DAVID JOHNSON et al.,
        Plaintiffs and Appellants,
                                                         A142485
v.
UNITED STATES STEEL CORPORATION,                         (Alameda County
                                                         Super. Ct. No. RG13669270)
        Defendant and Respondent.


        Plaintiffs David and Laura Johnson filed a products liability action against
suppliers, manufacturers and retailers of various paints, adhesives, lubricants, solvents,
and other products containing benzene. They contend that David’s chronic exposure as an
auto mechanic to benzene-containing products led him to develop acute myeloid
leukemia (AML). Among the defendants is United States Steel Corporation (U.S. Steel),
which supplied a fabricator with a benzene-containing coal residue called “raffinate” that
was once the principal ingredient in the fabrication of Liquid Wrench, a solvent for
loosening rusted bolts and machine parts.
        In somewhat unorthodox proceedings, the trial court granted summary judgment
to U.S. Steel, finding insufficient evidence to support causes of action for negligence and
strict products liability under a design defect theory. The finding rests on the so-called
“component parts doctrine” (or, as in this case, the “bulk supplier defense”), under which
“the manufacturer of a component part is not liable for injuries caused by the finished
product into which the component has been incorporated unless the component itself was
defective and caused harm.” (O’Neil v. Crane Co. (2012) 53 Cal.4th 335, 355.)
Distinguishing cases that have held raw asbestos to be inherently defective and to contain



                                              1
a design defect under the consumer expectations test, the court held that raffinate is not
inherently defective so that U.S. Steel could not be liable under a design defect theory.
       We agree with the trial court that the supplier of a raw material used in the
manufacture of another product can be held liable for a design defect under the consumer
expectations test only if the raw material is itself inherently defective. However,
summary judgment was granted erroneously because the record does not contain
evidence negating the existence of a design defect under this test of the coal raffinate
produced and sold by U.S. Steel.
                                     Statement of Facts1
       Benzene was first discovered and isolated from coal tar in the 1800’s but, today, is
derived mostly from petroleum. (U.S. Dept. of Health & Human Services, Toxicological
Profile for Benzene (2007) <http://www.atsdr.cdc.gov/toxprofiles/tp3.pdf> [as of Sep. 1,
2015], p. 2 (Benzene Profile).)2 It is a colorless liquid with a sweet odor that is widely
used in the United States in the manufacture of lubricants, plastic, rubber, and pesticides.
(Id. at pp. 1-2.) It “ranks in the top 20 in production volume for chemicals produced in
the United States.” (Id. at p. 2.)
       “Benzene is commonly found in the environment,” mostly from industrial
processes. (Benzene Profile, supra, at p. 2.) “Everyone is exposed to a small amount of
benzene every day. . . . The major sources of benzene exposure are tobacco smoke,
automobile service stations, exhaust from motor vehicles, and industrial emissions.
Vapors (or gases) from products that contain benzene, such as glues, paints, furniture
wax, and detergents, can also be a source of exposure.” (Id. at p. 3.) “Individuals
employed in industries that make or use benzene may be exposed to the highest levels of

benzene.” (Id. at p. 4.) Benzene is a carcinogen. (Id. at p. 6.) Long-term exposure can
cause leukemia, AML in particular. (Ibid.)
       U.S. Steel manufactures steel, which is an alloy of iron and carbon. The company
converts coal to coke for use in steel production. A byproduct of the coking process is
light oil, from which U.S. Steel extracts benzene, toluene and xylene. U.S. Steel sells
these chemicals for industrial use. Raffinate is what remains of the light oil and its
constituent chemicals after most of these “more saleable” chemical compounds are
extracted. “Raffinate” is a chemistry term, defined as “a liquid product resulting from
extraction of a liquid with a solvent” or “the less soluble residue that remains after
extraction (as in refining lubricating oil).” (Webster’s 3d New Internat. Dict. (2002)
p. 1874.) U.S. Steel extracts the benzene, toluene and xylene capable of being distilled
from the light oil but some of these chemicals remain in the raffinate.
       From 1960 to 1978, U.S. Steel sold its raffinate to Radiator Specialty Company
(Radiator). Raffinate was less expensive than the refined chemical compounds of
benzene, toluene and xylene. Radiator purchased U.S. Steel’s raffinate in bulk, in 10,000-
and 20,000-gallon railroad tank cars. The total amount of raffinate purchased by Radiator
is unstated but a Radiator executive estimates the amount to be “hundreds of thousands of
pounds.”
       Radiator is a “formulator;” it does not manufacture or refine chemicals itself.
Radiator formulates Liquid Wrench, which it markets as a “penetrating oil” or liquid
solvent for loosening rusted bolts and machine parts. Radiator introduced Liquid Wrench
in 1941. In the period from 1960 to 1978, Radiator sold at least two different
formulations of Liquid Wrench. One formulation of Liquid Wrench contained as its
principal ingredient raffinate that was supplied solely by U.S. Steel. Raffinate comprised
“about 89 or 90 percent” of the raffinate-based Liquid Wrench. Another formulation of
Liquid Wrench contains petroleum distillates. Radiator markets its petroleum-based
product as “deodorized” Liquid Wrench. The raffinate-based formula was withdrawn
from the market in 1978 but the petroleum-based product continues to be sold today.



