Chemical, Biological, Radiological and Nuclear (CBRN) Combination Respirator Unit (CRU)

The National Institute for Occupational Safety and Health (NIOSH) is working to develop appropriate standards and test procedures for the various types of respiratory protective devices used to provide protection to workers in hazardous environments. NIOSH has initiated a program to update portions of Title 42 Code of Federal Regulations Part 84 (42 CFR Part 84) to promote improved performance and reliability of the various types of respiratory protective devices.

This effort focuses on the development of an appropriate performance standard for the combination respirator unit (CRU) that will provide wearers respiratory protection against Chemical, Biological, Radiological and Nuclear (CBRN) hazards resulting from acts of terrorism.

The CRU is a multifunctional unit that employs the technology of two or more different types of respiratory protective devices.

This subject was discussed at a NIOSH sponsored public meeting that was held on December 9, 2010 at the Hyatt Regency Pittsburgh International Airport.
