Hot Works Prohibited Sign

Hot Works Prohibited Sign

The Hot Works Prohibited Sign provides a clear visual instruction that hot work activities are prohibited in a particular area. Hot work can include activities such as welding, flame cutting, brazing, soldering and some grinding or cutting operations that produce heat, sparks or flame.

Featuring a red prohibition symbol and clear HOT WORKS PROHIBITED wording, the sign provides an easily recognised visual message for employees, contractors and visitors entering restricted work areas.

• Communicate restrictions to employees and contractors
• Support workplace hot work procedures
• Reduce the risk of prohibited ignition sources being introduced

Choosing the Right Sign Size

Choose the sign size according to its installation position and required viewing distance.

Smaller signs can be suitable when positioned directly beside pipework or at close-range access points. Larger signs provide increased visibility in larger industrial and processing environments.

Refer to our viewing-distance guide below for help selecting an appropriate size.

Related Hazards

• Sparks
• Open flames

Helps Comply With

Clear prohibition signage can form part of a workplace’s system for communicating hot work restrictions and site safety procedures.

A Hot Works Prohibited Sign does not replace a workplace risk assessment, hot work permit system or other required safety controls. Appropriate controls should be selected according to the work being undertaken and the hazards present at the site.
