Facts to Know About the Silica Standard

The new Silica Standard will go into effect on June 23, 2018 for General Industry. The new standard will reduce the permissible silica exposure level an employee can be exposed to over an 8-hour time weighted average from 100 micrograms per cubic meter to 50 micrograms per cubic meter. The new standard also established an action level of 25 micrograms per cubic meter. OSHA believes the new standard is needed to reduce the number of employees that develop silicosis. OSHA has outlined their requirements in the new standard 1910.1053. The fall standard can be reviewed in detail on the OSHA website at www.OSHA.gov. The following is a condensed version of these requirements:

  • Employers shall ensure that no employee is exposed to airborne concentrations of respirable crystalline silica in access of 50 micrograms per cubic meter ug/m3 for an 8-hour work shift.
  • The employer shall assess the exposure level of each employee who is, or may reasonably be expected to be, exposed.
  • Employees must be notified of the results of the industrial hygiene monitoring within 15 days of the employer receiving the results.
  • Whenever an exposure assessment indicates that employee exposure is above the 50 micrograms per cubic meter, the employer shall describe in a written notification, the corrective action that is being taken to reduce employee exposure to at or below 50 micrograms per cubic meter level (PEL).
  • Areas where employee exposure is or can be above the PEL, the employer shall establish a regulated area.

Methods of Compliance – The first option is engineering and work practice controls. Where these don’t fully reduce the exposure level, respiratory protection is to be provided.

Written Exposure Control Plan – The employer shall establish and implement a written exposure control plan that contains at least the following:

  • A description of tasks that involve exposure to silica
  • Engineering controls, work practices, and respiratory protection
  • Housekeeping measures
  • Make the plan available at no cost
  • Annual review of plan

Housekeeping – The employer shall not allow dry sweeping or dry brushing, or wet sweeping. The use of a vacuuming system with a HEPA filter or other safe methods are to be used that minimize the likelihood of exposure. Compressed air shall not be used to clean clothing or other surfaces where such activity could result in employee exposure. If required, respiratory protection shall be provided meeting standard 1910.134.

Medical Surveillance – Starting on June 23, 2018, employees exposed to silica at or above the 50 micrograms per cubic meter for more than 30 days a year, must be offered medical evaluations. Starting on June 23, 2020, employees exposed to silica at or above the action level of 25 micrograms for 30 days or more must be given medical evaluations.

Communication – The employer is to include silica in their Hazard Communication Program and ensure employees have access to labels on products that contain silica and their Safety Data Sheets. All employees exposed to or likely to be exposed to silica, are to be trained in accordance with the provisions of the Hazard Communication Standard.

Signs shall be posted at the entrance to regulated areas that read:
“Danger: Respirable Crystalline Silica May Cause Damage to the Lungs”
“Authorized Personnel Only: Wear Respiratory Protection in the Area”

Employee Information and Training – The employer shall ensure that each employee covered by this standard can demonstrate knowledge in the following:

  • The Health Hazards of Silica
  • Specific tasks that could result in exposure
  • Specific measures the employer is taking to reduce exposure to silica
  • The content of this standard
  • Purpose and description of the medical surveillance program
  • A copy of the standard is to be readily available to all employees without cost.

Recordkeeping – Everything the employer does to comply with this standard must be documented and records maintained.

If you haven’t started the review of air monitoring of projected tasks, you should begin that process, so your company will be in full compliance on June 23, 2018.
