Hazards

Rare or Freak Accident?

The photo before shows the results of a static electricity
discharge at a Chevron gasoline station in Salt Lake City,
Utah, USA (January, 2003)


It started from static electricity. The customer, a teenage
girl, started pumping gasoline using the automatic filler,
and got back in the vehicle. When the pump clicked off,
she got back out of the car and didn't ground herself. She
said she saw a blue flame jump from her hand to the pump
nozzle. The photos show the damage to the vehicle and
nearby equipment. The girl was not injured.


Cold, dry weather can produce the ideal conditions for a
static discharge.


Safe Refueling and Fuel
Handling Guidelines


Here are some refueling and fuel safety
guidelines that will help keep you and
your family safe when refueling your
vehicle or filling up gasoline storage
containers:


Safe Refueling and Fuel
Handling Guidelines

Turn off your vehicle engine while refueling.
Put your vehicle in park and/or set the
emergency brake.
Disable or turn off any
auxiliary sources of ignition such as a camper
or trailer heater, cooking units, or pilot lights.

Do not smoke, light matches or lighters while
refueling at the pump or when using gasoline
anywhere else.



Safe Refueling and Fuel
Handling Guidelines

Use only the refueling latch provided on the
gasoline dispenser nozzle,


never jam the
refueling latch on the nozzle open.

Do not re
-
enter your vehicle during refueling.

In the event a static
-
caused fire occurs when
refueling, leave the nozzle in the fill pipe and
back away from the vehicle. Notify the
station attendant immediately.

Do not over
-
fill or top
-
off your vehicle tank,
which can cause gasoline spillage.

Potential Cell Phone Hazard


Combustible Gases + Cell Phones = Explosions

TURN OFF CELL PHONES

BEFORE ENTERING

SITES WITH POTENTIAL

EXPLOSIVE MIXTURES





BACKGROUND

An employee on an offshore drilling rig received second degree burns
when he answered his cell phone while working on a panel which
contained an explosive mixture of gas. Similarly, a driver suffered burns
when gasoline fumes ignited causing an explosion as he was talking on
his mobile phone while his vehicle was being fueled. Many mobile
phone makers print cautions in their user handbooks that warn against
mobile phones in gas stations, fuel storage sites, and chemical factories.




Best Practices


Read your instruction book. Mobile phone makers such as Motorola,
Ericsson, and Nokia print cautions in their user handbooks that warn
against mobile phones in gas stations, fuel storage sites, and chemical
factories.


Turn off your mobile phone before entering any area with a
potentially explosive atmosphere (For example: areas around degas
wells; coal storage areas; fueling areas, such as gas stations; below
deck on boats; fuel transfer storage facilities; chemical transfer and
storage facilities; and areas where the air contains chemicals or
particles, such as coal dust, grain, dust, or metal powders).


Do not transport or store flammable gas, liquid, or explosives in the
same compartment of your vehicle that contains your mobile phone
and its accessories.
