Workers are exposed to hazardous substances that can cause skin irritation, loss of vision, respiratory damage, cancer, heart disease, and other chronic illnesses. When employee exposure to airborne contaminants exceeds OSHA permissible levels, controls must be instituted to reduce exposures to acceptable limits. Reducing contaminants through proper engineering controls and work practices is the first priority for the protection of personnel. This includes isolation of the process, use of less toxic materials, and local exhaust ventilation. If these controls are not feasible then suitable respiratory equipment must be provided to protect workers from exposure to hazardous airborne contaminants.
Training is a critical part of respirator use.
Topics discussed include the OSHA Respiratory Program , types of respirators, medical evaluations, fit testing procedures, proper use of respirators, maintenance procedures, respiratory hazards, and precautions.
