Plaintiff drove his ear to defendants’ tire shop, removed one of the wheels and took it and a spare tire into the shop for a tire change. Defendant Fred Lowery removed the old tire and was installing the spare when the head of the hammer he was using flew off and hit plaintiff in the face. Verdict and judgment were for defendants.
Plaintiff’s principal claim upon this appeal is the failure of the trial court to give his requested instructions on res ipsa loquitur. Our examination of the record convinces us there was sufficient evidentiary basis for the giving of instructions on that subject and that it was prejudicial error to give none. 1
There is no dispute that the head of the hammer did fly off. There is a dispute about plaintiff’s position at the time. Plaintiff testified he was standing about 8 or 9 feet away, and that no one had told him to stand further back or go *566 somewhere else. Lowery testifiеd that plaintiff “was knelt down, squatting” about 3 or 4 feet away, and had been told he had better move. Plaintiff testified that he requested tire irons be used in mounting the tire because sometimes a hammer will injure the bead. Lowery testified that no such request was made, and that a hammer such as was used would not damage the bead while a tire iron might. There was also some dispute as to the exact type of hammer that was used. Defendant produced a mallet with one rubber end and one metal end. Plaintiff testified that the hammer head which struck him had one blunt rubber end and a steel claw on thе other end. Plaintiff did not know which portion of the hammer struck his face.
Lowery testified that if the handle of a hammer dries out, or if the steel wedge that is put in for the purpose of tightening the head on the hammer comes out, the head becomes loose. Usually a person can tell by the feel of the hammer while he is using it whether the head has become loosened. However, this particular time he did not detect the loosening, or else he would have fixed it immediately. Prior to plaintiff’s accident, Lowery had never had an experience where he had nо advance warning of the head becoming loosened.
Defendant Newby, who had had several years’ experience as a service station attendant testified that this was the first time he could remember a hammer head flying off in his place of business and that it was almost impossible for a tight head to fly off.
Here is evidence of the existence of the three factors which bring the doctrine of res ipsa loquitur into play: “ (1) the accident must be of a kind which ordinarily does not occur in the absence of someone’s negligence; (2) it must have been caused by an agency or instrumentality within the exclusive control of the defendant; and (3) it must not have been due to any voluntary action or contribution on the part of the plaintiff.”
(Barrera
v.
De La Torre,
Defendants contend that the last two conditions are not met in this case because “no harm would have befallen plaintiff had he merely exercised his own wits and knowledge as a craftsman and stood to either side of the line of downward swing of the hammer he was watching.” The only case they
*567
cite is
Weddle
v.
Heath,
Zentz
v.
Coca Cola Bottling Co.,
In
Stanford
v.
Richmond Chase Co.,
Here, too, a reasonable man could conclude that standing 8 or 9 feet away from a person using a hammer would be a safe place to stand and that plaintiff’s actions did not contribute to the accident in the sense that this condition is meant in res ipsa cases.
As to the other conditions, if plaintiff’s position is not considered a “cause” of the accident, it is clear that the accident was caused by an instrumentality within the exclusive control of the defendant. There is no suggestion in the evidence that there was anything unusual or defective about the tire that could have caused the hammer head to fly off. And there was testimony of defendants themselves indicating that the accident does not usually occur in the absence of negligence. Defendant Lowery testified that although it is not unusuаl for hammer heads to loosen, usually a person can tell by the feel of the hammer during its use that it is loosening. Defendant Newby testified that it was almost impossible for a tight head to fly off. The conclusion could be drawn from Lowery’s testimony that he did not feel the head loosening, that this was a very peculiar hammer which loosened and flew apart within the space of a single stroke. However, the inference that he was not paying close enough attention to his work seems the more probable one. From the evidence a jury reasonably could infer that аn accident such as here took place probably would not have occurred in the absence of negligence, We conclude it was a ease appropriate for the giving of an instruction on res ipsa loquitur.
Defendants further contend that plaintiff’s requested instructions incorrectly stated the law, as an additional reason why their refusal was proper. Their arguments consist of bare assertions without citation of a single ease.