                                              3
Radiator distributes its Liquid Wrench formulations nationwide and internationally to
hardware stores, auto parts stores, and other retail outlets.
       In 1960, Congress enacted the Federal Hazardous Substances Act (FHSA) to
“ ‘ “provide nationally uniform requirements for adequate cautionary labeling of
packages of hazardous substances which are sold in interstate commerce and are intended
or suitable for household use.” ’ ” (People ex rel. Lundgren v. Cotter & Co. (1997) 53
Cal.App.4th 1373, 1387, italics omitted; see 15 U.S.C.S. § 1261 et seq.) In response to
the new labeling requirements, Radiator hired chemist consultants to test Liquid Wrench
for toxicity. Chemical tests found the raffinate supplied by U.S. Steel to contain various
amounts of benzene, ranging from 1 to 14 percent. Radiator asked U.S. Steel to detail the
chemical composition of raffinate. In 1963, a manager in U.S. Steel’s coal chemical sales
division wrote to Radiator, stating that the company did “not have positive control over
the composition of this material since it is derived from an extraction process.” The U.S.
Steel manager estimated the composition of raffinate to be benzene (5 percent minimum),
toluene and xylene (25 percent minimum) and aliphatics and cycloparaffins (70 percent
maximum). At the time, U.S. Steel knew benzene to be “one of the most toxic industrial
poisons. When inhaled, it acts principally on the nerve tissue and the blood forming
organs,” “especially the bone marrow and blood vessels.”
       Radiator placed warning labels on Liquid Wrench. The label on the petroleum-
based product said “contains Petroleum Distillate” and the label on the raffinate-based
product said “contains benzol,” another term for benzene. Both labels cautioned users to
avoid prolonged breathing of vapors and stated the products were “harmful or fatal if
swallowed.” The raffinate-based Liquid Wrench label contained additional warnings,
including a skull and crossbones symbol and the word “poison.” No Liquid Wrench
product label or advertisement warned that the product was carcinogenic or could cause
cancer.
       David Johnson testified he first used Liquid Wrench around 1968 when, at age 10,
he began helping his stepfather with auto repairs. In 1971, he became a “shop kid” at a
local service station, where he helped disassemble and clean auto engines, among other


                                               4
tasks. He used Liquid Wrench “almost daily” to loosen bolts. He applied the solvent
“liberally” to saturate the bolts and surrounding area. Johnson sometimes applied Liquid
Wrench while working under a car and the solvent ran down his arm into his armpit; it
would “get all over” him. Johnson continued to use Liquid Wrench in subsequent
employment from 1972 through 1979, as a service station attendant and mechanic. While
working at a salvage yard in 1975, he used one or two bottles of Liquid Wrench a day. He
testified, with equivocation, that there was a skull and cross bones symbol on the Liquid
Wrench container he used at a worksite, which identifies it as the raffinate-based
formula.3 Johnson left automotive mechanical work in 1980. In 1994, Johnson returned to
work as a mechanic and continued in that occupation until 2012, when he was diagnosed
with AML.
                                    Procedural History
       In February 2013, Johnson and his wife filed an action against U.S. Steel,
Radiator, and numerous other defendants alleging Johnson’s personal injury from chronic
exposure to benzene-containing products. The operative first amended complaint states
four cause of action: negligence, strict products liability (design defect and failure to
warn), fraudulent concealment, and loss of consortium.
       U.S. Steel filed a motion for summary judgment or, in the alternative, summary
adjudication. U.S. Steel claimed the evidence was insufficient to show Johnson was
exposed to raffinate-formula Liquid Wrench, thus negating the element of causation on
all causes of action and entitling it to summary judgment. Alternatively, U.S. Steel sought
summary adjudication of the negligence and product liability causes of action to the
extent they are based on a failure to warn. U.S. Steel argued it was a bulk supplier of a
raw material and any duty to warn of the material’s health hazards was discharged when
it provided adequate warnings to Radiator. The trial court ultimately held that there was a

  Johnson was uncertain about product packaging. He described using plastic containers
of Liquid Wrench at a time when Liquid Wrench was packaged exclusively in metal
containers. Johnson testified he saw a skull and crossbones symbol on Liquid Wrench
labels but later said he was “not sure.”


