The Xenobiology Station is an attachment to the main building, though it has a saparate entrance. Albeit currently not active, there are many biohazard signs on different Federation languages, as well as Cardassian and Klingon.
On the computer display that lays to the right of the entrance door is a notice to the Engeneering crew:
ATTENTION ENGINEERING CREW
This is the site of the future Xenobiology Station. Make sure that ALL the containment fields are propperly tested and the venting system is working properly befor the station goes online. Also install the emergency transporter, as specified on Starfleet Regulation 3422-D on laboratory construction guidelines.
*Kensuke is walking around in the building, whistling an ancient japanese melody, when he reaches the Xeno Station*
Oh this is perfect-- he thinks -- great space, very appropriate location and... -- he sees the notice of the captain to the engenieers -- perfect orders! Even if this is not the captain's area, he is very aware of the measures to be taken. This will be surely a great place to work.
*Kensuke gets a good look of the station and seems very pleased*
--Now, a little personal touch... *he pulls a small piece of paper of retangular shape, with writings in ancient japanese from one of his pockets, and places it above the inner side of the station's door*
-- "Omamori". The kind of protection the manual do not cover...
