Metal Prohibition Sign | Electronic Restricted Zones

Unauthorised electronic signals can interfere with sensitive equipment or create hazards in high-risk environments. This prohibition sign provides a clear, immediate instruction to personnel and visitors to turn off mobile phones and radio transceivers before entering a restricted zone. It is a necessary addition to safety signs in settings such as fuel depots, specialised workshops, or medical imaging areas where signal interference is a concern.

By placing this sign at eye level on entry points, site managers reduce the risk of accidental device activation in sensitive areas. The high-contrast layout ensures the message is visible from a distance, meaning workers are alerted to the requirement before they cross the threshold. Using a durable metal substrate ensures the sign remains legible and secure even in industrial environments where plastic or adhesive options might peel or degrade over time due to heat or chemical exposure.

This specific model is manufactured from metal and measures 450x200mm. It is designed for permanent mounting in areas requiring strict electronic device restrictions. The dimensions are 450x200mm and the material is metal.
