagoon
Park in Utah. He testified that in the past, guests at Lagoon Park had been injured
by roller coasters “because they defeated safety barricades around hazardous
zones.” He explained that some areas behind fences are inviting to guests who
have lost items such as jewelry, caps, or cell phones, because there appears to be
sufficient room between the track and the ground to be safe. Lagoon Park uses 9-
foot tall fences around those roller coasters. Freeman described a ride called the
Bat, which has a 7-foot tall fence because guests are able to see inside the
perimeter fencing and might be tempted to enter to retrieve items. Over
appellant’s objection, Freeman continued to testify about perimeter fencing at




                                          7
Lagoon Park’s other roller coasters.8 He stated that rides called the Colossus, Wild
Mouse, and the Puff had perimeter fences of 5 feet 3 inches, 44 inches, and 48
inches respectively. The Ninja’s fence varied between four-and-a-half feet and
five feet high, exceeding the minimum height standard.


             C.     Testimony of Magic Mountain Employees
      Thomas Edgar, Magic Mountain’s safety manager, testified that ASTM
F1159-02 was the industry standard for amusement park rides. According to
Edgar, the 42-inch height requirement for ride perimeter fences had been the
standard since 1997, and the Ninja’s fence exceeded that requirement. He stated
that, in addition to inspections by DOSH and Magic Mountain’s internal
inspections by its own maintenance team, Magic Mountain hired a third party, the
Lundy Group, to conduct inspections of the rides. In 2007 and 2008, the Lundy
Group inspected every ride, including the fences. The Lundy Group did not
recommend making any changes to either the wooden fence or the chain link fence
surrounding the Ninja.
      Edgar further testified that he met regularly with state inspectors. State
inspectors inspected the rides’ fences three times a year from 2003 through 2008
and never required Magic Mountain to increase the height of the chain link fence
or make any other changes. State safety inspectors, including Eckman,
investigated the Ninja after appellant’s accident and did not require Magic
Mountain to make any changes to its fencing



8
       Appellant repeatedly objected that the court previously had excluded his evidence
about fencing at other Magic Mountain roller coasters and so should exclude evidence
about roller coasters’ fences at Lagoon Park, but the court overruled his objections.

                                           8
      Tim Burkhart, the vice president of maintenance and construction for Magic
Mountain, testified that the four-and-a-half-foot chain link fence around the Ninja
was erected in 1988 when the ride was built. The wooden fence was erected in
2006 and was never intended as a perimeter to keep guests out of the restricted
area. Burkhart testified that he had never heard of any park guests entering the
area behind the chain link fence.
      Burkhart testified that the state required the fence to be 42 inches high.
After the accident, Burkhart took Eckman to the fence and showed him that the
fence exceeded the 42-inch height requirement. Burkhart testified that Eckman did
not require Magic Mountain to increase the height of the chain link fence or make
any other changes before the Ninja was reopened.


Procedural Background
      Appellant alleged causes of action for negligence, premises liability, strict
liability, common carrier liability, and negligence per se.
      Before the second trial, both sides renewed several motions in limine which
they had made at the first trial The court adopted the same rulings it had made at
the first trial. As relevant to this appeal, we discuss those evidentiary rulings
below.
      The jury in the second trial returned a verdict in favor of Magic Mountain,
finding it not negligent in the first question of the special verdict form. The court
entered judgment in favor of Magic Mountain. The court denied appellant’s
motion for new trial. Appellant timely appealed.

                                   DISCUSSION
      Appellant contends that the trial court prejudicially erred in several
evidentiary rulings. “We review a trial court’s ruling on the admissibility of
evidence for abuse of discretion. [Citation.] The error is reversible if it resulted in
a miscarriage of justice. [Citation.]” (Nevarrez v. San Marino Skilled Nursing &
Wellness Centre, LLC (2013) 221 Cal.App.4th 102, 117 (Nevarrez).) “‘While trial
judges ordinarily enjoy broad discretion with respect to the admission and
exclusion of evidence in ruling on motions in limine [citation], a court’s discretion
is limited by the legal principles applicable to the case.’ [Citation.] ‘Thus, if the
trial court’s in limine ruling was based upon a misinterpretation of applicable law,
an abuse of discretion has been shown.’ [Citation.]” (McIntyre v. The Colonies-
Pacific, LLC (2014) 228 Cal.App.4th 664, 670.)


I.    DOSH Inspector Bryan Eckman
      Appellant objected to the testimony of DOSH inspector Bryan Eckman, and
to evidence that DOSH had never cited Magic Mountain, on the ground the
evidence was barred by Labor Code section 6304.5 (section 6304.5). The trial
court overruled the objection. On appeal, appellant renews his argument that
section 6304.5 precluded this evidence. We agree.
      Section 6304.5 provides in pertinent part: “Neither the issuance of, or
failure to issue, a citation by the division [DOSH] shall have any application to,
nor be considered in, nor be admissible into, evidence in any personal injury or
wrongful death action, except as between an employee and his or her own
employer. Sections 452 and 669 of the Evidence Code shall apply to this division
and to occupational safety and health standards adopted under this division in the
same manner as any other statute, ordinance, or regulation. The testimony of

                                          10
employees of the division shall not be admissible as expert opinion or with respect
to the application of occupational safety and health standards.” 9
       Based on the plain language of the statute, neither Eckman (nor any other
witness) was entitled to give testimony concerning any “failure to issue a citation”
by DOSH. (See Elsner v. Uveges (2004) 34 Cal.4th 915, 935 [section 6304.5
“prevents nonemployer defendants from showing that no citation was issued”]
(Elsner).) Moreover, Eckman, as a DOSH employee, was not entitled to testify as
an expert or “with respect to the application of” DOSH standards. 10 (§ 6304.5.)
Given these prohibitions, none of Eckman’s testimony was admissible.



