OSHA Silica Dust Regulations
OSHA Silica Dust Regulations

PROTECT YOURSELF & YOUR EMPLOYEES

The Occupational Safety and Health Administration (OSHA) has issued a final rule to curb lung cancer, silicosis, chronic obstructive pulmonary disease and kidney disease in Americaʼs workers by limiting their exposure to respirable crystalline silica.

ENSURE JOBSITE COMPLIANCE

According to OSHAʼs website, the good news is that silicosis is 100% preventable! While using power tools with a dust attachment/accessory and dust extractors with the right filter, exposure to silica can be drastically reduced.

KEY PROVISIONS

  • Reduces the permissible limit (PEL) to 50 μg/m3 (micrograms of silica per cubic meter of air), averaged over an eight-hour day.
  • Requires employers to use:
    • Engineering controls (such as water or ventilation) to limit worker exposure to respirable silica dust to the PEL
    • Provide respirators when engineering controls cannot adequately limit exposure
    • Limit worker access to high exposure areas
    • Develop a written exposure control plan
    • Train workers on silica risks and how to limit exposures
    • Provide medical exams to monitor highly exposed workers and gives them information about their lung health
  • Establish and implement a written exposure control plan to identify tasks that involve exposure and methods used to protect workers, including procedures to restrict access to work areas where high exposures may occur. Also, employers need to designate a competent person to implement the written exposure control plan.
  • Provides flexibility to help employers — especially small businesses — protect workers from silica exposure.

The new standard went into effect on September 23, 2016, and employers are required to comply with all obligations of the standard. OSHA enforcement dates differ by state and can be referenced by visiting https://www.osha.gov/dcsp/osp/index.html .

If your state does not have their own state plan, OSHA federal silica regulations will apply.
