In Sparks v. Owens-Illinois, Inc. (1995) 32 Cal.App.4th 461, the defendant manufactured a product known as "Kaylo," which consisted of 13 to 20 percent asbestos, primarily chrysotile. Kaylo was sold in pipe-covering and block forms, and was used for industrial high-temperature thermal insulation. (Sparks, at p. 465.) The plaintiff encountered Kaylo insulation while in the Navy, during a six-month period in which he removed and inspected asbestos insulation on pipes and valves. The insulation was removed by cutting and sawing, which produced sawdust consisting of the insulation material. Regular cleanup procedures involved the use of compressed air and foxtail brooms, both of which generated large amounts of dust. (Id. at p. 466.) Sparks held that the consumer expectations test applied to the plaintiff's claims for products liability based upon design defect because there were no " 'complicated design considerations,' " " 'obscure components,' " or " 'esoteric circumstances' " surrounding the plaintiff's use of Kaylo, which was a common type of asbestos block insulation. Sparks noted that Kaylo was a simple, stationary product in ordinary use that had to be cut and shaped to perform its insulating function; this cutting created large of amounts of asbestos-laden dust during the normal installation, inspection, removal and replacement processes. "The design failure was in Kaylo's emission of highly toxic, respirable fibers in the normal course of its intended use and maintenance as a high-temperature thermal insulation. It is a reasonable inference from the evidence that this emission of respirable fibers, which were capable of causing a fatal lung disease after a long latency period, was a product failure beyond the 'legitimate, commonly accepted minimum safety assumptions of its ordinary consumers.' " (Sparks, supra, 32 Cal.App.4th at pp. 474-475, citing Soule, supra, 8 Cal.4th at pp. 569-570.) Sparks further held that the use of expert testimony was not precluded in cases proceeding on the consumer expectations test because such testimony was useful to the jury in determining that ordinary users of Kaylo during the 1950's and 1960's did not expect to develop a fatal disease from simply breathing Kaylo dust and therefore that the product did not meet the minimum safety assumptions of ordinary consumers.
