Close This Door at Night Sign

Close This Door at Night Sign – MS0047

The Close This Door at Night Sign identifies a door that must be closed during night hours as part of the vessel’s security, noise-control, or fire-zone discipline. This mandatory sign reminds crew and passengers to secure the door once darkness falls, whether it protects a quiet accommodation area, a restricted space, or a boundary that should not be left open overnight.

Manufactured from durable photoluminescent material, MS0047 continues to glow after the ship’s main lighting fails, keeping the instruction legible during a blackout or a night-time transit through the space. Its blue circular mandatory-action field with bold white text is designed for instant recognition in accommodation passageways and other areas where a night-closing routine applies, supporting the IMO’s emphasis on clear, standardised shipboard signage.

Why the Close This Door at Night Instruction Matters

A door left open overnight can undermine security arrangements, allow noise to disturb resting crew, or compromise a fire or watertight boundary at a time when fewer people are moving through the space to notice. A clear, standardised night-closing instruction reinforces correct end-of-day practice, helping ensure the door is secured as part of the crew’s routine rounds and handover procedures.

Compliance and Certification

MS0047 is produced to support compliance with the vessel’s Safety Management System under the ISM Code, with door discipline generally supporting the structural fire protection and security provisions referenced across SOLAS and ISPS Code frameworks. For further detail on SOLAS requirements, see the IMO’s SOLAS convention overview. Maintaining clear, legible signage on every such door supports a positive outcome at Port State Control and flag-state inspections.

Installation Recommendations

Install MS0047 directly on or immediately adjacent to the door at eye level, positioned so anyone passing sees it clearly, particularly during evening and night watch rounds. Mount on a flat, stable surface using marine-grade adhesive or corrosion-resistant fasteners suited to the surrounding finish. Reinforce the instruction through watch handover procedures and nightly closing routines.
