OSHA Silica Rule

OSHA’s new Respirable Crystalline Silica Rule is now in effect

 

OSHA Silica

What you need to know to be compliant with the New OSHA Crystalline Silica Rule:

The previous OSHA Crystalline Silica standard had not been updated in over 40 years. The agency determined that silica dust exposure at the previous levels resulted in a significant health risk of developing silicosis and other lung or kidney diseases. The new OSHA silica standard for PEL limits exposures to 50 micrograms of Respirable Crystalline Silica (RCS) per cubic meter of air, averaged over an 8-hour work day. 

In order to keep exposure at or below the PEL, using engineering controls and work practices such as local exhaust ventilation systems or wet cutting is recommended. If these practices do not sufficiently lower RCS levels, the use of respirators is required. As industry leaders Seton offers a full range of safety product including warning signs, barricades, and respirators to help you work safely with silica and keep your workplace OSHA compliant.

Frequently Asked Questions


  • What is crystalline silica?

    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. Industrial sand used in certain operations, such as foundry work and hydraulic fracturing (fracking), is also a source of silica.

  • How can exposure to crystalline silica affect workers' health?

    Inhaling very small ("respirable") crystalline silica particles, causes multiple diseases, including silicosis, an incurable lung disease that can lead to disability and death. Respirable crystalline silica also causes lung cancer, chronic obstructive pulmonary disease (COPD), and kidney disease.

  • Who is at risk from exposure to crystalline silica?

    Around 2.3 million workers are exposed to crystalline silica on the job. Simply being near sand or other silica-containing materials is not hazardous. The hazard exists when specific activities create respirable dust that is released into the air.

    Respirable crystalline silica - very small particles typically at least 100 times smaller than ordinary sand found on beaches or playgrounds - is generated by high-energy operations like cutting, sawing, grinding, drilling and crushing stone, rock, concrete, brick, block and mortar; or when using industrial sand. Activities such as abrasive blasting with sand; sawing brick or concrete; sanding or drilling into concrete walls; grinding mortar; manufacturing brick, concrete blocks, or ceramic products; and cutting or crushing stone generates respirable dust.

  • How will the crystalline silica rule protect workers' health?

    The new rule requires that employers use engineering controls - such as ventilation and wet methods for cutting and sawing crystalline silica-contailing materials - to reduce workers' exposure to silica dust. Once the full effect of the rule are realized, OSHA expects it to prevent 600 deaths a year from silica-related diseases - such as silicosis, lung cancer, other respiratory diseases and kidney disease - and to prevent more than 900 new cases of silicosis each year.

  • How many workers will be affected by the rule?

    About 2.3 million workers are exposed to respirable crystalline silica in their workplaces. The majority of these workers, about 2 million, are in the construction industry.
