The trial court erred in handling the allocation of fault issue in this asbestosis case. It should have included on the special verdict form all parties potentially liable for causing plaintiff’s exposure to asbestos, including asbestos-containing joint tape manufacturers as well as auto brake manufacturers. Plaintiff was an auto repairman but admitted that he had been present during a home renovation in which joint tape was used. Plaintiff’s answers to interrogatories about his exposure to asbestos from joint tape were admissible against him even if plaintiff lacked the expertise to testify competently to those facts. The trial court also erred in refusing defendant’s proposed instruction that as owner of an auto repair shop, plaintiff owed a duty to his workers to protect them against workplace hazards, such as asbestos. Failure to give the instruction was prejudicial since it prevented defendant from arguing that as an employer plaintiff bore a greater share of fault for the asbestos dust to which he and his workers were exposed.
