What does 49 CFR 172.300 (Applicability) require?

Short answer

49 CFR 172.300 requires each person who offers a hazardous material for transportation to mark each package, freight container, and transport vehicle containing the hazardous material in the manner required by this subpart. Carriers that transport hazardous materials are also required to mark each package, freight container, and transport vehicle.

The rule says

"Each person who offers a hazardous material for transportation shall mark each package, freight container, and transport vehicle containing the hazardous material in the manner required by this subpart." (49 CFR 172.300(a))

"When assigned the function by this subpart, each carrier that transports a hazardous material shall mark each package, freight container, and transport vehicle containing the hazardous material in the manner required by this subpart." (49 CFR 172.300(b))

In plain English

This rule is about making sure hazardous materials are properly labeled when they're being transported. The person sending the hazardous material and the carrier transporting it both have a role in ensuring the correct markings are used. In a real-world scenario, this means that both shippers and carriers need to be aware of the specific marking requirements for the hazardous materials they're handling.

What to do

• Ensure all packages, freight containers, and transport vehicles containing hazardous materials are marked according to the requirements of 49 CFR 172.300.
• Verify that the markings include all necessary information, such as the hazard class and any relevant handling instructions.
• Train personnel on the proper marking and handling of hazardous materials to ensure compliance with the regulation.