9
       Section 6304.5 provides in full: “It is the intent of the Legislature that the
provisions of this division, and the occupational safety and health standards and orders
promulgated under this code, are applicable to proceedings against employers for the
exclusive purpose of maintaining and enforcing employee safety.
       “Neither the issuance of, or failure to issue, a citation by the division shall have
any application to, nor be considered in, nor be admissible into, evidence in any personal
injury or wrongful death action, except as between an employee and his or her own
employer. Sections 452 and 669 of the Evidence Code shall apply to this division and to
occupational safety and health standards adopted under this division in the same manner
as any other statute, ordinance, or regulation. The testimony of employees of the division
shall not be admissible as expert opinion or with respect to the application of
occupational safety and health standards. It is the intent of the Legislature that the
amendments to this section enacted in the 1999-2000 Regular Session shall not abrogate
the holding in Brock v. State of California (1978) 81 Cal.App.3d 752.”
10
        Without citation to authority, counsel for Magic Mountain asserted at oral
argument that Eckman was an employee of a different unit from that at issue in section
6304.5. This assertion is belied by the record and the Labor Code. Eckman testified, “I
work for the State of California Department of Industrial Relations Division of
Occupational Safety and Health amusement ride unit.” Section 7902 of the Labor Code
provides: “The division shall promulgate and formulate rules and regulations for
adoption by the Occupational Safety and Health Standards Board for the safe installation,
repair, maintenance, use, operation, and inspection of all amusement rides as the division
finds necessary for the protection of the general public using amusement rides.” Section
6302 defines the terms used in this portion of the Labor Code and provides that
                                             11
      First, although not designated as an expert witness, Eckman improperly
testified as one. He described his expert credentials – “qualified safety inspector”
for DOSH for 12 years. He explained the 42-inch minimum height requirement of
ASTM F1159-02 for fencing around amusement park rides, stated that the
requirement applied in August 2008 when plaintiff’s accident occurred, and opined
that if the chain link fence around the Ninja was 42 inches tall, it complied with
state rules and regulations. Shown a photograph of the box on which plaintiff
stepped to climb over the chain link fence at the Ninja, Eckman testified that he did
not believe the box presented an imminent hazard. These opinions – the
applicability of ATSM F1159-02, compliance with that provision, and the
nonhazardous nature of the box – were matters “beyond common experience”
(Evid. Code, § 801, subd. (a)), and were based not simply on Eckman’s personal
observations, but on his “special knowledge, skill, experience, training, and
education.” (Id., subd. (b)). They constituted expert, not lay, opinion evidence,
and were inadmissible under section 6304.5. (See People v. Fiore (2014) 227
Cal.App.4th 1362, 1384 [“Unlike an expert opinion, a lay opinion must involve a
subject that is ‘“of such common knowledge that men of ordinary education could
reach a conclusion as intelligently as the witness.”’ [Citation.]”].)
      Second, Eckman improperly testified concerning the “failure to issue . . . a
citation” by DOSH to Magic Mountain, and improperly testified “with respect to
the application of occupational safety and health standards” to Magic Mountain.
(§ 6304.5.) Eckman stated that DOSH inspected every ride at Magic Mountain
three times a year from 2002 until the accident in 2008, and he had trained his staff
to measure the ride perimeter fencing to ensure it complied with ASTM F1159-02

“Department” means the Department of Industrial Relations, and “Division” means the
Division of Occupational Safety and Health. (§ 6302, subds. (b) & (d).)

                                          12
and all the rules and regulations of DOSH. He explained that if the fence height
for the Ninja had been deficient, that fact would have been indicated in DOSH’s
report, along with an order to abate the problem, and DOSH would not have
allowed Magic Mountain to operate the ride if it presented an imminent hazard.
He testified that he had examined DOSH’s file for the Ninja and did not find
documentation of any deficiency in the perimeter fencing around the Ninja. He
also testified that DOSH did not require Magic Mountain to increase the height of
the chain link fence.
      Although the word “citation” was never used, this testimony implicitly
amounted to testimony that DOSH did not issue any citations to Magic Mountain
regarding its fencing. DOSH is required to issue a citation if, after inspection or
investigation, it “believes that an employer has violated . . . any standard, rule,
order, or regulation established pursuant to Chapter 6 (commencing with Section
140) of Division 1 of the Labor Code, or any standard, rule, order, or regulation
established pursuant to this part.” (§ 6317; see § 6302, subd. (d) [defining
“Division” as the Division of Occupational Safety and Health].) Obviously,
testimony that DOSH would not have allowed Magic Mountain to operate the ride
if it presented an imminent hazard, that DOSH’s file for the Ninja noted no
deficiency in its fencing, and that DOSH did not require Magic Mountain to
increase the height of the chain link fence, was tantamount to testimony that no
citation was issued. Further, that testimony necessarily constituted testimony
concerning the application of DOSH standards. Therefore, it was inadmissible
under section 6304.5
      In short, Eckman’s testimony should have been excluded in its entirety.




