The term "electrical safety" broadly refers to the safety of generation, transmission, distribution and use of electricity. As far as members of the general public are concerned, the distribution and use of electricity in residential premises are the two aspects which have close relation to our household safety.
Unsafe electrical appliances and electrical installations may cause fire, and the use of them may also cause electric shock and injury. To protect your family members and properties, you must ensure that you have a safe household environment (including your building and residential units) by paying attention to electrical safety.
You must buy safe household electrical appliances, and use them properly and maintain them appropriately. To ensure the safety of the electrical installations in your residential premises, you must employ registered electrical contractors to carry out periodic inspection and maintenance, and to ensure that there is no illegal addition or alteration.
