Civil Model Jury Charge 5.40C Failure to Warn/Instruct

5.40C Failure to Warn/Instruct[1]

(Approved 3/00; Revised 10/01)


Let me now discuss the law governing the plaintiffs claim of failure to warn.

If a product fails to contain an adequate warning or instructions, it is defective. [Plaintiff] says the [Product] did not contain an adequate warning or instruction because [insert short factual description of plaintiffs contention why the warning was inadequate]. [Defendant] says the [Product] did contain an adequate warning or instruction because [insert short factual description].

The [Defendant] as the manufacturer or seller of a product had a duty to provide adequate warnings or instructions about the dangers the [Product] may present. [Defendant] had this duty even if the [Product] were perfectly designed and manufactured. To decide the plaintiffs failure to warn claim you must determine what warnings and instructions the defendant provided and whether those warnings and instructions were adequate.

Lets talk about what a warning or instruction is. Warnings or instructions may consist of statements that a product should not be used at all under certain circumstances, that it should be used only in a particular way, or that it should be used with particular care. Warnings or instructions may be in the form of words, symbols or pictures. They must be in a form which will effectively convey the information essential to make the use of the product reasonably safe.

To be adequate, the warning or instruction must be the kind of warning or instruction which a reasonably prudent manufacturer or seller in the same or similar circumstances would have provided to people intended to use the product. Adequate information may be required to be given to others in the chain of distribution of the product such as from the manufacturer and the seller to the buyer, or from the manufacturer and the seller directly to the user.[2] An adequate warning or instruction will communicate sufficient information on the dangers of the product and how to use the product safely. When deciding whether the information provided is adequate, you should take into account the characteristics of the people reasonably expected to use the product and ordinary common knowledge.[3]

In deciding whether the warning or instruction given in this case was adequate, you must assume the [Name of Defendant Manufacturer/Seller] knew of the dangers of the [Product] at the time [Product] was sold/distributed. With that assumption you must then decide whether the [Defendant] acted in a reasonable, prudent manner in marketing the [Product] without any warnings/with the particular form of warning that was provided.

[Charge when applicable:]

In this case [Defendant] contends that [describe danger] was not knowable at the time the [Product] was manufactured/sold. If [Defendant] proves that the danger in question was not knowable by it at the time of manufacture or sale, then it had no duty to warn of the danger and cannot be held liable for failure to do so.[4] In evaluating this defense of [Defendant], you may consider evidence relating to [Defendants] knowledge of the danger of the [Product]. A duty to warn arises if [Defendant] (the manufacturer/seller) actually knew or should have known of the need to issue a particular warning.

In determining what [Defendant] should have known, you must understand that the law requires a manufacturer/seller to keep reasonably familiar with and to know reliable information generally available or reasonably obtainable in the industry. In that regard, [Defendant] is deemed to be an expert in its field.[5] This information may come from experts and literature in the field. Moreover, information from other sources such as complaints from users, sellers or distributors of an untoward effect of a product may be sufficient to require an appropriate warning.

[Charge when applicable:]

A manufacturer or seller such as [Defendant] may also have responsibility to warn purchasers and consumers of dangers discovered after the product was sold/distributed. This duty arises when subsequently obtained knowledge, both actual or constructive, was available either at the time of distribution or in sufficient time before the accident/injury so that an effective and reasonable supplemental warning could have been given. In this regard it is the defendant who must prove that the information about the danger was not reasonably available or obtainable either at the time of distribution or in sufficient time before the accident/injury.[6]

To establish a claim of failure to warn, [Plaintiff] must prove all of the following elements by a preponderance (greater weight) of the credible evidence:

l. That the [Product] failed to contain an adequate warning/instruction.


2. That the failure to adequately warn/instruct existed before the [Product] left the control of the [Defendant].


3. [Use only when misuse or intentional alteration is an issue and use only applicable portion.] That when the accident happened the [Product] was not being misused, or it had not been substantially altered in a way that was not reasonably foreseeable.

