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).

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.

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.

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.

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.
