CONSTRUCTION SITES (SAFETY) REGULATIONS - REGULATION 47

Use of electricity on construction sites

Caution: This is a past version. See the current version here.

(1) Where workmen employed at a construction site are liable to come into
contact with any live electric cable or apparatus, the contractor responsible
for the site shall, both before the commencement of the work at the site and
during its progress, take such measures (whether by rendering the cable or
apparatus electrically dead or otherwise) as will prevent them from being
endangered by the cable or apparatus.

(2) A contractor responsible for a construction site where there is any
electrically charged overhead cable or apparatus shall take such precautions,
by the provision of adequate and suitably placed barriers or other means, as
will prevent the cable or apparatus from being a source of danger to workmen
employed on the site (whether as a result of a lifting  appliance coming into
contact with the cable or apparatus or otherwise).
