PHMSA releases cargo tank safety advisory, drug testing rate

The Pipeline and Hazardous Materials Safety Administration on March 3 released a safety advisory (.pdf file) reminding manufacturers or users of composite cargo tank motor vehicles to test tank and material compatibility.

The advisory is directed at people authorized under Department of Transportation special permits to ensure materials for transport in the cargo tank are compatible with the materials used in the construction of the cargo tank. It was prompted by a December 2009 incident in which a composite tank failed catastrophically while carrying incompatible materials and released its contents onto a highway.

In other news, PHMSA published a notice (.pdf file) in the Feb. 26 Federal Register announcing the minimum random drug testing rate for covered employees will remain at 25 percent during calendar year 2010.
