Revision 0:
Special Containment Procedures: SCP-7581 although similar to SCP-066 does not need to be boxed like SCP-066 although if breached and not connected to a Host* (A.K.A | SCP-7581-2) then use of a steel box with a soundproof padded interior is required SCP-7581 is to be set in the center of its containment chamber surrounded by caution tape on the floor 6 feet in every direction and a steel box to be placed overhead and needs to be able to drop quickly. When preparing to contain SCP-7581 headphones playing music or any kind of sound very loud is recommended to keep the voices out of one’s head. Only personnel with Level 4 authorization are allowed to perform tests on SCP-7581 and only with permission from the O5 Council.
Revision 4:
Special Containment Procedures (Updated:August 12, 1997): SCP-7581 does not need any extreme containment when contained, although if breached and not attached to a Host* (A.K.A | SCP-7581-2) then use of a steel box with a soundproof and padded interior is required. The reason SCP-7581 is classified as a keter-impetus is due to it's unstability and very dangerous actions when Foundation Staff are inside of the containment chamber. SCP-7581 is known to randomly attack Foundation Staff who enter its chamber and uses the member as a host, creating a zombie-like entity. SCP-7581 is to be set in the center of its containment chamber surrounded by caution tape on the floor 6 feet in every direction, that is the maximum danger zone. A steel box 7' tall and 5' wide is to be placed overhead using an automatic pulley system for recontainment if the SCP is stationary. When preparing to contain SCP-7581 headphones playing music or any kind of aoudio very loud is recommended to keep the voices out of one’s head. SCP-7581-2 is to be killed by MTF members if uncontained or rouge, aiming for the heart is the only way to kill SCP-7582-2. Only personnel with Level 4 authorization are allowed to perform tests on SCP-7581 and only with permission from the O5 Council.
