ANSI / OSHA Standards Search

[BobLfoot 301]

I am looking at a project which will use an Open Natural Gas Flame to modify the product passing the automated cell.  My question is what OSHA / ANSI standard is there for Piped natural gas to an open flame?  I can find Bottle Gas and Oxy?Acet standards but nothing that seems to directly apply.  Thoughts anyone?

Turns out NFPA 54 - National Fuel Gas Code is the most applicable.
