3. Refer to manufacturer
’s service publications for identified high voltage components.
4. Physically locate high voltage components on the vehicle and disable them according
to manufacturer
’s instructions (some components may require a waiting period or
special procedures to discharge the voltage completely).
5. Use Best Work Practices (see below) when performing work on electrical systems.
Best Work Practices:
WARNING - To avoid personal injury or death, permit only trained responsible
and capable persons to operate or maintain the equipment. Carelessly operating
or neglecting maintenance despite the safe design of any vehicle and its high
voltage equipment may result in personal injury or death.
The danger of injury through electrical shock is possible whenever electrical
power is present. Most fatal injuries result from high-voltage exposure; however,
people can sustain severe injuries from low voltage power if it has a high current
flow.
·
Be aware of ALL high voltage equipment on the vehicle; review line-set/build ticket
and the owner and service manuals of high voltage equipment BEFORE starting any
work.
·
When working on this equipment, remain alert at all times. Never work on the
equipment when physically or mentally fatigued, and never work alone near high
voltage equipment.
·
Always stand on an insulated, dry surface when working on any electrical circuit. Do
not handle any kind of electrical device while standing in water, while barefoot, or
while hands or feet are wet.
·
Always work in an adequately illuminated area.
·
Always use appropriate protective equipment: insulated gloves, rubber gloves,
goggles/face shield, safety shoes, protective clothing, and insulated tools when
working on electrical components/circuits of the vehicle.
·
Never wear jewelry when working on this equipment. Jewelry can conduct electricity
resulting in electric shock or burns and may get caught in moving components
causing injury.
·
When working on vehicles that have high voltage devices or equipment, use
appropriate alerting techniques in plain view to warn people that may be in the
general area and to prevent inadvertent activation of any disabled high voltage
circuit(s) during service: safety signs, safety symbols, tags, barricades, cones, etc.
·
Keep a fire extinguisher close by at all times. Extinguishers rated
“ABC” by the
National Fire Protection Association are appropriate for use on the electrical system.
Make sure the extinguisher is properly charged and be familiar with its use. Consult
the local fire department with any question pertaining to fire extinguishers.
·
Ensure that the high voltage power, high voltage power generating equipment, and
high voltage storage devices are disconnected, locked out, or otherwise disabled
BEFORE working on or around the vehicle, its electrical circuits, or components.
