Do all you can to protect containers of hazardous materials. Don’t use any tools, which might damage containers or other packaging during loading. Don’t use hooks.
9.4.1 – General Loading Requirements
Before loading or unloading, set the parking brake. Make sure the vehicle will not move.
Many products become more hazardous when exposed to heat. Load hazardous materials away from heat sources.
Watch for signs of leaking or damaged containers: LEAKS SPELL TROUBLE! Do not transport leaking packages. Depending on the material, you, your truck, and others could be in danger. It is illegal to move a vehicle with leaking hazardous materials.
Containers of hazardous materials must be braced to prevent movement of the packages during transportation.
No Smoking. When loading or unloading hazardous materials, keep fire away. Don’t let people smoke nearby. Never smoke around:
Secure Against Movement. Brace containers so they will not fall, slide, or bounce around during transportation. Be very careful when loading containers that have valves or other fittings. All hazardous materials packages must be secured during transportation.
After loading, do not open any package during your trip. Never transfer hazardous materials from one package to another while in transit. You may empty a cargo tank, but do not empty any other package while it is on the vehicle.
Cargo Heater Rules. There are special cargo heater rules for loading:
The rules usually forbid use of cargo heaters, including automatic cargo heater/air conditioner units. Unless you have read all the related rules, don’t load the above products in a cargo space that has a heater.
Use Closed Cargo Space. You cannot have overhang or tailgate loads of:
You must load these hazardous materials into a closed cargo space unless all packages are:
Precautions for Specific Hazards
Class 1 (Explosives) Materials. Turn your engine off before loading or unloading any explosives. Then check the cargo space. You must:
Use extra care to protect explosives. Never use hooks or other metal tools. Never drop, throw, or roll packages. Protect explosive packages from other cargo that might cause damage.
Do not transfer a Division 1.1, 1.2, or 1.3 from one vehicle to another on a public roadway except in an emergency. If safety requires an emergency transfer, set out red warning reflectors, flags, or electric lanterns. You must warn others on the road.
Never transport damaged packages of explosives. Do not take a package that shows any dampness or oily stain.
Do not transport Division 1.1 or 1.2 in vehicle combinations if:
Class 4 (Flammable Solids) and Class 5 (Oxidizers) Materials. Class 4 materials are solids that react (including fire and explosion) to water, heat, and air or even react spontaneously.
Class 4 and 5 materials must be completely enclosed in a vehicle or covered securely. Class 4 and 5 materials, which become unstable and dangerous when wet, must be kept dry while in transit and during loading and unloading. Materials that are subject to spontaneous combustion or heating must be in vehicles with sufficient ventilation.
Class 8 (Corrosive) Materials. If loading by hand, load breakable containers of corrosive liquid one by one. Keep them right side up. Do not drop or roll the containers. Load them onto an even floor surface. Stack carboys only if the lower tiers can bear the weight of the upper tiers safely.
Do not load nitric acid above any other product.
Load charged storage batteries so their liquid won’t spill. Keep them right side up. Make sure other cargo won’t fall against or short circuit them.
Never load corrosive liquids next to or above:
Never load corrosive liquids with:
Class 2 (Compressed Gases) Including Cryogenic Liquids. If your vehicle doesn’t have racks to hold cylinders, the cargo space floor must be flat. The cylinders must be:
Cylinders may be loaded in a horizontal position (lying down) if it is designed so the relief valve is in the vapor space.
Division 2.3 (Poisonous Gas) or Division 6.1 (Poisonous) Materials. Never transport these materials in containers with interconnections. Never load a package labeled POISON or POISON INHALATION HAZARD in the driver’s cab or sleeper or with food material for human or animal consumption. There are special rules for loading and unloading Class 2 materials in cargo tanks. You must have special training to do this.
Class 7 (Radioactive) Materials. Some packages of Class 7 (Radioactive) materials bear a number called the “transport index.” The shipper labels these packages Radioactive II or Radioactive III, and prints the package’s transport index on the label. Radiation surrounds each package, passing through all nearby packages. To deal with this problem, the number of packages you can load together is controlled. Their closeness to people, animals, and unexposed film is also controlled. The transport index tells the degree of control needed during transportation. The total transport index of all packages in a single vehicle must not exceed 50.Table A to this section shows rules for each transport index. It shows how close you can load Class 7 (Radioactive) materials to people, animals, or film. For example, you can’t leave a package with a transport index of 1.1 within two feet of people or cargo space walls.
Mixed loads. The rules require some products to be loaded separately. You cannot load them together in the same cargo space. Figure 9.9 lists some examples. The regulations (the Segregation Table for Hazardous Materials) name other materials you must keep apart.
Regulations in red are new this year.
