Quarry Extreme Danger Sign

The Quarry Extreme Danger Sign provides a strong visual warning for quarry, mining and aggregate sites where multiple hazards may be present. It warns of soft edges and falling rocks while clearly stating that unauthorised access is prohibited.

Designed for placement around quarry entrances, boundaries and hazardous work areas, this sign helps communicate serious site hazards to employees, contractors, visitors and members of the public before they enter a restricted area.

Where Is This Sign Used?

The Quarry Extreme Danger Sign is suited to areas where quarry operations, unstable ground, steep edges or falling material may create significant hazards.

Common locations include:

• Quarry entrances
• Quarry boundaries and perimeter fencing
• Aggregate processing sites
• Excavation areas
• Mining operations
• Rock faces and cuttings
• Areas with soft or unstable edges
• Restricted operational zones
• Access roads and gates

Choosing the Right Sign Size

For quarry entrances, perimeter fencing and locations where vehicles approach the warning from a distance, a larger sign may provide better visibility.

Related Hazards

Helps Comply With

Clear hazard and access signage can form part of a quarry or workplace system for communicating hazards and restricting entry to operational areas.

The Quarry Extreme Danger Sign does not replace barriers, fencing, site inductions, risk assessments or other controls required for the hazards present. Appropriate controls should be determined for the specific site and work activities.
