HOT WORK RISKS: WHY ONE SPARK CAN BECOME A MAJOR BUSINESS LOSS

Compiled by Schalk W. Lubbe

Most businesses don’t think twice about hot work activities.

Welding, grinding, cutting, soldering, and similar maintenance tasks happen daily in workshops, factories, warehouses, and commercial facilities. Because these jobs are routine, the fire risk surrounding them is often underestimated.

The problem is that hot work creates one of the most common ignition sources responsible for serious industrial and commercial fires.

A single spark can travel further than most people expect. In the wrong environment, that spark can ignite combustible materials within seconds. Dust, packaging, insulation, chemicals, vapours, and even hidden materials behind walls or ceilings can all contribute to rapid fire spread.

What makes hot work especially dangerous is that fires do not always start immediately.

In many cases, sparks smoulder unnoticed before developing into a fire later in the day or even after staff have left the premises. By the time smoke or flames are visible, the damage is already significant.

This is why proper hot work controls matter.

Many businesses still rely on informal safety practices or outdated permit systems that fail to properly evaluate the actual risk involved. Fire extinguishers alone are not enough protection if the surrounding risk has not been assessed correctly.

An effective hot work management process should include:

Proper risk assessments before work starts

Identification of combustible materials nearby

Fire watch procedures during and after work

Suitable fire protection systems

Trained personnel and supervision

Clear permit-to-work controls

Hot work safety is not just about compliance. It is about preventing operational disruption, protecting staff, and reducing the potential for severe financial loss.

At Collaborative Risk Applications, we help businesses identify and manage fire risks associated with hot work activities through practical fire risk engineering and protection strategies designed around real operational conditions.

Because when fire prevention is treated seriously before work begins, businesses reduce the chance of facing major losses later.
