Custom Prohibition Sign

Custom Prohibition Sign | Add Your Own Text

This custom prohibition sign is a made-to-order panel supplied blank so a vessel operator can specify their own wording for a restriction that is not covered by the standard ISO 7010 catalogue. It follows the same red circle and diagonal bar format recognised throughout prohibition signage, but the message panel is left open for text such as a site-specific rule, a temporary restriction during a particular voyage, or an instruction unique to one vessel’s layout or cargo. It is typically ordered by superintendents and safety officers who have identified a hazard on board that existing stock signs do not adequately describe.

Rather than a fixed pictogram, this panel is produced with the placeholder text visible on the sample artwork, and the customer’s own wording is set in its place before printing, following the same prohibition sign layout conventions used across the rest of the range so the finished sign still looks consistent with a vessel’s other safety notices. Because no fixed catalogue message applies here, there is no IMPA or ISSA code attached to this item, and it is instead ordered by describing the exact wording, size, and mounting format required. Safety Sign Hub produces these to order for ship chandlers and marine operators who need a prohibition message the standard range does not already cover.

When A Custom Prohibition Sign Is Needed

Typical requests include restricting access to a compartment during a refit, prohibiting a particular activity in a cargo hold carrying an unusual product, or flagging a temporary hazard from ongoing maintenance that does not match any standard ISO 7010 pictogram. Some operators also use this format to phrase a rule in plain local-language wording for a trade where crew are more familiar with direct text than an unfamiliar symbol. Because the wording is entirely open, this sign is also useful for charter vessels needing a client-specific restriction for a single voyage, without committing to a permanent catalogue item.

Safety Sign Hub produces this custom prohibition sign using the same fire-retardant, UV-stable material used across the standard range, so a made-to-order panel holds up to the same weather and chemical exposure as any stocked sign despite carrying bespoke wording. Printed text is set using durable inks that resist fading from sun exposure on open decks, and a rigid panel option is available for mounting points that need a more permanent fixing than an adhesive label. Because each order is produced to the specification supplied, lead times are typically longer than for an in-stock item, so it pays to submit exact wording and sizing requirements as early as possible.

Ordering this sign involves specifying the wording to appear in the panel, the physical size needed for the intended location, and whether a self-adhesive label or rigid panel format suits the mounting surface. Providing a photo of the intended location helps confirm sizing before production begins. Vessels that need several custom messages at once, or want to compare a custom order against an existing catalogue item, can browse the broader prohibition signs range first to check whether a standard sign already covers the hazard.

Keeping A Custom Sign Consistent With The Fleet

Even though this panel carries bespoke wording, following the layout conventions of ISO 7010 prohibition graphics, detailed at iso.org, keeps a custom prohibition sign visually consistent with the rest of a vessel’s standard signage rather than looking like an improvised notice. This matters for surveyors and visiting officials who expect prohibition signage to follow a recognisable format regardless of whether the specific message is a stock item or a one-off. Fleets ordering custom signs for several vessels at once often request the same font, panel size, and border treatment across every order, so the bespoke signs read as part of the same family as the rest of the ship’s safety signage.

A custom prohibition sign is worth considering whenever a genuine hazard exists on board but no standard pictogram or worded sign in the catalogue quite matches it, rather than leaving the risk unmarked or covered only by a verbal instruction during toolbox talks. Superintendents preparing for a new trade route or an unusual cargo often identify these gaps during a pre-voyage risk assessment, allowing time to have a custom panel produced before departure. Keeping a record of any wording ordered for one vessel makes it easy to replicate the sign on a sister ship.