[Plaintiff] must prove that at the time of the accident the [Product] was being used properly for its intended purposes or for an intended or reasonably foreseeable purpose. To prove this, plaintiff must show that the product was not being misused in a way that was neither intended nor was reasonably foreseeable. In this case, the [Defendant] contends that at the time of the accident the [Product] was being misused. [Set forth a brief factual description of this dispute.]

[Plaintiff] must also show that when he/she used the [Product], it had not been substantially altered since it left [Defendants] control. A substantial alteration is a change or modification made to the product after it was manufactured or sold which both alters the design or function of the product and has a significant or meaningful effect on the products safety when used.[7] In this case the defendant contends that the [Product] was substantially altered. [Set forth a brief factual description of this dispute.]

In considering this issue, you must determine whether there has been a subsequent misuse/abnormal use or substantial alteration to the [Product]. If you find that to exist, you must determine whether the misuse/abnormal use or substantial alteration was reasonably foreseeable at the time the product left the control of the [Defendant].

Reasonably foreseeable does not mean that the particular misuse/abnormal use or substantial alteration was actually foreseen or could have been actually foreseen by [Defendant] at the time the [Product] left his/her control.

This is a test of objective foreseeability. You must consider the general experience within the industry when the [Product] was manufactured, sold or distributed. Then decide whether a reasonably careful manufacturer, seller or distributor could have anticipated the misuse/abnormal use or substantial alteration of the [Product].[8] If the alteration reasonably could have been anticipated, and if the alteration made the product not reasonably safe, the defendant is still responsible. [Plaintiff] has the burden to show that a typical manufacturer or seller of the product could foresee that the product would be altered or that despite the alteration the original defect was nonetheless a cause of the injury.[9]

4. That the [Plaintiff] was a direct or reasonably foreseeable user, or a person who might reasonably be expected to come in contact with the [Product].[10]

5. That the [Plaintiff] would have followed an adequate warning/instruction if it had been provided.[11]


[When defendant offers no evidence or insufficient evidence to rebut the heeding presumption, a directed verdict on this issue should be granted.]


[When defendant offers evidence sufficient to rebut the heeding presumption, charge as follows:][12]


In this case, [plaintiffs name] claims that the [products name] was defective because there was no adequate warning/instruction. If you find that the [products name] was defective because adequate warning/instruction was not given, then you must decide whether the lack of an adequate warning/instruction was a proximate cause of the accident.

The [defendants name] has introduced evidence seeking to show that [plaintiffs name] would not have read and followed an adequate warning/instruction even if one had been provided by the defendant.

You have to decide whether plaintiff would have read and heeded a warning/instruction had one been given or that he would not have read and heeded a warning/instruction had one been given.

Plaintiff has the burden to prove by a preponderance of the credible evidence that he/she would have followed an adequate warning/instruction if it had been provided.

6. That the failure to adequately warn/instruct was a proximate cause of the accident/injury.[13]


Proximate cause means that the failure to warn/instruct was a substantial factor which singly, or in combination with another cause or causes, brought about the accident. [Plaintiff] need not prove that this accident could have been anticipated so long as it was foreseeable that some harm could result from the failure to warn/instruct. If an adequate warning/instruction would have reduced the risk of the occurrence of this accident, you may find that its absence was a contributing factor to the happening of this accident. If, on the other hand, the failure to warn/instruct does not add to the risk of the occurrence of this accident and therefore is not a contributing factor to the happening of the accident, then plaintiff has failed to establish that the failure to warn/instruct was a proximate cause of the accident.

[Instruction on intervening cause, where applicable:]

In this case the [Defendant] contends that [set forth defendants contention] was an intervening cause.

