Electricity can kill and maim people by:
The most common voltage involved in electrical accidents is 230 volts (normal mains voltage). A large proportion of electrical accidents happen to persons who are electrically skilled working on equipment falsely thought to be dead
Equipment and systems should be selected erected and tested in accordance with appropriate standards eg BS7671 for installations up to 1000volts
There should be a systematic procedure in place to regularly check the electrical system including any portable equipment
Only competent persons should carry out work on electrical systems
Isolation and testing should take place before working on electrical equipment