                                           13
II.    Testimony of Thomas Edgar and Tim Burkhart
       Magic Mountain’s safety manager Thomas Edgar testified that in DOSH
inspections from 2003 through 2008, and in the inspection after plaintiff’s accident
by Eckman, DOSH inspectors did not require Magic Mountain to change the
height of the chain link fence around the Ninja. Similarly, Magic Mountain
employee Tim Burkhart testified that after the inspection concerning plaintiff’s
accident, Eckman did not require any change to the fencing.
       Like Eckman’s testimony, this testimony by Edgar and Burkhart constituted
testimony that DOSH issued no citation to Magic Mountain, and violated the
prohibition of section 6304.5 against such evidence. Section 6304.5 “is
evenhanded, as it prevents nonemployer defendants from showing that no citation
was issued but also prevents nonemployee plaintiffs from showing that a citation
was issued. A legislative judgment was made that in third party cases such
evidence, on either side, ought not to play a role in the jury’s deliberations.”
(Elsner, supra, 34 Cal.4th at p. 935.)


III.   Admission of ASTM F1159-02 Regarding the Standard of Care
       Appellant contends that section 6304.5 precluded the admission of any
evidence that the minimum height requirement of ASTM F1159-02 was relevant to
the standard of care. We already have determined that Eckhart’s testimony
concerning compliance with the height requirement was inadmissible because he
was a DOSH employee. But we disagree that section 6304.5 also precluded other
evidence on the point – in particular, testimony by Edgar (Magic Mountain’s safety
manager) and Carl Freeman, Magic Mountain’s designated expert. We conclude
that although the holding of Elsner, supra, is not dispositive, its interpretation of
section 6304.5 leaves no doubt that Magic Mountain was entitled to introduce the

                                          14
testimony of Edgar and Freeman as evidence showing that it complied with ASTM
F1159-02.
      Edgar, Magic Mountain’s safety manager, testified that ASTM F1159-02
was the industry standard for amusement park rides, that the 42-inch height
requirement for ride perimeter fences had been the standard since 1997, and that
the Ninja’s fence exceeded that requirement. Freeman testified that he worked for
the company that designed the Ninja and was involved in the engineering of the
ride and the perimeter fencing when the roller coaster was first installed. He also
was a member of the ASTM committee that writes the standards regulating
amusement parks. He testified that ASTM F1159-02 adopted the 42-inch fencing
standard from building codes that were designed to prevent falls from balconies or
stairways. He inspected the chain link fence surrounding the Ninja before the ride
opened to the public and determined that it satisfied the 42-inch minimum height
requirement.
      As we explain, this testimony did not violate section 6304.5 as that provision
is construed in Elsner. The current version of section 6304.5 (the version
applicable in the instant case) was adopted by 1999 amendments. In Elsner, the
Supreme Court construed these amendments in a case in which a roofer was
injured when a scaffold collapsed and sued the general contractor on the project,
who had hired the roofer’s employer. Applying the 1999 amendments to section
6304.5 retroactively (the roofer was injured in 1998), the trial court overruled the
contractor’s objection that section 6304.5 precluded evidence that the scaffold
violated Cal-OSHA regulations. Although the Supreme Court concluded that the
trial court erred in applying the amendments retroactively, the court nonetheless
considered the question “to what extent . . . the 1999 amendments repealed the ban
on the admission of Cal-OSHA provisions in third party negligence actions.”

                                          15
(Elsner, supra, 34 Cal.4th at p. 924.) The court “conclude[d] that the amendments
restore the common law rule and allow use of Cal-OSHA provisions to establish
standards and duties of care in negligence actions against private third parties.”
(Id. at p. 924.)
       As Elsner explained, until the 1999 amendments, section 6304.5 (enacted in
1971) provided in relevant part that “‘Neither this division nor any part of this
division shall have any application to, nor be considered in, nor be admissible into,
evidence in any personal injury or wrongful death action arising after the operative
date of this section, except as between an employee and his own employer.’
(Stats. 1971, ch. 1751, § 3, p. 3780.) Thereafter, both [the Supreme Court] and the
Courts of Appeal consistently held that section 6304.5 barred the introduction of
Cal-OSHA provisions in actions between employees and third party tortfeasors.
[Citations.]” (Elsner, supra, 34 Cal.4th at p. 926.)
       In 1999, the Legislature amended section 6304.5 to its current version. In
doing so, it eliminated the language prohibiting consideration of Cal-OSHA
regulations in third party negligence actions. (Elsner, supra, 34 Cal.4th at p. 929
[1999 amendment “deleted . . . language that had imposed a ban in clear and
unmistakable terms” on admission of Cal-OSHA provisions in third party cases].)
In place of the ban, the 1999 amendments added the language we have previously
referred to: “Neither the issuance of, or failure to issue, a citation by the division
shall have any application to, nor be considered in, nor be admissible into,
evidence in any personal injury or wrongful death action, except as between an
employee and his or her own employer. Sections 452 and 669 of the Evidence
Code shall apply to this division and to occupational safety and health standards
adopted under this division in the same manner as any other statute, ordinance, or
regulation.” (§ 6304.5, italics added.)

