Safety Advisory: Unauthorized Marking of Compressed Gas Cylinders

Safety advisory notice.

This is to notify the public that RSPA is investigating the possible unauthorized marking of high-pressure compressed gas cylinders by ABM Fire Equipment, 73 North Main Street, Milford, NY 13807. RSPA has evidence that suggests ABM Fire Equipment marked, certified and returned to service an undetermined number of high-pressure DOT specification and exemption cylinders as being properly requalified in accordance with the Hazardous Materials Regulations (HMR), when the cylinders may not have been hydrostatically retested and visually inspected. A hydrostatic retest and visual inspection, conducted as prescribed in the HMR, are used to verify the structural integrity of a cylinder. If the hydrostatic retest and visual inspection are not performed in accordance with the HMR, a cylinder with compromised structural integrity may be returned to service when it should be condemned. Extensive property damage, serious personal injury, or death could result from rupture of a cylinder. Cylinders that have not been requalified in accordance with the HMR may not be charged or filled with compressed gas or other hazardous material and offered for transportation in commerce.
