Underground cables and pipes
Make sure that authorities or companies responsible for cables
and pipes have been contacted and that their instructions are
followed. Also check which rules apply to ground personnel
regarding exposing cables and pipes. Normally only the service
companies' own personnel may expose and arrange provisional
suspension of cables.
Make use of a signal man when you cannot see the actual point
where you are working or when the position of the pipe or cable
is critical, see page
243 . The position of the pipe or cable may
deviate from the drawing or distances may be incorrectly
determined. Regard all electrical cables as live.
