Has anyone seen the International Fire Code Chapters 53 and 58 applied to natural gas installations in addition to the Fuel Gas Code?
IFC Chapter 53 is Compressed Gasses and Chapter 58 is Flammable Gasses.
It's technically a gas at standard temperature and pressure with a boiling point below 68 deg F at 14.7 psi and flammable range of 5% to 17% by volume in air. Natural gas appears to be subject to these requirements, but I've never seen it this way in practice.
