There has been so much activity regarding PHMSA/DOT SCBA studies, SCBA life extension, SCBA requalification, NFPA, NIOSH and other agencies that I have combined all this information into a single information source page. From the following web link you can review the most up to date information on ongoing SCBA life extension efforts and other related information:

I will be updating this page as new studies are posted by the DOT or other related composite pressure vessel news is available.
