Most jurisdictions in north America use the NFPA standards for the
purposes of defining the fire and safety codes. I am not an expert
in the field but I think this is the document you are looking for.
For more info on code 51 2002 revision go to
Using detailed schematic drawings showing different system layouts,
NFPA 51 provides fire safety requirements for gas-fueled systems for
cutting, welding, and other similar processes.
Standard 51 covers:
- Cylinder storage
- System Manifolding and piping
- Associated protective equipment such as regulators
Also provided are requirements for the use of acetylene generators,
calcium carbide storage for acetylene generators*, and mobile
acetylene trailer systems.
The 2002 edition features clarified text, such the application of
requirements to different size single fuel gas cylinder systems.

Another document NFPA 51B - Standard for Fire Prevention during
Welding, Cutting, and Other Hot Work is not worth looking into in my
opinion as it is aimed at the use of welding equipment and fire
watches in the industrial and building sectors.
In general the NFPA standards are the most conservative approach and
often what gets adopted locally is either straight from their
standard or a watered down version because of lobbying by special

As an example for well over 50 years NFPA has called for sprinklers
in all high rise occupancies, however in most cities builders and
developers have led successful fights against them based on the cost,
even though it is provable from an engineering and statistical point
of view that properly designed, installed and maintained sprinkler
systems are effective in preventing loss of life and property,
fortunately the tide is changing and they are increasingly being
