Hot Work:

A hot work permit, your best ally for safe work!


Because hot work is the third leading cause of workplace fires and is also responsible for accidents and occupational disease, it is best to know how to supervise it.

The National Fire Code (NFC) Application ( defines hot work as: ‘’Hot works involving open flames or producing heat or sparks (including, without being limited to, cutting, welding, soldering, brazing, grinding, adhesive bonding, thermal spraying and thawing pipes), inside and outside of buildings”.

Alternate method

When a task that meets the definition of hot work must be performed, one must first consider whether an alternate method is available. For example, instead of cutting with a saw or with a blowtorch, it is possible to use manual hydraulic shearing.

Designated area

If hot work is unavoidable, one must prioritize that it be performed in an area said to be designated. When the work cannot be performed in this intended area, it must be ensured that preventative measures specific to hot work be implemented.

The hot work permit

The hot work permit, in addition to being a legal requirement (NFPA 51B art. 5.4.1), has proven itself thus far to be the best tool in preventing potential risks incurred during hot work.

The permit covers the following points:

  • Identification of workers
  • Date and time of beginning and end of work
  • Nature of work
  • Preparation of the work area
  • Identification and condition of work tools
  • Conformity of surveillance during and after the work

Moreover, hot work permits issued in the workplace must be kept, audited. They constitute proof of management to the CNESSTand to insurance companies.
