LIFECYCLE VISUALIZATION

“`
EQUIPMENT LIFECYCLE PHASES
═══════════════════════════════════════════════════════════════

PHASE 1: Initial Service (Year 0)
└─ Installation & commissioning

PHASE 2: Inspection Era (Years 1-5)
├─ Monthly visual inspections
├─ Annual maintenance
└─ Potential fire extinguisher recharge needs

PHASE 3: Internal Examination (Year 6)
├─ Complete disassembly
├─ Internal vessel inspection
└─ Component replacement

PHASE 4: Testing Era (Years 5-12 depending on type)
├─ Hydrostatic testing
├─ Pass/fail determination
└─ Fire extinguisher recharge after testing

PHASE 5: Replacement Decision (Year 10-15+)
└─ Equipment lifecycle assessment
“`

Each phase requires specific maintenance practices. Commercial buildings benefit from understanding complete lifecycle rather than viewing maintenance as isolated events.

BEST PRACTICE 1 → MONTHLY INSPECTION SYSTEMATIZATION

The Foundation Protocol

NFPA 10 Section 7.2 requires monthly inspections. Best practice transforms requirement into systematic reliability verification.

—

Establishing Inspection Consistency

Standard approach:

• Someone checks extinguishers monthly
• Inconsistent thoroughness
• Variable documentation
• Gaps occasionally occur

Best practice approach:

SYSTEMATIC INSPECTION PROGRAM

Fixed schedule implementation:
□ Same day each month (e.g., first Monday)
□ Backup date designated (holiday/closure accommodation)
□ Calendar blocking prevents conflicts
□ Automated reminders ensure execution

Designated inspector accountability:
□ Primary inspector assigned
□ Backup inspector trained
□ Responsibilities documented
□ Performance accountability established

Route optimization:
□ Logical inspection sequence created
□ Equipment grouped by location
□ Efficient pathway minimizes time
□ All units included systematically

—

Complete Criteria Examination

NFPA 10 Section 7.2.1.1 eight mandatory criteria:

“`
CRITERION 1 → Location Verification
├─ Unit in designated place
├─ Mounting secure
└─ No unauthorized movement

CRITERION 2 → Accessibility Assessment
├─ No obstructions present
├─ Clear access path
└─ Signage visible

CRITERION 3 → Operating Instructions
├─ Labels legible
├─ Instructions visible
└─ Facing outward

CRITERION 4 → Pressure Gauge Reading
├─ Needle in operable range
├─ Gauge functional
└─ Response to tap test

CRITERION 5 → Fullness Verification
├─ Hefting weight appropriate
├─ Agent loss suspected → weigh
└─ CO2 units → always weigh

CRITERION 6 → Physical Condition
├─ No damage visible
├─ No corrosion present
└─ No leakage evidence

CRITERION 7 → Hose & Nozzle
├─ Attached securely
├─ No cracks/deterioration
└─ Discharge opening clear

CRITERION 8 → Seals & Indicators
├─ Pin present, intact
├─ Seal unbroken
└─ No tampering evidence
“`

Best practice: Digital checklist ensures all criteria examined every inspection, eliminating human oversight.

• Hydrostatic testing completed

Proactive recharge considerations:

• Pressure at low end of operable range
• Slow pressure loss history
• Equipment approaching six-year examination
• Agent age exceeding manufacturer recommendation
• Environmental exposure concerns

Best practice: Fire extinguisher recharge performed whenever pressure questionable rather than waiting for complete failure.

—

Proper Service Tag Application

NFPA 10 Section 7.3.4 service tag requirements:

Required information:

1. Month and year service performed

2. Name/initials of person performing service

3. Name of servicing agency

Best practice tag includes additional information:

□ Service type performed (maintenance/recharge/testing)
□ Next service due date
□ QR code linking to digital service record
□ 48Fire contact information

Tag durability considerations:
□ Weather-resistant materials (outdoor units)
□ Secure attachment method
□ Legibility preservation
□ Tamper-evident features

—

BEST PRACTICE 3 → SIX-YEAR INTERNAL EXAMINATION

Mandatory recharge situations:

• Gauge indicates low/no pressure
• Any amount discharged (even small test)
• Broken seal (regardless of reason)
• Failed leak test
• Slow pressure loss detected
• Post-testing restoration
• Post-six-year examination

Proactive recharge indicators:

• Pressure at low end of range (but still operable)
