HEALTH & SAFETY EXECUTIVE GUIDAN
People who move these vehicles
around the workplace should be
aware that others may not hear it
approaching them.
Similarly, people who work around
E&HVs should be aware that they
may move without warning.
Pressure washing has the
potential to damage high voltage
electrical
components
and
cables. High voltage cables are
usually coloured orange.Refer
to guidance from manufacturers
before valeting in any under body
areas including the engine bay.
INCIDENT RESPONSE
INCLUDING EMERGENCY
SERVICES AND VEHICLE
RECOVERY
Vehicles should be visually
checked for signs of damage to
high voltage electrical components
or cabling (usually coloured
orange). Consider whether the
integrity of the battery is likely to
have been compromised.
Shorting or loss of coolant may
present ignition sources in the
event of fuel spillage. If the vehicle
is damaged or faulty, and if safe
to do so, isolate the high voltage
battery system using the isolation
device on the vehicle. Refer to
manufacturer’s instructions for
guidance.
During any recovery, onto a
recovery vehicle, the remote
operation key should be removed
to a suitable distance and
the standard 12/24v battery
disconnected to prevent the
vehicle from being activated/
started.
Have access to reliable sources
of information for specific vehicle
types. For example mobile data
terminals used by fire and rescue
services or by reference to
manufacturer’s data.
Avoid towing E&HV vehicles
unless it can be determined that
it is safe to do so. Dangerous
voltages can be generated by
movement of the drive wheels.
MAINTENANCE AND REPAIR
EXCLUDING HIGH VOLTAGE
ELECTRICAL SYSTEMS
Refer to vehicle specific sources of
information from the manufacturer
and trade bodies to identify
precautions necessary to prevent
danger.
Remote operation keys should
be kept away from the vehicle to
prevent any accidental operation of
electrical systems and accidental
movement of the vehicle.
Keys should be locked away with
access controlled by the person
working on the vehicle. If the key
is required during the work the
person working on the vehicle
should check that the vehicle is in
a safe condition before the key is
retrieved.
Visually check the vehicle for
signs of damage to high voltage
cabling (usually coloured orange)
or electrical components before
starting any work on the vehicle.
Unless a specific task requires the
vehicle to be energised always
isolate or disconnect the high
