It is preferable not to use multi-way adapters. Fires can start at the rear of the socket if it is overloaded. Trip circuits and fuses offer little protection.
People often get confused as to how many appliances can be plugged into a multi-way adapter. Check the appliances to see how many amps they use and ensure that the total does not exceed 13amps.
As a general guide, appliances that heat up quickly, e.g. kettle, iron and toasters and, appliances that take large amounts of power, e.g. washing machine, tumble drier, dishwasher will take up to 13amps and should not be included on a multi-way adapter.
If anyone smokes, a policy should be agreed. Smoking is a common cause of house fires and therefore the risks to both themselves and others should be explained. Smoking in bed should be ruled out. The best place to smoke is outside. Emphasize the need to use an ashtray and stub-ends should be properly extinguished.
