locked Re: Hazmat rules


From my 20 years in the fire service, DOT did away with the combustible placard in the early 1990’s or so.  Combustible covered too many commodities and shippers were using it on everything they could to avoid restrictions.  Even though it may qualify as poisonous if they could ship as combustible they would.  Emergency response also could not identify the product easily, even some shipments were “use no water” but would not be marked as such with a combustible placard.

Most diesel fuel loads from then to now are labeled Flammable.  Diesel fuel would be UN1993 in the DOT HazMat guide book.
