What changed

This document is a CFR Correction issued by the Research and Special Programs Administration (RSPA) of the Department of Transportation. It amends Title 49 of the Code of Federal Regulations, specifically § 173.315 concerning compressed gases in cargo tanks and portable tanks. The correction adds paragraph (i)(8), requiring that each pressure relief valve outlet must have a protective device to prevent dirt and water accumulation without impeding flow, and that pressure relief devices must be designed to prevent foreign matter entry, liquid leakage, and dangerous excess pressure development.

This is a minor technical correction to existing regulations. While it does not introduce new compliance obligations beyond ensuring existing pressure relief valves meet the specified protective device requirements, it clarifies existing standards for the safe transport of compressed gases. Regulated entities involved in shipping compressed gases in cargo tanks and portable tanks should ensure their equipment complies with this clarified requirement.

What to do next

Review § 173.315(i)(8) for requirements on pressure relief valve outlets for compressed gas shipments.
Ensure pressure relief valve outlets are equipped with protective devices that prevent dirt and water entry without impeding flow.
