Aerosol Fire Suppression Protected Area Sign

Aerosol Fire Suppression Protected Area Sign – FS0258

This aerosol fire suppression protected area sign shows a single aerosol generator unit beneath the word “Aerosol”, identifying a compartment protected by a fixed aerosol fire-extinguishing system. Unlike the cylinder battery sign fitted at the unit itself, this protected area sign is posted at the entrance to the space the system covers, so crew and visitors know before entering that an automatic aerosol release could occur without warning.

Fixed aerosol systems discharge a fine solid-particle aerosol that displaces oxygen in the same general way as CO2, so a space marked with this aerosol fire suppression protected area sign must be evacuated immediately on alarm and must not be re-entered until the space has been ventilated and declared safe. The sign is typically paired with an audible and visual pre-discharge alarm at the same entrance.

Where this sign is used

The aerosol fire suppression protected area sign is fitted on or beside every access door, hatch, or ventilation opening leading into the protected compartment, which is commonly a machinery space, pump room, or enclosed cargo hold. For the sign fitted directly on the cylinder bank supplying the system, see our aerosol fire suppression cylinder battery sign.

Fitting this protected area sign is straightforward: the photoluminescent film is self-adhesive and applies directly to the door, hatch coaming, or adjacent bulkhead after the surface is cleaned and dried. No drilling or mechanical fixing is required, and the sign is sized to remain legible from typical approach distances at every entrance to the space.

Maintaining the aerosol fire suppression protected area sign

New crew joining a vessel should be shown the location of each aerosol fire suppression protected area sign during their familiarisation rounds, since the evacuation response it calls for differs from the response to a standard fire alarm.

During routine fire rounds, crew should confirm that a sign is present and legible at every entrance to a space protected by an aerosol system, including any secondary hatches or ventilation access points that might otherwise be overlooked. Because photoluminescent film only charges under normal lighting, the sign needs to sit clear of shadows cast by fittings, ducting, or structural members so it can build and hold its charge for emergency conditions.

Vessels undergoing fire safety surveys are typically asked to show that every protected space is correctly marked at all points of entry, and that crew working in or near the area understand the evacuation procedure the sign implies. Keep a spare aerosol fire suppression protected area sign on hand alongside other fire control plan signage, so any missing or damaged sign can be replaced quickly, well before the surveyor arrives.

This sign is supplied as a durable, adhesive-backed marker sized to sit cleanly on standard steel doors, hatches, and bulkhead surrounds throughout machinery and service areas.

Order the correct aerosol fire suppression protected area sign for every entrance shown on the fire control plan before the next survey, and keep the pictogram consistent across sister vessels sharing the same system layout.

Because crew unfamiliar with a vessel may not recognise the aerosol pictogram on sight, inductions and safety briefings should point out exactly where each aerosol fire suppression protected area sign is posted, alongside the location of the corresponding release controls and alarms.
