We often get this question during audits and PHAs, as it seems to be “common practice” for the driver to reside inside their cab doing paperwork while they are the intended “hazmat attendant”.

I have seen a cost savings trend that is increasing risks in a big way. It may seem minor to those who do not understand risk, but using a pressure cylinder without it being inspected and tested at its prescribed frequency is a serious safety miss.

I took some flak for stating that I have seen overfilling of LPG cylinders…...
