Why this sign: This sign should be placed at or approaching any location where the ground level drops abruptly without a protective barrier, such as an unguarded platform edge, retaining wall, or excavation perimeter. It addresses the risk of accidental falls from height caused by an unexpected change in elevation that may not be immediately visible to approaching pedestrians.

Compliance note: In Ireland, employers must provide appropriate safety signage where hazards cannot be avoided or adequately reduced by other measures, based on the workplace risk assessment, under the Safety, Health and Welfare at Work (General Application) Regulations 2007. This sign is suitable for use as part of a workplace safety-signage system where identified by that risk assessment.
