Safety Considerations for Application of Spray-On Truck Bed Liners

摘要

Most polyurethane or polyurea spray-on truck bed lining (TBL) products contain MDI, a diisocyanate which can cause irritation and allergic reactions in exposed workers. occupational asthma can be caused or made worse by overexposure to MDI. Authorities in Michigan recently investigated the case of a worker who died from an asthmatic attack after applying a TBL. To protect TBL applicators and nearby workers, a comprehensive approach including medical considerations, engineering controls, work practices and proper use of personal protective equipment is recommended.
