How frequently should restricted area signs be displayed along restricted area boundaries?

Restricted area signs should be displayed 100 feet apart along restricted area boundaries to ensure proper communication and visibility regarding restricted zones. This distance is designed to effectively alert personnel to the presence of a restricted area while allowing for safe and efficient movement in and around these zones. By placing the signs at this interval, it enhances the likelihood that individuals will notice and heed the warnings, thereby improving security and safety protocols.

This spacing also helps to maintain a consistent standard that can be easily recognized and followed, making it clear that the area is restricted and that unauthorized access is prohibited. It balances the need for visibility and the practical considerations of spacing throughout various types of environments.
