This is a checklist for the last person who is leaving the lab:
- Close all windows
- Turn off all the lights inside.
- Close the doors.
- Go down to the entrance door.
- Open the entrance door and press the red button on the white box above the switchboard.
- After you get out, the door will be locked (it makes a very distinctive sound).
- When outside, just close the external black door, there is no need to lock it with the padlock.
