Cylinder Failure Analysis Reports
These files are documents frequently requested pursuant to the Freedom of Information Act (FOIA). The majority of documents requested under FOIA from the PHMSA Office of Hazardous Materials Safety are generated as the result of a hazardous materials accident or incident. Documents that have been released to an initial requester are then classified as public information and are not subject to FOIA.
The following files are Metallurgical Evaluation / Analysis Reports performed on Ruptured DOT-3-AL Aluminum Cylinders in the United States in order to determine the cause of the failure and its relevant to sustain load cracking. If you have any technical question (only) please contact Mr. Mark Toughiry, 202-366-4545.
