Special containment procedures: Item SCP-086 is stored in a heavily soundproofed room, isolated from the rest of the facility by an airlock.
As there is some leakage from SCP-086, the surrounding area is also cordoned off. Object is currently safe, provided no unprotected personnel enter the containment zone, so handling instructions are only provided for the possibility of a security breach, or if needing to move SCP-086.
Unprotected personnel who enter the containment zone should be removed from the area as soon as possible. If they return, or show signs of being compromised by SCP-086, they must be terminated; warnings of these consequences must be displayed prominently around the containment zone.
Description: SCP-086 appears to be a regular tetrahedron approximately 25cm on each side. It constantly emits sounds
described as whispering by survivors of its effects, though in no known language.
These sounds are capable of a wide range of effects on humans, including the creation of psychosis or a mindlessly obedient state. Experiments to replicate its abilities by matching the generated frequencies, however, have failed.
All personnel who work with SCP-086 should, manpower permitting, be completely deaf. They are also required to equip provided ear defenders and an antisound generator. Before entering SCP-086's chamber, a supervisor should check that all agents are unable to hear sounds at approximately 140dB. The recommended method is to fire a blank behind them, and to watch for signs of surprise.
Agents entering the chamber should work in a group of five or more, and rehearse their actions in a separate, dummy chamber. Any deviation from this trial run in the real chamber is to be treated as a sign of falling under SCP-086's control, and if they do not heed signals to exit immediately, the agent should be terminated.
Those with level 2 security clearance or above should also see document #86-1.
