Title: Preventing Asthma and Death from MDI Exposure During Spray-on Truck Bed Liner and Related Applications
Subject: Expansion on existing related reports, using updated exposure data and control strategies.
Purpose: To alert facility owners, MDI distributors, and workers of the respiratory and dermal hazards associated with the use of aerosolized MDI; to educate health professionals in identifying and eliminating respiratory hazards at spray-on bed liner facilities; and to provide general engineering control designs and work practice recommendations to reduce or eliminate worker exposures to MDI in the spray-on truck bed liner industry. (Note: the bed liner is an isocyanate-based polyurethane or polyurea coating; it contains di- and polyfunctional isocyanates with varying percentages of diphenylmethane diisocyanate (MDI monomer), MDI prepolymers, and polymeric MDI.)
