Hazard Warning Signs

Hazard Warning Signs alert employees, visitors and contractors to potential dangers that may cause injury, illness or property damage. Recognisable by their yellow triangular design, these signs help identify workplace hazards before people enter an area or begin a task.

Also known as warning signs, danger warning signs or hazard alert signs, they are widely used in factories, warehouses, workshops, construction sites, schools, healthcare facilities and public buildings.

Common installation locations include machinery areas, electrical rooms, chemical storage facilities, loading bays, restricted access areas, plant rooms and workplace entrances where hazards need to be clearly communicated.

Available in self-adhesive vinyl, rigid plastic, aluminium and photoluminescent materials, many of our hazard warning signs are manufactured in the UK for excellent visibility, durability and long-lasting performance.
