Silica Awareness

OSHA is issuing two standards to protect workers from exposure to respirable crystalline silica- one for construction , and the other for general industry and maritime- in order to allow employers to tailor solutions to specific coinditions in thier workplaces.

About two million construction workers are exposed to respirable crystalline silica in over 600,000 workplaces.  OSHA estimates that more than 840,000 of these workers are exposed to silica levels that exceed the new permissable exposure limit ( PEL).

Crystalline silica is an important industrial material found abundantly in the earth’s crust. Quartz, the most common form of silica, is a component of sand, stone, rock, concrete, brick, block, and mortar. Materials containing quartz are found in a wide variety of workplaces.

Silica dust is hazardous when very small (respirable) particles are inhaled. These respirable dust particles can penetrate deep into the lungs and cause disabling and sometimes fatal lung diseases, including silicosis and lung cancer, as well as kidney disease. Exposure can occur during common construction tasks such as using masonry saws, grinders, drills, jackhammers and handheld chipping tools.

Local 15 is meeting the new OSHA standards by offering Silica Awareness Training.  Classes will be held in the following dates:
