<p>Dear Savitha,</p>
<p><br>
</p>
<p>During covid we restricted the number of people working in the cleanroom simultaneously by implementing a booking calendar (in form of a doodle poll or something similar) along with the calendars for the equipment. As a user, you had to book a cleanroom
slot first, then the required equipment. If you include a buffer of 10%, it can work efficiently.</p>
<p><br>
</p>
<p>Hope it helps...</p>

We are experiencing a high number of people in our cleanroom, with 50-70 users at a time against a maximum capacity of 50. I would appreciate it if you could share strategies used in your facilities to reduce the number of people in the cleanroom. Do you have
any restrictions on students during the day or any incentives for working after office hours, for both startups and industry?</div>