                                              5
triable issue of fact as to Johnson’s exposure to raffinate-based Liquid Wrench but that
U.S. Steel satisfied its duty to warn of health hazards when it provided adequate warnings
to Radiator, thus negating the causes of action for fraudulent concealment, negligence,
and strict products liability based on the alleged failure to warn. Johnson does not
challenge this ruling on appeal. For present purposes, therefore, we proceed on the
assumption that U.S. Steel provided adequate warnings of the health hazards of the
raffinate.
       In its trial court reply brief, U.S. Steel argued for the first time that it was entitled
to summary judgment on all causes of action because it is a “bulk supplier” that provided
a raw material that was added to other ingredients, packaged and sold by an intermediary.
The court requested and received supplemental briefing on the issue, but the statements
of undisputed facts were not supplemented and no additional evidence addressed to the
consumer expectations theory of design defect or to the inherent defectiveness of U.S.
Steel’s raffinate was submitted. Johnson argued that U.S. Steel, as a component supplier,
may be liable for the sale of its benzene-containing raffinate because the raffinate was
defective in design when it left U.S. Steel’s factory, before its incorporation in a finished
product. U.S. Steel argued that raffinate and the benzene it contains are not defective, as
they can be safely used with proper handling, unlike asbestos that is “inherently
defective” and has no safe application. The trial court granted summary judgment to U.S.
Steel, holding that in contrast to asbestos, which “is an inherently defective product,”
Johnson “ha[d] not cited any decisional authority for the proposition that benzene is
inherently defective, or that raffinate is inherently defective because it contains benzene.
The potentially hazardous nature of a substance does not equate to an inherent defect.
(See, e.g., Walker v. Stauffer Chemical Corp. (1971) 19 Cal.App.3d 669, 674.)”
       Johnson and his wife timely filed a notice of appeal from the judgment and
subsequent order awarding costs to U.S. Steel. They challenge only the design defect
ruling and, as indicated above, do not contest dismissal of their failure to warn claims.

                                         Discussion
1. Basic principles in the law of products liability
       “ ‘Products liability is the name currently given to the area of the law involving
the liability of those who supply goods or products for the use of others to purchasers,
users, and bystanders for losses of various kinds resulting from so-called defects in those
products.’ ” (Merrill v. Navegar, Inc. (2001) 26 Cal.4th 465, 478, quoting Prosser &
Keeton, Torts (5th ed. 1984) § 95, p. 677.) One may seek recovery in a products liability
case on theories of both negligence and strict liability. (Jiminez v. Sears, Roebuck & Co.
(1971) 4 Cal.3d 379, 387.)
       The doctrine of strict liability for products was adopted to address the realities of
an industrial society, where “handicrafts have been replaced by mass production” and a
consumer may not have the “means or skill to investigate for himself [or herself] the
soundness of a product” (Escola v. Coca Cola Bottling Co. of Fresno (1944) 24 Cal.2d
453, 467 (conc. opn. of Traynor, J.)) nor sufficient knowledge of the manufacturing
process to prove negligence (id. at p. 463). Strict products liability “insure[s] that the
costs of injuries resulting from defective products are borne by the manufacturers that put
such products on the market rather than by the injured persons who are powerless to
protect themselves.” (Greenman v. Yuba Power Products, Inc. (1963) 59 Cal.2d 57, 63.)
       Strict products liability was originally applied to manufacturers of consumer goods
but has been extended to retailers, distributors, suppliers and other entities in the chain of
distribution of a product that causes harm to a person or to property other than the
product itself. (Jimenez v. Superior Court (2002) 29 Cal.4th 473, 476-478; Taylor v.
Elliott Turbomachinery Co. (2009) 171 Cal.App.4th 564, 575-576.) A “product” is
broadly defined to include any “tangible personal property distributed commercially for
use or consumption.” (Rest.3d Torts, Products Liability, § 19, subd. (a).)
       Strict liability is not absolute liability. (Anderson v. Owens-Corning Fiberglas
Corp. (1991) 53 Cal.3d 987, 994.) A manufacturer is not an insurer for all injuries that
may result from the use of its product; it is liable for injuries caused by a product defect.
(Ibid.) As Justice Traynor observed: “A bottling company is liable for the injury caused


