PHMSA letter of interpretation

Training for repairers

Pipeline and Hazardous Materials Safety Administration · Sep 27, 2007 · Reference No. 07-0137

Interprets: 49 CFR § 171.8

Reggie’s quick take

Someone asked whether employees who maintain and repair freight containers, reefer containers, flat racks and chassis owned or leased by their ocean carrier count as hazmat employees under the HMR. The agency's answer is no, unless that equipment includes packages, containers or packaging components that are represented, marked, certified or sold as qualified for transporting hazardous material. The agency cites § 171.8 for this definition.

Written by AI (Claude) on Oct 22, 2026. Robots make mistakes and leave things out, so the letter below is what counts. Not legal advice.

This is in response to your letter dated July 3, 2007 concerning the definition of hazmat employee under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if employees who maintain and repair freight containers, reefer containers, flat racks, and chassis that are owned and/or leased by your ocean carrier company meet the definition of a hazmat employee under the HMR. You state that the employees in question do not load, unload, classify, mark, label, placard, transport or accept hazardous materials.

A hazmat employee, as defined in § 171.8, includes a person who designs, manufactures, fabricates, inspects, marks, maintains, reconditions, repairs, or tests a package, container or packaging component that is represented, marked, certified, or sold as qualified for use in transporting hazardous material in commerce. Based on the information you provided, the employees in question do not meet the definition of a hazmat employee unless the equipment that these employees maintain and repair includes packages, containers, or packaging components that are represented, marked, certified, or sold as qualified for use in transporting hazardous material in commerce.

A letter of interpretation applies the regulations to the facts the requester described. It isn’t a regulation and isn’t legal advice. The agency’s copy.
