Imagine a factory for producing textiles located in industrial zones like Maharashtra or Tamil Nadu. The factory contains numerous rows of automated looms running round the clock and producing fine cotton lint, which accumulates silently on the electrical connections and the hot parts of machines. In the middle of the night, there is a spark due to some dangling wires. In a few moments, the dry lint catches fire and spreads rapidly on the storage racks.
In an industrial setting, even a minor ignition source can develop into a serious fire within seconds.
A fire risk assessment helps identify vulnerabilities, establish appropriate controls, and strengthen proactive fire safety practices.
What Is a Fire Risk Assessment?
Fire risk assessment is a systematic examination of your industrial premises. This involves the physical structure of your plant, chemical storage, electrical installations, and activities by employees on a daily basis to establish possible risks.
The objective is to identify fire hazards, determine who may be at risk, and establish appropriate measures to prevent or limit fire.
5 Steps of Industrial Fire Risk Assessment
A proper fire risk assessment can be carried out through several structured steps.
Step 1: Fire Hazard Identification
It begins with a walk-through of all the areas of the industrial site to identify hazards present.
A. Sources of Ignition
Identify potential sources of heat, sparks or flames, including:
- Damaged wiring, overloaded circuits, loose connections and deteriorated motor insulation.
- High-risk activities such as welding, cutting and grinding, particularly where required hot-work controls or permits are not in place.
- Friction between mechanical parts, such as an unlubricated conveyor belt or overheated bearings.
- Heated surfaces like steam pipes, boilers, and ovens.
- Build-up of static electricity while handling flammable liquids.
B. Fuel Sources
Identify materials that can readily ignite or contribute to fire spread, including:
- Flammable liquids and solvents (thinner, paint, diesel fuel, alcohol solvents).
- LPG, natural gas or hydrogen systems, where applicable.
- Combustible solids such as cardboard boxes, wooden pallets, textile fibers, and plastic raw materials.
- Dusts formed from the processing of grains, wood grinding, or metal powders.
Step 2: Identify People at Risk
After identifying the hazards, determine which people may be affected in the event of a fire:
- Routine Floor Workers: Workers operating in higher-risk areas such as chemical processing or heat-treatment zones.
- Maintenance/Contract Workers: Maintenance and contract workers carrying out work in utility areas or performing hot-work activities.
- Visitors/Contractors: Persons who may be unaware of the site’s layout and evacuation routes.
- Vulnerable Workers: People who may require additional assistance during evacuation, including those with mobility limitations or those working in areas where alarms may be difficult to hear.
Step 3: Evaluate, Remove, and Control the Risks
Evaluate the likelihood of fire and the potential consequences, taking into account the existing controls. Eliminate hazards where reasonably practicable and introduce appropriate controls to reduce remaining risks.
A. Risk Elimination and Reduction
- Store flammable liquids in suitable, approved storage cabinets appropriate to the materials and applicable requirements.
- Bonding and grounding straps should be used during transfer of chemicals to avoid sparking due to static discharge.
- Carry out regular inspection and preventive maintenance of electrical distribution panels to identify loose connections, overheating and other defects.
B. Fire Detection and Protection Measures
Select appropriate fire detection and protection measures based on the identified hazards and applicable requirements:
- Detection & Alarm Mechanisms: Provide suitable fire detection and alarm systems based on the hazards, occupancy and characteristics of the facility.
- Fire Suppression Equipment: Provide suitable portable fire extinguishers based on the types of fire hazards identified and the applicable standards.
- Automatic Fire Protection Systems: Where required provide suitable automatic fire suppression based on the hazard, room type and applicable design requirements.
Step 4: Record Findings, Draft Evacuation Plans, and Train Personnel
List all identified hazards, control measures undertaken, and residual risks in the master risk register.
A. Preparing an Effective Evacuation Plan
An effective evacuation plan facilitates the orderly and safe evacuation of people in the case of an emergency:
- Unobstructed Exit: Keep all emergency routes clear from any kind of obstacles such as piled up boxes or equipment.
- Visible Exit Points: Provide battery-operated exit signs and illuminated emergency lighting through all the evacuation routes.
- Safe Gathering Areas: Provide designated assembly areas at a safe distance from the building and other potential hazards.
- Evacuation Supervisors: Assign responsible personnel to guide evacuation and support headcounts at designated assembly areas.
B. Human Preparedness and Training
Even if the most sophisticated safety equipment is available, it will not work properly without proper training. In combination with physical safety checks it will provide your employees with the knowledge about how to act in case of an emergency.
Employees should be trained to:
- Identify any potential fires in their routine work.
- Use fire extinguishers using the P.A.S.S. technique (pull, aim, squeeze, sweep).
- Evacuate in an orderly manner without panicking.
Step 5: Review and Update the Assessment Regularly
A fire risk assessment should be reviewed periodically and whenever significant changes affect fire risk, including:
- Installation of new machinery for production or high-voltage electrical switchgear.
- Introduction of new formulations, raw materials or processes.
- Changes in building structure.
- Following a fire, near miss or other incident that may indicate a change in fire risk.
Fire Risk Assessment Checklist for Industrial Operations
Use this practical matrix to audit risk factors across different industrial zones:
| Work Zone | Hazard Focus Areas | Recommended Prevention Controls |
|---|---|---|
| Chemical Storage | Volatile solvent vapours, static sparks, chemical reactions | Suitable electrical equipment, bonding/grounding, spill control |
| Electrical Rooms | Switchgear overloading, arc faults, loose cable connections | Thermal imaging, housekeeping, routine inspection and maintenance |
| Production Floor | Overheating motors, friction sparks, combustible dust | Preventive maintenance, dust control, hot-work permits |
| Warehouse Zone | High-density packaging, blocked aisles, battery charging | Safe stacking, clear access routes, designated battery-charging areas |
Common Mistakes in Industrial Fire Risk Assessments
- Failing to consider Human Behaviour: Fitting of fire doors without considering the practice of employees opening them using wooden wedges.
- Neglecting to Consider Maintenance Logs: Assuming hydrants and extinguishers function without checking maintenance records from the month before.
- Disregarding the Preparedness of Night Shifts: Conducting only daytime drills and never conducting night-time drills for preparedness.
- Considering Hardware Only: Depending on sprinklers without taking into account that early hazard detection is important.
