Hazmat placarding for 2 attached trailers

I have to circle back for my own updating knowledge out of curiousity. Does the old Class A placards remain in effect? Both of them with a 1 under would cover that rig nicely back in my time.

 

Phone DOT see if they can email you info. I regularly carried 1.1B in cap box in trailer loaded with 1.1D and trailer would be placarded 1.1D.
We hauled either in truck or tractor trailer. Your configuration of truck trailer was not allowed at that time in Canada or we would have jumped at the opportunity. Our cap box was limited to about 15 cases if we had powder on.
The 1.1D is mass explosive which could be many products, the 1.4S is some type of ammunition

 

Look at it this way, if you wreck and #### goes to hell are both materials going to act the same? Will they explode, implode, relaease gases etc. I didnt look at 1.1 and 1.4. I assume ammunition and explosives.
Back to the point though, if its placarded 1.1D as the worse hazard... but 1.4 responds to fire differently....

The point of placards is to let emergency personnel know what your hauling and how to deal with it. The palcards are specific sizes because you can glass them from safety at hundreds of yards and know whats in the trailer.
If you cant find the regulation or what you think should be a regulation in the hazmat regulation book, then placard both units according to their specific cargo. The regulation i think you are looking for applies to two seperate cargos in the same trailer.

Two cargos in two trailers is completely different.

 

Im disappointed to hear that your Company is not helpful. That is not good. I appreciate your communicating. Im pretty firm with the seperate placarding.

Another poster beat me to the idea of calling DOT, there has to be some communication.

Another idea.... I am sort of real BAAAD at creating a workaround in life... is to have two drivers, two tractors, one trailer each and BOOM. Legal. No ifs buts conflicts or confusion. Does that make sense? It might cost a little more to everyone. But not anywhere as much as enforcement action and fines.

 

You do realize this is a military vehicle? Not a contractor but vehicle with gun on top in war. Goes pew pew....

It is sad that the ammo dump doesnt tell you how to placard it, they should know. They at least knew in japan and cali for us.

 

This is a LMTV with a trailer. Same set up the op will use. The trailer will have a cargo cover like the main unit though.

 

The 1.4s does not need any placcards. It is ammo. The 1.1 is a different matter, but then the military is probably not held to dot standards.

 

Ammo needs 5 miles radius and line of sight evacuation according to Hazmat guide for fire and other related trouble. If the Artillery, tank rounds etc are big enough you might need to clear 10 miles radius.

Small arms is either ORM-D for the likes of fed ex home delivery (They use a dedicated marked and placarded home delivery truck in my area just for distributing ammo, when I buy regularly) Or 1.4 under the Hazmat. Fire fighting and other trouble pathways to resolving problems with small arms are different than 1.1.

Ive said enough. Im not trying to conflict or cause trouble. I consider class A explosives dead serious and if it needs a thousand placards covering the whole rig (To paraphrase) that is what it will get.
