Receiving and Identification of Cylinders

Before a receiving department accepts a cylinder of gas, the contents must first be identified. The gas name may be stenciled on the cylinder or shown on a label or decal that is attached to the cylinder body. An identification tag may be attached to the cylinder valve and/or to the valve protection cap, and these tags may also contain safety precautions. 

The DOT label is diamond shaped and supplies the user with only the chief hazards associated with the gas. The degree of hazard is not readily indicated. Many gas suppliers provide more detailed information on the hazards associated with the gas they distribute. Also, most suppliers send a MSDS (Material Safety Data Sheet) to each customer who receives a gas cylinder. This MSDS should be on file at facility where the gas is being used and be available for reference by all employees when detailed information on properties and hazards is needed. 

If the cylinder has undergone international transport, it should be marked in accordance with rules set forth by the International Standards Organization. If the cylinder has been shipped from overseas, then it will be labeled following rules established by the Intergovernmental Maritime Consultive Organization (IMCO).
