6 m or by a barrier of noncombustible material at least 5 ft.

Oxygen and acetylene cylinder storage requirements.

1910 253 b 4 iv. Csa w117 2 12 r 2017 safety in welding cutting and allied processes. Acetylene cylinders are not designed for use in environments where the temperatures may exceed 52ºc 125ºf. Store oxygen cylinders and fuel gas cylinders separately.

Twenty four hours of inactivity is the answer that i frequently hear. We look at both separately below. Take care to store small cylinders properly as they don t have protection caps on them. In the storage facility both types of cylinders must be kept separate.

Indoors separate oxygen from fuel gas cylinders by at least 6 1 m 20 ft or by a wall at least 1 5 m 5 ft high with a minimum half hour fire resistance. Acetylene cylinders must be always stored in the upright position with valve caps on. Nfpa 51 2 4 3 oxygen cylinders in storage shall be separated from fuel gas cylinders or combustible materials especially oil or grease by a minimum distance of 20 ft. Local jurisdiction requirements may vary.

The barrier shall interrupt all lines of sight between oxygen and fuel gas cylinders within 20 ft. But is this assumption correct. 1926 350 a 10 oxygen cylinders in storage shall be separated from fuel gas cylinders or combustible materials especially oil or grease a minimum distance of 20 feet 6 1 m or by a noncombustible barrier at least 5 feet 1 5 m high having a fire resistance rating of at least one half hour. The general industry and construction standards only specify the requirements for storage and use but not how long the oxygen and acetylene cylinders sits idle before it s considered in storage.

That means they must be returned to storage at the end of a workday even if they will be used together the next day. Up to 300 ft3 approximately 12 13 e cylinders is permitted to be stored within a 22 500 ft2area without requiring to be in a special storage location. Risks and hazards of acetylene and oxygen gases. Acetylene cylinders and oxygen cylinders both have their own unique risks and hazards and must never be stored together as they can react dangerously with one another.

Oxygen cylinders in storage shall be separated from fuel gas cylinders or combustible materials especially oil or grease a minimum distance of 20 feet 6 1 m or by a noncombustible barrier at least 5 feet 1 5 m high having a fire resistance rating of at least one half hour. Cylinders that are in use or available for immediate use do not need to be included in this determination. Storage for safety purposes oxygen and acetylene cylinders have to be stored a minimum of 10 feet from each other.
