Marcella Fletcher appeals from the order of the State Court of Thomas County granting summary judgment to Water Applications Distribution Group, Inc. (“Water Applications”) and CertainTeed Corporation (“CertainTeed”) in this suit for personal injury arising out of the alleged negligence of the appellees, a vendor and manufacturer, respectively, of asbestos-containing cement water pipe. Fletcher averred that she was exposed to her father’s asbestos dust-contaminated work clothing between 1960 and 1977 when she was responsible for washing her family’s laundry at home and that, as a result of that exposure, she developed malignant pleural mesothelioma. The trial court granted summary judgment to the appel*694lees, concluding that they owed no duty of care to Fletcher under these circumstances. For the reasons that follow, we affirm in part and reverse in part.
Summary judgment is proper when there is no genuine issue of material fact and the movant is entitled to judgment as a matter of law. On appeal from the grant or denial of a motion for summary judgment, we review the evidence de novo, and all reasonable conclusions and inferences drawn from the evidence are construed in the light most favorable to the nonmovant.
(Citations, punctuation and footnote omitted.) MCG Health v. Barton, 285 Ga. App. 577, 578 (647 SE2d 81) (2007). So viewed, the record shows the following relevant facts.
Fletcher was diagnosed with malignant pleural mesothelioma on August 5, 2012. She produced evidence that the disease is caused by asbestos exposure and has a latency period of approximately 40 years from the time of exposure to the onset of disease. Fletcher deposed that she was exposed to two sources of asbestos during her lifetime: (1) during a 1971 construction project in her family home and (2) during the seventeen years between 1960 and 1977 when she laundered her father’s asbestos dust-contaminated work clothing at home. Fletcher recalled seeing a gray dust on her father’s work clothes that became an airborne “mist” when she shook out his clothing prior to laundering it. Fletcher presented evidence that asbestos dust released from work clothing could remain in the home as a continuing contaminant, exposing a worker’s family members to a risk of mesothelioma.
Fletcher’s father was employed by the City of Thomasville Water & Light Department from 1948 until his retirement in 1983. From 1971 through 1977, her father’s primary job duty was handling, cutting, installing, and repairing water pipe. A city employee testified that Fletcher’s father worked primarily with CertainTeed asbestos-containing cement pipe. When Fletcher’s father cut and beveled the pipes, dust containing asbestos was deposited on his work clothing. At the end of each work day, he wore those contaminated work clothes home.
CertainTeed has been manufacturing asbestos-containing products since 1930. It began manufacturing asbestos-containing water and sewer pipe in 1962. Sales invoices establish that approximately 30,158 linear feet of CertainTeed “Fluid-Tite” asbestos-containing cement pipe was shipped to the City of Thomasville Water & Light Department between 1969 and 1973. The invoices also show that the *695pipe was sold to the City through a local vendor, Davis Meter & Supply Company, the predecessor to Water Applications. The pipes contained approximately 10 to 20 percent asbestos by weight, and they had to be cut and beveled in order to be connected to other pipes.
Fletcher presented evidence in response to the appellees’ motion for summary judgment showing that the dangers, not only to a worker but also to a worker’s family, from work clothing that had been contaminated with toxic substances were known and documented in published occupational health and safety literature as early as 1913. In 1943, the Pennsylvania Department of Labor distributed to industrial employers in the state, including CertainTeed, a “Safe Practice Bulletin” advising employers to have their employees keep their asbestos-contaminated work clothing at work in special lockers. In 1949, CertainTeed joined the National Safety Council, an industry public service organization, and, in 1954, the National Safety Council published articles warning against the dangers of workers carrying toxic substances home to their families on their work clothes. Certain-Teed admitted in a verified interrogatory in another lawsuit “that it became aware at least by 1962, ... if not earlier” that exposure to asbestos fibers was associated with an increased risk of developing certain asbestos-related diseases, including mesothelioma. In 1963, the National Safety Council again warned its members that “contaminated work clothes should not be taken home where a toxic dust could contaminate the home or expose other members of the family.” In 1964, during a conference attended by CertainTeed, researchers presented evidence that mesothelioma was associated not only with occupational exposure to asbestos dust but also to exposure to dust brought home by relatives working with asbestos. In 1972, Occupational Safety and Health Administration (“OSHA”) rules and regulations required employers to provide special clothing for those working with asbestos fibers and to properly isolate those work clothes to prevent the employee’s street clothes from becoming contaminated. Fletcher adduced evidence that neither appellee had placed an asbestos health hazard warning on the asbestos-containing water pipe products during the time of Fletcher’s alleged exposure.
