The United States Department of Labor's Occupational Safety and Health Administration (OSHA) announced a final rule to improve protections for workers exposed to respirable silica dust.
The rule will curb lung cancer, silicosis, chronic obstructive pulmonary disease and kidney disease in workers by limiting their exposure to respirable crystalline silica.
"More than 80 years ago, labour secretary Frances Perkins identified silica dust as a deadly hazard and called on employers to fully protect workers," said U.S. secretary of labour Thomas E. Perez. "This rule will save lives. It will enable workers to earn a living without sacrificing their health. It builds upon decades of research and a lengthy stakeholder engagement process — including the consideration of thousands of public comments — to finally give workers the kind of protection they deserve and that Frances Perkins had hoped for them."
OSHA estimates that when the final rule on Occupational Exposure to Respirable Crystalline Silica becomes fully effective, it will save more than 600 lives annually and prevent more than 900 new cases of silicosis — an incurable and progressive disease — each year. The agency also estimates the final rule will provide net benefits of about $7.7 billion per year.
"The previous exposure limits were outdated and did not adequately protect workers," said assistant secretary of Labour for Occupational Safety and Health David Michaels. "Limiting exposure to silica dust is essential. Every year, many exposed workers not only lose their ability to work, but also to breathe. Today, we are taking action to bring worker protections into the 21st century in ways that are feasible and economical for employers to implement."
About 2.3 million men and women face exposure to respirable crystalline silica in their workplaces in the U.S., including two million construction workers who drill and cut silica-containing materials such as concrete and stone, and 300,000 workers in operations such as brick manufacturing, foundries and hydraulic fracturing. Most employers can limit harmful dust exposure by using equipment that is widely available — generally using water to keep dust from getting into the air or a ventilation system to capture dust where it is created.
The final rule will improve worker protection by:
•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, such as 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 metre.
