Fire Resisting Ceiling Panel - Type "T25DXY" (T25DXY')

Common issues

• Panel joint or sealant degradation compromising fire integrity
• Unapproved penetrations (cables, pipes) routed through the panel without proper fire-stopping
• Corrosion of panel core or facing material in wet spaces
• Loose or damaged panel fixings reducing the structural integrity of the division
• Delamination of the facing material
• Unauthorized modification or removal of panel sections during outfitting or repair work

Inspection checklist

• Visual inspection for damage, delamination, corrosion or missing fixings
• Check that all penetrations (cables, pipes, ducts) have approved fire-stopping maintaining the B-class rating
• Verify panel type/identification marking is still legible
• Check joints and seals for gaps
• Confirm no unapproved modifications have been made since the last survey
• Cross-check the panel arrangement against the approved fire control plan

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

• Matching approved B-class panel sections/sheets of the same type and thickness
• Approved fire-stopping/sealing material for penetrations
• Panel fixing/fastener sets

Safety

• Any breach or unapproved penetration compromises the fire division and can allow fire/smoke spread between compartments
• Do not substitute non-approved materials for repairs - this invalidates the B-class rating
• The panel contributes to protection of means of escape - its integrity is life-safety critical

Class survey

Note on this catalogue entry: it is listed under 'CO2 Fixed System', but this item (UK MCA-approved, certificate LR23100952UKMB) is a B-class fire-resisting ceiling panel - passive fire protection, not an active CO2 extinguishing system. The content above addresses the actual product. Survey checks the fire control plan against the as-fitted divisions, confirms no unauthorized penetrations, and verifies the type-approval marking remains valid and legible.

Estimated lifetime: Passive fire divisions are assessed on condition rather than hours in service; a well-maintained panel typically remains in service for the vessel's life provided the division is never breached or damaged without approved repair.
