Common Mistakes While Using Fire Extinguishers

Fire extinguishers are widely installed in workplaces, commercial buildings, and industrial facilities.

However, during real emergencies, many extinguishers fail to control fires, not because of equipment failure, but due to human mistakes.

Fire emergencies create:

Panic
Confusion
Time pressure

In such conditions, people react instinctively instead of following correct procedures.

In many workplaces, extinguishers are installed for compliance, but practical training and real preparedness are ignored.

As a result, even available equipment becomes ineffective.

The Role of Human Behavior in Fire Emergencies

In real fire situations:

Stress affects decision-making
Memory of training reduces
Coordination becomes difficult
Fear delays action

Even trained workers can make mistakes under pressure.

This is why fire safety must focus not only on equipment, but also on behavior and practice.

Most Common Mistakes While Using Fire Extinguishers

Using the Wrong Type of Fire Extinguisher

This is one of the most dangerous errors.

Examples include:

Using water on electrical fires
Using CO₂ on deep-seated materials
Using foam on reactive metals

Consequences:

Fire intensifies
Risk of electric shock
Re-ignition occurs

How to Avoid

Clearly label extinguishers
Train workers on fire classes
Conduct practical drills

Not Pulling the Safety Pin

Under stress, people often forget basic steps.

Result:

Extinguisher does not operate
Time is lost
Fire spreads rapidly

How to Avoid

Teach the PASS method
Pull, Aim, Squeeze, Sweep
Conduct hands-on training

Standing at the Wrong Distance

Improper positioning reduces effectiveness.

Common errors:

Too close, leading to risk and poor control
Too far, causing ineffective discharge

Correct Practice

Maintain recommended distance
Aim at the base of the fire
Move forward gradually

Spraying Randomly Instead of Sweeping

Uncontrolled discharge leads to:

Wastage of extinguishing agent
Incomplete coverage
Fire spreading

Correct Practice

Sweep side to side
Start from nearest edge
Maintain steady pressure

Attempting to Fight Large Fires

Extinguishers are designed only for small fires.

Mistakes occur when people try to control:

Large flames
Rapidly spreading fires
Smoke-filled areas

Correct Decision

Evacuate immediately
Activate alarm
Call emergency services

Using Poorly Maintained Extinguishers

Common issues include:

Expired units
Low pressure
Blocked nozzles
Broken seals

These extinguishers fail during emergencies.

Prevention

Monthly inspection
Annual servicing
Immediate replacement of faulty units

Lack of Training and Confidence

Untrained workers:

Hesitate to act
Panic during emergencies
Misuse equipment

Solution

Conduct live demonstrations
Provide hands-on practice
Repeat training regularly

Ignoring Re-Ignition Risk

Some fires appear extinguished but restart due to:

Residual heat
Smoldering materials
Incomplete cooling

Best Practice

Monitor area after extinguishing
Ensure complete cooling
Do not leave immediately

Poor Placement of Fire Extinguishers

Even trained workers fail when extinguishers are:

Blocked
Hidden
Installed incorrectly

Correct Placement

Near exits
Clearly visible
Easily accessible

Treating Fire Safety as a Formality

In many workplaces:

Equipment is installed for audits
No real ownership exists
No follow-up is done

This leads to poor preparedness.

What Safety Officers Commonly Miss

In real workplaces, these gaps are often overlooked:

No practical extinguisher training
Workers unaware of fire classes
Poor placement and accessibility
Lack of inspection records
Overconfidence in equipment

These issues significantly reduce emergency response effectiveness.

Real Workplace Example

In an office environment, a small electrical fire occurred.

An employee used a water extinguisher.

This resulted in:

Increased risk due to electricity
Delay in proper response
Fire spreading to nearby equipment

The investigation showed lack of training and awareness.

The extinguisher was available, but used incorrectly.

Fire Extinguisher Usage Checklist

Before Emergency

Know extinguisher types
Identify fire risks
Ensure accessibility
Attend training sessions

During Emergency

Follow PASS method
Use correct extinguisher
Maintain safe distance
Keep exit behind you
Stop if fire grows

After Use

Monitor for re-ignition
Report incident
Replace used extinguisher

Practical Steps to Prevent Mistakes

Conduct regular fire drills
Provide hands-on training
Display fire class charts
Assign fire wardens
Review incidents and near-misses

Industry Guidance and Standards

According to the National Fire Protection Association, proper fire extinguisher use depends on correct selection, regular maintenance, and effective user training.

NFPA emphasizes:

Practical training
Awareness of fire classes
Proper maintenance
Integration with emergency response

Warning Signs of High Risk

Look for these indicators:

Workers unsure how to use extinguishers
No training records
Blocked equipment
Frequent misuse
Poor inspection practices

These signs indicate increased fire risk.

Conclusion

Fire extinguishers are effective only when used correctly.

Most failures during emergencies are not due to equipment defects, but due to human mistakes.

By improving:

Training
Awareness
Practice
Supervision

workplaces can significantly reduce fire risks.

Fire safety is not about having equipment.

It is about using it correctly when it matters most.
