Crystalline silica is a common mineral found construct materials like sand, stone, concrete, and mortar. It is also used to make products such as glass, pottery, ceramics, bricks, and artificial stone.

Respirable crystalline silica is very small; particles at least 100 times smaller than ordinary sand and can become airborne when cutting, sawing, grinding, drilling, abrasive blasting, crushing stone, rock, concrete, brick, block, and mortar products. Many activities can result in worker exposures to respirable crystalline silica. Workers who inhale crystalline silica particles are at increased risk of developing serious silica-related diseases.

To protect workers exposed to respirable crystalline silica, OSHA has issued two new respirable crystalline silica standards, one for construction industry, and one for general industry and maritime. OSHA has begun enforcing most provisions of the standard for construction industry on September 23, 2017. OSHA will begin enforcing most provisions of the standard for general industry and maritime on June 23, 2018. Washington State has a standard for respirable crystalline silica outlined in WAC 296-840, currently in draft form. WA State plans to implement the standard soon, information can be found here

In this course, you will learn about the basics of Respirable Crystalline Silica encountered during many construction activities. This course will identify the basic health hazards associated with exposures to respirable crystalline silica, the common construction tasks that may result in exposures, and engineering control measures that employers may implement to protect workers from exposure. The course will also include basic PPE and air monitoring techniques for crystalline silica. Students will learn about the new OSHA standards concerning respirable crystalline silica and WA State new standard on respirable crystalline silica including how to recognize what a “competent person” for respirable crystalline silica means.

Classes are offered as custom client requested classes all over Washington State, including Spokane, Seattle, Auburn, and many other city locations including the states of Oregon, Idaho, & Montana.

This class is 4 hours long and costs $150/student.
