High Pressure Cylinders Improperly-Marked with ''A978'' or Month and Year.
PHMSA warns against filling improperly-marked high pressure cylinders with hazardous materials. These cylinders may rupture under pressure during normal transportation and use, potentially resulting in extensive property damage, serious personal injury, or death.
3/13/2013—PHMSA has become aware of approximately 496 improperly-marked DOT 3AA and 3AL cylinders used in carbon dioxide service. Kraus Fire Equipment Co. marked cylinders provided by Flint Welding Supply Co. with a requalification identification number (RIN) without first performing a valid hydrostatic requalification test, which is required under the Hazardous Materials Regulations.
Characteristics of the Unauthorized Cylinders:
1. Purchased or serviced from Flint Welding Supply Company around June 2010 to December 2012.
2. Cylinders are improperly-marked with either "A978", full or partially, or just the month and year, without a requalification identification number (RIN) mark in the middle.
These cylinders should be considered unsafe and unauthorized for filling with hazmat, unless and until they are properly tested by an individual or company that is authorized by DOT to requalify DOT specification cylinders.
Companies and Individuals with Improperly-Marked Cylinders: If you are in possession of cylinders identified in this advisory and they are filled with an atmospheric gas, please arrange for authorized personnel to vent or otherwise safely discharge the contents. Individuals are advised to remove it from service and return it to Flint Welding Supply Co, Flint MI.
