OSHA Issues Final Crystalline Silica Rule
On March 24, OSHA issued its final rule on Occupational Exposure to Respirable Crystalline Silica. According to OSHA, the final rule is written as two standards, one for construction and one for general industry and maritime. Employers covered by the construction standard have until June 23, 2017 to comply with most requirements. Employers covered by the general industry and maritime standard have until June 23, 2018 to comply with most requirements; additional time is provided to offer medical exams to some workers and for hydraulic fracturing employers to install dust controls to meet the new exposure limit.
The press release announcing the final rule states that worker safety will be improved by:
After a thorough examination of the final rule, IME will provide a more detailed review to the membership.
- Reducing the permissible exposure limit for crystalline silica to 50 micrograms per cubic meter of air, averaged over an eight-hour shift.
- Requiring employers to use engineering controls (such as water or ventilation) and work practices to limit worker exposure; provide respiratory protection when controls are not able to limit exposures to the permissible level; limit access to high exposure areas; train workers; and provide medical exams to highly exposed workers.
- Providing greater certainty and ease of compliance to construction employers – including many small employers – by including a table of specified controls they can follow to be in compliance, without having to monitor exposures.
- Staggering compliance dates to ensure employers have sufficient time to meet the requirements, e.g., extra time for the hydraulic fracturing (fracking) industry to install new engineering controls and for all general industry employers to offer medical surveillance to employees exposed between the PEL and 50 micrograms per cubic meter and the action level of 25 micrograms per cubic meter.
