Publication NFPA 58 covers the requirements for propane storage and
transport equipment. Any gas handling facility should have one in their
possession. The NFPA list of books cover a lot of controlled subjects, and
are what Authorities Having Juristiction (AHJ) refer to as their enforcement
criteria. In North Carolina, LP is regulated by the Dept of Agriculture,
Standards division, just for reference. As part of my job, I monitor,
maintain, and control operations of an 18,000 gallon bulk isobutane storage
facility that fills small disposable cyinders. You would not believe the
rules and laws controlling the facility.

Toller, you don't value your life much do you?

Discarded tanks may not pass a hydro test. Refrigerant recovery tanks
must get hydrostatically tested every 5 years to be legal. If those
discarded tanks won't pass the test they are not safe to use. You
might get away with it, but why take the chance? I am not talking
about the law either.

He said they were discarded, not past date for testing.

New tanks have OPD valves and some places will no longer fill them. Some
states have adopted the new regs, some have not. I still use my old tanks
and will as long as legal to do so. IIRC., propane tanks are 10 or 12
years.
