Crushing Hazard Sign

Crushing Hazard Sign – ISO 7010 Warning Symbol HS0026

This Crushing Hazard sign warns crew and contractors that converging machine parts, closing doors or moving structural elements can trap or crush a person who is caught between them. It follows the internationally recognised ISO 7010 warning pictogram format, showing a figure caught between two converging surfaces on the standard photoluminescent yellow triangle so the crushing hazard reads instantly regardless of the reader’s first language.

As SKU HS0026 in the Hazard Signs range, it is built for continuous marine exposure and suits watertight doors, hydraulic ramps, mooring winches, hatch mechanisms and any point where converging surfaces present a crushing risk.

The pictogram shows a standing figure with arrows indicating two surfaces closing in from either side, rendered in black inside the warning triangle, a graphic that communicates the trapping and crushing mechanism without needing text or a specific machine type.

Because a crushing hazard often develops from equipment that appears to be moving slowly or predictably, the sign gives an essential reminder that even a slow-closing door or ramp can trap a limb or torso before a person has time to react. The photoluminescent base keeps the crushing hazard warning visible for a period after lighting fails, which matters at watertight doors and hatch mechanisms that may operate during a power interruption.

Why Crushing Hazard Marking Matters

A crushing injury from a closing door, ramp or winch mechanism can cause severe and permanent harm, and the risk is heightened by the fact that converging machinery often moves with enough force to overcome an instinctive attempt to pull free.

Standardised crushing hazard signage keeps hands, limbs and bodies clear of the closing point during routine operation, and it supports the vessel’s safe working procedures around watertight doors, mooring equipment and hatch mechanisms. It also warns visiting contractors and new crew who may not know which doors or ramps close under power rather than manual control.

Compliance and Certification

This sign is produced to align with IMO shipboard safety signage guidance and the ISO 7010 graphical symbol set used to flag mechanical trapping hazards across the maritime industry, supporting the ISM Code’s requirement for documented control of moving machinery risks. A visible crushing hazard warning at watertight doors, ramps and winch stations is a documented control that classification surveyors and Port State Control officers look for when reviewing a vessel’s mechanical safety arrangements.

Installation Recommendations

Mount the sign directly on or beside the converging mechanism, at a height that is seen before hands or limbs are placed near the closing point, using the pre-drilled fixing holes with marine-grade fasteners for exterior doors, ramps and deck machinery exposed to weather and vibration.

The self-adhesive backing suits interior hatch surrounds and cabinet-style closing mechanisms where drilling is not practical. Check the sign during routine rounds and equipment maintenance to confirm it remains legible and correctly positioned relative to the current closing point, moving it if the mechanism itself is relocated or replaced during a refit.
