General Household Electrical Safety Tips

   
To ensure that you have a safe household environment, you must buy safe household electrical appliances, and use them properly and maintain them appropriately.
   
Buy only electrical appliances which meet the local statutory safety requirements for use in Hong Kong. Ensure the appliances are suitable for use under the local power supply conditions (e.g. rated voltage and frequency) and environmental conditions (e.g. temperature and humidity).
   
Electrical appliances must bear the proper markings as shown on the diagram or be accompanied with a notice indicating the same.

For all fixed electrical appliances which do not receive power supply from socket outlets, the connection of power supply must be carried out by a registered electrical contractor.
   
To prevent electric shock, electrical appliances must be effectively earthed, i.e. the metallic casing of an electrical appliance is connected to the "earth" pin of its plug. Electrical appliances without earth connection must be of double insulation or reinforced insulation design, and such appliances usually bear a symbol "回".
   
Electrical appliances must be accompanied by proper operation manuals depicting the installation, assembly and operation procedures and safety precautions. Adhere to the instructions given in its manual when using an electrical appliance.
   
Before use, check electrical appliances (including plugs and flexible power cords) to see if they are damaged or worn-out, especially when they have not been used for a prolonged period of time.

Electrical appliances must be fitted properly and with robust structures for stable operation. Under normal operation, there should not be any sign of overheating (e.g. discolouration, charring and deformation) or difficult starting, excessive noise or vibration, crack or loosen part. If the safety of an electrical appliance is in doubt, stop using it and hand it to an experienced technician for inspection.

To prevent socket outlet overload, do not connect electrical appliances with high power consumption to the same socket outlet.
   
Do not use any inflammable chemical substance (e.g. insecticide and thinner) near an operating electrical appliance.
   
For safety, before going out, electrical appliances (other than essential appliances) should be switched off as far as practicable.
