    I have a question to settle a debate. This pertains to air offloads, chemicals, single or multiple compartment.

    Specifically the hose that connects to the air inlet valve up top at the dome lid area. After you are all done, you've closed the valve, cleared your lines and need to go up top to check heel or depressurize the compartment so you remove the air hose connection and open the valve to depressurize.

    Now I understand before you leave the dome lid needs to be secured and the air valve in the closed position.

    My co- worker says you must reattach the air inlet hose or it's DOT violation....I personally have never had anyone tell me that. What say you? Does it matter if you are traveling and that jumper hose isn't connected? Personally I don't see how it matters

    Even if you connect air at the bottom, the valve at the dome lid always has to be closed when you are moving. If you had a rollover with the top valve open and the pipe at the bottom was damaged, product would pour from it. Even if empty the top valve should be closed.

    As far as reattaching the hose it is not a violation and I don’t know why you would want to reconnect it anyway as no product was run (or should have been run )through the hose, only air.

    I can't find any mention that the air inlet hose must be reconnected before movement in the FMCSA regulations. When people claim there is a regulation saying XYZ, IMMEDIATELY ask them to show you that regulation. Everyone has a phone and the FMCSA regulations are free and searchable anywhere with a connection or with the green & white book.

    Matlack didn't have fixed air lines on their trailers, it was part of the tractor's equipment.

    New and re-furbed trailers had caps for the air hose 'chicago' connection and sometimes missing caps would get replaced at PM's but it was always 50/50 if you actually had a trailer with a cap.

    Washbay said shop is out of them while the shop says washbay looses them....

    The company teams ran hard so the were always dropping loads and taking loads we had loaded and they didn't care about 'stuff' like that...

    I remember a Taft, LA team at the window in New Jersey saying our trailer is leaking. "

    When did you notice this?

    In Taft.....over 1000 miles leaking a toxic.........
