When the materials are disturbed or handled, hazardous levels of airborne asbestos fibers may result. People in these areas should take measures to protect themselves and their employees, warns the state Department of Labor and Industries.
Asbestos is a fireproof mineral widely used in building construction and manufacturing processes.
Elevator shafts and pressure vessels frequently are coated or blanketed with sprayed-on fire retardant that contains asbestos. People involved in elevator or pressure vessel maintenance, construction or inspection may encounter deteriorated or disturbed asbestos- containing materials while performing their routine duties. Breathing airborne asbestos has been found to cause respiratory disease and lung cancer. Comprehensive methods for controlling workers' exposure to asbestos are included in the regulations. They include requirements for protective clothing and respirators, techniques for asbestos removal and handling, ways to test for asbestos exposure, and ways to clean up and dispose of materials containing asbestos.
