6 Common Causes of Fire in Industrial Facilities and How to Prevent Them

Industrial facilities operate with complex systems, heavy machinery, and electrical networks while also handling hazardous materials, fuels, and waste products that significantly increase fire risk.

Across manufacturing plants, warehouses, refineries, power stations, and processing units, fire incidents continue to cause injuries, shutdowns, equipment damage, and financial losses.

Let’s explore the common causes of fire in industrial facilities and how Newtex Industries plays an important role in preventing industries from fire. 

What Are the Most Common Causes of Industrial Fires?

Fires in industrial facilities can start from multiple sources, including electrical issues, sparks from welding or cutting, flammable chemicals, dust buildup, equipment overheating, and unsafe human actions. Let’s explore in detail:

1. Hot Work Activities

Hot work includes welding, cutting, brazing, grinding, and soldering. These activities generate sparks, molten metal, and high surface temperatures.

Fires often occur when sparks move beyond the work area and come into contact with combustible materials such as cardboard, dust, insulation, chemicals, or flammable liquids. Sometimes materials stay hot even though you don’t see flames, and they can catch fire hours later.

2. Electrical Faults and Power System Failures

Industries rely on electrical power to operate machinery, lighting systems, control panels, heating equipment, and automation processes. When electrical systems are overloaded or poorly maintained, they can generate heat, sparks, or arcing that ignite nearby materials.

Damaged wiring, loose connections, overloaded circuits, outdated panels, and improper grounding cause typical electrical-related fires. In many cases, fires start inside electrical enclosures and spread before they are detected.

3. Flammable Liquids, Gases, and Chemicals

Some industries store and use flammable liquids, gases, and chemicals such as fuels, solvents, oils, adhesives, and process chemicals. Improper handling increases fire risk through leaks, spills, vapor buildup, static electricity, or contact with ignition sources. Once ignited, chemical fires spread rapidly and are difficult to control.

4. Combustible Dust Accumulation

Combustible dust is a hidden but dangerous fire hazard. Dust from materials such as wood, grain, sugar, metal, plastic, and coal can ignite or explode under the right conditions.

When dust builds up on surfaces or floats in the air, even a small spark or hot equipment can start a fire or explosion. Many serious industrial fires have happened because dust was not properly controlled.

5. Poor Equipment Maintenance and Overheating

Industrial equipment operates under continuous stress, high loads, and elevated temperatures. When machines are not properly maintained, friction, wear, and mechanical failure can generate excessive heat. 

Overheated motors, bearings, conveyors, and compressors can ignite nearby combustible materials or fail suddenly.

Best Practices:

• Follow preventive and predictive maintenance schedules

• Monitor temperature, vibration, and performance indicators

• Replace worn parts before failure occurs

• Keep equipment clean and well-lubricated

• Install fire-resistant barriers near high-temperature machinery

6. Human Behaviour and Unsafe Practices

Despite safety systems and automation, human behavior can still lead to fires. Actions such as improper storage of flammable materials, smoking in restricted areas, bypassing safety devices, and ignoring early warning signs contribute significantly. 

Note: To further reduce fire risks in your facility, Newtex Industries offers a wide range of high-temperature textiles, including fabrics, safety apparel, and fire containment covers for batteries & vehicles.

Fires in industrial facilities can result from a wide range of factors, including electrical faults, hot work, flammable materials, dust accumulation, equipment failure, and human error. Understanding these hazards and implementing targeted prevention measures is essential for protecting workers, equipment, and operations. 

Regular inspections, proper maintenance, safe handling of materials, housekeeping, and adherence to safety procedures significantly reduce the risk of fire. By staying vigilant and proactive, industries can create safer workplaces and minimize the financial, operational, and human costs associated with fire incidents.
