How often hazmat cylinders, cargo tanks, IBCs and portable tanks must be retested

Mandatory requalification, retest and inspection intervals for pressure containers under 49 CFR Part 180, with the qualifier that decides which interval applies. Each record is one container specification under one test type, stating the interval in years and the condition attached to it. Covers cylinders (49 CFR 180.209), cargo tanks (180.407), intermediate bulk containers (180.352) and portable tanks (180.605). Answers 'how often does a scuba tank need hydro testing', 'DOT 3AL requalification 5 years or 12', 'IBC tote retest interval 2.5 years', 'MC-331 propane cargo tank internal visual inspection frequency', and 'when does a DOT 3AA cylinder qualify for the 10 year star'. The interval is a property of the specification, the service and the configuration together, not of the container alone, and the exceptions are where the answers go wrong: DOT 3AL is 5 or 12 years depending on service, and an MC-331 under 3,500 gallons in dedicated propane service built from non-quenched-and-tempered SA-612 gets 10 years where every other cargo tank gets 5. Past the due date the container may not be filled and offered for transportation.
Provenance — what every record carries
Every record carries source (the URL the value was read from) and
source_quote (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its url.
Licence position
Facts extracted from the US Code of Federal Regulations, a US government work not subject to copyright. Text is read via law.cornell.edu because eCFR blocks our fetcher; the fact is the regulation's, not Cornell's, and each record quotes a short verbatim span and links back to the section.
Facts are not copyrightable; what this dataset takes from each source is a fact plus a short attributed quote linking back to the page that states it.
