WebThe employer shall ensure that no employee is exposed to an airborne concentration of asbestos in excess of 0.1 fiber per cubic centimeter of air as an eight (8)-hour time-weighted average (TWA) as determined by the method prescribed in the OSHA standard, or by an equivalent method. Excursion limit. WebThis limit is 0.01 fibers per cubic centimeter (f/cc) of air. If analytical results show fiber levels above 0.01 f/cc, the area is re-cleaned and re-monitored until airborne fiber levels are below the limit. After laboratory analyses show acceptable airborne fiber concentrations, the abatement is considered complete,
