Oct 25, 2017· New OSHA Silica Testing Requirement in Effect. OSHA has issued two standards ("rules") to minimize exposure to respirable crystalline silica. One rule applies to construction trades, and the other for general industry and maritime workplaces. This blog focuses on the new OSHA Silica Testing requirements for the construction industry.
Crystalline silica is a common mineral found in many naturally occurring materials and used in many industrial products and at construction sites. Materials like sand, concrete, stone and mortar contain crystalline silica. Crystalline silica is also used to make products such as glass, pottery, ceramics, bricks, concrete and artificial stone.

Whenever materials containing crystalline silica — masonry, brick, stone, concrete, glass — are sawn, drilled, chipped or crushed, silica dust is created and released. Silica sand is especially problematic because it is grainy and dusty, even in its natural state. Most particles are 100 times smaller than sand found on beaches. Silica Exposure
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.
