sessed prior to undertaking installation or maintenance
operations.
HEAVY
EQUPMENT
All manual handling must be in accordance with the Manual
Handling Operations Regulation 1992
LETHAL VOLTAGES
Electrical power within this system/equipment is at a level
considered, by the low voltage directive 73/23/EEC, to be
sufficient to kill.
Always assume conductors are live until proved dead.
Before attempting any maintenance task, ensure that equipment
is isolated from electrical supply.
When the electrical supply cannot be isolated,
testing/maintenance tasks are to be undertaken only by
personnel who are aware of the dangers involved and after all
necessary precautions have been taken.
WORKING PRACTICES
Unauthorized interruption of the system may endanger the safe
operation of the railway. Before attempting any maintenance on
the equipment, obtain the necessary permission from the rele-
vant authority. Ensure the consequence of any interruption has
been fully considered and understood.
If a component or equipment becomes overheated or burnt, a
toxic fume hazard may exist. Isolate the power to the
equipment, ventilate the area and allow the equipment time to
cool before carrying out repairs.
This equipment does not liberate any toxic or injurious gases
during normal operation.
When working on equipment, especially in the confines of a case,
do not wear metal rings, bracelets, watches, etc. These articles
can cause personal injury or damage to equipment by becoming
entangled in components or causing a short circuit.
