What is the required retest method for halocarbon storage containers?

• A. A full hydrostatic test
• B. A complete visual inspection as described in 49 CFR
• C. A weight-check only
• D. A leak test with inert gas

Answer: (B)

For halocarbon storage containers, the retest is a complete visual inspection as described in 49 CFR. This requirement focuses on checking the container’s exterior condition, including for dents, corrosion, deformation, neck ring and valve condition, labeling, and overall physical integrity. The idea is to verify there are no obvious defects or damage that could compromise safety before the container is recharged or put back into service.

A full hydrostatic test, while important for certain cylinders at specified intervals, is not the mandated retest method in this context. A weight-check alone would not reveal hidden damage or leaks, and a leak test with inert gas, while useful for detecting leaks, does not replace the comprehensive visual inspection mandated by 49 CFR for this application.
