What does 49 CFR 180.407 (Requirements for test and inspection of specification cargo tanks) require?

Short answer

The requirements for test and inspection of specification cargo tanks under 49 CFR 180.407 include:

1. A cargo tank must be tested and inspected prior to further use if it shows evidence of dents, cuts, gouges, corroded or abraded areas, leakage, or any other condition that might render it unsafe for hazardous materials service.

2. A cargo tank must be pressure tested if it has sustained damage to an extent that may adversely affect its lading retention capability.

3. A cargo tank that has been out of hazardous materials transportation service for a period of one year or more must be pressure tested prior to further use.

The rule says

"A cargo tank constructed in accordance with a DOT specification for which a test or inspection specified in this section has become due, may not be filled and offered for transportation or transported until the test or inspection has been successfully completed." (49 CFR 180.407(a)(1))

"The cargo tank shows evidence of dents, cuts, gouges, corroded or abraded areas, leakage, or any other condition that might render it unsafe for hazardous materials service." (49 CFR 180.407(b)(1))

"The cargo tank has sustained damage to an extent that may adversely affect its lading retention capability." (49 CFR 180.407(b)(2))

"The cargo tank has been out of hazardous materials transportation service for a period of one year or more." (49 CFR 180.407(b)(3))

In plain English

These requirements are in place to ensure that cargo tanks are safe for transporting hazardous materials. If a cargo tank is damaged or has been out of service for an extended period, it must be thoroughly inspected and tested before it can be used again. This includes checking for any signs of damage, corrosion, or leakage, and performing pressure tests to ensure the tank can withstand the stresses of transportation. The goal is to prevent accidents and protect people and the environment from the risks associated with hazardous materials.

What to do

• Regularly inspect cargo tanks for signs of damage or wear.
• Perform pressure tests on cargo tanks that have been damaged or out of service for an extended period.
• Keep records of all inspections and tests performed on cargo tanks.
• Ensure that all cargo tanks are properly maintained and repaired to prevent damage and ensure safe transportation of hazardous materials.
