Common failures & inspection points

Pressure Gauge Verification

Verify pressure gauge needle is within green zone. Check for corrosion or damage to gauge glass/needle. Confirm pressure reading matches expected range per manufacturer specifications (typically 1-2 bar below minimum discharge pressure indicates need for servicing).

Physical Damage & Corrosion Assessment

Inspect body for dents, rust spots, leaks, bent handle, missing or damaged nameplate. Check hose/horn for cracks, kinks, blockage, or deterioration. Verify CO2 cartridge (powder/foam models) is not corroded and remains firmly secured. Examine CO2 horn/nozzle for ice buildup or operational obstructions.

Safety Pin & Discharge Mechanism

Confirm safety pin is intact and properly inserted through handle and discharge lever. Verify lever moves freely without sticking or obstruction. Check discharge nozzle (foam/powder) or horn (CO2) can rotate or aim freely. Test lever spring tension by light pressure - should resist but not be stuck.

Weight Verification & Content Integrity

Weigh extinguisher and compare to specification nameplate weight for full/loaded unit. For CO2 models, weight loss >5% from manufacture weight indicates potential leakage. For powder models (P-series), verify no settling/compaction by listening for powder movement when gently shaken. Foam models (E-series) must show full liquid level without separation.

Certification & Service Tag Validation

Verify current service tag/certificate dated within 12 months from certified service provider. Confirm MED (Marine Equipment Directive), PED (Pressure Equipment Directive), EN 3 or EN 866 certifications are visible on nameplate. Check hydrostatic test date for wheeled/larger units (P25/P50/E45A) - maximum 5-year intervals required per SOLAS. Verify manufacturer date code on body.
