Certified Equipment List

The National Institute for Occupational Safety and Health (NIOSH), under authorization of the Occupational Safety and Health Act of 1970, provides a testing, approval, and certification program assuring respirators used in the workplace meet the standards of 42 CFR Part 84. Since 1994, NIOSH has maintained a searchable, online version of the Certified Equipment List.

The certified equipment list is a tool to help respirator users, safety managers, industrial hygienists, and others to:

• Determine if the respirator they are currently using or considering using is NIOSH-certified,
• Select the appropriate respirator to protect against the hazard(s) they are exposed to,
• Locate the correct replacement component parts for respirators with chemical, biological, radiological, and nuclear protections, and
• Learn what respirators are designed to provide protection from chemical, biological, radiological, and nuclear agents, and what manufacturers produce units meeting the NIOSH standards.

The Certified Equipment List is regularly updated as respirators are approved, made obsolete, or the status changes in any way.

NIOSH welcomes your feedback on the updated version. Any comments can be directed to PPEConcerns@cdc.gov.