*569
Plaintiff’s first instruction*

on this subject is a statement of the general principles governing the defendant’s showing in a res ipsa case substantially as expressed in
Dierman
v.
Providence Hospital,
Defendants argue that the instruction puts the ultimate burden of proof on the defendants, contrary to the correct rule that the res ipsa doctrine only shifts the burden of going forwаrd with the evidence. In the Dierman case, supra, the statement used in this instruction was quoted from the Bourguignon ease to support the following propositions: “This is not to say that a defendant in a res ipsa loquitur case has the burden of proving himself free from negligence. It is not to say that a defеndant must in every case produce evidence of the actual cause of the accident. It is not to say that the question of the sufficiency of a defendant’s explanation—or, if he cannot explain, the sufficiency of his evidence of due care and of impossibility of explanation—is not ordinarily for the jury.” (P. 295 of 31 Cal.2d.) It would appear that to the Supreme Court the statement has the very meaning which defendants criticize it for not having.
The second proposed instruction 3 is criticized for not taking into account plaintiff’s possible contributory negli *570 gence. This instruction merely states that an inferеnce of defendant’s negligence arises. The jury was fully instructed on contributory negligence. To combine the instructions would only create confusion.
In addition, defendants say that the last sentence of the first paragraph of this instruction requires the inference to be “overcome” by the defendants and thus would east upon them the burden of proving by a preponderance of evidence they were not negligent,- also, that it is inconsistent with the remainder of the instruction and would, therefore, create confusion.
The word “overcome” does not necessаrily have such a meaning. As said in
Odden
v.
County Foresters etc. Board,
The third proposed instruction is also objected to on the ground that it states nothing about plaintiff’s possible contributory negligence, an argument not well taken for reasons already indicated.
The fourth proposed instruction is BAJI No. 206-B.

The form of this instruction was approved in
Hinds
v.
Wheadon,
In view of these conclusions, it is unnecessary to consider other points discussed by the pаrties upon this appeal.
The judgment is reversed.
Peters, P. J., and Bray, J., concurred.
Notes
In their brief, defendants claimed there was no basis for application of the doctrine of res ipsa loquitur.
During the oral argument, they conceded there was such a basis but claimed that plaintiff was not prejudiced by the failure to instruct on that subject because, they asserted, the inference of negligence upon their part was overcome by their testimony.
The fallacy of that argument is that, under the circumstances of this case, it was for the jury, under adequate instructions, to consider all of the evidence and determine whеther the inference had in fact been overcome; not for a court to determine that question as a matter of law.
"You are instructed that the accident in this case is of such a character that it speaks for itself. Under such circumstances, the defendants will not he held blameless except under a showing either (1) of a satisfactory explanation of the accident; that is, an affirmative showing of a definite cause for the accident, in which cause no element of negligence on the part of the defendants inheres, or (2) of such carе in all possible respects as necessarily to lead to the conclusion that the accident could not have happened from want of care, but must have been due to some unpreventable cause, although the exact cause is unknown. In the latter case, inаsmuch as the process of reasoning is one of exclusion, the care shown must be satisfactory in the sense that it covers all causes which due care on the part of the defendants might have prevented.”
”It is only necessary for the plaintiff, in order to establish a prima faсie ease, to prove the fact of the accident and the injuries caused thereby. Having done this, he may rest, for the inference then arises that the accident occurred through the negligence of the defendants, and the burden of explaining that defendants were not negligent is then cast upon them. In order to overcome this inference of negligence, the defendants must show that the accident was not caused by their negligence *570 or was a result of an inevitable casualty, or of some cause wMeh human care and foresight could not prevеnt.
‘ ‘ The rule of res ipsa loquitur is not merely a rule of evidence shifting the burden of going forward with proof, for the inference of negligence under the rule does not disappear when met with substantial credible evidence of due care. It remains in the case throughout, to be given cоnsideration by the jury in your weighing of the whole case.
"I instruct you that such an inference of negligence is in itself sufficient to satisfy the burden placed upon plaintiff to prove his case by a preponderance of the evidence.”
The instruction is referred to in defendant’s brief as "garbled,” but the only apparent change is the substitution of ‘* **"reasonable care and diligence” for "ordinary care and diligence.”
