Natural Gas Containment piping

Here's an answer from chatgpt:

Secondary containment for gas piping is typically required when the gas piping is located within a building or structure and there is a potential for gas leakage. The specific requirements for secondary containment may vary depending on the type of gas being transported and the relevant building and safety codes.
For example, the International Building Code (IBC) requires secondary containment for gas piping that is located within a building or structure and that carries flammable gases, such as natural gas or propane, if the piping is located in a space where gas could accumulate and create a hazard. The IBC also requires that the secondary containment be designed to withstand the pressure of the gas being transported and that it be capable of containing the entire volume of gas that could be released in the event of a leak.
Other codes and standards, such as the National Fire Protection Association (NFPA) 54 and 58 standards, may also require secondary containment for gas piping depending on the specific circumstances and hazards involved.
It's important to consult with local building and safety codes to determine the specific requirements for secondary containment for gas piping in your area.

And another:

Secondary containment for gas piping is typically required in situations where a gas leak could pose a safety hazard or environmental risk. This can include situations where gas piping runs through areas that could be damaged or disrupted, such as near underground storage tanks, near water sources or drainage areas, or in areas with heavy vehicle or foot traffic.
Specific regulations for when secondary containment is required can vary depending on the type of gas being transported, the location of the piping, and other factors. For example, the Environmental Protection Agency (EPA) has regulations for secondary containment for hazardous materials, which may include certain gases.
It is important to consult with local and national regulations and safety standards to determine if secondary containment is required for gas piping in a particular situation. Additionally, a professional engineer with experience in gas piping design and safety can provide valuable guidance and recommendations for ensuring safe and compliant installation and operation of gas piping systems.
 
Check the pressure that the pipe is under. Am not close to my reference info but I think over a half pound (14" w.g.) is not allowed inside of most,non-industriall spaces, but I think the double pipe might be a solution if higher pressure line really needed
 
I am doing a first time plan review where they want to install hydrogen lines into a warehouse to fuel fork trucks. All storage and pumps for the gas is exterior I can't find anything about secondary containment for gas piping in the IBC. What section is it?

They would be better off not bringing hydrogen into the building. The requirements for containment and explosion proof everything, everywhere all of the time can be draconion. They should have a talk with the insurance carrier. Seriously, hydrogen causes a stir.

I'd start with Ch. 58 of the IFC.
 
I asked because ICE said it was in the IBC



We have not adopted the the IFC here.
The IFC is a referenced standard that does not have to be adopted because it is referenced by other adopted codes. Chapter 7 of the IFGC is adopted by PA and chapter 7 which directly references the IFC in multiple locations. In addition, there may be NFPA standards that will absolutely apply by referenced standards.

Sorry if I misled you. I am not saying that hydrogen containment is mentioned in the IBC. As others have said, the IFC is where you will find the answers. The Electrical Code will play a big role also.

The pipe itself might not be an issue as long as it is out of the way of any possible physical damage. The dispenser and the actual forklifts might be a sticking point.

I had a case where there was a hundred forklifts with lead acid batteries. The insurance carrier insisted on a hydrogen capture arrangement at the point of the battery chargers. Hydrogen being lighter than air resulted in four fans on the roof with a curtain hanging down eight feet. There was a bunch of EMT running through the the capture zone and a group of generic hood fans. Oh and an electrical engineer. We had to have meetings.

The building is 600K sq.ft. The ceiling/roof is 42' high. The batteries put out a negligible amount of hydrogen. It was a strange idea that would never work.

This picture is from a post at the Average Day thread. There were four fans. The fans were supposed to rotate on 24 hour cycles and if one pair failed, the other pair would keep running. The contractor was pleased as punch and put a lot of work into the hanging curtian.
