Air locks
Each staff wanting to access or leave the work area needs to pass through a personnel air lock. When leaving the air lock the person is examined for contamination in the “hot air lock”.
Inside the air lock there is a shower where the staff can clean themselves in case of contamination. Only after no contamination has been measured may the staff leave the air lock.
The cleansing water is collected and disposed of.
Also all materials taken into and out of the area need to pass through the air locks.
