IMO ‘A’ Self-Closing Watertight Fire Door Sign – FS0225
This ‘A’ self-closing watertight fire door sign, marked “WT” with a self-closing swing arrow, identifies a hinged fire door within an ‘A’ class fire division that closes automatically and carries a full watertight rating under SOLAS Chapter II-2. The self-closing mechanism drives the door shut after use, restoring both the fire division and the watertight boundary without relying on crew action.
A self-closing watertight fire door that is wedged or tied open loses its protective value at once – both fire integrity and the watertight seal are defeated the moment the door is held open. This sign reminds crew and passengers to let the door close fully and never obstruct its swing.
Where this sign is used
Self-closing watertight fire doors of this type are commonly fitted at main watertight subdivision boundaries that also form part of an ‘A’ class fire division, including engine room and machinery space bulkheads. This self-closing watertight fire door sign is mounted directly on or beside the door leaf so it is seen every time the door is passed through.
Regulatory context
Fire and watertight door classifications follow SOLAS Chapter II-2 and the SOLAS watertight subdivision requirements, which set the fire-resistance rating, self-closing requirement, and watertight standard for doors of this type. Surveyors checking every self-closing watertight fire door and its signage during inspections expect clear, photoluminescent identification at each opening.
Installing this self-closing watertight fire door sign is straightforward: the peel-and-stick backing adheres directly to the door leaf or adjacent bulkhead, and the photoluminescent film charges under normal lighting so the pictogram remains visible if power and lighting are lost.
