Fire Extinguisher: lifespan, maintenance and replacement

Typical lifespan: 5–12 years (about 12 years).

Maintenance schedule

• Check pressure gauge (should be in green zone) — Monthly
• Inspect for damage or corrosion — Every 6 months
• Inspect using the manufacturer’s instructions; do not shake unless directed — Monthly
• Arrange professional extinguisher inspection — Per manufacturer & applicable rules
• Have a qualified service company determine testing or replacement — Model/type-specific schedule

Signs it needs replacing

• Damaged hose or nozzle
• Corroded or dented cylinder
• Missing pin or tamper seal
• Extinguisher has been discharged (even partially)

Tips

Choose an extinguisher suited to the hazard and follow its instructions. Attempt only a small, contained fire with a clear escape route; evacuate and call emergency services if it spreads or you are unsure. Any discharge requires replacement or professional recharge before reuse. Never use water on a grease or energized electrical fire.
