Silica is one of the most common hazards on a worksite, particularly in the construction, oil and gas, manufacturing, and agriculture industries. Silica dust can cause silicosis, a serious and irreversible lung disease. It can also cause lung cancer. Cutting, breaking, crushing, drilling, grinding, or blasting concrete or stone releases the dust.
According to OSHA compliance guidance on r espirable crystalline silica, the silica risk stems from tiny particles (think 100 times smaller than sand on a beach) created from manufacturing and fabrication operations such as cutting, grinding, and abrasive blasting of stone, concrete, sand.
OSHA Construction Standard. On March 24, 2016, OSHA issued a final silica standard for the construction industry. The new standard went into effect on June 23, 2016, and OSHA began enforcement on September 23, 2017. Challenges to the standard were dismissed by the United States Court of Appeals for the District of Columbia Circuit in December 2017.
