MILLS
v.
A.B. DICK COMPANY
Docket No. 7,452.
Michigan Court of Appeals.
Decided August 25, 1970.
*166 Karbel, Eiges, Rothstein & Karbel, for plaintiffs.
Kelly & Tatham, for defendants.
Before: T.M. BURNS, P.J., and LEVIN and DAVIDSON,[*] JJ.
LEVIN, J.
Sidney Mills slipped and fell on a staircase on premises leased by A.B. Dick Company of Detroit, Inc., a wholly-owned subsidiary of A.B. Dick Company, from Continental Assurance Company. He and his wife, Sylvia, commenced this action against the companies named to recover compensation for their damages. At the conclusion of their proofs,[1] the judge directed a verdict for the defendant companies on the grounds that the Mills had neither shown any negligence on the part of the defendants nor that there was a causal relationship between the claimed defect  absence of handrails on the staircase  and Sidney Mills' injuries. We reverse.
Mr. Mills owned and operated a small cartage and delivery business. He had been making deliveries to customers of defendant A.B. Dick Company of Detroit, Inc. for a number of years before the accident and, on the date he was injured, was on the Dick Company premises in connection with that business. He was, thus, on the premises as an invitee.
*167 A possessor of land is not an insurer of an invitee's safety, but he is under an affirmative duty to exercise due care to make the premises reasonably safe for the invitee's use.[2]
The staircase consisted of four or five steps and connected the ground level of an inside garage with a truck loading platform. There is a wall on one side of the staircase, but the other side is open. There is no handrail on either side. While ascending the staircase, Mills lost his footing due to some unknown cause and fell off the open side of the staircase. He hit the concrete pavement below and sustained physical injury.
The defendants correctly assert that a landowner is not liable for an unexplained fall, even to an invitee,[3] but it does not follow from the fact that the surface of the stairs was not shown to have been defective that the Mills cannot recover. If, as they contend, the staircase is defective unless hand-rails *168 are provided, the defendants may yet be subject to liability.
The premises are located in the City of Detroit which, the defendants concede, by ordinance requires the installation of handrails on such a staircase.[4] The violation of an ordinance is not, as distinguished from violation of a statute, negligence per se. It is, however, evidence of negligence.[5] Railings are required for the protection of persons who accidentally lose their balance, including those who lose their balance through no fault of the landowner. The jury should have been permitted to determine whether defendants were negligent in failing to have conformed to the standard of care required by the ordinance.[6]
Moreover, apart from the ordinance, we think the Mills were entitled to have their case submitted to the jury under an instruction that if it finds the installation of a handrail on the open side of the staircase was necessary to make the premises reasonably safe for use by one, who, like Sidney Mills, was invited to come on the premises, on that ground as well it could find that the failure to have provided this safeguard was negligence.[7]
*169 If the jury find that the failure to have provided handrails was negligence, it could also find from the evidence presented that there was a causal relationship between the absence of the railing and Sidney Mills' injuries.[8] He testified that he fell to the right over the unprotected side of the staircase. Had a railing been installed he might well have saved himself from injury.
"Thus where it appears how an accident happened and also that the victim might have saved himself by taking advantage of a precaution which it has been shown defendant negligently failed to afford, courts have generally let a jury find the failure caused the harm, though it is often a pretty speculative matter whether the precaution would in fact have saved the victim." 2 Harper & James, The Law of Torts, § 20.2, p 1113. (Emphasis by authors.)
*170 The Michigan Supreme Court associated itself with this view in Davis v. Buss Machine Works (1913), 175 Mich 61, 73, a case where the defendant failed to provide handrails in accordance with a statutory requirement:
"Neither can we say that the cause of the injury was not the failure to provide a railing. Had there been a railing present plaintiff perhaps might have saved himself from injury even while falling. This was for the jury to say under the evidence."[9]
In Zinnel v. United States Shipping Board Emergency Fleet Corporation (CA 2, 1925), 10 F2d 47, the issue was whether a missing guard rope would have prevented the plaintiff's intestate from being washed overboard. The United States Court of Appeals for the Second Circuit, in reversing a judgment dismissing the complaint, declared (p 49):
"There of course remains the question whether they [the jury] might have also said that the fault caused the loss. About that we agree no certain conclusion was possible. Nobody could, in the nature of things, be sure that the intestate would have seized the rope, or, if he had not, that it would have stopped his body. But we are not dealing with a criminal case, nor are we justified, where certainty is impossible, in insisting upon it. We cannot say that there was no likelihood that a rope three feet above the deck made by the timber would not have saved the seaman. In this connection we note that *171 the ship did not take aboard green water, but that the bluff of the bow broke the force of the sea shipped, which, when it reached the deck load, was made up of white water, and was not big enough to lift a man's body. Considering that such lines were run for the express purpose, among others, of protecting seamen, we think it is a question about which reasonable men might at least differ whether the intestate would not have been saved, had it been there."
So too here, Sidney Mills did not have the burden of establishing through independent evidence that he would assuredly have grasped the railing and checked his fall.
In Davis our Supreme Court also rejected the alternative argument advanced in this case by the defendants, namely that Sidney Mills was contributorily negligent as a matter of law in using the staircase because he had used it many times before and knew that it was not provided with handrails (p 73):
"Plaintiff had used the stairway or ladder for a number of months without injury, and was aware of its condition; but it does not follow that that fact would make its continued use contributory negligence, as matter of law."
In Pollack v. Oak Office Building (1967), 7 Mich App 173, 186, we said:
"The applicable rule as to danger encountered in the exercise of a right or privilege is found in 2 Restatement (2d), Torts, § 473, p 523: `If the defendant's negligence has made the plaintiff's exercise of a right or privilege impossible unless he exposes himself to a risk of bodily harm, the plaintiff is not guilty of contributory negligence in so doing unless he acts unreasonably.'"
*172 The jury could properly find that Mills did not act unreasonably in continuing to use the staircase even though he knew it did not have a handrail.[10]
Reversed and remanded for a new trial. Costs to plaintiffs.
All concurred.

Edgewater Park Company (1963), 369 Mich 320 (per OTIS SMITH, J., three other justices concurring), refusing to extend the doctrine that violation of a statute is negligence per se to a violation of an administrative rule or regulation promulgated under a statute and holding that such a violation is evidence of negligence; similarly, Juidici v. Forsyth Township (1964), 373 Mich 81.

See, also, Ackerberg v. Muskegon Osteopathic Hospital (1962), 366 Mich 596, where the Michigan Supreme Court declared that it was a jury question whether a hospital was negligent in failing to construct a guardrail on its emergency entrance platform.
In the earlier case of Zeglowski v. Polish Army Veterans Association of Michigan, Inc. (1961), 363 Mich 583, relied on by the defendants, the Court did not address itself to the plaintiff's allegation in his declaration that the defendant was negligent in failing to provide a handrail. This is understandable since the plaintiff in that case did not argue in his brief filed with the Supreme Court that a finding of negligence could have been predicated on the absence of a handrail. See Court Rule No 67 (1945), § 1; GCR 1963, 813.1, 854; Bostrom v. Jennings (1949), 326 Mich 146, 156, 157; Chapman v. Buder (1968), 14 Mich App 13, 20.
Compare Mullins v. Wayne County (1969), 16 Mich App 365, 376, where we held that a jury "may find negligence for failure of the road authority to provide railings or barriers needed to keep the road reasonably safe and convenient for public travel," citing a number of decisions of the Michigan Supreme Court.
[8]  It is, of course, true that defendants' violation of the ordinance would not subject them to liability to the plaintiff unless there was a causal relationship between that violation and the plaintiff's damages. See Weber v. Beeson (1917), 197 Mich 607, 610; Stangeis v. Pontiac, Oxford & Northern Railroad Co. (1934), 266 Mich 224, 228, 229.

Cf., also Barringer v. Arnold (1960), 358 Mich 594, 599; Brackins v. Olympia, Inc. (1946), 316 Mich 275, 279, et seq.; Gage v. The Pontiac, Oxford & Northern Railroad Co. (1895), 105 Mich 335, 341, et seq.
The statement in Zeglowski that there was no proof of causal relationship must be read in the light of the holding in that case that as a matter of law there was no negligence.
