The RWP “Smart” Turnstile provides a safety checkpoint for workers upon entry into an RCA (initial entry or entry into a sub-zone). As a worker presents their dosimeter to the reader, it compares the permit that the worker has logged into against active permits for the zone that the worker is attempting to enter. The turnstile either unlocks, allowing the worker to enter with a green “go” light, or it keeps locked, blocking the worker from entering with an amber “no go” light. It features an industrial-strength PC with a 10.25 inch touch-screen monitor. The PC is used to store approved RWP’s and Tasks, as well as to access control information stored in the worker’s dosimeter.