                                           16
      Interpreting the italicized language, Elsner observed: “Evidence Code
section 452 allows judicial notice of state statutes and regulations. [Citation.]
Evidence Code section 669 allows proof of a statutory violation to create a
presumption of negligence in specified circumstances. It codifies the common law
doctrine of negligence per se, pursuant to which statutes and regulations may be
used to establish duties and standards of care in negligence actions. While adding
this language, the amendments to Labor Code section 6304.5 also deleted
language precluding admission of Cal-OSHA provisions in third party actions . . . .
[¶] In combination, the new language and the deletion indicate that henceforth,
Cal-OSHA provisions are to be treated like any other statute or regulation and may
be admitted to establish a standard or duty of care in all negligence and wrongful
death actions, including third party actions.” (Elsner, supra, 34 Cal.4th at pp. 927-
928, fns. omitted.)
      As here relevant, the court’s specific holding was that “[i]n general,
plaintiffs may use Cal-OSHA provisions to show a duty or standard of care to the
same extent as any other regulation or statute, whether the defendant is their
employer or a third party.” 11 (Elsner, supra, 34 Cal.4th at pp. 935-936.) Of
course, in the instant case the issue is a different one: not whether a plaintiff may
use Cal-OSHA regulations to show negligence per se, but rather whether a
defendant can use compliance with those regulations to show that it met the
applicable standard of care. But as Elsner recognized, the 1999 amendments
repealed the categorical ban on consideration of Cal-OSHA regulations in third

11
       The court interpreted another provision of the 1999 amendments not relevant to
this case to exclude Cal-OSHA provisions “when the state is the defendant based on
actions it took or failed to take in its regulatory capacity; in such cases, Cal-OSHA
provisions remain inadmissible to show liability based on breach of the statutory duty to
inspect worksites and enforce safety rules.” (Elsner, supra, 34 Cal.4th at p. 936.)

                                            17
party negligence cases. Further, while the specific holding of Elsner is that a
plaintiff may use Cal-OSHA standards to prove negligence, nothing in Elsner
suggests that section 6304.5 precludes a defendant from introducing evidence of
compliance with such standards. To the contrary, Elsner states that the 1999
“amendments restore the common law rule and allow use of Cal-OSHA provisions
to establish standards and duties of care in negligence actions against private third
parties.” (Id. at p. 924.)
      The common law rule allows a defendant to introduce evidence that it is in
compliance with a relevant statutory duty of care. In general, courts do not “look[]
favorably on the use of statutory compliance as a defense to tort liability.
[Citation.] That is because a statute, ordinance or regulation ordinarily defines a
minimum standard of conduct. [Citation.] A minimum standard of conduct does
not preclude a finding that a reasonable person would have taken additional
precautions under the circumstances. [Citation.] Nevertheless, where the evidence
shows no unusual circumstances statutory compliance may be accepted by the trier
of fact, or by the court as a matter of law, as sufficient. [Citation.]” (Myrick v.
Mastagni (2010) 185 Cal.App.4th 1082, 1087; see also Nevarrez, supra, 221
Cal.App.4th at p. 115 [“‘[L]ike statutes, applicable regulations are a “factor to be
considered by the jury in determining the reasonableness of the conduct in
question.”’ [Citation.]”]; Amos v. Alpha Property Management (1999) 73
Cal.App.4th 895, 901 [the defendants’ compliance with applicable fire, building
and safety codes was relevant to show due care, although it did not necessarily
negate breach of duty].)
      As to premises liability in particular, “‘a defendant property owner’s
compliance with a law or safety regulation, in and of itself, does not establish that
the owner has utilized due care. The owner’s compliance with applicable safety

                                          18
regulations, while relevant to show due care, is not dispositive, if there are other
circumstances requiring a higher degree of care.’ [Citation.]” (Lawrence v. La
Jolla Beach & Tennis Club, Inc. (2014) 231 Cal.App.4th 11, 31 (Lawrence); see
also Howard v. Omni Hotels Management Corp. (2012) 203 Cal.App.4th 403, 432-
433 [“Although evidence that the condition of the property is in compliance with
‘industry’ standards is relevant, that is not the only inquiry necessary for applying
California premises liability standards.”] (Howard).) Thus, under common law
principles, evidence that Magic Mountain complied with DOSH standards was
relevant, though not dispositive, in determining whether Magic Mountain exercised
due care.
      Appellant contends that the legislative history of section 6304.5 indicates
that Cal-OSHA regulations are admissible only to establish the standard of care by
a plaintiff in pursuing a negligence per se claim. Elsner observed that the 1999
amendments to section 6304.5 were part of “an omnibus measure intended to
increase civil and criminal sanctions against those who maintain unsafe working
conditions. . . . The net effect of the proposed reforms was to increase significantly
the sanctions available against those in control of workplace safety, with the goal
of deterring unsafe practices and reducing the number and severity of future
accidents. This overall purpose is consistent with our reading of the plain language
of the amendments as allowing Cal-OSHA provisions in third party suits and
thereby facilitating private suits against workplace tortfeasors. [Citation.]”
(Elsner, supra, 34 Cal.4th at pp. 929-930.) Given the overall purpose of the
omnibus bill of which the amendments to 6304.5 were a part, we disagree that
allowing a defendant to introduce compliance with Cal-OSHA is inconsistent with
the legislative intent. Permitting defendants to introduce compliance with Cal-
OSHA regulations in defense of workplace lawsuits constitutes an incentive to

