Ear Protection Must Be Worn Sign

Ear Protection Must Be Worn Sign (MS0072)

Sustained exposure to high-decibel machinery noise is one of the most common and most preventable occupational hazards aboard vessels, yet it is easy to underestimate because the damage accumulates silently over repeated exposures rather than causing an obvious immediate injury. The Ear Protection Must Be Worn sign (MS0072) is a photoluminescent ISO 7010 mandatory-action marking designed to be posted at task locations and compartments where hearing protection is required. Manufactured to a maritime-grade photoluminescent specification, the sign remains clearly visible during a blackout or power failure, ensuring the instruction is never missed regardless of onboard lighting conditions.

Under SOLAS and the ISM Code, vessel operators must identify occupational noise hazards and apply consistent PPE controls at the point of risk. Posting the Ear Protection Must Be Worn sign at relevant workstations and compartments ensures crew and any visiting contractors understand the requirement immediately, supporting the vessel’s documented safety management system and helping to prevent long-term, cumulative hearing loss among the ship’s company.

Why Face Protection Matters

Noise-induced hearing loss is permanent and cannot be reversed once it occurs, which makes prevention through consistent PPE use the only effective control available to crew working around loud machinery, pumps, or compressors. Ear defenders or plugs reduce the sound pressure level reaching the inner ear to a safe threshold, but only if worn correctly and consistently every time the hazard is present. Posting the Ear Protection Must Be Worn sign at the relevant task location removes any doubt about when hearing protection is required, for both experienced crew and new personnel unfamiliar with the vessel’s noise hazards.

Compliance and Certification

This sign is produced to the ISO 7010 international graphical symbol standard, combining the recognised blue circular mandatory-action pictogram with clear supporting text so the requirement is understood by crew of any nationality. The ISM Code requires shipowners and operators to identify occupational noise hazards and implement effective controls, including PPE signage, as part of the vessel’s safety management system, while SOLAS reinforces the broader duty to keep all persons aboard informed of hazards to their health and safety. For the complete international regulatory framework, see the IMO’s SOLAS overview at imo.org. Keeping the Ear Protection Must Be Worn sign legible and current supports a positive outcome at ISM audit and flag-state inspection.

Installation Recommendations

Mount the sign at eye level near any task location or machinery item with a sustained high-noise output, such as pumps, compressors, and workshop tools. Charge the photoluminescent surface under normal lighting for the recommended period so it performs correctly if power is lost, and secure the sign with corrosion-resistant fasteners or marine-grade adhesive suited to the mounting surface. Record the sign’s position on the vessel’s safety plan so it is checked during routine safety rounds and replaced promptly if damaged or faded.
