MBK13-060AF-BSI – 6 Litre AFFF 3% Foam Fire Extinguisher.

Common issues

• Loss of internal pressure over time (stored-pressure type) requiring recharge
• Foam concentrate degradation or settling if servicing intervals are not observed
• Corrosion of the cylinder body, especially in salt-laden engine room or deck environments
• Damaged or seized discharge valve/hose preventing operation
• Missing or illegible service tag/inspection date
• Mounting location blocking quick access

Inspection checklist

• Check the pressure gauge reading is within the operating band (stored-pressure units)
• Visual check for corrosion, dents, or damage to the cylinder
• Verify the safety pin and tamper seal are intact
• Confirm the extinguisher is in its designated, unobstructed location with correct signage
• Check the discharge hose/nozzle for cracks or blockage
• Verify the service/inspection tag is current and legible

Service intervals

Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.

Typical wear limits

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

• Replacement AFFF 3% foam concentrate charge, correct type
• Discharge hose/nozzle assembly
• Safety pin and tamper seal set
• Pressure gauge, for stored-pressure units

Safety

• A stored-pressure extinguisher is a pressure vessel - do not attempt to open or service beyond routine visual checks without proper training
• AFFF foam concentrate handling should follow current environmental/disposal rules; some AFFF formulations are subject to PFAS-related restrictions - check the specific product's current regulatory status
• Confirm the extinguisher type is correct for the fire risk at its mounting location before relying on it

Class survey

Note: the catalog type recorded for this entry ('CO2 Fixed System (Engine Room + Cargo)') does not match the actual product, which is a portable AFFF foam extinguisher - the notes above address the portable unit. Surveyors checking portable fire-fighting equipment verify current service tags, correct type and quantity against the fire control plan, unobstructed access, and that servicing/hydrostatic test intervals have not been exceeded.

Estimated lifetime: Portable foam extinguishers of this type are commonly given a service life in the order of 10-20 years by the maker, subject to passing periodic hydrostatic testing and internal examination - confirm the specific limit on Mobiak's documentation and the applicable flag/class requirement
