Consumer owned gas pressure boosters must be what type?

Consumer owned gas pressure boosters must be what type?

• A. Explosion-proof
• B. Open-frame
• C. Non-return
• D. Hermetically sealed

Answer: (D)

The main safety idea here is keeping the booster’s enclosure gas-tight to prevent leaks and protect the surrounding space. A consumer‑owned gas pressure booster should be hermetically sealed so that any natural gas within the unit cannot escape to the room and air cannot enter to form flammable mixtures around the electrical components. This tight seal helps prevent ignition sources inside from affecting the outside environment and protects occupants from potential gas leaks. An explosion‑proof design is geared toward containing a blast inside a enclosure, which isn’t the requirement in this case; an open-frame unit would expose wiring and allow gas or moisture in, and a non-return device doesn’t address enclosure safety.
