Does a supplier have a duty to warn their customers of the presence of asbestos in their products?

⁹ In addition to users of finished products incorporating the raw material, employees of the purchaser may also encounter the raw material in their work. The question there is whether the supplier's duty to warn extends to its customers' employees. (See Schwoerer v. Union Oil Co. (1993) 14 Cal.App.4th 103, 110111, 17 Cal.Rptr.2d 227.) Different considerations may apply in the employer-employee context, and we express no view on how principles discussed in this opinion may apply there.
