Safety Tips for Using Electricity
According to the Electricity Ordinance, all electrical work including installation, repair and testing should be carried out by Registered Electrical Worker (REW).
Main Switch
- Check to see that the main switch is in good condition
- Label "ON" and "OFF" clearly
- Be readily accessible in case of emergency
- Familiarise yourself with the location of the main switch
Residual Current Devices (RCDs)
- Use RCD to protect yourself from shock. They are especially important in kitchens, bathrooms, and places where water is present
- Test the RCDs regularly according to the manufacturer's instructions at least every three months
Circuit Breakers/ Fuses
- Choose correct rating and type of circuit breakers / fuses
- Label each circuit breaker / fuse to indicate which circuit it protects
- Replace the blown fuse with a new one of the proper size and rating. Never substitute a fuse with other objects, such as a coin or paper clip
- Know how to reset circuit breakers, and replace blown fuses properly. Before conducting any replacement, turn off the appliances and lights in use
- If the appliances are unplugged but the circuit breakers flipped off again, there could be a fault on that circuit. You should seek assistance from a qualified electrician
Socket Outlets
- Avoid excessive use of extension units or universal adaptors
- Check for outlets that are loose-fitting or broken
- Arrange replacement for any broken or missing wall plates
- Place safety caps in all unused outlets, especially the ones that can be accessed by children
Plugs
- Use plugs that comply with local / international statutory safety requirements for use in Hong
Kong - Check the plug itself. Look for signs of damage or discolouration on the plug
- Make sure the power cord is firmly clamped in the plug
- Don't force a plug into an outlet if it doesn't fit
Cords
- Check if cords are in good condition – no part of the cable is worn, split, cracked or frayed.
Arrange for replacement if necessary - Insert or remove a plug by grapping the plug itself, not the cord
- Do not run electrical cords underneath carpets, rugs or furniture. Keep them away from hot
appliances and corrosive materials - Cover power cord with rubber protector strip if it has to be laid across a pathway
- Unplug the appliance from socket outlet before detaching a detachable power cord from the
appliance
Lighting
- Schedule regular checking for damaged fittings, cables and connections
- Bulbs should be screwed securely into the fixtures. Loose light bulbs can lead to overheating
- Don't use bulbs that require higher wattage than the fixture allows
- Ensure outdoor lighting fittings and luminaires are weatherproof
Appliances
- Use appliances that meet local / international safety requirements for use in Hong Kong
- Check condition of appliances
- Never cover up ventilation holes or slots on appliances
- Inspect for damaged wiring, plugs, and connectors
- Never touch an appliance with wet hand
- Don’t touch the plugged-in appliance if it drops into water. Turn off power and unplug the
appliance - Get appliance inspected by qualified electrician if it constantly blows a fuse, flips a circuit or feels
tingling on contact, or has a burning smell / sizzling sound
Outdoor Use Safety
- Make sure each electric tool is grounded or certified with double insulation
- Never use appliances that are not designed for outdoor use
- Don't use electric-powered appliances or tools outdoor when it is raining, on wet grass or in damp area
- Use only extension cords marked for suitable outdoor use
- When using a ladder outside, keep yourself, tools and ladder well away from power lines
