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.
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.
We look at both separately below.
