Safe work practices - Managing electrical safety in the
workplace
Employers must carry out a risk assessment to identify potential workplace
electrical hazards and to access the likelihood of injuries from the exposure
to these hazards. This will enable appropriate control measures to be
implemented.
General precautions - Always ensure that:
• An accessible and clearly identified switch near each fixed machine
to cut off power in emergency is provided.
• For portable equipment, socket-outlets are close by so that equipment
can be easily disconnected in an emergency.
• Electrical equipment used in flammable/explosive atmospheres should
be designed to stop it from causing ignition.
• Double adaptors and 'piggy back plugs' are not used.
• The wattage of all bulbs in light fixtures and lamps are checked
to make sure they are the correct wattage. Replace bulbs that have a higher
wattage than recommended to prevent overheating that could lead to a fire.
• Lightbulbs and other equipment which could easily be damaged in
use are protected. There is a risk of electric shock if they are broken.
• Suspect or faulty equipment is taken out of use, labelled 'DO
NOT USE' and kept secure until examined by a competent person.
• Where possible, tools and power socket-outlets should be switched
off before plugging in or unplugging.
• Equipment is switched off and/or unplugged before cleaning or
making adjustments.
• There is provision for all equipment to be stored carefully, securely
and safely.
• Workers using electrical equipment are trained and supervised.
• Electrical installations are safe eg, by providing enough power
outlets.
• Worn or frayed cords are replaced.
• Leads, wiring and cables are in good condition and in the correct
position.
• PVC insulation tape should not be used to repair damaged cords.
Have the cords replaced.
• Machinery is unplugged before cleaning.
• Enough socket outlets are providing – overloading socket
outlets by using adaptors can cause fires.
• All connections to power points are made using the correct plugs.
• Isolating transformers and residual current devices (RCD) are
used.
• The electricity supply is isolated from earth and has a voltage
between conductors not exceeding 230 volts.
• No part of a crane, digger, excavator, drill rig or other mechanical
plant, structure or scaffold is brought closer than 4 metres to an overhead
line without the written consent of the powerline owner.
• Equipment suitable for the working environment is used, eg, cordless
tools for wet and damp conditions.
•Electric risks can sometimes be eliminated by using air, hydraulic
or hand-powered tools.
•The main board is locked and the switches are safe and identified.
