Laconic Containment Procedures: Do not bring the keys inside the doorway. If something bad breaches containment within SCP-004-1, bring the keys inside the doorway, close the door, and activate a nuclear weapon.

Laconic Description: SCP-004 is a large door on the side of an abandoned factory and twelve keys. Each key opens the door in question but will open to one of the twelve different realities. The keys SCP-004-7 and SCP-004-12 are the only ones that are safe. Using any others to open the door will result in instantaneous dismembrement.
