Fire extinguishers are essential safety devices in any building, but they only work effectively if properly maintained. Regular Fire Extinguisher Service is not just good practice—it’s often legally required and crucial for ensuring your equipment functions correctly in an emergency. This article outlines the different types of fire extinguishers and the required service schedules to keep them in optimal working order.
Types of Fire Extinguishers and Their Service Needs
There are two primary types of fire extinguishers:
1. Stored Pressure Fire Extinguishers: These extinguishers contain the extinguishing agent and a pressurizing agent, like nitrogen or dry air, within the same cylinder. A pressure gauge indicates whether the extinguisher is adequately charged.
2. Cartridge-Operated Fire Extinguishers: These extinguishers store the extinguishing agent separately from the pressurizing agent (carbon dioxide) which is housed in a separate cartridge. Activating the extinguisher pierces the cartridge, releasing the pressurizing agent.
Fire Extinguisher Service Requirements: Basic and Advanced
Both types of fire extinguishers require regular fire extinguisher service, typically categorized as basic and advanced inspections.
Basic Fire Extinguisher Service: Annual Inspections
The National Fire Protection Agency (NFPA) mandates annual fire extinguisher inspections. This basic service includes:
- Visual Inspection: Checking for external damage, corrosion, and ensuring the safety seals are intact. Damaged extinguishers should be removed from service immediately.
- Check for Usage: Confirming the extinguisher hasn’t been used. Discharged or partially discharged extinguishers must be recharged or replaced.
- Hose Inspection: Examining the hose for blockages, cracks, or damage.
- Pressure Gauge Check (Stored Pressure Only): Verifying that the pressure gauge reading falls within the acceptable range. Weighing the extinguisher is only necessary after recharging a stored pressure unit.
Advanced Fire Extinguisher Service: Six-Year and Twelve-Year Inspections
Beyond the annual inspection, more thorough examinations are required at longer intervals:
Stored Pressure Extinguishers: Every six years, these extinguishers undergo an advanced inspection, including:
- Internal Inspection: The extinguisher is disassembled, and the cylinder’s interior is examined for corrosion or damage.
- Emptying and Refilling: The extinguishing agent is emptied, the cylinder inspected, and then refilled with the correct agent.
- Reassembly and Repressurization: The extinguisher is reassembled and repressurized to the proper level.
Cartridge-Operated Extinguishers: These extinguishers require a similar internal inspection and hydro testing every twelve years. This involves:
- Internal Inspection and Cartridge Check: Similar to the six-year inspection for stored pressure units, the extinguisher is disassembled, inspected, and the cartridge is checked for damage and accurate information (manufacturer, date, CO2 weight).
- Hydrostatic Testing: The cylinder is subjected to pressurized water testing to ensure its structural integrity.
The Importance of Professional Fire Extinguisher Service
Professional fire extinguisher service ensures that your equipment meets safety standards and will function as intended in a fire emergency. Neglecting required maintenance can lead to equipment failure, putting lives and property at risk. Furthermore, regular service ensures compliance with fire codes and insurance requirements.
Conclusion: Prioritize Fire Safety with Regular Maintenance
Fire extinguisher service is a critical component of fire safety. By adhering to the recommended inspection and maintenance schedules, you can significantly increase the chances that your fire extinguishers will operate effectively when needed most. Contact a qualified fire protection company to schedule your fire extinguisher service and ensure the safety of your building and its occupants.
