Slip Hazard Sign

Slip Hazard Sign

A slip hazard sign placed at the top of an internal stairway does a different job to a general wet-deck warning: it flags a location where a moment’s inattention on a change of level, combined with any moisture, oil film, or worn stair nosing, turns a routine transit into a fall. HS0050 is built around that stairway and ladderway context rather than open-deck conditions.

This slip hazard sign is cross-referenced to IMPA 33.7572 and ISSA 47.575.72 and supplied at 200x150mm, a compact size intended for fitting directly beside a stair tread, handrail post, or internal ladder access rather than across a wide deck area. Because internal stairways connect decks with different traffic patterns, lighting, and cleaning schedules, they are a recurring site for slip-and-fall incidents on working vessels, and a fixed sign at the transition point is one of the simplest controls available.

Fitting HS0050 at every internal stairway and ladder access on a vessel gives crew a consistent visual cue regardless of which deck they are moving between, which matters most during the low-light hours of a night watch.

Stairway and Ladderway Applications

The primary application for this slip hazard sign is engine room stairways, accommodation ladderways, and internal access between the main deck and machinery spaces, particularly where condensation, hydraulic oil, or tracked-in water collects on stair treads. It also suits the top and bottom of external accommodation ladders used during port calls, where wet or icy conditions combine with an unfamiliar step pattern for visiting personnel. Mounting the sign at eye level at the head of the stairs, rather than only at deck level, keeps it in a crew member’s direct line of sight before they commit to the first step.

Built for Interior and Semi-Exposed Areas

HS0050 is produced on standard fire-retardant marine-grade vinyl, suited to both fully enclosed stairwells and the semi-exposed ladderways found on weather decks. The material resists the oil, grease, and condensation typical of engine room access routes without lifting at the edges, and the printed graphic is protected against the fading that comes from long-term exposure to fluorescent lighting in enclosed spaces. Both Class C and Class D vinyl are available to match the durability class specified for your vessel.

Mounting Options and Compliance

The sign can be supplied as a self-adhesive label for direct fitting to a bulkhead or stair stringer, or as a rigid panel where a stand-off mount suits a handrail post or stanchion. Positioning a slip hazard sign at every stairway transition supports the housekeeping and fall-prevention controls described in general workplace guidance from Safe Work Australia. It is grouped with related warnings in the Hazard Signs category alongside slippery-surface and overhead-obstacle notices, so a full internal access route can be signed off in one order.

Stocked Alongside Related Deck Warnings

Because engine room and accommodation stairways typically need several signs along a single run of ladderways, HS0050 is usually ordered in small batches rather than as a single unit. Keeping the IMPA 33.7572 and ISSA 47.575.72 references on file means a repeat order for a sister vessel or a later deck extension pulls the identical slip hazard sign rather than a substitute pictogram intended for open-deck or galley conditions, which keeps signage consistent across a fleet operating to a common safety specification.
