What to Expect During a Professional Fire Extinguisher Service

—

YOUR SERVICE APPOINTMENT: WHAT ACTUALLY HAPPENS

Technician scheduled for Tuesday. What occurs during the visit?

Most facility managers never observe professional fire extinguisher service directly. Equipment gets serviced during normal operations. Technician arrives, works on extinguishers, leaves documentation. The process remains unclear.

Understanding professional fire extinguisher service helps facilities:

• Recognize quality service vs. inadequate work
• Prepare facilities appropriately
• Verify NFPA requirements satisfied
• Understand service value
• Identify substandard service

This article details actual professional fire extinguisher service from arrival through completion—procedures, timing, documentation, and NFPA 10 compliance elements.

• Stress indicators (dents, scratches, wear)
• Environmental exposure (fading, dirt, moisture)
• Tampering evidence (broken seals, missing pins)

—

Pressure Verification

Critical measurement per NFPA:

For stored pressure types:

Visual gauge assessment:

• Read directly with proper lighting
• Document zone (green/yellow/red)
• Photograph for records

Function verification:

• Tap gauge detecting stuck needles
• Observe needle response
• Document mechanical issues

Range verification:

• Confirm manufacturer specifications
• Green zone = operable range
• Yellow/red = immediate service needed

For CO2 types:

Weight verification required:

• Remove and weigh on calibrated scale
• Compare to specification weight
• Calculate acceptable range (±10% typical)
• Document actual vs. specification

Why verification matters:

Green gauge doesn’t definitively prove adequate pressure. Technicians verify:

• Gauge accuracy through calibrated equipment
• Gauge mechanical function (not stuck)
• Actual pressure/weight meets specifications

Common findings:

• Gauges stuck in green zone
• Faded gauges (unclear boundaries)
• Slow pressure loss beginning
• CO2 weight loss indicating leaks

Time per unit: 1-2 minutes

—

Seal and Tamper Indicator Check
