Familiar with CFR? Placarding 1203 for a full load of 1993?

1203 is gasoline and 1993 is the generic placard for Flammable, each hazard class has a 'generic' number; 1993 is Flammable Liquid NOS [not otherwise specified] and with the US drifting slowly into international compliance.

Diesel used to be a 'combustible', a US term for liquids with a flashpoint of 101 degrees to 200 degrees [class 3 had decimals according to the flash point where gas was 3.1 and combustibles were 3.3; the rest of the world did not make this distinction so the US changed, little by little] and Flammable was reserved for products with a flash point under 100 degrees.

Looking now in 172.101 tables, I see that Diesel fuel does not have a specific number and Fuel oil [#1,#2.ETC.] is all placarded 1993

 

When hauling diesel, I keep a single compartment with gas tails (the little bit that won't drain completely) so I'm legal to placard 1203.
That said, when I have every compartment loaded with diesel, I placard 1993.
That's per my bol instructions for that product.
In speaking with a rack manager, there's little difference between diesel, kerosene, and heating oil, from a chemical standpoint,and are pretty much treated the same for transport purposes.
But what do I know... I'm just a dumb truck driver.

 

I think the "placard for lowest flashpoint" is a work procedure or "best practice" procedure and not a matter of regulation. Drivers have to do more than JUST comply with a regulation. I never pulled fuels, just acids.

We do our best to follow the rules... Doing what we do, we gotta play it as safely as possible.
Lord knows it's crazy enough out there...
Stay safe

 

Yep , thats what i do too.
FYI - the last item hauled bol should be in the door and your current load bol should be with in your reach. ( so .... you should be placarded with what you got.
If your empty , and going back for another one , then you should be placarded with what you did have on.)
