In this products liability case arising out of exposure to asbestos, we consider anew whether a manufacturer has a duty to warn about the risk of harm from exposure to asbestos-containing replacement parts integral to the function of the manufacturer's product, even if the manufacturer did not fabricate or distribute the replacement parts. We conclude that a duty to warn exists when the manufacturer's product contains asbestos components, which are integral to the function of the product, and the manufacturer is aware that routine periodic maintenance of its product will require the replacement of those components with other asbestos-containing parts.
In light of our determination that a manufacturer's product includes any replacement parts necessary to its function, defendants' duty to warn extends to any danger created by those replacement parts. A careful review of the record reveals plaintiff presented sufficient evidence detailing his exposure to asbestos, either from original parts supplied by defendants or replacement parts required for the function of defendants' products, to create issues of fact as to all defendants. The panel, therefore, reverses the orders granting summary judgment in favor of defendants and remands for trial.
