WASHINGTON D.C. — The Occupational Safety and Health Administration (OSHA) has issued interim enforcement guidance to help combat supply shortages of disposable N95 filtering face piece respirators (N95 FFRs). The action marks the department’s latest step to ensure the availability of respirators and follows President Donald Trump’s Memorandum on Making General Use Respirators Available.

Due to the impact on workplace conditions caused by limited supplies of N95 FFRs, employers should reassess their engineering controls, work practices and administrative controls to identify any changes they can make to decrease the need for N95 respirators.

If respiratory protection must be used, employers may consider use of alternative classes of respirators that provide equal or greater protection compared to an N95 FFR, such as National Institute for Occupational Safety and Health (NIOSH)-approved, non-disposable, elastomeric respirators or powered, air-purifying respirators. 

When these alternatives are not available, or where their use creates additional safety or health hazards, employers may consider the extended use or reuse of N95 FFRs, or use of N95 FFRs that were approved but have since passed the manufacturer’s recommended shelf life, under specified conditions.

This interim guidance will take effect immediately and remain in effect until further notice. This guidance is intended to be time-limited to the current public health crisis. Visit OSHA’s coronavirus webpage regularly for updates.
