"In the event of a breach event by SCP-106, a human within the 10-25 years of age bracket will be prepped for recall, with the compromised containment cell being replaced and restored for use. When the cell is ready, the lure subject will be injured, preferably via the breakage of a long bone, such as the femur, or the severing of a major tendon, such as the Achilles Tendon. Lure subject will then be placed in the prepped cell, and the sound emitted by said subject will be transmitted over the site public address system."
