Action Level, means a concentration of airborne Respirable Crystalline Silica of 25 μg/m3, calculated as an 8-hour TWA. Exposure to respirable crystalline silica can cause silicosis, lung cancer, other respiratory diseases, and kidney disease. The new permissible exposure limit for respirable crystalline silica – 50 micrograms per cubic meter of air averaged during an 8-hour shift – equals what NIOSH recommended in 1974. It reduces the current permissible exposure limits (PEL) of respirable crystalline silica to 50 micrograms per cubic meter (ug/m 3) of air, averaged over an eight-hour shift. Employers must protect workers from respirable crystalline silica exposures above the PEL of 50 μg/m3, averaged over an eight-hour day. This is the maximum concentration of respirable crystalline silica in air, as an eight-hour time-weighted average, to which an employee may be exposed. Crystalline silica is found in sand, stone, concrete and mortar. Each day, about 295,000 general industry workers and two million construction workers are exposed to respirable crystalline silica. The PEL is dependent on the amount of crystalline silica that is present in the dust. • No worker is exposed to respirable crystalline silica above the Permissible Exposure Limit (PEL) of 50 ug/m3; • An exposure assessment is performed for each task which could expose Russell Hinton workers to respirable crystalline silica at or above the Action Level (AL) 25 ug/m3.
