Q&A: Are placards necessary when transporting diesel fuel in equipment?

A question from someone I have never done business with but who found me (04.07.17):

Our company is going to be transporting in a dry van, some equipment, It runs on diesel fuel. Are DOT placards necessary if they drain the tanks before transport? or maybe only have a few gallons max in the machines? We need to know what DOT regulations have to be followed here. Like I said, it would only be a few gallons, the rest would be drained before moving.equipment with hazmat

Any help is truly appreciated

Thank you,

My reply that same day:

Thank you for contacting me.  I will do my best to answer your question below:

  • Depending on its flash point, diesel fuel is a Class 3 Combustible Liquid per USDOT regulations when transported in commerce.
  • Any amount of a hazardous material remaining in a packaging – even vapors – is subject to USDOT regulation.  There are some exceptions from full regulation for non-bulk packagings.
  • Diesel fuel is subject to the Combustible Liquid Exception which excepts it from all USDOT regulation if it is in a non-bulk packaging.
  • If the tanks on the turf-installation equipment have a capacity of no more than 119 gallons they are non-bulk packaging.
  • Diesel fuel in a non-bulk packaging is not subject to USDOT regulations, therefore the tanks do not need to be rinsed and placards are not required.  No regulations of the USDOT apply.
I hope this helps.  Please don’t hesitate to contact me with any other questions.

I get that question a lot.  For diesel fuel and other Class 3 Combustible Liquids it’s a simple matter of whether the packaging in which they are contained is bulk or non-bulk.  If non-bulk, and a few other conditions, it is not a hazardous material.  If bulk, or one of those other conditions, then it’s more complicated.
