Question: 1 / 400

What must be included in an emergency shutoff system for residential fueling?

Remote access controls

Automatic gas detection

Manual shutdown capability

An emergency shutoff system for residential fueling must include manual shutdown capability because this allows individuals to immediately stop the flow of compressed natural gas in the event of an emergency. Manual controls provide a direct means for occupants or emergency responders to take action when an unexpected situation arises, such as a gas leak or equipment malfunction.

While remote access controls, automatic gas detection, and real-time pressure monitoring contribute to the safety and efficiency of a fueling system, they do not replace the necessity for a manual shutoff option. Remote controls may not always be accessible during an emergency, while automatic systems can fail. Therefore, an easily accessible manual shutdown is an essential element of safety in residential fueling setups.
