Industry Warning Signs

Industry Warning Signs help identify hazards in industrial workplaces where machinery, vehicles, chemicals, electrical equipment and operational risks may be present. Also known as industrial warning signs, hazard warning signs or factory warning signs, they help alert employees, contractors and visitors before they enter hazardous areas.

These signs are commonly used in factories, warehouses, manufacturing sites, engineering workshops, construction areas, logistics centres, utilities, plant rooms and processing facilities.

Typical installation locations include machinery areas, loading bays, electrical rooms, chemical stores, production lines, forklift routes, restricted zones and maintenance areas.

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