Time: Time:

Unit 1 walks through frames. Vitalya and turnstile worker operate

and takes him to the X-ray to check
his bag. Turnstile post is unattended.
Turnstile worker substitutes Vitalya
at the frames while he inspects Unit 1.
Conclusion Conclusion
Turnstile worker has to be trained and qualified as much as Vitalya is to be able
to operate the frame. If Vitalya is at the X-ray, turnstile worker operates the frame alone.
