Fixed Fire-Extinguishing Bottle Sign

Fixed Fire-Extinguishing Bottle Sign – FS0016

This IMO fire control sign identifies the location of a fixed fire-extinguishing bottle, shown in the pictogram as a round pressurised bottle on a mounting stand with flames rising beside it. The fixed fire-extinguishing bottle sign marks a single upright gas bottle feeding a fixed suppression system, distinguishing it from the elongated tank symbol used for foam or powder installations and from the multi-cylinder battery symbol used where several bottles are manifolded together.

Where this fixed fire-extinguishing bottle sign is used

Single fixed-extinguishing bottles are commonly fitted in small enclosed spaces such as paint lockers, emergency generator rooms, and equipment cabinets where a single bottle of gas provides sufficient suppression capacity without a full battery installation. This fixed fire-extinguishing bottle sign is mounted directly at the bottle or its retaining bracket, so crew and surveyors can identify the correct release point at a glance during an emergency.

Because the bottle must remain upright, securely strapped, and connected to its discharge piping at all times, its mounting position needs to stay clear of stores, tools, or other equipment placed nearby during routine work. The fixed fire-extinguishing bottle sign helps confirm the bottle has not been unstrapped, relocated, or obstructed since its last inspection, which matters in the tight compartments where these bottles are typically installed.

During weekly and monthly fire equipment inspections, crew confirm that the bottle’s pressure gauge reads within the correct operating range, that its retaining strap and discharge valve show no damage or corrosion, and that this sign remains legible at the mounting point. Any bottle found under-pressure, unsecured, or past its hydrostatic test date should be reported and corrected immediately, since a single bottle installation typically has no secondary backup for that compartment.

This sign is checked during SOLAS fire safety surveys, where the surveyor confirms that every compartment requiring fixed fire protection has an installation of the correct type and capacity, correctly signed, and within its service interval. A vessel with clearly signed single-bottle installations alongside its larger CO2 battery systems demonstrates a fire safety plan that matches equipment to the size of each protected space.

New crew are shown this sign during machinery space and auxiliary compartment inductions, since recognising a single fixed-extinguishing bottle and knowing how to trigger its manual release if the automatic system fails is a distinct skill from operating a portable extinguisher or a multi-cylinder battery room. This sign is commonly ordered alongside other fixed system signage, such as the fixed fire-extinguishing system sign used for single-tank foam and powder installations on the same vessel.

Because bottle, tank, and battery symbols all look broadly similar at a glance, ordering the correct sign for each installation matters: the round bottle symbol on this sign should only be used where a single upright bottle is actually fitted, so crew are never misdirected during a real emergency.

Keeping a record of each bottle’s weight or pressure reading alongside its hydrostatic test date lets engineers track service intervals across every fixed-extinguishing bottle on board, rather than relying on memory during a busy port call. A bottle that has lost charge between inspections is one of the more common findings raised during fire safety audits, so this fixed fire-extinguishing bottle sign is also a useful prompt to check the gauge whenever crew pass the mounting point.
