Inspection

Inspector Detail

Common issues

  • Unit carried past its manufacturer-marked expiry date without replacement
  • Casing corrosion or cracking from stowage in a damp or salt-laden locker
  • Striker/ignition cap failure from moisture ingress
  • Faded or illegible expiry marking making age verification difficult
  • Missing or damaged operating instructions printed on the casing
  • Poor stowage - unsecured, exposed to direct sunlight or heat sources - accelerating degradation
  • Buoyant body damage preventing correct floating orientation when deployed

Inspection checklist

  • Check manufacture and expiry date marked on each individual unit
  • Visual check of the casing for corrosion, cracks, or dents
  • Confirm the firing cap/striker mechanism is undamaged and dry
  • Confirm unit count matches the SOLAS muster requirement for that stowage position
  • Check the stowage location is dry, ventilated, and the units are secured against movement
  • Verify the printed operating instructions on the unit are legible
  • Confirm the buoyant body is intact with no puncture affecting flotation
  • Cross-check against the ship's pyrotechnics register/inventory log
  • Confirm replacement stock is ordered ahead of the earliest expiry date in the locker

Service intervals

Expiry-driven replacementreplace before the date printed on the individual unit - commonly around 3 years from manufacture for this class of SOLAS pyrotechnic signal, but always go by the marked date, not a rule of thumb
Locker/stowage condition checkat each routine lifesaving appliance inspection, commonly monthly
Full pyrotechnics inventory reconciliationat the annual LSA/safety equipment survey

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

Critical spares

  • Full replacement units of the same SOLAS/LSA Code approved type and pack size
  • Spare units held in the SOLAS-required minimum quantity for the stowage position (bridge, lifeboat, or liferaft as applicable)
  • Manufacturer's replacement stock sourced with matching type-approval documentation
  • Waterproof stowage bag or canister if original packaging is damaged
  • Updated inventory/expiry labels for the storage locker

Safety

  • Pyrotechnic composition is a fire and burn hazard - never open, dismantle, or expose the unit to heat or flame
  • Expired units must go through an approved hazardous-materials disposal route, never into general ship's waste
  • Handle strictly per the printed operating instructions - incorrect grip or ignition technique can cause burns
  • Keep stock away from accommodation heat sources and direct sunlight to reduce risk of accidental initiation

Class survey

Checked at each annual Safety Equipment/LSA survey against the ship's Safety Equipment Certificate inventory; surveyors verify quantity, correct stowage position, and that no unit is past its marked expiry date - expired stock found aboard is typically treated as a non-conformity.

Estimated lifetime: Not applicable in running hours - this is a single-use expendable pyrotechnic signal. The replacement driver is the manufacturer-marked expiry date, commonly around 3 years from manufacture for this class of device, not hours in service.
