How far in feet must an emergency shutoff switch be located from LP-gas motor vehicle dispensing systems?

The correct distance for locating an emergency shutoff switch from LP-gas motor vehicle dispensing systems is 100 feet, while it must be at least 20 feet away from the dispenser location. This requirement ensures that in the event of an emergency, a person can safely turn off the gas supply without being in proximity to potential dangers or hazards associated with an LP-gas leak or fire.

Maintaining a distance of 100 feet serves a dual purpose: it helps to ensure that the shutoff can be accessed quickly without exposing personnel to risk, and it also minimizes the chances of ignition sources in the event of a leak.

Positions closer than this recommended distance could result in increased risk for individuals trying to operate the shutoff switch during an emergency, which is why regulatory guidelines have established such specific distances to enhance safety in these environments.
