Inert Gas Installation Sign

Inert Gas Installation Sign – FS0128

This inert gas installation sign shows the IMO fire control symbol marking equipment forming part of the vessel’s inert gas system. The “IG” symbol follows the standard IMO fire control symbol convention used on fire control plans and at the equipment itself, so it is recognisable to crew regardless of language.

Where this inert gas installation sign is used

An inert gas installation supplies low-oxygen gas to cargo tanks on tankers and other vessels, reducing the risk of explosion by keeping the atmosphere in the tank below the level needed to support combustion. This inert gas installation sign marks exactly where the generator, scrubber, deck water seal, or other key equipment of the system is located, so crew can find and check it quickly.

This sign is fixed directly at or above the inert gas equipment, typically in machinery spaces and on deck along the inert gas line, as required by the vessel’s fire control plan, so the installation’s location is always obvious at a glance. If cargo operations or an emergency call for the inert gas system to be checked or shut down, crew need to locate the correct equipment without delay.

Every part of this equipment on board should be marked the same way, so crew build a consistent expectation of what to look for regardless of which part of the vessel they are in. Equipment that blends into its surroundings or is left unmarked is far slower to find under pressure than equipment identified by this sign.

This sign is checked during SOLAS fire safety surveys, where the surveyor confirms that the inert gas installation is clearly marked, that the sign is visible and unobstructed, and that its position matches the vessel’s fire control plan. Correct labelling of the installation is a standard item reviewed during these inspections, since a missing or obscured sign can slow down verification that the system is properly accounted for.

New crew should be shown the location of the inert gas installation during safety familiarisation and fire drills, since knowing where this equipment is without hesitation can materially affect how quickly it can be checked, isolated, or restarted when needed. Clear, consistent labelling like this sign removes that hesitation.

Consistent signage also matters during a routine walk-through inspection, since an unmarked or poorly identified inert gas installation can slow down an auditor trying to confirm the vessel’s fire control plan matches what is actually fitted on board. Fitting this inert gas installation sign at the equipment keeps the fire control plan easy to verify against what is in place.

The inert gas installation should be tested regularly as part of the vessel’s routine fire safety equipment checks, since equipment that cannot be found quickly defeats the purpose of having a system ready to protect cargo tanks. Keeping this sign in good condition also makes it easier for the crew member responsible for testing to confirm the installation is accounted for, and it saves valuable time during handover briefings when a new officer needs to learn the layout of the system quickly.
