Precautions while using Electrical Equipment
Reduce the voltage
Reduce the voltage Using lower voltages can reduce or eliminate the risks of electric shocks and burns: 1 portable tools are available which can be run from a 110 volts, centre tapped to earth supply, (usually from a transformer) 2 where electrically powered tools are used, battery operated are safest. 3 temporary lighting can be run at lower voltages, e.g. 12, 25, 50 or 110 volts.
