No Exit Signs

No Exit Signs are prohibition and wayfinding signs used to clearly identify doors, corridors or routes that must not be used as an exit. They help prevent confusion during normal building use and reduce the risk of people attempting to leave through unsafe, restricted or non-exit routes.

Commonly referred to as Not An Exit Signs, No Exit Door Signs or Do Not Use As Exit Signs, they are used in workplaces, schools, hospitals, warehouses, factories, offices, public buildings and commercial premises.

Manufactured in the UK, Rainbow Safety's no exit signs are available in durable materials including self-adhesive vinyl, rigid plastic, aluminium and glow in the dark options. Suitable for indoor and outdoor use, these signs help improve navigation, safety and access control across busy premises.

No Exit Signs Guide

No Exit Signs are used to clearly indicate that a door, corridor, passageway or route does not provide a safe or permitted exit. They help prevent people from entering dead ends, restricted areas, service routes or doors that could lead to unsafe locations.

These signs are particularly useful in buildings with complex layouts, multiple doors or restricted access areas where visitors, staff or contractors may otherwise mistake a route for an exit.
