Five safety rules for work in or on electrical installations
A set of rules, which are summarized in DIN VDE 0105 as the "five safety rules", are defined
for work in or on electrical installations as a preventative measure against electrical
accidents:
1.
Isolate
2.
Secure against switching on again
3.
Verify that the equipment is not live
4.
Ground and short-circuit
5.
Erect barriers around or cover adjacent live parts
These five safety rules must be applied in the above order prior to starting work on an
electrical system. After completing the work, proceed in the reverse order.
It is assumed that every electrician is familiar with these rules.
