AIR AND HEALTH MONITORING        Air monitoring is required during the paint mixing process and also on clean up to determine the need for respiratory protection. Health monitoring by doctor to be provided for all workers who previously worked with insufficient controls (half-face respirator and latex gloves) and to painters on an ongoing basis due to the high hazard of the isocyanates in paint.
