A permit to work is appropriate in situations of
high hazard/risk and, for example, where there
is a need to:
• ensure that there is a formal check
confirming that a safe system of work is
being followed;
• co-ordinate with other people or activities;
• provide time limits when it is safe to carry
out the work; and
• provide specialised personal protective
equipment (such as br
eathing apparatus)
or methods of communication.
