Warning - Confined Space - No Unauthorised Entry - Safety Signs by Caledonia Signs

A vital safety tool designed to alert personnel that a specific area is a confined space and restrict access to trained, authorised individuals only. Confined spaces often have limited access, poor ventilation, or hazardous atmospheres, making them extremely dangerous for untrained or unprotected personnel. The sign provides a clear visual warning to prevent accidental entry.

This sign is commonly used in industrial, manufacturing, and utility facilities, where tanks, silos, pits, sewers, or vessels are present. These spaces may contain toxic gases, low oxygen levels, or moving machinery, making unauthorised entry potentially life-threatening. By displaying this sign, organisations can significantly reduce the risk of accidents and injuries.

It is also essential in construction sites, chemical plants, and maintenance areas. Installing the sign at confined space entrances ensures that only personnel with the proper permits, training, and personal protective equipment (PPE) enter the space. This not only protects workers but also helps organisations comply with occupational safety regulations.

Additionally, the sign is durable, highly visible, and designed with bold text and contrasting colours to ensure it stands out even in busy or low-light environments. Its combination of visibility, clarity, and preventive messaging makes the “Warning – Confined Space – No Unauthorised Entry” sign an indispensable safety measure for high-risk areas.