                                               7
by a decomposing mouse found in its bottle. It is not liable for whatever harm results to
the consumer’s teeth from the sugar in its beverage. A knife manufacturer is not liable
when the user cuts himself with one of its knives. When the injury is in no way
attributable to a defect there is no basis for strict liability.” (Traynor, The Ways and
Meanings of Defective Products and Strict Liability (1965) 32 Tenn. L.Rev. 363, 367.)
Strict product liability seeks to hold manufacturers (and others in the stream of
commerce) accountable when there is “something wrong” with the product. (Id. at
p. 366.)
       “[T]he term defect as utilized in the strict liability context is neither self-defining
nor susceptible to a single definition applicable in all contexts.” (Barker v. Lull
Engineering Co. (1978) 20 Cal.3d 413, 427.) Three general types of defects have been
discerned: manufacturing defects, warning defects, and design defects. (Anderson v.
Owens-Corning Fiberglas Corp., supra, 53 Cal.3d at p. 995.) A product has a
manufacturing defect if it “differs from the manufacturer’s intended result or from other
ostensibly identical units of the same product line.” (Barker, supra, at p. 429.) A warning
defect occurs when a manufacturer does not adequately warn the consumer of “a
particular risk that was known or knowable in light of the generally recognized and
prevailing scientific and medical knowledge available at the time of manufacture and
distribution.” (Anderson, supra, at p. 1002.) In California, a product is defective in design
if “the product fails to meet ordinary consumer expectations as to safety” or “the design
is not as safe as it should be.” (Barker, supra, at p. 432; accord Soule v. General Motors
Corp. (1994) 8 Cal.4th 548, 566-570.)
       The California Supreme Court has set out two alternative tests for identifying a
design defect: “first, whether the product performed as safely as an ordinary consumer
would expect when used in an intended and reasonably foreseeable manner and, second,
whether on balance the benefits of the challenged design outweigh the risk of danger
inherent in the design.” (Anderson v. Owens-Corning Fiberglas Corp., supra, 53 Cal.3d
at p. 995.) The consumer expectations test, which is “rooted in theories of warranty,
recognizes that implicit in a product’s presence on the market is a representation that it is


                                               8
fit to do safely the job for which it was intended.” (McCabe v. American Honda Motor
Co. (2002) 100 Cal.App.4th 1111, 1120.) “In particular circumstances, a product’s design
may perform so unsafely that the defect is apparent to the common reason, experience,
and understanding of its ordinary consumers.” (Soule v. General Motors Corp., supra,
8 Cal.4th at p. 569.) Where the product is one of “common experience,” encountered
generally in everyday life, the jury can rely on its own expectations of safety in applying
the test. (Campbell v. General Motors Corp. (1982) 32 Cal.3d 112, 126.) Where a
product is in such “specialized use” that the general public is not familiar with its safety
characteristics, a manufacturer may still be liable if “the safe performance of the product
fell below the reasonable, widely shared minimum expectations of those who do use it.”
(Soule, supra, at p. 567, fn. 4, italics omitted.) The consumer expectations test is not
suitable in all cases. It is reserved for those cases where “the circumstances of the
product’s failure permit an inference that the product’s design performed below the
legitimate, commonly accepted minimum safety assumptions of its ordinary consumers.”
(Id. at pp. 568-569.) If the facts do not permit such an inference, the risk-benefit test must
be used. (Id. at p. 568.) 4



4
  The current Restatement of Torts also recognizes three categories of defects but defines
a design defect to include only instances in which the foreseeable risks of harm posed by
the product could have been reduced or avoided by the adoption of a reasonable
alternative design, i.e., the risk-benefit test. (Rest.3d Torts, Products Liability, § 2,
subd. (b).) However, comment e to this section of the Restatement recognizes the
possibility that there may be product liability absent a reasonable alternative design if the
product design is “manifestly unreasonable.” (Id. at p. 21.) Comment g states that
“although consumer expectations do not constitute an independent standard for judging
the defectiveness of product designs, they may substantially influence or even be
ultimately determinative on risk-utility balancing in judging whether the omission of a
proposed alternative design renders the product not reasonably safe.” (Id. at p. 28.) The
previous edition of the Restatement of Torts provided, in a comment, that to be defective,
“[t]he article sold must be dangerous to an extent beyond that which would be
contemplated by the ordinary consumer who purchases it, with the ordinary knowledge
common to the community as to its characteristics.” (Rest. 2d, Torts, Strict Liability,
§ 402A, com. i, p. 352.)


