Generated guidance. Confirm the source and its applicability before you act. How we check sources.
Short answer
Four things, and you need all of them:
1. Packages containing hazardous materials must be secured against shifting within the vehicle.
2. Packages having valves or other fittings must be loaded to minimize damage.
3. Tanks constructed and maintained in compliance with Spec. 106A or 110A must be carried in accordance with specific requirements.
4. Portable and mobile refrigeration systems must meet general packaging requirements.
The rule says
"Any package containing any hazardous material, not permanently attached to a motor vehicle, must be secured against shifting, including relative motion between packages, within the vehicle on which it is being transported, under conditions normally incident to transportation." (49 CFR 177.834(a))
"Packages having valves or other fittings must be loaded in a manner to minimize the likelihood of damage during transportation." (49 CFR 177.834(a))
"Tanks constructed and maintained in compliance with Spec. 106A or 110A (179.300, 179.301 of this subchapter) that are authorized for the shipment of hazardous materials by highway in part 173 of this subchapter must be carried in accordance with the following requirements" (49 CFR 177.834(m))
"Each non-specification pressure vessel must conform to the following: (1) Each pressure vessel must be designed, manufactured, and maintained in accordance with applicable requirements of the ASME Code (IBR, see 171.7 of this subchapter)." (49 CFR 173.5b(a))
In plain English
The rules require specific loading and carrying procedures to minimize the risk of accidents. For example, packages with valves or fittings must be loaded carefully to prevent damage, and tanks must be secured to prevent shifting. Portable and mobile refrigeration systems also have specific requirements to ensure safe transportation. These rules are in place to protect people and the environment from the risks associated with hazardous materials.
What to do
- Ensure all packages containing hazardous materials are properly secured within the vehicle.
- Load packages with valves or fittings in a way that minimizes the likelihood of damage.
- Follow specific requirements for carrying tanks constructed and maintained in compliance with Spec. 106A or 110A.
- Verify that portable and mobile refrigeration systems meet general packaging requirements.
