Most of us drive vehicles that use gasoline for fuel. If you are like me, we probably notice the signs at the pump island that tell us to stop our engines before refueling but don't give it much more thought than that. Perhaps the reader that suggested this topic is doing us all a favor.
The greatest hazard present when we refuel is static electricity. It is created by flowing fuel and our movements in and out of the vehicle. To minimize the hazard never re-enter your vehicle and then return to the nozzle while filling your tank. If you are filling a container, but it on the ground near the pump. Never fill a container while it is in your vehicle.
Hot sources of ignition are the next greatest hazard. It is mandatory that you shut off your engine, extinguish smoking materials and turn off RV pilot lights before refueling.
Never prop the nozzle control open with anything but the latch built into the nozzle if it is present. When the nozzle shuts off indicating that the tank is full, stop. Overfilling can lead to fuel expansion and an overflow that could result in a fire.
It is illegal to fill anything but an proper gasoline container. Safety conscious service stations will refuse to allow you to put gasoline in anything but an approved container. When filling, use manual control and always keep the nozzle in contact with the container. Seal the container properly, transport and store it in a cool place. Be aware that bylaws that may control storage of gasoline at your home.
There is some indication that using a cell phone while fueling your vehicle may be dangerous as well. To err on the side or caution, it may be wise not to talk on your cell while filling the tank. The fact checking website Snopes says that these reports of danger are false.
In some circumstances, this advice may not apply to the refuel of diesel powered vehicles.