An intervening cause is the act of an independent agency which destroys the causal connection between the defect in the product and the accident. To be an intervening cause the independent act must be the immediate and sole cause of the accident. In that event, liability will not be established because the failure to warn/instruct is not a proximate cause of the injury. However, the defendant would not be relieved from liability for its failure to warn/instruct by the intervention of acts of third persons, if those acts were reasonably foreseeable. Where the intervention of third parties is reasonably foreseeable, then there is a substantial causal connection between the product defect and the accident.[14] You must determine whether the [alleged intervening cause] was an intervening cause that destroyed the causal connection between the failure to warn and the accident. If it did, then the failure to warn/instruct was not a proximate cause of the accident.

If [Plaintiff] has proven each element by a preponderance of the credible evidence, then you must find for [Plaintiff].

If, on the other hand, [Plaintiff] has failed to prove any of the elements, then you must find for the defendant.

[When there is a jury question dealing with defendants affirmative defense or contributory/comparative negligence, the next three questions are applicable.]


7. Was the plaintiff negligent?[15]


[Defendant] contends that [Plaintiff] was at fault for the happening of the accident. [Briefly describe contention.]

To win on this defense, [Defendant] must prove that [Plaintiff] voluntarily and reasonably proceeded to encounter a known danger and that [Plaintiffs] action was a proximate cause of the accident. The failure of [Plaintiff] to discover inadequate warnings or instructions or to guard against the possibility of inadequate warnings or instructions is not a defense. Rather, to win on this defense, [Defendant] must prove that [Plaintiff] had actual knowledge of the particular danger presented by the [Product] and that [Plaintiff] knowingly and voluntarily encountered the risk.

8. Was plaintiffs negligence a proximate cause of the injury?


[See Chapter 6 which deals with Proximate Cause.]

9. Comparative Fault; Apportionment of Fault; Ultimate Outcome.


If plaintiff and defendant both are found to be at fault which is a proximate cause of the accident/injury, the jury must compare their fault in terms of percentages. [See Model Civil Charge 7.31.]

[1] See N.J.S.A. 2A:58C-4.

[2] For the extent of this duty, see Michalko v. Cooke Color and Chemical Corp., 89l N.J. 386 (l982).

[3] If the product is a prescription drug, insert the following:

In the case of a prescription drug, the warning must be one that a reasonably prudent manufacturer would have provided to adequately communicate information on the dangers and safe use of the product to physicians, taking into account the characteristics of, and the ordinary knowledge common to, such prescribing physicians.

See N.J.S.A. 2A:58C-4 regarding the effect of FDA approval upon a warning or instruction given for a prescription drug. See also Feldman v. Lederle Laboratories, 125 N.J. 117 (l991).

[4] See Feldman v. Lederle Laboratories, 97 N.J. 429 (l984).

[5] See Feldman, supra, footnote 10.

[6] There is a post-sale duty to warn. See Feldman v. Lederle Laboratories, 97 N.J. 429 (l984); Dixon v. Jacobsen Manufacturing Co., 270 N.J. Super. 569 (App. Div. l994); Seeley v. Cincinnati Shaper Co., Ltd., 256 N.J. Super. l (l992); and New Jersey Product Liability Act, N.J.S.A. 58-l et seq., section four.

[7] See Soler v. Casemaster, Div. of the H.P.M. Corp., 98 N.J. 137 (l984); Brown v. United States Stove Co., 98 N.J. 155 (l984). Note that an issue of alteration arises only if the particular facts indicate a substantial change relating to the safety of the product. Soler, 98 N.J. at 148. Note further that the issue of misuse/abnormal use or substantial alteration, if present in a case, presents considerations bearing upon proximate cause. Id. at 149; Brown, supra, 98 N.J. at 171-174. See also Fabian v. Minster Mach. Co., Inc., 258 N.J. Super. 261 at 277 footnote 5.

[8] Where there is an issue of misuse/abnormal use or substantial alteration, a jury need not consider the presence of a defect unless it resolves the element of foreseeability against the defendant(s). In such a case, the trial judge might consider altering the charge so that misuse/abnormal use or substantial alteration is charged first.

[9] Brown, supra, 98 N.J. at 169.

[10] This may be omitted if not in dispute.

