No Workwear Sign

No Workwear Sign

A no workwear sign is used to mark spaces aboard ship where site clothing, overalls or work boots must not be worn, most commonly galleys, mess rooms, crew accommodation and other clean areas where contamination from oil, grease or grime carried on workwear is a genuine hygiene or safety concern. This sign gives crew and visiting contractors a clear, immediate reminder to change or remove protective clothing before entering, rather than relying on a verbal house rule that new crew or visitors may not know.

Manufactured to ISO 7010 pictogram conventions, this no workwear sign presents a black prohibition symbol on a white background within the standard red circle and diagonal bar, so the restriction is understood instantly regardless of the reader’s first language. Stocked under IMPA code 33.8574 and ISSA code 47.585.74, this sign is a simple reorder item for ship chandlers and vessel operators fitting out galleys, mess areas and accommodation spaces during a refit or routine resupply.

Where a no workwear sign is fitted

Typical locations for a no workwear sign include galley entrances, mess room doors, laundry and accommodation passageways, and any clean area where food is prepared or crew rest, all of which benefit from keeping oil, fuel residue or general grime carried on overalls out of the space. Engine room crew, deck hands and contractors moving between working areas and living quarters are the main audience for this pictogram, since they are most likely to be wearing protective clothing that is appropriate on deck or in the engine room but not appropriate in a galley or mess room. Positioning the sign at the doorway, rather than further inside the space, gives people the chance to change or remove workwear before crossing the threshold.

Safety Sign Hub manufactures every no workwear sign in a fire-retardant, photoluminescent material, consistent with the rest of our prohibition sign range, so the sign remains legible even if lighting in a passageway or mess area is reduced. The substrate is chosen to withstand cleaning products, humidity and general galley or laundry conditions without the pictogram fading or lifting, so a sign fitted near a galley entrance continues performing after repeated wipe-downs over the life of the vessel.

Safety Sign Hub stocks this no workwear sign in standard marine signage sizes, with a self-adhesive format that suits a smooth galley or mess room door and a rigid panel option for a passageway wall that sees frequent contact and cleaning. Ordering under the IMPA and ISSA codes listed here means a ship chandler can match the exact pictogram already fitted elsewhere on board, keeping galley and accommodation signage visually consistent whenever a refit or resupply calls for replacements.

Supporting hygiene and housekeeping standards

Displaying a no workwear sign at galley, mess and accommodation entrances supports the general housekeeping and hygiene expectations reflected in vessel safety management systems and aligns with the pictogram conventions of ISO 7010. For fleet operators, ordering the same IMPA and ISSA coded sign for every vessel keeps clean-area signage consistent from ship to ship, helping crew recognise a no workwear sign immediately and adjust their clothing before entering, regardless of which vessel in the fleet they are currently serving on.

Because galleys and mess rooms are used continuously throughout a voyage, the doorway pictogram tends to see more day-to-day traffic than most other prohibition signs on board, which is why a durable, easy-to-clean surface matters as much as a clear pictogram. A sign that can be wiped down with the same products used on galley surfaces, without the print lifting or the colour dulling, stays effective for years rather than needing replacement after repeated contact with cleaning chemicals or steam. Fitting one at every relevant doorway, rather than only the main galley entrance, also covers secondary access points such as a pantry or store room where the same clothing restriction applies.

This no workwear sign marks areas such as clean rooms or galleys where standard workwear must be removed to prevent contamination hazards. Browse our full range of Prohibition Signs for more IMO-compliant maritime safety signage.
