Warning & Hazard Signs Ireland
Warning safety signs — the yellow-triangle hazard signs required under ISO 7010 and the Irish Safety, Health and Welfare at Work regulations — alert workers and visitors to a present danger. Safety Sign Centre supplies the full hazard range and dispatches nationwide.

When you need a warning sign
Once a hazard has been identified in your risk assessment and cannot be eliminated, a warning sign is a required control to alert people of the residual risk.
Outdoor and roadside use
For outdoor and roadside hazards we recommend Class 2 reflective on 3 mm ACM for maximum visibility and weather resistance.
