Objects to be transferred into the cleanroom must be cleaned before.
Put small objects into a precleaned plastic container for the transport.
Remove dust from the container or from the bigger object with the vacuum cleaner. This should be done directly in front of the cleanroom door.
Switch on the lights from outside and open the entrance door using the code number.
If you enter the cleanroom in the evening (5:00 pm and later), on weekends or on Fridays switch the cleanroom to operation mode (put the two switches to position 2). Afterwards when you leave switch again both to position 1.
Cleanroom log book:
Every time you enter the cleanroom area please indicate your name, date and time and your activity into the cleanroom log book which you find in the sit-over area. Make remarks about anomalies and problems.
In the sit-over area you can regulate the lights (all lights on - lights partly on - all lights off) and the air flow and switch the cleanroom from stand-by to operation mode and vice versa.
First step onto the outer adhesive mat in front of the seats, sit down and put on the booties over your shoes. Turn your legs towards the inner side and enter the dressing area. Avoid touching the outer adhesive mat with the booties and the inner adhesive mat with your shoes.
Inside the Cleanroom control center in the service area you can regulate the amount of fresh air (0 % if nobody is present, 25 % or more if people are present).
In the dressing area put on the overall and the hood.
Don't wear the overall if you just enter the service area behind the cleanroom!
Enter the cleanroom area.
Put on gloves or a face mask stored on the table inside if you work with CCDs.
After work plug out the de-ionizer and turn off the main valve of the gas supply (located on the right side of the CCD detector shelf) if used and remove plug of device.
Then go back to the dressing area, put off the cleanroom garments with exception of the booties and enter the sit-over area.
Indicate your exact working time in the cleanroom log book, as well as all problems that occurred and all observations you made during your stay in the cleanroom.
If dirt is produced use the vacuum cleaner to remove it.
In case of working with chemicals use the fume hood.
In the sit-over area put off the booties, turn around your legs towards the side where the exit is. Avoid touching the outer adhesive mat with the booties and the inner adhesive mat with your shoes.
Open the entrance door using the button signed as "Türöffner" (= door opener) and switch off the lights.
Restart after an emergency shut down:
In case of a shut down pull the red emergency knob first.
Then switch the main switch at the cleanroom control center in the service area to "off" and to "on" again until all engines restart.
