Researching room in zone 3. Size of a basic office, would have file canbinets, shelves and some tables. On the tables there would be a computer and a monitor. On the shelves there would be documents, batteries and maybe eyedrops. Also on one of the tables would be a security tape and 2 or 3 level keycard. would often spawn from a vent near one corner of the room.

I think I should be the security room as it mencina a display room where guards and scientists Avars. Is generated and supplants the flashing by a power outage.
PS: in the introduction, when you leave the room containment of SCP-173 the guard says "back there to look at SCP-173"

Creo que deberia estar la habitacion de seguridad como se lo mencina, una habitacion donde se muestre avarios guardias y cientificos. Se genera y se suplanta el parpadeo por un corte de luz.
PD: en la introduccion, cuando se sale de la habitacion de contencion de SCP-173 el guardia diga "vuelve ahi a mirar a SCP-173"

How about adding the gym room, auditorium room and housing area for scientists.As both first mentioned room (gym and auditorium) are heard randomly by the PA system and could be added to avoid mtf or 173 in the Entrance zone.