                                              9
       Sellers of all products are responsible for defects that exist in the product when it
leaves the seller’s control and is placed on the market. Thus, the seller of a completed
product is strictly liable for any defect in the completed product, regardless of the
“source” of the defect; “a manufacturer of a completed product cannot escape liability by
tracing the defect to a component part supplied by another.” (Vandermark v. Ford Motor
Co. (1964) 61 Cal.2d 256, 261.) But the seller of a component part is not strictly liable
for any defect in the completed product but only for those defects in the component part it
sold. (Jimenez v. Superior Court, supra, 29 Cal.4th at p. 480.)
2. The component parts doctrine
       “Component parts are products, whether sold or distributed separately or
assembled with other component parts.” (Rest.3d Torts, Products Liability, § 19, com. b,
p. 268; see Jimenez v. Superior Court, supra, 29 Cal.4th at p. 480 [citing definition]).
“Product components include raw materials, bulk products, and other constituent
products sold for integration into other products.” (Rest.3d Torts, Products Liability, § 5,
com. a, p. 130.) Component manufacturers and suppliers, as sellers of “products,” are
subject to products liability. (Jimenez, supra, at p. 479.) “Like manufacturers, suppliers,
and retailers of complete products, component manufacturers and suppliers are ‘an
integral part of the overall producing and marketing enterprise,’ and may in a particular
case ‘be the only member of that enterprise reasonably available to the injured plaintiff,’
and may be in the best position to ensure product safety.” (Ibid.)
       “The component parts doctrine provides that the manufacturer of a component part
is not liable for injuries caused by the finished product into which the component has
been incorporated unless the component itself was defective and caused harm.” (O’Neil v.
Crane Co., supra, 53 Cal.4th at p. 355.) “If the component itself is not defective, it would
be unjust and inefficient to impose liability solely on the ground that the manufacturer of
the integrated product utilizes the component in a manner that renders the integrated
product defective.” (Rest.3d Torts, Products Liability, § 5, com. a, p. 131.) The
component parts doctrine “ ‘rests on “a line of cases holding an entity supplying a
nondefective raw material or a component part is not strictly liable for defects in the final


                                             10
product over which it had no control.” [Citations.] Under the rule of these cases, the
manufacturer of a product component or ingredient is not liable for injuries caused by the
finished product unless it appears that the component itself was “defective” when it left
the manufacturer.’ ” (Tellez-Cordova v. Campbell-Hausfeld/Scott Fetzger Co. (2004) 129
Cal.App.4th 577, 581, italics added.)
       U.S. Steel contends the component parts doctrine absolves it of liability for
injuries caused by its raffinate that was integrated into Liquid Wrench. Under the
component parts doctrine, U.S. Steel bears no responsibility for damages caused by
Liquid Wrench if the raffinate was not itself defective when delivered to Radiator for
incorporation into the finished product. But U.S. Steel is liable if the raffinate was
defective and its defect caused Johnson’s injuries. Many if not most of the cases
questioning the strict liability of component suppliers concern either alleged
manufacturing defects or alleged failures to provide adequate warnings of the risks
attendant to use of the product. Here, as previously mentioned, the only issue is whether,
under the consumer expectations test, the raffinate was defective in design when
delivered to Radiator.
       Application of the consumer expectations standard to identifiable self-contained
components of larger products into which the component is integrated is conceptually not
difficult. In Wiler v. Firestone Tire & Rubber Co. (1979) 95 Cal.App.3d 621, for
example, summary judgment was granted to an automotive tire manufacturer sued for
manufacturing and design defects upon evidence that the cause of a fatal accident was a
valve stem attached to the tire after the tire left the factory. (Id. at pp. 625, 627, 629-630.)
The tire, a component of the automobile, was itself not defective and thus the tire
manufacturer was not liable. (Id. at pp. 629-630.) In Jimenez v. Superior Court, supra, 29
Cal.4th at page 476, on the other hand, the California Supreme Court held a manufacturer
of windows installed in mass-produced homes strictly liable for harm resulting from
manufacturing and design defects in the windows. The court rejected the window
makers’ claim that it should not be subject to strict products liability because it “merely
supplied component parts” that were assembled and installed by others. (Id. at pp. 479-