                                          19
comply with applicable safety regulations. This is consistent “with the goal of
deterring unsafe practices and reducing the number and severity of future
accidents.” (Elsner, supra, 34 Cal.4th at p. 930.)
      Moreover, “‘[u]nder the standard rules of statutory construction, we will not
read into the statute a limitation that is not there. [Citation.]’ [Citations.]” (Suarez
v. Pacific Northstar Mechanical, Inc. (2009) 180 Cal.App.4th 430, 443.) The
Legislature eliminated the absolute ban on use of Cal-OSHA regulations in third
party actions, and added no language prohibiting a defendant from introducing
evidence that it is in compliance with such regulations. Thus, we presume that
common law negligence principles regarding the admission of safety regulations
apply. As a result in the instant case, Magic Mountain was permitted to introduce
evidence that it was in compliance with the fence height regulation of ASTM
F1159-02. Although, as we have held, Eckman should not have been permitted to
testify on the point, section 6304.5 did not preclude Edgar and Freeman’s
testimony that the perimeter fencing of the Ninja complied with ASTMF 1159-02.
      Noting that the Ninja was built in 1988, appellant contends that the
admission of ASTM F1159-02 was erroneous because that regulation was adopted
in 2002 and the heading of its fencing requirement states: “Fencing for
Amusement Rides and Devices Manufactured After January 1, 1993.” However,
on this record, there was no dispute that the 42-inch minimum requirement
contained in the regulation was the applicable minimum industry standard.
According to Edgar’s testimony, the 42-inch minimum height requirement by
ASTM had been the standard for such fences since at least 1997. Moreover,
Freeman testified that when he approved the installation of the Ninja’s fence
(which occurred in 1988), the 42-inch minimum requirement applied.
Significantly, appellant did not present any evidence that this was not the minimum

                                           20
height standard applicable to the perimeter fencing around Ninja. A defendant’s
compliance with industry standards is relevant to show that the defendant met the
applicable standard of care. (See Lawrence, supra, 231 Cal.App.4th at p. 31;
Nevarrez, supra, 221 Cal.App.4th at p. 115.) As such, evidence that the fencing
around the Ninja complied with the 42-inch requirement, which was adopted in
ASTM F1159-02, was relevant as a factor to consider in determining whether
Magic Mountain was negligent.


IV.   Deposition Testimony of Marilyn Hernandez
      Appellant contends that the trial court erred in excluding the deposition
testimony of Marilyn Hernandez.12 He is mistaken.
      At the time of the second trial, Hernandez was in the Navy. In her
deposition, Hernandez testified that after appellant’s accident, Frank Grey, an
employee of Magic Mountain, showed her the gap in the wooden fence created by
the column supporting the Ninja track. Hernandez asked Grey if appellant could
have gone through that gap, and Grey told her that Magic Mountain previously had
ejected guests from the park for going through the gap.
      In the first trial, Grey testified as a witness, and denied telling Hernandez
this. However, Grey was not called as a witness in the second trial.
      Oddly, appellant contends that Hernandez’s testimony was admissible as
impeachment evidence of Grey in the second trial, even though Grey did not
testify. He cites no applicable authority, and there is none.


12
       Appellant also argues that the trial court erroneously excluded testimony of
appellant’s sister, Lizette Sanchez. Although appellant repeatedly raised this contention
below, he did not offer any proof of what her testimony would be. Thus, the record is
insufficient to consider the contention, and we deem it forfeited.

                                            21
       He also contends that the trial court erred in excluding Hernandez’s
deposition testimony because it was not being offered for a hearsay purpose. We
disagree. Appellant sought to introduce Hernandez’s deposition testimony to
demonstrate Magic Mountain’s awareness that other guests had breached the
perimeter fencing around the Ninja. Hernandez’s deposition testimony that Grey
stated that other guests had been ejected from Magic Mountain for entering the
area was being offered to establish that Magic Mountain had previously ejected
guests from the area and therefore was aware that the area was problematic. The
testimony thus was offered for the truth of the matter asserted within the meaning
of the hearsay rule. (Evid. Code, § 1200, subd. (a).)
       Finally, appellant contends that Hernandez’s deposition testimony was
admissible because she was unavailable as a witness under Code of Civil
Procedure section 2025.620.13 However, in the trial court, he made no showing
that he had “exercised reasonable diligence but has been unable to procure the
deponent’s attendance by the court’s process.” (Code Civ. Proc., § 2025.620,
subd. (c)(2)(E).) Rather, appellant’s counsel simply asserted that Hernandez was
unavailable because she was in the military and that they had “tried to get her.”