Fletcher sued CertainTeed and Water Applications under theories of negligence. She asserted against both appellees various “general negligence” claims as well a claim for negligent failure to warn of the health risks associated with the product’s use. Fletcher also sued both appellees under a theory of negligence for selling a defective product, asserting that the water pipe was defective because it contained asbestos fibers that were released into the air when the *696pipe was cut.1 CertainTeed and Water Applications both moved for summary judgment, and, following a hearing, the trial court granted the motions, concluding that the appellees did not owe Fletcher a duty of care because she was neither a user nor a consumer of the pipe at issue and because the appellees “could not have reasonably foreseen that [she] would be affected by their product.” It is from this ruling that Fletcher appeals.
To state a cause of action for negligence in Georgia, the following elements are essential: (1) A legal duty to conform to a standard of conduct raised by the law for the protection of others against unreasonable risks of harm; (2) a breach of this standard; (3) a legally attributable causal connection between the conduct and the resulting injury; and, (4) some loss or damage flowing to the plaintiff’s legally protected interest as a result of the alleged breach of the legal duty.

Wessner, 250 Ga. 199, 200 (296 SE2d 693) (1982). “Before negligence can be predicated upon a given act, some duty to the individual complaining must be sought and found, the observance of which duty would have averted or avoided the injury or damage.” (Citations and punctuation omitted.)

Williams, 278 Ga. 888, 889 (608 SE2d 208) (2005). “The duty can arise either from a valid legislative enactment, *697that is, by statute, or be imposed by a common law principle recognized in the caselaw.” Rasnick v. Krishna Hospitality, 289 Ga. 565, 566-567 (713 SE2d 835) (2011). “The existence of a legal duty is a question of law for the court.” Id. at 567.
1. CertainTeed’s duty to Fletcher. Generally, under Georgia negligence law, a product manufacturer “has a duty to exercise reasonable care in manufacturing its products so as to make products that are reasonably safe for intended or foreseeable uses[.]” (Citations omitted.) Chrysler Corp. v. Batten, 264 Ga. 723, 724 (1) (450 SE2d 208) (1994). With respect to product manufacturers, Georgia law recognizes causes of action based on three general categories of product defect: manufacturing defects, design defects, and warning defects. See Banks v. ICI Americas, 264 Ga. 732, 733 (1) (450 SE2d 671) (1994); Chrysler Corp. v. Batten, 264 Ga. at 724 (l).2 The duties owed pursuant to each claim are not coextensive and must be analyzed separately. Chrysler Corp. v. Batten, 264 Ga. at 724 (1).
(a) Manufacturing defect. Generally, a manufacturing defect results from an error specifically in the fabrication process, as distinct from an error in the design process. See J. Kennard Neal, Ga. Products Liability Law § 6:1, n. 8 (4th ed.). Thus, for a manufacturing defect claim, “it is assumed that the design of the product is safe and had the product been manufactured in accordance with the design it would have been safe for consumer use[.]” Banks v. ICI Americas, 264 Ga. at 733 (1). Because a manufacturing defect represents a departure from a product’s design specifications, a manufacturing defect *698may be found when the product at issue is compared “to a properly manufactured item from the same product line.” (Citation omitted.) Id.
The facts alleged in Fletcher’s claim for a manufacturing defect are not consistent with the proposition that, when CertainTeed fabricated the cement water pipe handled by Fletcher’s father, it negligently departed from the design specifications for the pipe and that Fletcher’s injuries arose from such negligent manufacture. Rather, Fletcher contends that an entire product line — the Certain-Teed “Fluid-Tite” water pipe — is defective because it contains asbestos fibers that are released when the pipe is cut. When a plaintiff calls into question the safety of an entire product line, as in this case, the claim is one for a design defect and not for a manufacturing defect. See Division 1 (b), infra. Because Fletcher’s complaint does not set forth facts supporting the existence of a cause of action for a manufacturing defect, the trial court did not err in granting summary judgment to CertainTeed on this claim.