                                              11
480.) “The issue is not whether the product was sold fully assembled or in parts, but
rather whether the defect that resulted in the alleged damage existed when the windows
left the manufacturers’ control.” (Id. at p. 480.)
       Application of the consumer expectations test to raw materials that become an
indistinguishable part of another product presents a more difficult conceptual problem,
which is at the nub of the present case. Raw materials are often basic building block
materials with multiple uses. They include “products, whether manufactured, such as
sheet metal; processed, such as lumber; or gathered and sold or distributed in raw
condition, such as unwashed gravel and farm produce.” (Rest.3d Torts, Products
Liability, § 19, com. b, p. 268.) How does one determine there is “something wrong”
with these products? (Traynor, The Ways and Meanings of Defective Products and Strict
Liability, supra, 32 Tenn. L.Rev. at p. 366.) According to a comment in the Restatement,
“a basic raw material such as sand, gravel, or kerosene cannot be defectively designed.
Inappropriate decisions regarding the use of such materials are not attributable to the
supplier of raw materials but rather to the fabricator that puts them to improper use.”
(Rest.3d Torts, Products Liability, § 5, com. c, p. 134.) Yet, in Arena v. Owens-Corning
Fiberglas Corp. (1998) 63 Cal.App.4th 1178, 1186, another division of this court pointed
out that a supplier of raw asbestos was using “the terms ‘design defect’ in too literal a
manner when arguing that asbestos cannot be defectively designed. The term ‘design
defect’ as described in Barker v. Lull Engineering Co., supra, 20 Cal.3d 413, 429 relates
more to a legal conclusion that a product has deviated in some manner from what is
reasonably expected, than it does to a description of a specific mechanical shortcoming or
flaw.”5




5
 The court there went on to state, “To the extent that the term ‘design’ merely means a
preconceived plan, even raw asbestos has a design, in that the miner’s subjective plan of
blasting it out of the ground, pounding and separating the fibers, and marketing them for
various uses, constitutes a design.” (Arena v. Owens-Corning Fiberglas Corp., supra, 63

       Under the consumer expectations test, raw asbestos has been found to be defective
in design and suppliers of raw asbestos held strictly liable for the product. (E.g., Garza v.
Asbestos Corp., Ltd. (2008) 161 Cal.App.4th 651, 658-662; Arena v. Owens-Corning
Fiberglas Corp., supra, 63 Cal.App.4th at pp. 1184-1191; Jenkins v. T&N PLC (1996) 45
Cal.App.4th 1224, 1226-1232.) In Jenkins, the court held, “As a matter of law, a bulk
supplier of raw asbestos fiber incorporated into a finished product can be subject to strict
products liability to an individual suffering from a disease caused by exposure to the
supplier’s asbestos.” (45 Cal.App.4th at p. 1231.) The court reached this decision after
quoting from an opinion of the Illinois Supreme Court holding that “[t]he evidence
showed clearly that handling asbestos in any form produces dust. Liability may be
imposed in a products case if the injury results from a condition of the product and the
condition is unreasonably dangerous and existed when the product left the defendant’s
control.” (Id. at p. 1229, italics deleted.) The court found that the evidence presented at
trial established that “raw asbestos fibers do not change after becoming a component part
of pipe insulation” (ibid.) so that the raw asbestos was properly treated as a “product”
subject to strict products liability.
       In Arena, the court found a supplier of raw asbestos subject to strict products
liability under the consumer expectations test of a design defect. (Arena v. Owens
Corning Fiberglas Corp., supra, 63 Cal.App.4th at p. 1181.) The court noted that
“incorporating raw asbestos into an insulation product does not substantially alter” the
asbestos and contrasted asbestos with other raw materials the physical composition of
which is changed by an intermediary in the process of producing another product that is
unsafe. (Id. at p. 1188, citing, among other cases, Walker v. Stauffer Chemical Corp.,
supra, 19 Cal.App.3d at p. 672 [sulfuric acid in drain cleaner] and Artiglio v. General
Electric Co. (1998) 61 Cal.App.4th 830 [silicone in breast implant].) “[I]t is not the
manufacturing process that creates the dangerous propensity of the asbestos, nor does the
manufacturing process change the nature of the asbestos.” (Arena, supra, at p. 1189.)
Unlike the “sand, gravel, or kerosene” that the comment to the Restatement stated
“cannot be defectively designed” (Rest.3d Torts, Products Liability, § 5, com. c, p. 134),


