Tennessee CDL DMV Endorsement Hazmat 2

A person should not smoke within 25 feet of a placarded tank that is used to transport Class 3 (flammable liquids) or Division 2.1 (gases) materials. Additionally, no person should smoke or carry a lit cigar, cigarette, or pipe within 25 feet of any vehicle containing Class 1 (explosives), Class 4 (flammable solids), or Class 4.2 (spontaneously combustible).

If you are experiencing a truck fire, you should not attempt to open trailer doors without first feeling the doors to see if they are hot. If the doors are hot, there may be a cargo fire. In this case, leave the doors closed because opening the doors could worsen the fire by supplying it with more oxygen.

Many products classed as poison are also flammable. Take the appropriate precautions if you think your cargo may be flammable.

When transporting hazardous materials, you may leave your vehicle unattended in a safe haven. A safe haven is a location that has been approved for parking unattended vehicles that are loaded with explosives.

One clue that a shipment may contain hazardous materials is that the shipper is in a line of business that you would expect to involve hazardous materials. Examples of such businesses include paint dealers, chemical suppliers, scientific supply houses, pest control companies, agricultural suppliers, and dealers in explosives, fireworks, or munitions.

When transporting hazardous materials, you may leave your vehicle unattended in a safe haven. A safe haven is a location that has been approved for parking unattended vehicles that are loaded with explosives.

A hazardous material will fall into one of nine hazard classes. The material's hazard class reflects its associated risks.

Flammable gases are assigned to hazardous materials Class 2.

If your vehicle breaks down on the road while you are transporting explosive materials, you must warn other drivers. Put out warning signals like reflective triangles or electric lights if you are carrying Division 1.1, 1.2, or 1.3 explosives. Do the same if you are driving a tank used to transport Class 3 flammable liquids or Division 2.1 flammable gases, even if the tank is empty. If transporting flammable materials, do not use warning signals that could cause your cargo to catch fire.

When carrying hazardous materials, it is a good idea to compare the shipping papers to the markings and labels on the packages.

For all shipments of hazardous materials, the shipper must use shipping papers to inform drivers and dockworkers of the risks presented by the cargo.

Unless excepted, hazardous materials shipping papers must list an emergency response telephone number.

Keep liquid discharge valves on a compressed gas tank closed except when loading and unloading.

If a shipping paper lists both hazardous and non-hazardous materials, the hazardous materials must be entered first.

You must examine each tire on a motor vehicle at the beginning of each trip. The only effective way to check tire pressure is by using a tire pressure gauge.

A shipping paper describes the hazardous materials being transported. Shipping orders, bills of lading, and manifests are all shipping papers.

If the letter “G,” for "Generic," is written in Column 1 of a shipping paper, the technical name of the associated hazardous material must also be listed.

A person attending a placarded vehicle must be awake inside the vehicle or otherwise within 100 feet of the vehicle; know the hazards associated with the materials; know what to do in an emergency; and be able and authorized to move the tank if necessary.

On a compressed gas tank, liquid discharge valves must always be kept closed, except during loading and unloading.

At a minimum, emergency response information must include the basic descriptions and technical names of the materials being transported; immediate hazards to health; risks of fire or explosion; immediate precautions to be taken in the event of an accident or incident; immediate methods for handling fires; initial methods for handling spills or leaks in the absence of fires; and preliminary first aid measures.

You must examine each tire on a motor vehicle at the beginning of each trip. The only effective way to check tire pressure is by using a tire pressure gauge.

The loading of a tank with hazardous materials must always be watched by a qualified person. This person must be alert; have a clear view of the tank; stay within 25 feet of the tank; know the hazards associated with the materials; know what to do in an emergency; and be able and authorized to move the tank if necessary.

Some radioactive materials are required to be accompanied by a transport index. A transport index is a number that indicates how much control the material will require during transport. The total transport index of all cargo in a single vehicle may not exceed 50.

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.

Shippers must place diamond-shaped hazard warning labels on most packages of hazardous materials. If the label won't fit on the package, it can be placed on a tag that is securely attached to the package.

A Uniform Hazardous Waste Manifest must be signed by hand. The name and EPA registration number of the shippers, carriers, and destination must also appear on the manifest.

The shipper of hazardous materials is responsible for packaging, marking, and labeling the materials properly. It is a good idea for the driver to ensure the materials are properly labeled.

Cylinders and drums are often used to contain hazardous materials. Be sure to take the proper precautions if transporting a cargo of hazardous materials.

Among other information, shipping papers must include a description of the specific hazardous materials being transported.

A vehicle must be properly placarded before it can be driven. A vehicle that does not display the proper placards may not be moved unless doing so is necessary to protect life or property in an emergency.
