Custom Supplementary Sign – FS0033

Custom Supplementary Sign – FS0033

This IMO-style supplementary sign is a blank text plate template, supplied with your own custom wording printed in place of a standard pre-set label, for situations where a vessel’s fire safety or fire control equipment needs to be identified with text that falls outside the standard IMO supplementary sign range. The custom supplementary sign keeps the same construction, size, and photoluminescent performance as the standard CO2, foam, halon, powder, and water supplementary signs, so it sits alongside them as a matching, consistent part of a vessel’s fire safety signage set.

Where this custom supplementary sign is used

This sign is ordered whenever a fixed fire-extinguishing installation, release station, or piece of fire-fighting equipment needs a label that the standard supplementary sign range does not cover, such as a less common extinguishing agent, a compartment-specific instruction, or wording required by a flag state, class society, or ship operator that goes beyond the pictogram-based system. Rather than leaving such equipment unlabelled or using a mismatched sign, a custom supplementary sign lets the exact required wording be produced to the same standard as the rest of the vessel’s fixed fire-extinguishing installation sign family.

Because ships often carry equipment fitted after original construction, or systems specified by a particular owner or yard, the standard IMO supplementary sign set does not always anticipate every labelling need that arises over a vessel’s working life. This custom supplementary sign gives crew and safety officers a straightforward way to close that gap without resorting to handwritten or improvised labels that fade, peel, or fail to meet photoluminescent visibility requirements.

To order this sign, simply provide the exact wording required, and it will be produced on the same fire-retardant, photoluminescent material used across the standard supplementary sign range, ensuring it performs identically in low-light and blackout conditions. Reviewing proof text before production helps avoid errors, since correcting a fitted sign after installation is more disruptive than confirming the wording in advance.

During weekly and monthly fire equipment inspections, crew confirm that this custom supplementary sign remains legible and correctly paired with its associated pictogram or installation, in the same way as any standard supplementary sign. A sign found missing or illegible should be reordered and replaced promptly, since a custom label often marks equipment or wording that has no standard fallback sign to substitute in the meantime.

This sign is checked during SOLAS fire safety surveys alongside the vessel’s other fire control signage, where the surveyor confirms that all fixed fire-extinguishing installations are clearly and consistently labelled, including any non-standard wording specified by the operator. A vessel that uses properly produced custom supplementary signs, rather than improvised labels, demonstrates the same standard of documentation and signage discipline expected across its standard equipment.

New crew are shown any custom supplementary signs fitted aboard during safety inductions, since non-standard wording may not be immediately familiar from training on other vessels. This sign is commonly ordered alongside the fixed fire-extinguishing bottle sign when a vessel’s fixed extinguishing arrangement includes equipment or agents not covered by the standard supplementary sign range.

Because this sign is produced to order, lead times can differ slightly from stocked standard signs, so it is worth ordering custom supplementary signs as soon as a labelling gap is identified rather than waiting until the next scheduled port call or survey. Keeping a record of the exact wording used also makes reordering identical replacement signs straightforward in future.