13
         Code of Civil Procedure section 2025.620 provides in relevant part: “At the trial
or any other hearing in the action, any part or all of a deposition may be used against any
party who was present or represented at the taking of the deposition . . . , so far as
admissible under the rules of evidence applied as though the deponent were then present
and testifying as a witness, in accordance with the following provisions: [¶] . . . [¶] (c)
Any party may use for any purpose the deposition of any person or organization,
including that of any party to the action, if the court finds any of the following: [¶] . . .
[¶] (2) The deponent, without the procurement or wrongdoing of the proponent of the
deposition for the purpose of preventing testimony in open court, is any of the following:
[¶] . . . [¶] (E) Absent from the trial or other hearing and the proponent of the
deposition has exercised reasonable diligence but has been unable to procure the
deponent’s attendance by the court’s process.”

                                             22
Magic Mountain’s counsel objected that there was no showing of appellant’s effort
to have Hernandez testify. We agree.
      The assertion that counsel had “tried to get” Hernandez does not constitute
an adequate showing of due diligence to obtain Hernandez’s attendance by the
court’s process. (See People v. Friend (2009) 47 Cal.4th 1, 68 [“‘The term
“reasonable diligence” or “due diligence” under Evidence Code section 240,
subdivision (a)(5) “‘connotes persevering application, untiring efforts in good
earnest, efforts of a substantial character. [Citations.]’”’ [Citation.]”].) The trial
court accordingly did not abuse its discretion in excluding Hernandez’s deposition
testimony.


V.    Evidence of Breaches at Other Magic Mountain Rides
      Appellant contends that the trial court abused its discretion in excluding
evidence of breaches of perimeter fences at other rides at Magic Mountain.
Appellant proffered the deposition testimony of Grey, who was a senior supervisor
of rides, including the Ninja, at the time of appellant’s accident, and was a
mechanic for Magic Mountain at the time of trial. 14
      Grey was asked during his deposition, “Did you ever experience . . . anyone
breaching the ride perimeter?” He replied that he had experienced it four times at a
ride called the Tatsu. He knew that one of those incidents involved a breach of the
ride perimeter to retrieve keys that had fallen out during the ride. He further stated


14
       Because Grey was an employee of Magic Mountain, appellant sought to use his
deposition testimony under Code of Civil Procedure section 2025.620, subdivision (b),
which allows an adverse party to use for any purpose “the deposition of a party or one
who was an employee of a party at the time the deposition is taken to be used at trial
against the other party, whether or not the deponent is available.” (Haluck v. Ricoh
Electronics, Inc. (2007) 151 Cal.App.4th 994, 1005; § 2025.620, subd. (b).)

                                           23
that he knew of approximately 12 breaches by guests of perimeter fencing at Magic
Mountain, including the four he experienced. However, none of the breaches
occurred at the Ninja. He heard about the breaches on a radio used for
communication by Magic Mountain employees.
      Appellant argued that the evidence was relevant to show that Magic
Mountain had notice of the dangerous conditions related to inadequate fencing,
gaps in the fence, and/or signage. He further argued that it was relevant to show
that Magic Mountain was negligent in determining a safe height for their perimeter
fences and thus to establish the standard of care. The trial court excluded the
evidence, reasoning that the breaches involved different rides and situations.
      Appellant relies, as he did below, on the principle that “[w]hen evidence is
offered to show only that defendant had notice of a dangerous condition, the
requirement of similarity of circumstances is relaxed: ‘“all that is required . . . is
that the previous injury should be such as to attract the defendant’s attention to the
dangerous situation . . . .”’ [Citation.]” (Hasson v. Ford Motor Co. (1982) 32
Cal.3d 388, 404.) Nonetheless, in order to admit evidence of similar incidents,
appellant is required to show substantial similarity. (Colombo v. BRP US Inc.
(2014) 230 Cal.App.4th 1442, 1475.) The determination of substantial similarity
“‘“is primarily the function of the trial judge.”’ [Citation.]” (Ibid.) We will not
disturb the trial court’s determination unless the record shows an abuse of
discretion. (Stephen v. Ford Motor Co. (2005) 134 Cal.App.4th 1363, 1371
(Stephen).)
      Here, there was no showing of substantial similarity between the breaches of
perimeter fencing at the Tatsu and appellant’s accident. In fact, there was no
showing of similarity at all. Appellant did not provide any details about the
circumstances of the perimeter breaches, such as how or where the breaches

                                           24
occurred. Grey’s general statement that he knew of breaches at the Tatsu is not
sufficiently detailed to show that the circumstances of the other breaches were
substantially similar to the circumstances of appellant’s accident. (See Howard,
supra, 203 Cal.App.4th at p. 434 [similarity of other bathtub-slipping accidents not
shown where there was no “detail about the conditions of or in the bathtubs, or the
circumstances or medical conditions of the guests before they fell in the
bathtubs”]; Stephen, supra, 134 Cal.App.4th at p. 1372 [substantial similarity of
tire-failure accidents not shown where plaintiff did not provide police reports or
other details about the age or condition of the tires or circumstances of the
failures].) The trial court accordingly did not abuse its discretion in excluding the
evidence of breaches at other rides at Magic Mountain.


