Caution Plant Room/Door Kept Locked Multi-Message Signs | Access Awareness Signs

Product Summary

Ensure safety, security, and compliance across your site with our high-visibility Caution Plant Room/Door Kept Locked Multi-Message Signs. Designed specifically for construction sites, plant facilities, and industrial environments, these access awareness signs deliver multiple critical safety warnings in one durable display.

Each sign clearly communicates that access to plant rooms is restricted to authorized personnel only and that doors must remain locked at all times. Bold text and universally recognized safety icons enhance visibility and comprehension, making these signs essential for preventing unauthorized entry, minimizing electrical hazard risks, and ensuring workplace compliance with health and safety regulations.

These multi-message signs support broader site safety efforts, complementing other essential signage such as keep clear signs, emergency access route signs, and do not block access signs. They're ideal for positioning at doorways, corridors, and entry points where restricted access and hazard awareness must be made clear.

Material & Print Options

Our Caution Plant Room/Door Kept Locked Multi-Message Signs are manufactured using durable, professional-grade materials to withstand the demands of busy construction and industrial environments.

Adhesive Vinyl: A flexible, self-adhesive option ideal for smooth surfaces such as doors, walls, and glass panels. Easy to apply and resistant to weather, water, and general wear.
3mm Rigid PVC: A strong, lightweight plastic board that offers excellent durability for both indoor and outdoor use. Suitable for mounting on walls, fences, gates, or access doors.

All signs are printed using UV-resistant inks for long-lasting visibility and colourfastness in varying environmental conditions.

Installation Info

These signs are delivered without fixings to give you flexibility in choosing the most appropriate installation method for your site. Depending on the surface and location, you may choose to:

Apply adhesive vinyl directly to clean, smooth surfaces
Use screws, cable ties, or adhesive pads to mount PVC signs (fixings not included)

Position signs at eye level and in high-traffic areas—such as plant room doors, entryways, and corridors—to maximize visibility and effectiveness.