[11] In Coffman v. Keene Corp., 133 N.J. 581 (1993), and Theer v. Philip Carey Co., 133 N.J. 610 (l993), the Supreme Court adopted the heeding presumption which applies to all failure to warn and inadequate warning cases and provides plaintiff with a rebuttable presumption on the issue of proximate cause, i.e., if a warning or instruction had been given, such warning or instruction would have been heeded by plaintiff. In such cases, the burden of production on the issue of proximate cause shifts to the defendant to come forward with rebuttal evidence sufficient to demonstrate that a warning would have made known to plaintiff the danger of the product and not withstanding the knowledge imparted by the warning, plaintiff would have proceeded voluntarily and unreasonably to subject himself or herself to the dangerous product.

If the defendant fails to meet this burden of production, the trial judge shall direct a verdict in plaintiffs favor on this issue of proximate cause.

If the defendant presents rebuttal evidence such that reasonable minds could differ as to whether the warning, if given, would have been heeded by the plaintiff, the defendant has satisfied its burden of production and plaintiff loses the benefit of the presumption. The plaintiff must then carry the burden of proof (persuasion) as to this proximate cause. Sharpe v. Bestop, Inc., 314 N.J. Super. 54 (App. Div. 1998); 157 N.J. 545 (1999).

When the injury is sustained in the work place, the presumption and burden of the defendant is slightly different. There the presumption contains a second tier. The presumption is not only that the employee would have heeded the warning, but additionally that the employer would have heeded the warning and communicated it to the employees and enabled them to take precautions. Theer v. Philip Carey Co., 133 N.J. at 622. The manufacturer/seller may overcome the presumption by proving that the employee or his or her employer would have disregarded an adequate warning. Coffman v. Keene Corp., 133 N.J. at 609. Further, the manufacturer must prove that had an adequate warning been provided, the plaintiff-employee with meaningful choice would not have heeded the warning. Id. A meaningful choice requires that the plaintiff/employee not be in a position where he/she is forced to work with the product or machine or lose their job. Id at 604. See also Facendo v. S.M.S. Concast, 286 N.J. Super. 575 (App. Div. 1996); Graves v. Church & Dwight Co., Inc., 267 N.J. Super. 445 (App. Div. 1993) (a non workplace case).

[12] Caveat: There are two threshold determinations for admissibility of rebuttal evidence to the heeding presumption [viz., proof of habit that involves a risk similar to that not warned of]:

(1) With regard to the substantive proofs necessary to rebut the heeding presumption, it is important to distinguish between habit and character evidence when offered by a product manufacturer to overcome the presumption. Only evidence of a habit related to the specific situation not a character trait may be offered to rebut the presumption. In Sharpe v. Bestop, 34 N.J. Super. 54 (App. Div. 1998); 158 N.J. 545 (1999), the Supreme Court offered the following:

[T]he Advisory Committee [on the Federal Rules] noted in its Comment to Rule 406 [that] habit describes ones regular response to a repeated specific situation. [B]efore a court may admit evidence of habit, the offering party must establish the degree of specificity and frequency of uniform response that ensures more than a mere tendency to act in a given manner, but rather, conduct that is semiautomatic in nature. Simplex, Inc. v. Diversified Energy Systems, Inc., 847 F.2d 1290, 1293 (7th Cir. 1988).

(2) Even after rebuttal evidence of failure to follow warnings in other contexts rises to the level of habit, the trial court must determine whether such evidence is sufficiently similar in character and quality to establish the likelihood of a similar response to the risk or hazard in issue. Sharpe v. Bestop, 158 N.J. at 331-32 (1999). Thus in Sharpe, the Supreme Court gave the example that they would not find that evidence of ones repeated failure to follow a doctors advice to lose weight is sufficiently similar in character and quality to establish the likelihood of a similar response to a safety warning concerning boating waters. (emphasis added) (citing Verdun v. State, Through Dept of Health and Human Resources, 598 So. 2d 1091, 1095 (La. Ct. App.), writ denied, 604 So. 2d 1003 (La. 1992). Id. at 329.