(b) Design defect. As the Supreme Court of Georgia has explained, in a products liability action for defective design,
the focus [under Georgia statutory and case law] is not on use of the product.... [Rather], the proper analysis in a design defect case is to balance the risks inherent in a product design against the utility of the product so designed----The “heart” of a design defect case is the reasonableness of selecting from among alternative product designs and adopting the safest feasible one. Consequently, the appropriate analysis . . . includes the consideration of whether the defendant failed to adopt a reasonable alternative design which would have reduced the foreseeable risks of harm presented by the product.

Corp., 271 Ga. 644, 645 (522 SE2d 467) (1999) (“In a negligent design case, the risk-utility analysis applies to determine whether the manufacturer is liable.”). The risk-utility analysis is
a test balancing the risks inherent in a product design against the utility of the product so designed____[U]nder the risk-utility analysis for the determination whether a manufacturer should be liable for an entire product line, no finite set of factors can be considered comprehensive or applicable under every factual circumstance, since such matters must necessarily vary according to the unique facts of each case.
*699Banks v. ICI Americas, 264 Ga. at 735-736 (1). Generally,
it is for the trier of fact to consider the numerous factors which are pertinent in balancing the risk of the product against its utility or benefit. . . . [Determination of a product’s risks and benefits as a matter of law... will rarely be granted in design defect cases when any of these elements is disputed.
(Citations and punctuation omitted.) Ogletree v. Navistar Intl. Transp. Corp., 271 Ga. at 646. A defendant bears the burden, in seeking a judgment as a matter of law, “to show plainly and indisputably an absence of any evidence that a product as designed is defective.” (Citation omitted; emphasis in original.) Id.
Rather than addressing the issue of whether its product as designed was defective, CertainTeed contends it is entitled to judgment because Fletcher is not within a class of people whose interests are entitled to protection from its conduct, citing CSX Transp. v. Williams, 278 Ga. 888. In that case, the Supreme Court of Georgia “decline [d] to extend on the basis of foreseeability” the duty that an employer owes to provide a safe workplace to its employees to encompass potential liability for injuries sustained by any third party, nonemployee who might come into contact with its employees’ asbestos-tainted work clothing at locations away from the workplace. Id. at 890-891. We conclude, however, that CSX Transp. v. Williams is not controlling when determining whether a manufacturer violated its duty of care in a design defect case. The risk-utility analysis applicable to such claims is not concerned with protecting only specified classes of people. See Jones v. Nordictrack, Inc., 274 Ga. at 115-118; Banks v. ICI Americas, 264 Ga. at 736 (1). Because Certain-Teed failed to carry its burden of showing plainly and indisputably an absence of any evidence that its product as designed was defective under the risk-utility analysis, the trial court erred in granting summary judgment to CertainTeed on Fletcher’s design defect claim. Ogletree v. Navistar Intl. Transp. Corp., 271 Ga. at 647.
(c) Warning defect. “Under Georgia law, a manufacturer has a duty to warn of nonobvious foreseeable dangers from the normal use of its product.” (Citations omitted.) Thornton v. E.I. Du Pont De Nemours & Co., 22 F3d 284, 289 (III) (b) (11th Cir. 1994) (applying Georgia law). See also Chrysler Corp. v. Batten, 264 Ga. at 724 (1) (“[T]he manufacturer of a product which, to its actual or constructive knowledge, involves danger to users, has a duty to give warning of such danger.”) (citations omitted); Fouch v. Bicknell Supply Co., 326 *700Ga. App. 863, 872 (2) (756 SE2d 682) (2014) (accord). The manufacturer’s duty to warn continues even after the product has been sold. See DeLoach v. Rovema Corp., 241 Ga. App. 802, 804 (527 SE2d 882) (2000) (recognizing a manufacturer’s duty to warn consumers of a danger arising from the use of a product based on knowledge acquired after the product is sold). The manufacturer’s duty to warn extends to users, consumers, and purchasers of the product.3 Georgia law also requires a manufacturer to exercise reasonable care to inform third persons of foreseeable dangers arising from the reasonable use for which a product is intended. R & R Insulation Svcs. v. Royal Indem. Co., 307 Ga. App. 419, 427 (3) (705 SE2d 223) (2010). Although, as a practical matter, Fletcher would not have seen warning labels placed on CertainTeed’s pipe, she argues that, if CertainTeed had warned the City or Fletcher’s father (the purchaser and user of the pipe, respectively) of the risks both to the user and to third parties from inhaling asbestos dust released by cutting the pipe, her father would have taken precautions to protect himself, his family, and others from exposure to the asbestos dust. See Daniels v. Bucyrus-Erie Corp., 237 Ga. App. 828, 830 (516 SE2d 848) (1999) (A manufacturer’s warning that is given “to a person in a position such that he may reasonably be expected to act so as to prevent the danger from manifesting itself” may be sufficient to reasonably protect third-party bystanders.) (citation and punctuation omitted).4
