I did not find an appropriate thread for this question. I am not sure did I "lock" myself up in the centrifuge level or did I miss something.
First in the level I went to the holding pens -section and through there all the way to the pneumatic post -station (I am not sure is that correct name for the machine). I was blind and did not notice there were chemical tubes next to the machine so I did not send one to the centrifuge. I continued going forward instead and ended up back to the centrifuge room (where you drop down from the ceiling crawling space or whatever).
After that I could not get back to the pneumatic post -station, both doors near the water flow were locked. I managed to get back up to the crawling space from the centrifuge room with help from a friendly chair nearby.
Did I miss something?