[13] Plaintiff is required to prove that the absence of a warning was a proximate cause of his harm. This is known as product-defect causation. Coffman v. Keene Corp., 133 N.J. 58l, 594 (l993). Further, in some failure to warn cases another kind of causation must normally be proved -- medical causation. Therefore, proximate cause may require two questions:

l. Was the defect (failure to warn) a proximate cause of plaintiffs exposure to the product?

2. Was the exposure to the product a proximate cause of plaintiffs injury?

See Graves v. Church Dwight Co., Inc., 267 N.J. Super. 445, 450 (App. Div. l993). In cases where the plaintiff is dead or otherwise incapable of testifying at trial, see Sharpe v. Bestop, 314 N.J. Super. 54 at 83.

[14] Navarro v. George Koch & Sons, Inc., 211 N.J. Super. 558, 573 (App. Div. l986), and Butler v. PPG Industries, Inc., 201 N.J. Super. 558, 564 (App. Div. l985), may be understood as discussions of a burden of production rather than persuasion. So construed they clearly conform to Brown v. U.S. Stove, 98 N.J. 155 (1984), and prior law. See Fabian v. Minster Mach. Co., Inc., 258 N.J. Super. 261 at 277, footnote 5 and Johansen v. Mikita USA Inc., 128 N.J. 86 (l992).

[15] This defense is not applicable to workplace injuries where the plaintiff, a worker, has performed a task reasonably assumed to be part of the assigned duties. Ramos v. Silent Hoist and Crane Co., 256 N.J. Super. 467 (App. Div. l992) at 478; Suter, supra, 81 N.J. at 167-168; Tirrell v. Navistar, Intl., 248 N.J. Super. at 401-402. In other than a workplace setting, in a product liability case, plaintiffs comparative fault is limited to unreasonably and intentionally proceeding in the face of a known danger. Cepeda v. Cumberland Engineering Company, Inc., supra, 76 N.J. at l86.

I would have it no other way.

Many years ago, I attended a seminar sponsored by the American Bar Association on Law Practice Management.

When you have been injured in an accident or collision, you are worried about who is going to pay your medical bills, lost wages, and other damages. The last thing you want is to be taken advantage of by an insurance company. If you dont protect your rights, you may not be able to make a claim.

Insurance companies have attorneys and adjusters whose goal is to pay you as little as they can. You need a New Jersey personal injury lawyer to fight for you. I am dedicated to helping your recover as much money as possible under the law.

You need an attorney who will work hard to protect your rights, maximize your insurance settlement and minimize the hassles of dealing with the insurance companies. You need an experienced and aggressive New Jersey trial lawyer with PROVEN RESULTS who will fight for you. Having an experienced personal injury lawyer can make the difference between getting what you deserve and getting nothing.

Without the threat of a lawyer who is willing to go to trial and seek a big jury verdict, why would an insurance company pay you what your claim is really worth? Lawsuits can be expensive, and many people do not have the money to pursue their claim. In every case, I advance all costs associated with pursuing your case and I do not ask you for a penny until we recover from the other side.

I am an experienced aggressive trial lawyer and a 3rd degree Black Belt. I am not afraid to take your case to trial if that is what it takes to maximize the amount of money your recover for your personal injury. I offer one-on-one service, and I will not hand your case off to an inexperienced lawyer or a paralegal.

Reduce the stress of making a claim.

Personal injury accidents can turn your life upside down. Making a personal injury claim can be difficult and time consuming. Once I take your case, you can stop worrying about dealing with the insurance companies and focus on recovering from your injuries. I take care of all of the paperwork, phone calls, and negotiations, so you can get on with your life.

p.s. For those clients who are afraid or reluctant to go to Court, KENNETH VERCAMMEN also offers a special -- For Settlement Only -- program. This means that if we are unable to settle with the insurance company, we will not go any further -- unless you want us to. You have my personal assurance that there will be absolutely no pressure and no obligation.

We handle personal injury cases on a contingency fee basis.
