How far must all ignition sources be from a motor fuel dispenser?

The correct distance that all ignition sources must be from a motor fuel dispenser is 25 feet. This safety requirement is established to minimize the risk of fire or explosion that can occur due to the flammable vapors emitted from Liquefied Petroleum Gas (LP-Gas) when it is being dispensed.

The 25-foot rule is based on the understanding that within this distance, the likelihood of an ignition source, such as an open flame or spark, igniting the fuel vapors increases significantly. By maintaining a safe distance, the potential for accidents is greatly reduced, protecting both the individuals involved in dispensing as well as the general public and property nearby.

In this context, other distances, like 10 feet, 15 feet, or 50 feet, may not provide the same level of safety. A distance of 10 or 15 feet might not be sufficient to effectively mitigate the risks associated with flammable vapors, while a distance of 50 feet may be overly cautious and not typically required by regulations, leading to unnecessary limitations in the placement of dispensers or related equipment.
