Shipping papers must be quickly accessible in the event of an emergency.

Shipping papers may be kept on the driver’s seat when the driver is out of the vehicle.

If the words "Inhalation Hazard" appear on the shipping paper or package, you must display the "Poison Inhalation Hazard" or "Poison Gas" placards, as appropriate.

All drivers must be trained in the security risks of hazardous materials transportation. This training must include how to recognize and respond to possible security threats. Hazardous materials employees must be trained and tested at least once every three years.

The power unit of a placarded vehicle must be equipped with a fire extinguisher with an Underwriters Laboratories (UL) rating of 10 B:C or more.

Hazardous materials warning placards are usually diamond-shaped.

The marine pollutant symbol is the image of a fish in a white triangle with an X through through the fish.

A vehicle that has not been properly placarded may not be driven, except when necessary to protect life or property in an emergency.

Unless you must run the engine to operate a pump, you should always turn off the engine before loading or unloading flammable liquids.

Shippers of certain kinds of hazardous materials are required to display diamond-shaped warning signs, known as placards, on any transporting vehicles. Shippers are required to provide applicable placards, labels, shipping papers, and emergency response information.

Shippers package hazardous materials in a way that is meant to completely contain the materials. Vehicles should be placarded to communicate the risk of the cargo.

When carrying Division 1.1, 1.2, or 1.3 explosives, do not park within 300 feet of a bridge, tunnel, or building; a place where people gather; or an open fire.

You must have a CDL with a hazardous materials endorsement to operate a vehicle of any size that is used to transport hazardous materials.

Containers of hazardous materials should be braced so they will not fall, slide, or bounce around during transportation.

Many hazardous materials classified as poisonous are also flammable.

The shipper of hazardous materials is responsible for packaging, marking, and labeling the materials. They must supply the warning placards.

When a shipper packages hazardous materials, they certify that the package has been prepared according to Hazardous Materials Regulations (HMR). Unless a package is clearly unsafe or noncomplying with HMR, you may accept the shipper’s certification concerning the proper packaging of a material.

When experiencing a cargo fire, it may be a bad idea to open the doors to the trailer. Doing so allows oxygen to enter the area, potentially causing the fire to flare up and expand.

Fighting a hazardous materials fire requires specialized training and equipment. Unless you possess these yourself, it is best to let emergency personnel deal with the fire.

When transporting hazardous materials, shipping papers should be kept in a pouch in the driver's side door, or in another location where the driver is able to easily reach them while their seat belt is fastened. The papers must be easily visible to anyone who is entering the cab.

If you are involved in an accident while carrying hazardous materials, it is your responsibility as the driver to keep people away from the scene; limit the spread of material if you can safely do so; inform emergency response personnel of the dangers posed by the materials; and provide emergency personnel with the shipping papers and emergency response information. Unless you have protective equipment and the necessary training, do not try to fight hazardous materials fires yourself.

The use of cargo heaters is not always permitted. When transporting materials that are categorized as Class 1 (Explosives), Class 2.1 (Flammable Gases), or Class 3 (Flammable Liquids), the use of heaters in the same space is generally prohibited.

Except when parking briefly to perform necessary functions for vehicle operation (such as refueling), never park a vehicle carrying Division 1.1, 1.2, or 1.3 explosives within 300 feet of a bridge, tunnel, or building. Never park such a vehicle within five feet of the traveled portion of the road.

You should never transport damaged packages of explosives. Do not accept a package that seems damp or has an oily stain.
