Chemical Hazards - SPF/Isocyanates | Fire | Confined Spaces | Falls | Medical and First Aid | Electrical | Respiratory Protection | Personal Protective Equipment | Ventilation
Workers in the SPF industry can be exposed to inhalation hazards from Isocyanates and other hazardous chemical vapors or dusts. OSHA requires a hierarchy of controls, under which employers must first implement engineering controls (including elimination, substitution) and/or administrative controls whenever possible. If such controls are not feasible to achieve full compliance, personal protective equipment or any other protective measures must be used to ensure the employees are not exposed to air contaminants above permissible limits. For the spray foam applicator and the helper (who is standing in close proximity and/or may switch duties with spray applicator) a respirator with full face mask should be provided and worn during application and clean-up (more information provided in respiratory protection section). In addition, full saran-coated suits/coveralls with appropriate gloves and shoe-covers should be provided and worn during application and clean-up. It is highly recommended that no skin exposure occurs during these work processes (Bello, 2007).
It is recommended that workers in trimming or sanding operations should be provided and wear appropriate respirators, long sleeves and gloves. Goggles or other eye protective equipment is required.