VI.   Evidence of Taller Perimeter Fences at Magic Mountain
      Appellant sought to introduce evidence regarding the height of perimeter
fences around rides at Magic Mountain other than the Ninja. He argued that the
fences surrounding newer rides, such as the Tatsu, were higher than the Ninja’s
because they were built later and Magic Mountain never upgraded the Ninja’s
fence by making it higher.
      In support of his argument, appellant proffered the deposition testimony of
Lorene Saylor, an auditing supervisor for Six Flags. Saylor, who was 5 feet 4
inches tall, testified that the fence surrounding the Tatsu’s red lock area was taller
than her in some places and over 6 feet high in others. Similarly, the perimeter
fences surrounding the Riddler’s Revenge, X2, Batman, Scream, Goliath, Viper,
and Apocalypse were all taller than Saylor, making them almost a foot higher than
the Ninja’s perimeter fence, which was four-and-a-half feet high. The trial court
excluded the evidence.

                                          25
      Magic Mountain argues, as it did in the trial court, that the height of other
fences is irrelevant because the height depends on each ride’s features and layout.
We are not convinced.
      Evidence is relevant if it has “any tendency in reason to prove or disprove
any disputed fact that is of consequence to the determination of the action.” (Evid.
Code, § 210.) The disputed fact is whether the height of the Ninja’s perimeter
fence was sufficient to deter unauthorized entry.
      Tailoring the height of the fence to each ride’s layout makes sense for fences
such as the wooden fence, whose purpose was described by Magic Mountain as
cosmetic, to hide an unsightly area from guest view. In that situation, the height of
the fence might vary depending, for example, on the slope or size of the unsightly
area. However, the purpose of the perimeter fencing is to deter guests from
entering an unauthorized area. The height considered sufficient by Magic
Mountain to deter unauthorized entry at its other roller coasters is relevant to
considering what height would be sufficient to deter entry into the Ninja’s
perimeter. Indeed, we note that Magic Mountain introduced extensive testimony
(over appellant’s continuing objections) from its expert Freeman about the heights
of perimeter fencing at several roller coasters at Lagoon Park in Utah with no
showing that these roller coasters share similarities with the Ninja. In short, the
exclusion of evidence regarding the height of perimeter fencing at other roller
coasters at Magic Mountain was an abuse of discretion.


VII. Evidence Regarding Signage
      Appellant contends that the trial court erred in excluding certain deposition
testimony of Patrick Hoffman, Vice President for Safety, Security, and Risk
Management for Six Flags Entertainment Corporation, concerning a management

                                          26
decision to supplement signage on all roller coasters at all Six Flags parks in
response to a fatal accident in Georgia in June 2008. We find no error.
      Appellant’s accident occurred on August 30, 2008. He testified that there
were no signs warning him not to enter the area inside the chain link fence or of the
danger if he did enter, and that he would not have entered had there been. He
sought to introduce a portion of Hoffman’s deposition testimony to show that at the
time of appellant’s accident, Magic Mountain had notice of the need for signage
warning patrons not to enter the perimeter fencing of the Ninja.
      In the relevant excerpt, Hoffman was asked whether he ordered the
placement of warning signs in the area of the gap in the fencing around the Ninja.
He replied that he “had asked that signs be put at all of our coasters late in 2008.”
He explained that in June 2008 someone was struck and killed by a roller coaster at
a Magic Mountain park in Atlanta, Georgia after jumping over “two very high
fences.” The state of Georgia asked Six Flags to place “additional signage around
the perimeter of that ride. . . . [T]he ride already had a number of signs on it that
said, Danger zone, do not enter, authorized personnel only, those kinds of things.”
Hoffman testified that he and other members of “senior management” decided to
install additional signage around all the rides at that park, and also “that it would
be a good best practice . . . to install those on all of our coasters throughout our
system.”
      The trial court excluded Hoffman’s deposition testimony at the first trial as
evidence of a subsequent remedial measure under Evidence Code section 1151,15
and adopted the ruling without comment for the second trial. Appellant challenges

15
      Evidence Code section 1151 provides: “When, after the occurrence of an event,
remedial or precautionary measures are taken, which, if taken previously, would have
tended to make the event less likely to occur, evidence of such subsequent measures is
inadmissible to prove negligence or culpable conduct in connection with the event.”
                                            27
this ruling, contending that the evidence was not inadmissible under Evidence
Code section 1151 because it did not concern a remedial measure in response to his
accident, but rather in response to a prior, unrelated accident.
      We need not discuss the correctness of excluding the evidence under
Evidence Code section 1151, because it was inadmissible for a more fundamental
reason: it was irrelevant to the instant case. In substance, the proposed testimony
would have established that sometime “late in 2008,” following the June 2008
accident at the Georgia park and the request for additional signage by Georgia
authorities, Hoffman and other senior managers decided to place additional
warning signs around the roller coasters in all of the parks (presumably including
the Ninja). Appellant contends that the decision to supplement the signage at all
the parks was relevant to prove Magic Mountain was on notice of the need for
additional signage at the Ninja when appellant’s accident occurred. But the
making of that decision sometime “late in 2008” does not show that the decision
was made before appellant’s accident in August 2008 (not generally considered a
late month of the year). Hence, the decision does not reasonably tend to show that
Magic Mountain was on notice of the purported need for additional signage at the
Ninja before then. Moreover, that the Georgia accident occurred in June 2008
(before appellant’s accident) and involved a patron who jumped over two high
fences, does not, in itself, suggest that Magic Mountain was on notice that
additional signage was required for safety at the Ninja. There was no evidence
introduced concerning what, if any, similarity the fencing of the Georgia coaster
bore to the fencing around the Ninja. Therefore, regardless of whether the decision
to supplement the signage at the coasters at all Six Flags parks was a subsequent
remedial measure inadmissible under Evidence Code section 1151, the evidence
was properly excluded because it was irrelevant.

