Static electricity, for the most part, is simply annoying. You get a shock when you go to open the file cabinet. You spark when you go to shake hands with someone (It can actually be quite painful when you go to lock lips for a passionate kiss and that static electricity sparks. Ouch!). Static electricity, however, can also be something to pay serious attention to when you are handling fuel. Improperly grounded fuel dispensers can be extremely dangerous.
For an example of what fuel and static electricity can do, have a look at this video on youtube: http://www.youtube.com/watch?v=DnPz5mx_1AM. This explosion which resulted in the death of the driver was so powerful that it blew the truck up in the air and it landed on the overpass.
Bonding and grounding is not a problem when you fill up your tank at the gas station because it’s built into the pump. It’s all UL approved.
When refueling trucks and heavy equipment, however, it’s important to make sure that the bonding wire is properly attached. It is also important to make sure that you ground the truck as well.
If you handle flammable liquids on a regular basis, make sure that you understand the basics of bonding and grounding.
