We see them every day. Big trucks carrying haz mat passing us on the highways. Each is required to have 4 placards (one facing each direction) on the trailer. Well the one on the front of the trailer can in some instances be on the front of the tractor. But what do they mean? Each placard will have a small number in the bottom corner and a large number in the middle. Some won't have the large number in the middle though.
If the placard is orange that means explosives. A red one means flammable. Yellow is oxidizers. White with vertical red stripes means flammable solids. White means poison. White on top black on bottom indicates corrosive. There are of course variations of this but basically that is what you will be seeing out there on the road. In the middle of some placards and in other cases under the placard will be a 4 digit black number on an orange background indicates the actual material being hauled. Below I have listed some of the most common you will see along with some interesting or sphincter tightening ones that you hope never pass you.

1028 R12 Refrigerent
1018 R22 Refrigerant

And of course if 1013 is in liquid form the number will be different because of different hazards associated with the transport of it. If you see any out there and are curious email em to me and I will tell you what you passed or what passed you. Or get your own copy of the Emergency Response Guidebook availible in most truck stops.

I want to know all the things that was part of a heavy hauling job so that I know where will I be. It is not easy to work in a heavy hauling company if you don't have a knowledge about it.
