Respiratory protection is addressed in specific OSHA standards for general industry, maritime, and construction. This section highlights OSHA standards and documents related to respiratory protection. OSHA’s revised Respiratory Protection Standard (29 CFR 1910.134 and 29 CFR 1926.103) went into effect April 8, 1998. The final standard replaces the respiratory protection standards adopted by OSHA in 1971. The 29 CFR 1910.139 respirator standard that applied only to respiratory protection against Mycobacterium Tuberculosis was withdrawn December 31, 2003. Establishments whose respiratory protection programs for tuberculosis formerly covered under 29 CFR 1910.139 were required to adapt their programs to comply with the requirements of 29 CFR 1910.134 effective July 2, 2004.
