Most dangerous

Probably nitric acid. Though I've had a few poison loads, but I'm not sure exactly how poisonous they were.

 

44,000 lb of Phosphorous, the kind you use on tracer rounds from Indiana to Port Chicago CA. 1 box of exactly 1 quart of Nitro Glycerine on a Reefer, had to be kept at 20 degrees from Hawthorne CA to Yuma AZ. It was suspended on springs in the middle of the trailer and markd HIGHLY EXPLOSIVE. 500 lb bombs, 18-20 ft missles, Class A Explosive we took from Alameda to WA state and they loaded them in a Sub and it left before we could throw our chains. Said they did'nt want the Russian knowing where they were.

 

No on a flatbed. In fact my picture is hear on the net. Search for Navy Nuclear Weapons assoc. and find the people page and that's me standing in front of a gasoline powered semi when I was 17. Wow so many years ago.

 

I drove team for TSMT in 1968-69. One load from Hanford Works, WA to Paducah, KY consisted of leather sacks of explosive suspended by coil springs in drums of antifreeze. The consignee inspected each drum to make sure the sacks were still suspended before they allowed us in the gate.

I hauled molten aluminum in crucibles at 1600 degrees. During unloading at casting plants, I wore a leather welder's jacket, chaps and spats.

I hauled caustic phosphate in tankers. The BL required a rubber suit during unloading with an emergency shower or running water hose nearby.

I also hauled dynamite to construction sites and fingerprinted the loads into oak-lined Quonset huts. The only hazard there was the headache you get from dynamite fumes.

 

Sodium cyanide and crude are all I've ever hauled in a tanker that was dangerous.
On a flatbed, I guess, Enriched Uranium and more cyanide.
