Fire Control Plan: SOLAS II-2/15, IMO Res. A.1116(30) & ISO Signs Guide

A ship's Fire Control Plan is not merely an engineering drawing; it is a legally binding operational document that coordinates shipboard firefighting strategy and informs emergency services during a casualty. Under SOLAS Chapter II-2 Regulation 15.2.4, general arrangement plans must be permanently exhibited for the guidance of the ship's officers in prominent, illuminated locations (such as the navigation bridge, ship's office, engine control room, and main alleyways).

Alternatively, at the discretion of the flag Administration, the detailed fire safety information may be presented in a booklet form, provided a copy is supplied to each officer and one copy is accessible at all times on board in an approved position. The plan must detail the exact positions of structural boundaries, extinguishing appliances, detection zones, and remote shutdown controls:

For decades, maritime safety signage relied on IMO Resolution A.760(18) symbols. However, differences between civil building codes and maritime symbols created dangerous confusion during emergencies. To eliminate discrepancies, the IMO Assembly adopted Resolution A.1116(30) (Escape Route Signs and Equipment Location Markings):

Mixed Standards Hazard: A common Port State Control detention trap occurs when existing vessels undergo partial signage replacement and mix legacy A.760(18) symbols with new A.1116(30) / ISO 7010 signs along the same escape trunk. If signage is renewed, the entire escape route or compartment must follow a single consistent standard, and the shipboard Fire Control Plan legend must accurately reflect the specific symbols installed.

When a ship catches fire in port, municipal shore firefighters board an unfamiliar vessel in thick smoke and intense heat. Under SOLAS Regulation II-2/15.2.4.2 and IMO MSC/Circ.451, a duplicate set of Fire Control Plans or fire safety booklets must be permanently stored in a prominently marked weathertight enclosure outside the deckhouse:

• Physical Construction & Location: Typically a cylindrical metal or heavy-duty plastic container painted bright signal red, mounted on an exterior bulkhead immediately adjacent to the primary gangway or embarkation access point.
• Prominent Marking: Marked clearly with the ISO 17631 / A.1116(30) graphical symbol for "Fire Control Plan" (a red drawing icon depicting a ship profile and fire axes). Lettering "FIRE PLANS" should be in contrasting white.
• Weathertight Integrity: The canister lid or door must be fitted with an intact neoprene or rubber gasket to prevent rainwater, salt spray, and atmospheric moisture from soaking and destroying the paper plans inside.
• Tool-Free Access: The container MUST be capable of being opened easily and immediately by hand without keys, padlocks, wrenches, or special tools. Locking the external fire plan cylinder is a major detention item.
• Up-to-Date Contents: The plan inside must be identical to the wheelhouse plan, reflecting all recent alterations, current crew muster list roles, dangerous goods manifests (if in port), and stability data summaries.

In a major fire, thermal buoyancy causes superheated toxic smoke to fill the upper 1.5 to 2.0 metres of corridors and stairwells, blinding standard ceiling-mounted emergency lights and rendering bulkhead signs invisible. Low-Location Lighting (LLL) ensures that evacuees crawling beneath the smoke layer can trace an unbroken illuminated path to safety:

• Mandatory Carriage: Required on all passenger ships carrying more than 36 passengers (SOLAS II-2/13.3.2.5.1) and all ro-ro passenger ships.
• Installation Geometry: Continuous photoluminescent strip or electrically powered light track fitted not more than 0.3 metres above the deck along all escape corridors, stairways, and exits.
• Door & Exit Marking: Fire exits, escape hatch ladders, and emergency doors must be outlined with LLL markings, with door handles marked to indicate opening mechanisms.
• Luminance Performance (FSS Code Ch. 11 & Res. A.752(18)): Photoluminescent strips must maintain >= 15 mcd/m² after 10 minutes of darkness, and >= 2 mcd/m² after 60 minutes.
• Annual Survey & Certification: Annual measurement of photoluminescent luminance must be conducted using a calibrated photometer by an approved service supplier and kept with Class survey records.

Port State Control inspectors scrutinize Fire Control Plans under Paris MoU, Tokyo MOU, and USCG deficiency code 07105 (Fire safety documentation). Any discrepancy between the drawing and shipboard reality raises immediate suspicions regarding safety management system (SMS) integrity:

• Damper Tagging & Plan Cross-Checks: Every fire damper on deck must carry a physical, weather-resistant label (e.g. "FD-ENG-01") that matches the plan legend exactly. Numbering errors or unlabelled dampers are universally penalized.
• Operational Testing of Dampers: During PSC inspections, officers will be required to operate dampers, verifying free fall of counterweights, intact fusible links, and full internal flap closure.
• Remote Fuel Stops & Quick-Closing Valves: Verify that emergency stop stations (boiler trips, fuel transfer pump stops, lub oil pump trips, quick-closing valve pull handles) match the symbols on the Fire Control Plan.
• International Shore Connection: Ensure the international shore connection flange, bolts, gasket, and spanners are stowed in the exact locker designated on the plan.
• Damp or Illegible External Plans: Check the external fire plan cylinder weekly. Wet, stuck, or faded plans represent an immediate Form B deficiency and undermine port safety coordination.
