Slippery Surface Hazard Sign

Slippery Surface Hazard Sign

A slippery surface hazard sign earns its keep on exposed decks where seawater spray, rain, and routine wash-down leave standing moisture on steel plating for hours at a time. This version, HS0051, is built specifically around that wet-deck scenario: open working decks, weather decks, and pump room floors where water is a constant working condition rather than an occasional spill.

HS0051 is cross-referenced to IMPA 33.7574 and ISSA 47.575.74, distinct from the other slippery-surface pictograms in the range, and is supplied at 200x150mm. Ordering against the correct code matters here because the range includes several related hazard signs covering different wet-surface contexts, and a superintendent restocking a vessel’s warning signage needs the right one fitted at the right location rather than a generic substitute.

Fitted near deck drains, hose reel stations, and the top of external ladders, this slippery surface sign gives crew a standing reminder to slow down and use handrails whenever the deck is actively wet, which on many trades is most of the working day.

Wet-Deck Use Cases

The clearest application for HS0051 is any weather deck, bunkering station, or open working area that is routinely hosed down, subject to spray over the rail, or exposed to rain during cargo operations. Because these areas cycle between dry and wet conditions through a single watch, a fixed slippery surface sign gives a constant visual cue rather than relying on crew memory of which areas were wet an hour earlier. It is equally suited to fish processing decks and any area where routine cleaning leaves a persistent film of water or effluent on the working surface.

Marine-Grade Construction

This is a non-luminous hazard sign printed on standard fire-retardant marine-grade vinyl, chosen for its resistance to saltwater exposure, UV from direct sun on an open deck, and the abrasion that comes from foot traffic and deck gear being dragged across it. The print sits under a protective laminate so repeated wash-down does not lift or fade the graphic over the vessel’s operating life. Class C and Class D vinyl grades are both available to match your vessel’s sign specification.

Mounting and Regulatory Context

HS0051 can be supplied as a self-adhesive label for flush application to bulkheads and deckhouse walls, or as a rigid panel for mounting on rails, stanchions, or free-standing frames near the wet area itself. A well-sited slippery surface sign is a low-cost control that supports the broader housekeeping and slip-prevention duties covered by the graphical symbol conventions referenced at iso.org. It is stocked alongside related warnings in the Hazard Signs category, making it easy to complete a deck safety fit-out in a single order alongside overhead, trip, and toxic-material notices.

Keeping the correct IMPA and ISSA reference on file also means a repeat order after dry dock pulls the same wet-deck pictogram, not a stairway or galley variant intended for a different part of the vessel.

Choosing the Right Slippery Surface Sign

Because the range covers several distinct slippery-surface pictograms for different areas of a vessel, it helps to think in terms of location before placing an order: HS0051 for exposed weather decks and wash-down areas, a stairway-specific variant for internal ladderways, and an interior version for galleys and mess spaces. Ordering the wet-deck slippery surface sign against IMPA 33.7574 and ISSA 47.575.74 specifically ensures the pictogram matches the open-deck context rather than an indoor equivalent, which matters when a superintendent is checking delivered stock against a detailed fit-out drawing before a vessel goes back into service.
