Texas CDL DMV Endorsement Hazmat 2

The third column of the Hazardous Materials Table lists items' hazard classes and divisions. Drivers should never transport a material that is marked by the word "Forbidden."

Identification numbers, shipping names, and hazard classes must never be abbreviated when listed on a shipping paper. The only exception to this is if the abbreviation is specifically authorized in the hazardous materials regulations.

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 vehicle carrying hazardous materials must be appropriately placarded to be driven. An improperly placarded vehicle may only be driven if necessary to protect life or property in an emergency.

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.

If you discover a leak in a cargo of hazardous materials, identify the materials in question by using the shipping papers, labels, or package location. Do not touch the leaking material.

Use a floor lining when transporting Division 1.1, 1.2, or 1.3 materials. The floors should be tight and the liner must be made from either non-metallic material or non-ferrous metal. Non-ferrous metals are metals that do not contain iron or iron alloys.

Radiation will surround each package of radioactive materials and pass through to all nearby packages. The number of packages that can be loaded together is controlled.

When the 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.

There are nine different classes of hazardous materials. A class reflects the risks associated with a type of material.

Signs are placed on the outside of vehicles and bulk packages to warn drivers and others about hazardous materials. These diamond-shaped signs are known as "placards."

Because of the risks presented by the nature of the materials, government on federal, state, and local levels may impose regulations on the transportation of hazardous materials.

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.

A material's ID number must appear on its accompanying shipping paper as well as on its packaging. It must also appear on cargo tanks and other bulk packaging.

When hazardous materials placards are required, they must be placed on all four sides of the transporting vehicle.

Parts of a vehicle that have been exposed to a corrosive material must be thoroughly washed with water.

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 a road. Such vehicles should be parked only briefly.

When loading hazardous materials, do not use hooks or tools that could damage containers or other packaging.

The employer of a driver who will transport hazardous materials, or the employer's designated representative, is required to provide the driver with applicable training and testing.

If you are driving a vehicle that is transporting Class 1 explosives and it is involved in an accident, you should warn others of the danger, keep bystanders away, and not allow smoking or open fires near the vehicle. Before separating the vehicles involved in the collision, remove all explosives and place them at least 200 feet away from the vehicles and any occupied buildings.

If a package of hazardous materials is not large enough to display the proper label, the label may be placed on a tag that is securely attached to the package.

While the manual contains all of the information needed to pass the written exam for a hazardous materials endorsement, it does not contain all of the information necessary to do the job safely. You can learn more by attending hazardous materials training courses.

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 supply businesses, or pest control firms.

Always turn off your vehicle's engine before loading or unloading explosive materials. Never drop, throw, or roll packages containing explosives.

When a shipper packages hazardous materials, they are certifying that the package has been prepared in accordance with its applicable rules.

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.

You should examine your tires at the beginning of every trip and after every stop to ensure that they are properly inflated. The only acceptable way to check tire pressure is to use a tire pressure gauge.

Flammable liquids should not be transferred from one vehicle to another on a public roadway, unless being moved due to an emergency. Always warn others of the hazards presented by the materials.

Hazardous materials are products that pose risks to health, safety, and property during transportation. Materials that are considered hazardous include explosives; flammable and poisonous gases; and flammable and other hazardous solids.

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