is it necessary for people to shut off their cars while refueling?

Answer 1

Whatever ever happened to better be safe than sorry? In most cases, you won't blow yourself up. But do you really want to be around in that .00001 chance that you will? Don't you have plans for yourself that don't include being a toasted marshmallow?!?

Answer 2

It is NOT necessary to switch off the engine. I refuel my car always without knocking the engine off. Neither has my car cought fire while driving pass a tanker that is refilling the underground tank. I am living proof. Its an Internal combustion engine and not external combustion. What about the cars that has turbo timers that still runs when you take the key out of the ignition? wouldnt it be annoying to only fill the car 2 minutes later when the car shuts off? petrol does not have such a low flash points (temperature at which a particular substance can ignite)

UNLESS, your fuel filler cap is very near the engine and there is a potential to accidentally spill fuel over the engine components.

Answer 3

Q: Engine Running
Why is it dangerous to leave your car running?

A: Many people believe this safety warning only applies to older cars. That is not true. A running car presents a number of "ignition sources" for fuel vapor. The exhaust components of a modern car can literally glow red hot during normal operation. The typical ignition system creates voltages above 40,000 volts.

But turning off your engine while refueling isn't just to prevent your car from starting a fire. There is also a safety issue in the event of fire, regardless of the source. In case a fire does occur in a gas station a running car is a danger. Imagine that fire burns through one of the rubber fuel hoses under your running car. Most fuel pumps deliver gasoline at about 15 to 40 pounds per square inch (PSI). Your fuel pump is now spraying a tremendous amount of gasoline at an open flame.

Answer 4

Yes. The high voltage coil in a car can create a spark outside of the internal combustion engine. If there are enough vapors around, this could start a fire. However, the only time there are likely to be enough gasoline vapors in the air is when the tanker truck is there refilling the USTs (Underground Storage Tanks).

Answer 5

Nah. Look at any car race on TV. Do any of them shut the car off when they refuel? Nope.

Answer 6

it is very important to shut off engines, stay out of your car, and don't smoke while refueling. it could cause a fire if not an explosion. so think safety before you do something dangerous.

Answer 7

As long as you stay out of the car while it's running. If you sit back down in the car you usually cause static electricity and if you then go straight for the gas handle the electricity can cause a fire! Just be careful if you do leave it running!!!

Answer 8

of course not if your aim is to DIE when you blow the whole gas station up or catch on fire from a spark and yea what tom said, you have your alternator making electricty, your exhaust makeing ambient heat and everything else to ignite vapors and then the hose thing...... just think high power flame thrower with a 20 to 35 gallon tank thats not going to empty for about 2 hours if its full

Answer 9

yes, or else while refueling the new gas will touch the engine and will spark a flame

Answer 10

Yes