Applying this law to the facts of this case, we conclude that whether CertainTeed had a duty to warn of the risks of its asbestos-containing water pipe remains a question for the jury to resolve. Fletcher presented some evidence that, prior to and during the period that Fletcher’s father was actively working with its pipe, CertainTeed had actual or constructive knowledge of the following: (1) asbestos is *701a hazardous substance that causes mesothelioma; (2) asbestos dust may be released from its asbestos-containing cement water pipe during the ordinary use of that product; (3) the asbestos dust may be deposited on the work clothing of those using the pipe; (4) workers who are unaware of the risks of asbestos dust may unwittingly expose others, in this case family members, to that dust. Because the facts adduced with respect to CertainTeed’s knowledge are disputed and because questions concerning foreseeability are typically for the jury, the trial court erred in granting summary judgment to CertainTeed on Fletcher’s negligent failure to warn claim. See R & R Insulation Svcs. v. Royal Indem. Co., 307 Ga. App. at 427-430 (3) (a); Wabash Metal Products v. AT Plastics Corp., 258 Ga. App. 884, 886-887 (1) (575 SE2d 683) (2002).
(d) Miscellaneous “general negligence”claims. Fletcher has asserted other general negligence claims against CertainTeed, e.g., negligent failure to test and negligent failure to recall. However, Fletcher has not challenged the trial court’s grant of summary judgment in favor of CertainTeed with respect to any of these other “general negligence” claims. Thus, with respect to those claims, the trial court’s judgment is affirmed.
2. Water Application’s duty to Fletcher. The record shows that Water Applications (as the successor to Davis Meter & Supply Company) was not involved in the manufacture of the water pipe at issue in this case; rather, it was a vendor. Fletcher obtained records from CertainTeed which show that Water Applications placed the order for the CertainTeed pipe for the City and that the pipe was shipped directly to the City. There is no evidence in the record establishing that Water Applications ever had possession of the pipe. Nor has Fletcher presented evidence from which a jury might infer that Water Applications had actual or constructive knowledge, at the time that it sold the pipe, of the health risks to third persons from asbestos dust released from CertainTeed’s asbestos-containing water pipe.
(a) Manufacturing and design defect claims and other “general negligence” claims. As we held in Division 1 (a), Fletcher has not supported her claim for a manufacturing defect. Further, Fletcher has not challenged the trial court’s grant of summary judgment in favor of Water Applications as to any of the other product liability or “general negligence” claims alleged in the complaint, other than the claim alleging negligent failure to warn. Thus, with respect to those claims, the trial court’s judgment is affirmed.
(b) Negligent failure to warn. “[T]he distributor of a product which, to its actual or constructive knowledge, involves danger to users has a duty to give warning of such danger at the time of sale and delivery.” (Citations and punctuation omitted; emphasis supplied.) *702Farmer v. Brannan Auto Parts, 231 Ga. App. 353, 354 (1) (498 SE2d 583) (1998). Unlike a manufacturer, a seller or a distributor does not have a continuing duty to warn. DeLoach v. Rovema Corp., 241 Ga. App. at 804-805. In this case, Fletcher has presented no evidence from which the factfinder could reasonably infer that Water Applications was aware that the pipe contained no warning labels affixed by the manufacturer. There is no evidence that the pipe was ever in its possession. Further, all of the evidence that Fletcher adduced with respect to the dangers associated with asbestos dust released from the water pipe pertained to knowledge that CertainTeed, as the manufacturer of the product, would have had. Fletcher has not presented evidence from which a jury could infer that, at the time of sale, Water Applications had constructive knowledge of the hazards associated with asbestos dust residue released from CertainTeed’s water pipe. Consequently, the trial court did not err in granting summary judgment to Water Applications on Fletcher’s negligent failure-to-warn claim.
Judgment affirmed in part and reversed in part.