                                          28
VIII. Prejudice
      “A miscarriage of justice occurs if, based on the entire record, including the
evidence, it is reasonably probable the jury would have reached a result more
favorable to appellant[] absent the error. [Citation.] ‘“‘[P]robability’ in this
context does not mean more likely than not, but merely a reasonable chance, more
than an abstract possibility.” [Citation.]’ [Citation.]” (Nevarrez, supra, 221
Cal.App.4th at p. 123.) “[E]rrors in civil trials require that we examine ‘each
individual case to determine whether prejudice actually occurred in light of the
entire record.’ [Citations.]” (Cassim v. Allstate Ins. Co. (2004) 33 Cal.4th 780,
801-802.)
      Examining the entire record, we conclude that the evidentiary errors we have
identified were not prejudicial. We have concluded that Eckman’s testimony was
inadmissible in its entirety, and that the testimony of Thomas Edgar and Tim
Burkhart regarding the failure of DOSH to issue any citation in regard to the
perimeter fencing for the Ninja was also inadmissible. But it is not reasonably
probable that absent this evidence, a different result would have been reached.
Under the other, properly admitted evidence, it was undisputed that the chain link
perimeter fence around the Ninja met and exceeded the minimum height
requirement of ATSM F1159-02. Appellant presented no evidence to dispute that
fact. Moreover, Eckman did not purport to have conducted a full investigation and
to have ruled out any negligence on Magic Mountain’s part. Rather, the
significance of Eckman’s testimony and the inadmissible portion of Edgar and
Burkhart’s testimony was simply that the Ninja perimeter fence met the ATSM
F1159-02 standard and Magic Mountain was not cited for violating that standard.
But even without that evidence, there was no question that Magic Mountain was in

                                          29
compliance with the standard. Thus, the inadmissible testimony added little to the
jury’s consideration of the case.
      It is true that Magic Mountain’s counsel relied on Eckman’s testimony
during closing argument, referring to it as the strongest evidence that Magic
Mountain was not negligent. However, in addition to relying on Eckman’s
testimony, Magic Mountain’s counsel also emphasized that Magic Mountain hired
the Lundy group to conduct independent safety inspections and conducted its own
internal safety inspections, all of which indicated that the Ninja’s fence met and
exceeded the minimum height requirement. In context, it is not reasonably
probable that absent Eckman’s testimony and the inadmissible portions of Edgar’s
and Burkhart’s testimony, a different result would have been reached.
      We also have concluded that the trial court erroneously excluded evidence
concerning the height of fences at other Magic Mountain rides. However, it is not
reasonably probable that the introduction of that evidence would have resulted in a
different verdict. The chain link fence around the Ninja was four-and-a-half feet
high. The evidence of other fencing that appellant sought to introduce merely
showed that the fences at some other attractions were about five-and-a-half to six-
feet tall. Nothing at trial suggested that such additional height would have deterred
or prevented appellant from entering the area where he was injured. Indeed,
appellant was told by at least one ride attendant not to try to retrieve the hat
because it was too dangerous. Appellant’s own expert, Dr. Mark Sanders, opined
that appellant was so “obsessed” with retrieving his hat that a warning sign would
not have stopped him. He stood on an approximately 3-foot tall box at the base of
the perimeter fence to climb over. Standing on that box, for even a six-foot-high
fence he would have had to have traverse only an additional three feet of fence. In
short, the evidence of the height of other fences at Magic Mountain was of very

                                           30
limited probative value, in that it did not reasonably suggest that the modestly
lower fencing height at the Ninja was negligent in itself or that it substantially
contributed to appellant’s ability to traverse the fence. (See Merrill v. Navegar,
Inc. (2001) 26 Cal.4th 465, 477 [to prevail on negligence claim, plaintiff must
show that defendant owed a duty of care, it breached that duty, and the breach was
a legal cause of the plaintiff’s injuries].) “To establish causation, a plaintiff must
prove that the defendant’s conduct was a ‘substantial factor’ in bringing about his
or her harm. [Citations.] Stated differently, evidence of causation ‘must rise to the
level of a reasonable probability based upon competent testimony. [Citations.] “A
possible cause only becomes ‘probable’ when, in the absence of other reasonable
causal explanations, it becomes more likely than not that the injury was a result of
its action.” [Citation.] . . . .’ [Citation.]” (Bowman v. Wyatt (2010) 186
Cal.App.4th 286, 312.) “Where there is evidence that the harm could have
occurred even in the absence of the defendant’s [alleged] negligence, ‘proof of
causation cannot be based on mere speculation, conjecture and inferences drawn
from other inferences to reach a conclusion unsupported by any real evidence . . . .’
[Citation.]” (Padilla v. Rodas (2008) 160 Cal.App.4th 742, 752.)
      On this record, we cannot conclude that absent the errors we have identified
(the erroneous admission of Eckman’s testimony and the other testimony regarding
DOSH’s non-issuance of citations to Magic Mountain, and the exclusion of
evidence regarding the height of perimeter fencing at other Magic Mountain roller
coasters), it is reasonably probable that a different result would have been reached.
