Washington — Seeking “uniformity” in the enforcement of its silica standards, OSHA has published an instructional directive for its compliance safety and health officers.

Dated June 25, the directive outlines inspection procedures for addressing respirable crystalline silica exposures in general industry, maritime and construction. The directive guides OSHA inspectors on the enforcement of the silica standards’ requirements, which include:

  • Methods of compliance
  • Exposure assessments
  • Table 1 tasks and specified exposure control methods
  • Housekeeping
  • Communication of hazards
  • Respiratory protection
  • Regulated areas
  • Recordkeeping
  • Employee information and training
  • Medical surveillance

“The directive also provides clarity on major topics, such as alternative exposure control methods when a construction employer does not fully and properly implement Table 1, variability in sampling, multiemployer situations, and temporary workers,” a June 26 agency press release states.

The standards call for a permissible exposure limit of 50 micrograms per cubic meter of air over an 8-hour time-weighted average. As of June 23, general industry and maritime employers must offer medical surveillance to all employees who are exposed to the silica standard’s “action level” of 25 micrograms per cubic meter for 30 or more days a year.

Hydraulic fracturing operations in the oil and gas industry have until June 23, 2021, to comply with OSHA requirements for the standard’s engineering controls.

U.S. Department of Labor Issues Guidance to Ensure Uniform Enforcement of Silica Standards

WASHINGTON, DC – The U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) recently issued a compliance directive designed to ensure uniformity in inspection and enforcement procedures when addressing respirable crystalline silica exposures in general industry, maritime, and construction.

The new directive provides OSHA compliance safety and health officers with guidance on how to enforce the silica standards’ requirements, including:

  • Methods of compliance;
  • Table 1 tasks and specified exposure control methods;
  • Exposure assessments;
  • Housekeeping;
  • Respiratory protection;
  • Regulated areas;
  • Recordkeeping;
  • Employee information and training;
  • Medical surveillance; and
  • Communication of hazards.

The directive also provides clarity on major topics, such as alternative exposure control methods when a construction employer does not fully and properly implement Table 1, variability in sampling, multi-employer situations, and temporary workers.

OSHA began enforcing most provisions of the construction standard in September 2017, with enforcement of the requirements for sample analysis starting in June 2018. Enforcement of most of the general industry and maritime standards began in June 2018, with enforcement of some medical surveillance requirements commencing on June 23, 2020. On June 23, 2021, OSHA will begin enforcing requirements for engineering controls for hydraulic fracturing operations in the oil and gas industry.

Under the Occupational Safety and Health Act of 1970, employers are responsible for providing safe and healthful workplaces for their employees. OSHA’s role is to help ensure these conditions for America’s working men and women by setting and enforcing standards, and providing training, education and assistance.

U.S. Department of Labor’s OSHA Requests Information on Table 1 of the Silica Standard for Construction

WASHINGTON, DC – The U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) is requesting information and comment on Table 1 of the agency’s Respirable Crystalline Silica Standard for Construction. OSHA seeks information on additional engineering and work practice control methods to effectively limit exposure to silica for the equipment and tasks currently listed on Table 1. The agency is also requesting information about other construction equipment and tasks that generate silica that it should consider adding to Table 1, along with information about their associated engineering and work practice control methods.  Read more»