                                             13
the court observed that “asbestos is not a component material that is usually innocuous,
such as sand [or] gravel” (Arena, supra, at p. 1191) and that an injury caused by exposure
to the product in which it is incorporated is not caused by an intermediary’s use of the
material but by “ a defect in the raw asbestos contained in the product” (ibid.).
       In Garza, this court followed Arena in holding that the consumer expectations test
was properly applied to a raw asbestos supplier. (Garza v. Asbestos Corp., Ltd., supra,
161 Cal.App.4th at pp. 658-660.) We noted that “raw asbestos fibers do not change when
they become a component part of another asbestos product,” unlike the sulfuric acid in
Walker that was substantially altered when used to make a drain cleaner. (Garza, p. 660.)
       In Stewart v. Union Carbide Corp. (2010) 190 Cal.App.4th 23, the court affirmed
a judgment imposing liability for personal injuries on the supplier of asbestos used in the
manufacture of joint compound based on several theories, including “design
defect/consumer expectations.” (Id. at p. 27.) The court rejected application of the
“supplier/component parts doctrine,” pointing out that “[a]sbestos suppliers have sought
the protection of that rule, but it has not been afforded to them, because raw asbestos is a
defective product,” citing Jenkins, Garza, and Arena. (Stewart, p. 29.)
       Raw asbestos has been deemed defective under the consumer expectations test
because factually it has been shown to be inherently injurious, whether or not
incorporated into another product, and because, without a change in its composition, it
causes products into which it is incorporated to perform less safely than ordinary
consumers would expect. As stated in Maxton v. Western States Metals (2012) 203
Cal.App.4th 81, 93, “Asbestos itself is dangerous when handled in any form even if it is
unchanged by the manufacturer. Indeed, asbestos is dangerous when it leaves the
supplier’s control.” Although Maxton considered raw asbestos to be “[t]he one notable
exception” to the rule that raw materials generally cannot by themselves be defective
unless they are contaminated (id. at p. 94), there may be other exceptions. In Arnold v.
Dow Chemical Co. (2001) 91 Cal.App.4th 698, for example, the court held that Dow
Chemical Company, the manufacturer of chemicals used by others to produce pesticides
that were defective under the consumer expectations test, could be strictly liable to those


                                             14
injured by exposure to those pesticides (id. at p. 727). In holding both the manufacturer of
the finished product and Dow as the supplier of the chemical component allegedly
causing the harmful effects to be potentially liable, the court noted that a pesticide, like
asbestos insulation, is “within the ordinary experience and understanding of a consumer”
(ibid.) and a consumer may “reasonably believe that pesticides are designed to eliminate
pests within homes occupied by humans, without causing significant harm to the
humans” (id. at p. 717).
       Two features thus distinguish the cases in which component raw materials have
been found to be defective under the consumer expectations test from cases absolving the
seller of the raw material from liability: first, the raw material in question is itself harmful
and, without change in its composition, remains so when incorporated into other products
and, second, the raw material renders the product into which it is incorporated harmful,
contrary to ordinary consumer expectations. Walker v. Stauffer Chemical Corp., supra,
19 Cal.App.3d 669, a case emphasized by U.S. Steel and distinguished in several of the
asbestos cases cited above, highlights these distinctions. In Walker, the physical
composition of the bulk sulfuric acid claimed to be defective was “substantially altered”
in the process of manufacturing the drain cleaning product into which it was
incorporated. (Id. at p. 672.) “The ultimate product Clear-All can in no way be considered
to be one and the same bulk sulfuric acid manufactured by Stauffer and sold to [the
manufacturer of the Clear-All].” (Ibid.) And sulfuric acid, although potentially
dangerous, is “both a useful and desirable product” that can be incorporated into other
products that presumably are not defective under the consumer expectations or any other
test. (Id. at p. 674.) Similarly, in Maxton, metal products that were alleged to be defective
“were substantially changed during the manufacturing process” (Maxton v. Western
States Metals, supra, 203 Cal.App.4th at p. 93) and “can be used in innumerable ways”
that (implicitly) are not harmful (id. at p. 94). The court affirmed pretrial judgments for
the suppliers of the metal products upon concluding the products were not defective when
they left the suppliers’ control and “only became dangerous because of the manufacturing



                                              15
process controlled by [plaintiff’s] employer.” (Id. at p. 93.)6 In both cases, there was thus
no design defect in the raw material.7
       In the present case, the trial court held that the raffinate sold by U.S. Steel to
Radiator was not defective because Johnson “has not cited any decisional authority for
the proposition that benzene is inherently defective, or that raffinate is inherently
defective because it contains benzene.” Initially, it must be emphasized that the product
in question is not benzene but U.S. Steel’s coal-based raffinate.8 The benzene contained

  A recent case, currently under review, disagreed with Maxton and held a foundry
worker sufficiently alleged direct harm from metal and other raw materials to state a
products liability claim against the suppliers. (Ramos v. Brenntag Specialties, Inc. (2014)
224 Cal.App.4th 1239, review granted July 9, 2014, S218176; accord Uriarte v. Scott
Sales Co. (2014) 226 Cal.App.4th 1396, review granted Sept. 17, 2014, S220088 [strict
liability claims stated by sandblaster against sand supplier].) A central issue in these cases
is whether workers exposed to hazardous raw materials in the course of their work
suffered injury caused by a defect in the material or by inadequate safety precautions of
their employer. That issue is not presented in this case, in which Johnson alleges injury
from exposure to a finished product incorporating what he alleges to be a defective raw
material.

