General Safety Guidelines
 
Use electrical appliances with safe 3-pin plugs (except those not supplied through socket outlets).
   
Arrange registered electrical workers to install electrical appliances not supplied through socket outlets.
   
Adhere to operating procedures and safety precautions stated in user manuals.
   
Check electrical appliances, including their plugs and flexible cords, for any damage before use.
   
Do not use any electrical appliance if its safety or proper operation is in doubt, and have it inspected by qualified persons.
   
Do not connect any electrical appliance designed to operate at 110V directly to a socket outlet. (This type of appliances should carry warning labels).
   
Switch on an electrical appliance only after plugging it into a socket outlet. Otherwise, sparks occurring at the plug may cause fire hazard.
   
Allow sufficient space for heat dissipation to prevent electrical appliances from being damaged due to overheating and to prevent fire from occurring.
   
Keep children away from operating electrical appliances.
   
Avoid placing the flexible cord of an electrical appliance close to any hot object (e.g. a cooking range).
   
Do not use any inflammable substance near an operating electrical appliance.
   
Do not allow water to seep into an electrical appliance to avoid danger.
   
Avoid using portable electrical appliances (e.g. hairdryers, electric heaters, etc.) in bathrooms, except those designed to operate from shaver supply units (e.g. electric shavers and electric toothbrushes).
   
Avoid touching any electrical appliances, socket outlets or switches if hands are wet.
   
Switch off all electrical appliances if a blackout occurs to prevent them from starting simultaneously when the power supply resumes.
   
Switch off electrical appliances when nobody is at home.
   
Maintenance of Household Electrical Appliances
 
Clean electrical appliances regularly according to user manuals.
   
Unplug electrical appliances before cleaning.
   
Arrange electrical appliances to be inspected and maintained regularly by qualified persons.
   
Maintenance of Household Electrical Installations
 
Arrange electrical installations to be maintained regularly to ensure safety.
   
Arrange an electrical installation to be inspected immediately if its safety is in doubt (e.g. frequent tripping).
   
Avoid adding to or altering electrical installations without the consent of the electricity supplier.
   
Arrange all electrical work such as addition, alteration, inspection, testing and maintenance to be carried out by registered electrical contractors. A list of registered electrical contractors is available for reference at EMSD Customer Service Office, Public Enquiry Service Centre of all District Offices and EMSD web site http://www.emsd.gov.hk.
