IMO A.1116(30)
Escape route signs and equipment location markings
Fire-fighting equipment signs mark the positions of extinguishers, hose cabinets, fire blankets and other equipment used in a fire response.

An extinguisher location sign shows where the appliance is kept. Additional identification can distinguish the extinguishing agent where that information is needed.
The distinction matters when different appliances are installed around a vessel. Any accompanying text must describe the actual extinguisher at that position. The sign's role is to identify the equipment clearly; operating information belongs with the relevant appliance and onboard instruction.
A hose cabinet can look like another service cupboard when viewed along a deck passage. Identification on or beside it makes its purpose visible before the door is opened.
The same applies to fire blanket containers in galleys and lockers containing fire-fighting equipment. Each marker should name what is available at that location.
Equipment behind a doorway or around a corridor turn may need both directional marking and identification at the final position. These signs answer different questions: where to go, and what is there.
Fire-fighting equipment signs also sit alongside shipboard fire control marking. The former identifies appliances and equipment locations; the latter identifies pumps, system controls and remote operating points. Clear names connect both with the vessel's fire arrangements.
Standards
IMO Resolution A.1116(30) sets out escape route signs and equipment location markings. It applies to ships built from 1 January 2019, and to ships under repair, alteration or outfitting from that date, under SOLAS chapters II-2 and III. ISO 24409-1 covers how shipboard signs are designed; ISO 24409-3 covers where they belong and how they are used together.

Code of practice: where signs belong on board and how they are used together
Signs that identify fire-fighting appliances and their locations: extinguisher signs, including versions naming the extinguishing agent, hose cabinets, fire blankets and equipment lockers, together with the directional marking that leads to them.
This range identifies appliances and equipment locations. Shipboard fire control identifies pumps, system controls and remote operating points — the installed fire protection arrangement rather than the portable equipment. Both sit alongside each other on board and should use consistent names.
ISO 24409-1 covers how the sign is designed and ISO 24409-3 covers where it belongs. IMO Res. A.1116(30) covers escape route signs and equipment location markings, which includes marking the location of fire-fighting equipment.
Not always, but it matters where different appliances are installed around a vessel. Where the sign carries text, that text has to describe the extinguisher actually at that position. Operating information belongs with the appliance and the onboard instruction, not on the location sign.
