I'm confident that I've posted this here before...
Just remember, that if you put "electrical appliances" in your hangar (i.e. refrigerators, air compressors, radios, etc.) then please do everyone a favor and keep them at "table top" height or higher.
There's a reason outlets in a hangar that was built to code are at light switch height. It's because gas fumes are heavier than air and they sink to the ground.
No doubt about it...no fool should fuel an aircraft in an enclosed hangar.
But it's also a fool who leaves electrical appliances sitting on the floor waiting for the gas vapors to arrive from a neighboring hangar. Also, fuel bladders, sumps, etc., can and do spring leaks.
Live electrical components, or worse, unsealed motors at floor level, can spell disaster.
I won't even keep extension cords plugged in and laying on the floor.
I also approach all electrical devices in my garage at home with the same caution. Everything electrical is kept at least 3' off the floor.
Granted, the chances are probably quite slim...but it's not a chance that I'm willing to take especially since I'm in a ten unit T-hangar and could affect many others.