  In holding that the supplier of bulk silicone compounds, safe for many applications, had
no duty to warn arising out of the sale of the compound to the manufacturers of breast
implants who substantially altered the compounds in the manufacturing process, the court
in Artiglio v. General Electric Co., supra, 61 Cal.App.4th at page 839 held that the
authorities “establish that component and raw material suppliers are not liable to ultimate
consumers when the goods or material they supply are not inherently dangerous, they sell
goods or materials in bulk to a sophisticated buyer, the material is substantially changed
during the manufacturing process and the supplier has a limited role in developing and
designing the end product.”

  U.S. Steel notes that benzene is “a familiar and important commodity” with widespread
industrial uses (Industrial Union Dept., AFL-CIO v. American Petroleum Inst. (1980) 448
U.S. 607, 615) that has been found, in at least one case, to be nondefective under a risk-
benefit test because its utility outweighs its dangers (Cole v. Ashland Chemical, Inc.
(E.D. La. Dec. 10, 2010, No. 09-6584) 2010 U.S. Dist. Lexis 131215). Other cases have
found benzene to be “unavoidably unsafe” and defective only if there is a failure to warn
of its hazards. (E.g., Hall v. Ashland Oil Co. (D.C. Conn. 1986) 625 F.Supp. 1515, 1518,
citing Rest.2d Torts, Strict Liability, § 402A, com. k, pp. 353-354.) California has found
a limited number of products to qualify for such treatment—that is, specifically
prescription drugs, vaccines, blood, and medical devices. (Johnson v. Honeywell Internat.
Inc. (2009) 179 Cal.App.4th 549, 562). U.S. Steel does not invoke that doctrine here.

                                              16
in the raffinate may render the raffinate harmful, but it is the raffinate that is claimed to
be defective under the consumer expectations test. Whether that product is defective is a
question of fact, not to be decided by “decisional authority” unless by application of
collateral estoppel. So far as indicated by the authorities brought to our attention, no case
has determined whether the coal-based raffinate produced and sold by U.S. Steel is a
defective product, and the record contains no evidence from which this factual
determination can be made. The record contains no evidence tending to disprove the
toxicity of raffinate or of the products into which it is incorporated in ways that would not
be apparent to most people, no evidence showing that the composition of the raffinate
was altered in the process of formulating Liquid Wrench, and no evidence showing that it
was possible to incorporate the raffinate into Liquid Wrench or any other product without
rendering that product less safe than ordinary consumers would expect. Raffinate may
well be a substance with which ordinary consumers are unfamiliar and have no
expectations concerning its properties or effects. Nonetheless, should the evidence show
that its incorporation into Liquid Wrench, and indeed into any finished product, without
change in its chemical structure causes that product to be less safe than ordinary
consumers would expect, the raffinate will have been shown to contain a design defect
under the consumer expectation test.
       To obtain summary judgment, it was U.S. Steel’s burden to present evidence
negating the existence of a design defect in the raffinate. Having failed to do so, the
burden of presenting contrary evidence never shifted to Johnson. Nonetheless, the record
does contain evidence creating a triable issue of this material fact. “[T]he threshold for
withstanding a motion for summary judgment or nonsuit, thus permitting the jury to
determine whether the allegedly defective product satisfied ordinary consumer
expectations, is quite low.” (Chavez v. Glock, Inc. (2012) 207 Cal.App.4th 1283, 1311.)
There is evidence the raffinate contained between 1 and 14 percent benzene, a known
carcinogen. A U.S. Steel manager estimated its raffinate to contain at least 5 percent
benzene. Johnson says the raffinate lacked “any objective features (a burning sensation
instead of no sensation, or a foul smell instead of a sweet smell) that would alert ordinary


                                              17
consumers that its intended use was extremely dangerous.” Radiator bottled the raffinate
and sold it as Liquid Wrench, apparently with little modification—raffinate comprised
“about 89 or 90 percent” of the raffinate-based Liquid Wrench. U.S. Steel presented no
evidence that Radiator added any chemical or did anything in formulating or packaging
Liquid Wrench that increased the toxicity or danger of the final product from that existing
when the raffinate was delivered to Radiator by U.S. Steel.
       Johnson contends raffinate is a “toxic waste,” without social utility or safe
applications, that should have been sent to a hazardous waste site rather than sold to an
intermediary for consumer use. We express no opinion as to the accuracy of this
assertion. We hold only that U.S. Steel failed to present evidence negating this allegation
and that summary judgment in its favor therefore should not have been granted.
                                        Disposition
       The judgment is reversed. The postjudgment order awarding costs is vacated. The
case is remanded to the trial court with directions to deny the motion for summary
judgment and to conduct further proceedings consistent with this opinion. Plaintiffs shall
recover costs incurred on appeal upon timely application in the trial court.
