Item #: SCP-498



Object Class: Safe







Special Containment Procedures: SCP-498 is to be contained within a sound-proof bunker beneath Site ██, with a minimum of two attending Foundation Security Officers, properly equipped with noise-canceling headphones in addition to standard-issue equipment. The bunker is to be sound-proofed to noise-cancel a minimum of 95% of outgoing sound waves.

A fully automated mechanical arm is to be used to reset SCP-498.

Secondary Containment Procedure: In the event of failure, two D-Class personnel are to be locked inside with an appropriate amount of rations. They are to be informed fully of its effects and to alternate shifts sleeping and resetting SCP-498 until the failure is repaired. Security footage sans audio of the chamber is to be monitored at all times.



Following Incident I498-B, in the event of failure an on-site Foundation Security Officer is to be sent in to manually reset until such a time automated safety procedures can be reinstated.







Description: SCP-498 appears to be a Koway Brand RT-800 electronic alarm clock with yellow LED display, set to the U.S. Central Time Zone. When heard by a subject, the alarm has been seen to induce a state of increased alertness until reset. This effect prevents restful sleep in SCP-498's vicinity, although micro-naps are possible. Other than the "snooze" button and the display, none of the other functions on the device appear operational. Notably, the device continues to display time and require resetting even while not connected to a power source. Attempts to dismantle SCP-498 have not been successful in preventing it from activating, nor have they determined how it operates without an obvious power source.



Every 11 minutes, the clock's alarm goes off, gradually increasing in volume. Testing reveals that the starting alarm plays at 30 dB, increasing 4 dB every 10 seconds the snooze button is not depressed. There has been no evidence that this process will ever stop; the loudest recorded level exceeded ███ dB before reset was achieved. The sound waves produced have been seen to damage nearby structures, cause internal bleeding, and are theorized to potentially cause seismic activity.
