Typical hot work permit
of course and not for high risk operations such as hot
works.
Hot work permits should normally include as a
minimum:
wall or partition the opposite side must be examined for
combustible material, the need to provide fi re resistant
coverings where work is being undertaken adjacent to
immovable wooden structures. In addition the checklist
may well include the isolation of existing detection
systems and the requirement for the provision of fi re
fi ghting equipment and competent persons to operate it.
A key element that will also be included in the hot
work permit will be the sign-off following an examin-
ation of the area (at least one hour after cessation of hot
works) to ensure that there are no fi re risks remaining.
A sample of a hot work permit can be found in the
Appendix 8.1, together with a sample hot work checklist
at Appendix 8.2.
The issues relating to highly fl ammable liquids and
LPG have been covered at length in preceding sections
of this chapter; however, quite specifi c to construction/
maintenance operations is the use of items such as tar
boilers, which are invariably powered by gas cylinders.
Tar boilers (and similar equipment) should remain
at ground level remote from the building where reason-
ably practicable. However, where the risk assessment

Separate permit forms may be required for different
tasks such as hot work and entry into confi ned spaces
and therefore different information and records are likely
to be required.
The hot work permit used as part of the safe system
of work will also provide details on checks that will
need to be made prior to the commencement of the
work such as the area being cleared of loose combus-
tible material, if work is to take place on one side of a
