||A mock up spray room was constructed within the Health and Safety Laboratory with dimensions, ventilation conditions and extraction rates set to represent typical car body spray room conditions. A robotic sprayer was used to simulate paint spraying of car parts under a range of conditions; including spray orientation relative to the extraction duct, spray gun type, ventilation set up and extraction rates. Real-time monitors were used in conjunction with standard methods for airborne isocyanate (NCO) concentration monitoring. The main findings were: high NCO levels are present in spray rooms during spraying; airborne NCO levels were homogeneous throughout the spray room; factors affecting the amount of airborne NCO include gun type, gun condition, spray pattern and NCO formulation; airborne NCO took a significant time to clear the spray room. Other findings are discussed.
