Is there any case law where a plaintiff relied solely on evidence that supports their claim of exposure to asbestos products?

product itself; and it is not uncommon for asbestos plaintiffs to rely on their own testimony or testimony by family members or coworkers, i.e., from individuals other than experts, or on business records detailing the purchase and placement of asbestos products at jobsites or in work environments. Even " circumstantial evidence ... sufficient to support a reasonable inference " of exposure may defeat summary judgment. ( Casey v. Perini Corp. (2012) 206 Cal.App.4th 1222, 1237, 142 Cal.Rptr.3d 678.)
