Store oxygen cylinders and fuel gas cylinders separately.
Oxygen and acetylene cylinder storage requirements.
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.
That means they must be returned to storage at the end of a workday even if they will be used together the next day.
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.
1 5 m high having a fire resistance rating of at least 1 2 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.
Storage for safety purposes oxygen and acetylene cylinders have to be stored a minimum of 10 feet from each other.
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.

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.
Local jurisdiction requirements may vary.
1910 253 b 4 iv.
Acetylene cylinders are not designed for use in environments where the temperatures may exceed 52ºc 125ºf.
Cylinders that are in use or available for immediate use do not need to be included in this determination.
Risks and hazards of acetylene and oxygen gases.
Take care to store small cylinders properly as they don t have protection caps on them.
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.
But is this assumption correct.
No there is not a specific number of cylinders that are permitted outside of storage.
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.
The barrier shall interrupt all lines of sight between oxygen and fuel gas cylinders within 20 ft.
We look at both separately below.
In general industry workplaces oxygen and acetylene cylinders that are in use or are connected for use will not be considered to be in storage for purposes of the 1910 253 storage requirements 1 osha also will not cite a general industry employer if a single oxygen cylinder and a single acetylene cylinder are maintained with their cylinder valves closed and valve protection caps affixed.
