This four-hour course is taught by a Board Certified Industrial Hygienist/Certified Safety Professional and is designed to inform individuals of the major requirements of the respirable crystalline silica standard for general industry and maritime.
The proposed standard for general industry and maritime includes provisions for employers to:• Measure the amount of silica that workers are exposed to if it may be at or above an action level of 25 µg/m3 (micrograms of silica per cubic meter of air), averaged over an 8-hour day;
• Protect workers from respirable crystalline silica exposures above the permissible exposure limit (PEL) of 50 µg/m3, averaged over an 8-hour day;
• Limit workers’ access to areas where they could be exposed above the PEL;
• Use dust controls to protect workers from silica exposures above the PEL;
• Provide respirators to workers when dust controls cannot limit exposures to the PEL;
• Offer medical exams-including chest X-rays and lung function tests-every three years for workers exposed above the PEL for 30 or more days per year;
• Train workers on work operations that result in silica exposure and ways to limit exposure; and
• Keep records of workers’ silica exposure and medical exams.
