HAZARD:
There is a reoccurrence of Oxygen and Acetylene cylinders not stored properly in our warehouse facilities. This is a fire and explosion hazard.
When not in use, Cylinders must be separated a minimum distance of 20 feet or by a noncombustible barrier at least 5 feet high having a fire-resistance rating of at least one-half hour. Cylinders must not be placed where they might become part of an electric circuit. Cylinders must be kept away from radiators, piping systems, layout tables, etc., that may be used for grounding electric circuits such as for arc welding machines. Any practice such as the tapping of an electrode against a cylinder to strike an arc is prohibited.
Oxygen cylinders will not be stored near highly combustible material, especially oil and grease; or near acetylene or other fuel-gas cylinders, or near any other substance likely to cause or accelerate fire.
Valve protection caps must be kept on the cylinder valve at all times. A hammer or wrench cannot be used to open cylinder valves. If valves cannot be opened by hand, the supplier must be notified.
Cylinders will be kept far enough away from the actual welding or cutting operation so that sparks, hot slag, or flame will not reach them, or fire-resistant shields must be provided.
