Use electricity safely
Using electricity safely is a very important topic in our daily lives.
First, ensure any electrical items are approved standard when purchasing and keep them correctly maintained. Second, unplug electrical items that are not in regular use and
ensure that you unplug and switch off electrical items when you are away from the house for any length of time . Third, don’t use any electrical items in the bathroom unless specifically
designed for use there, such as shavers and electric toothbrushes. But when you use them, make sure not to get them wet and avoid plugging and unplugging with wet hands. The last, always turn
the electrics off at the mains if carrying out any electrical repairs and only attempt repairs if you know what you are doing.
We should use electricity carefully because items left plugged in can be a fire risk and waste energy if left on standby.
