Hot Works Permit


Hot works is a temporary process that can become a source of ignition when flammable material is present or can be a fire hazard regardless of the presence of flammable material in the workplace.

Hot Works includes any process that generates flames, sparks or heat. Such activities might include:
■ Cutting
■ Welding
■ Brazing
■ Soldering
■ The use of blowlamps
■ Abrasive disc cutting

When flammable materials are present, processes such as grinding and drilling also become hot work processes.

Before carrying out any hot work, a careful assessment of the works should be made.

Other safer options should be considered such as:
■ Using cold cutting or cold repair techniques
■ Replacing rather than repairing.

Where this isn’t practical, a hot works permit must be completed.

The intention of the hot works permit is to check that certain actions and precautions are in place to reduce the risk of a fire occurring as a result of a hot process.

The risk arising from hot processes may be catastrophic and must be controlled to either eliminate or minimise the risk.

Any activity involving hot work must be fully risk assessed by a competent person prior to the commencement of works.

A safe system of work must also be developed and implemented on site.

The risk assessment must be site specific and not generic.
