Safety Advisory: Unauthorized Stamping of DOT specification Compressed Gas Cylinders

This is to notify the public that RSPA has documented the unauthorized stamping of indentations in the side walls of high- pressure compressed gas cylinders by Blue Water Divers (Blue Water), Ltd., Road Town, Tortola, British Virgin Islands. The cylinders are being used in the SCUBA industry. An undetermined number of the SCUBA cylinders or "dive tanks" owned by Blue Water Divers were stamped with month and year markings in the side walls of the cylinders. RSPA has determined that some of the cylinders may have been sold to individuals or U.S. companies and possibly are being used for transportation of hazardous materials in commerce in the U.S. All cylinders observed were DOT 3AL aluminum cylinders, but other cylinder types may be involved. The Hazardous Materials Regulations (HMR) specifically prohibit stamping in the side wall of compressed gas cylinders, except DOT 3E cylinders, because doing so could compromise the structural integrity of the cylinder. The HMR prohibit the charging or filling of DOT specification or exemption cylinders with compressed gas or other hazardous materials and the offering for transportation of cylinders with markings stamped in the side walls.
