Does IFC Chapter 53 & 58 Apply to Natural Gas?

9/30/2020

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.

LNG shall comply with the requirements of NFPA 52 and NFPA 59A.

Not chapter 53 or chapter 58

IFC 2018 chp. 53 and 58 would apply as a safety concern. Local AHJ's utilize the IFC and NFP's to address yearly safety issues. Also, these 2 chapters address requirement regarding compressed gases. It give you reference on other codes that need to be follow during and after installation such as NFPA 52, NFPA 55, NFPA 59A.

IFC 2018 Chp. 53 and 58 also reference IFC chapter 23 if LPG and CNG is to be used as fuel-gas station. Chp. 61 also regulate LPG.

Thanks Felipe. I see Ch 6 also clears up some of the code overlap.

This makes sense. Thanks for your help.
