Core Safety Signs

Core Safety Signs cover the essential workplace signs needed to communicate hazards, instructions, restrictions and emergency information clearly. Also known as basic safety signs, workplace safety signs or essential health and safety signs, they help businesses create safer environments for employees, visitors and contractors.

Used by factories, warehouses, schools, offices, construction sites, councils and facilities managers, core safety signs support clear communication across everyday workplace activities.

Common installation locations include entrances, corridors, production areas, storage rooms, workshops, stairwells, loading bays, car parks and shared public areas.

Manufactured in the UK and available in durable materials including self-adhesive vinyl, rigid plastic and aluminium, Rainbow Safety signs are designed for reliable performance in both indoor and outdoor environments.
