Fire extinguishers are critical safety tools designed to control incipient-stage fires and provide a means of escape during emergencies. However, these lifesaving devices can only fulfill their purpose if they are in proper working condition. Neglecting fire extinguisher maintenance can lead to malfunctions or failures in critical moments, increasing the risk of injuries and incidents.
We’ll explore the common issues that can arise with fire extinguishers and share best practices to ensure they are always ready to perform when needed.
Common Issues with Fire Extinguishers
- Rust and Leaks
The bottoms of fire extinguisher bottles are particularly susceptible to rust. Over time, rust can lead to leaks, compromising the extinguisher’s effectiveness. - Clogged Hoses
Partial deployment of a fire extinguisher can leave residual extinguishing agent in the hose, which can harden and create a clog over time. - Pressure Loss
Partial deployment often results in a gradual loss of pressure, rendering the extinguisher ineffective. - Seal and Gasket Deterioration
Prolonged periods of non-use can cause seals and gaskets to degrade, leading to potential malfunctions. - Environmental Damage
Exposure to harsh environmental conditions—such as extreme temperatures or moisture—can damage fire extinguishers, resulting in pressure loss or mechanical failure.
Best Practices for Fire Extinguisher Maintenance
To prevent these common issues, follow these essential maintenance and inspection guidelines:
- Inspect Before Starting Work
Conduct a quick inspection of all fire extinguishers before beginning any work tasks. - Perform Monthly Inspections
Schedule and document monthly checks to confirm that fire extinguishers are in good condition and ready for use. - Annual Professional Servicing
Have all fire extinguishers inspected and serviced by a certified third-party professional each year. - Proper Storage
Store extinguishers in dry, stable environments, away from extreme temperatures and wet or metal surfaces, to prevent rust and pressure loss. - Replace After Partial Deployment
Any extinguisher that has been partially deployed should be immediately replaced or recharged to restore full functionality. - Check Safety Pins
Ensure safety pins are securely in place to prevent accidental discharge.
What to Do After Partial Deployment
If an employee partially deploys a fire extinguisher, it is critical to:
- Remove the extinguisher from service immediately.
- Notify the appropriate personnel for replacement or recharging.
- Never reuse a partially deployed extinguisher without servicing it first.
Key Inspection Points
During routine inspections, look for the following:
- Intact and undamaged safety pins.
- Proper pressure levels, as indicated on the gauge.
- Clear, unobstructed hoses free of debris or residue.
- Signs of rust, corrosion, or physical damage to the extinguisher shell.
- An up-to-date service tag from a licensed professional.
Conclusion
Fire extinguishers are often overlooked until they are needed in an emergency. However, regular maintenance, inspections, and proper storage ensure they work as intended. Addressing common issues and adhering to best practices can help protect lives and property while ensuring compliance with safety standards.
Take the time to inspect your fire extinguishers regularly—because, in an emergency, preparation can make all the difference.
