Special Safety Information on Static Electricity 

 

30

Static electricity and filling gasoline: 

Static electricity can initiate from ungrounded gasoline tanks or containers, from flowing 

gasoline, and from persons carrying a static electric charge

 

 

Static electricity on numerous occasions has explosively ignited gasoline vapors that were present during 
fueling processes, resulting in serious burns to nearby persons.  To avoid static electricity while fueling, 
certain steps must be followed before and during the fueling process in order to minimize and safely 
dissipate static charge build-up.   

 

Filling Portable Containers at Service Stations: 

 

Use a portable container to fill grinder tank.  Never fill the grinder's gas tank directly from the service 
station's fuel dispenser pump – the grinder's tank is not grounded and the high velocity flow of gasoline 
from a fuel pump can cause static electric build-up.  Use an approved portable container to transfer 
gasoline to the grinder's tank.  

 

Use a portable container made of metal or conductive plastic.  

 It will dissipate charge to ground 

more readily. 

 

Fill container on the ground.

  Never fill the portable gas container while it is sitting inside a 

vehicle, trailer, trunk, or pick-up truck bed.  ALWAYS place container on the ground to be filled.    

 

Touch a grounded metal object before starting

.  Always dissipate static charge from your body 

before beginning the fueling process by touching a grounded metal object at a safe distance away 
from fuel sources. 

 

Keep nozzle in contact with container

.  Keep fuel dispenser nozzle in contact with the portable 

container at all times while filling at a service station. Do not use the nozzle lock-open device on 
the dispenser hose. 

 

About static electricity and fueling 
Many common objects can accumulate and retain a static electric charge.  Objects made of non-
conductive materials (e.g. plastics) easily accumulate and retain static electric charge, as can objects 
made of conductive material (e.g. metal, water) if they are not electrically grounded.  The static electric 
charge on an object, such as a human body or plastic fuel tank/container, can reach as high as several 
thousand volts! 

 

A static electric spark can be generated if the static electric charge stored on an object "jumps" to 
another, less charged object.  Such a spark can ignite invisible gasoline vapors that are present during 
fueling situations. 

 

Typical sources of static electric hazards during fueling 
The following objects can accumulate a static electric charge and cause an ignition spark in typical 
fueling situations: 

 

 

Ungrounded tanks/containers.  Any ungrounded fuel tank or container can accumulate a static 
electric charge as a result of contact with other objects or friction during transportation.  This static 
electricity can discharge as a spark to the grounded gasoline dispenser nozzle, as the nozzle is first 
brought close to the tank/container at the beginning of the fueling process. 

 

Flowing gasoline.  Most people are not aware that gasoline accumulates static electric charge while 
flowing through a hose or pipe. This charge then transfers to and accumulates in the gas tank or 
container that is being filled.  The total amount of charge accumulation depends on the amount of gas 
pumped into the container, the speed with which it is pumped, and whether or not the tank/container 
is grounded.  If sufficient static electric charge accumulates in the fuel tank or container during the 
fueling process, the tank/container may discharge a spark to the grounded gasoline dispenser nozzle. 

 

Persons.  A person dispensing the gasoline can carry a static electric charge on their body, typically 
resulting from contact with their car seat or electronics.  The static electricity can discharge as a 
spark between that person's hand and either the grounded dispenser nozzle or the fuel tank opening.
