Hot Work

What is considered “Hot Work”?

Any operation that involves open flames or sparks or produces sufficient heat to ignite flammable or combustible materials is considered “Hot Work”. Also, any work that generates enough dust to harm or negatively impact the fire protection system is also subject to Hot Work protocols.

Examples of Hot Work include: cutting, welding, soldering, brazing, grinding, adhesive bonding, thermal spraying thawing pipes, and applying roof covering and sealing plastic shrink-wrap by torch.

Hot Work Permits

A permit is required for each job in a given area during a specified period of time. The permit application must be submitted 48 hours prior to the anticipated start of work.

Hot Work Permit Application

The person planning to perform the hot work (i.e. the Hot Worker) completes part 1 & 2 of the application before submitting to a Manager or Supervisor. The Manager/Supervisor then co-ordinates with the FMP Service Centre to arrange for fire system isolation and finalizes permit process.

Hot Worker Responsibilities

The Hot Worker is responsible for completing the Hot Work Inspection Checklist before beginning work and everyday subsequently.  The completed Inspection Checklist must be displayed in the work area.

When all work is complete or at the end of the permit window, the Hot Worker is responsible for notifying the FMP Service Center and handing-in the inspection checklists and Hot Work permit.

This procedure aims to prevent disruptions to the fire protection systems triggered by accidental incidents as well as minimizing risk to building occupants. Consult the detailed workflow of the Hot Work protocols for more information.
