Thank you Xena for that timely comment on Static electricity and gasoline
Other Fueling issues you should be aware of:
Never fill gas cans unless the can is sitting on the earth
a gas can, isolated from ground in a car trunk or pick-up bed liner will build a static charge. leaving the can on the earth (ground, concrete, etc) allows the can to be effectivley grounded, the static is safely conducted to ground
DO NOT USE CELL PHONES or 2 Way RADIOS while FUELING vehicles
radio transmiters and cell phones create static charges. they should be off and you should not try to use them while fueling vehicals
KEEP THE NOZZLE IN CONTACT WITH THE FILLER NECK
delivery nozzles are usually aluminum or brass. using non-ferrous metals reduces the hazzards of creating a arc between metal surfaces of the filler neck and the nozzle. Keeping the nozzle in solid contact tends to discourage static charges from building also
-------
Static is a real danger in fueling operations. Did you know that in Bulk tank yards the delivery tanker trucks and all the equipment have to be specially grounded to earth? Large volumes of gasoline flowing in the piping create static charges, grounding systems limit potential between the equipment and protect against sparks.
Aircraft fueling requires the tanker and aircraft to be bonded together, this bonding and grounding limits potentital between the vehicals.
