Carrying Out Electrical Work
Generally you should not work alone with machinery unless it has 'deadman' switches. This is a type of switch often used on electrical machinery. It is designed so that if the operator releases pressure on the switch, handle or pedal because of sudden illness or other causes the current is cut off and the machine ceases to operate.
If you must work alone, the machine's controls should be clearly marked so that another person who may not be familiar with the machine would be able to turn it off in case of an emergency.
 | | Your employer must make sure you are trained in safe work procedures. |
Safety procedures for working with electricity might cover the following points.
