Respirator Fit-Testing Guidelines: April’s Safety & Hygiene Corner

Question: Can you explain the Temporary Guidance for Respirator Fit-Testing in Healthcare from OSHA?

Answer: OSHA has issued temporary enforcement guidance for respirator fit-testing in healthcare during COVID-19 outbreak

This guidance is aimed at ensuring healthcare workers have full access to needed N95 respiratory protection in light of anticipated shortages.

OSHA recommends that employers supply healthcare personnel who provide direct care to patients with known or suspected coronavirus with other respirators that provide equal or higher protection, such as N99 or N100 filtering facepieces, reusable elastomeric respirators with appropriate filters or cartridges, or powered air purifying respirators.

This temporary enforcement guidance recommends that healthcare employers change from a quantitative fit testing method to a qualitative testing method to preserve integrity of N95 respirators. Additionally, OSHA field offices have the discretion to not cite an employer for violations of the annual fit testing requirement as long as employers:

  • Make a good faith effort to comply with the respiratory protection standard;
  • Use only NIOSH-certified respirators;
  • Implement strategies recommended by OSHA and Centers for Disease Control and Prevention for optimizing and prioritizing N95 respirators;
  • Perform initial fit tests for each healthcare employee with the same model, style, and size respirator that the employee will be required to wear for protection from coronavirus;
  • Tell employees that the employer is temporarily suspending the annual fit testing of N95 respirators to preserve the supply for use in situations where they are required to be worn;
  • Explain to employees the importance of conducting a fit check after putting on the respirator to make sure they are getting an adequate seal;
  • Conduct a fit test if they observe visual changes in an employee’s physical condition that could affect respirator fit; and
  • Remind employees to notify management if the integrity or fit of their N95 respirator is compromised.

The temporary enforcement guidance is in effect beginning March 14, 2020 and will remain in effect until further notice.   Appropriate respiratory protection is required for all healthcare personnel providing direct care of these patients.
