What happens if a CNG Bypass Cart cannot support the building?

What happens if a CNG Bypass Cart cannot support the building?

• A. You would lose integrity on the pipe and need to relight the building.
• B. The building will be automatically powered by backup generator.
• C. The gas will vent to atmosphere.
• D. The cart will automatically adjust.

Answer: (A)

The bypass cart is meant to provide a temporary, safe gas supply to the building when the main line can’t, keeping pressure and flow adequate for the building’s needs. If that cart cannot support the building, the piping system can’t maintain safe pressure or sufficient gas flow, so the building’s gas service can’t be sustained. In that situation, the gas supply to the building is effectively lost and crews must shut it off and then re-light the appliances once the system is restored and safe to do so. The other options don’t fit because a bypass cart doesn’t automatically power the building with a generator, it doesn’t vent gas to atmosphere as a normal outcome, and it isn’t assumed to auto-adjust to always meet demand.
