coat the walls in 148.

Addendum 035-08: In light of the mass suicide/homicide of the members of the research team tasked with translating the passages garnered from SCP-035's containment cell, the morale damage in the area, and general loss of staff dealing with SCP-035 to either death or insanity, it has been decided to coat the inner and outer walls of its containment cell with SCP-148, which has proved well in the containment of SCP-132 (see Document 132-01), in order to hopefully block out the high levels of negativity being emitted by SCP-035.

Addendum 035-09: The use of SCP-148 has worked well, causing morale and suicide rates to return to near pre-SCP-035 rates.

However, the material appears to facilitate the negativity within the cell, causing a veritable "Greenhouse Effect" inside. Personnel inside the cell have stated that they feel a heavy sense of dread, fear, anger, and general depression, as well as hearing constant, nearly inaudible whispering upon immediate entry. A prolonged stay causes severe migraines, suicidal tendencies, heavy hemorrhaging of blood vessels around the eyes and inside the mouth and nose, general hostility to others, and for the whispering to increase to almost deafening volumes, intersected by a constant mocking laughter. Exposure of more than three (3) hours inevitably results in the subject falling into a deep psychosis, and attempting to harm either themselves or others. Most spoke in Latin or Greek, despite the fact that several did not previously know how to speak said languages beforehand.
