 Item number SCP-498 Object Class Safe Special Containment Procedures SCP-498 is to be contained within a soundproof 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 soundproofed to noise-cancel a minimum of 95% of outgoing soundwaves. A fully automated mechanical arm is to be used to reset SCP-498. Secondary containment procedure. In the event of failure, two Class D 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 stands audio of the chamber as it is monitored at all times. Any incident I-498-B in the event of failure and 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 Co-Way brand RT-800 electronic alarm clock with yellow LED display set to the US 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 a device appear operational. Notably, the device continues to display time and require resetting even when not connected to a power source. Experts 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 eleven minutes the clock's alarm goes off, gradually increasing in volume. Testing reveals the starting alarm plays at thirty decibels, increasing four decibels every ten seconds the snooze button is not depressed. There have been no evidence that this process will ever stop. The loudest recorded level exceeded ██ decibels 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. Addendum 498-A, containment protocol updated. See Incident Report I-498-B. Incident Report I-498-B. Due to a malfunction in the automated mechanical arm, secondary containment procedures were activated. Two D-class personnel were utilized until a replacement arm could be manufactured and deployed. D-4112 and D-4113 were in day three of their containment procedure, and post-incident indicates severe sleep deprivation and stress due to prolonged exposure to SCP-498. The two D-class were observed conversing during this time, although lip reading proved to be ineffective in determining the nature of the conversation. At 10.4506 PM, D-4113 was observed depressing the snooze button on the device. At 10.6-39 PM, D-4112 begins to become noticeably and increasingly agitated, gesturing towards SCP-498 and D-4113. 10.5704 PM, D-4113 is seen becoming more and more aggressive. D-4112 appears to be attempting to reason with him. 10.5750 PM, D-4112 attempts to reach for the device. D-4113 pushes D-4112 away. At this time, the attending security officer knows the situation and be a closed-circuit camera. 10.5823 PM, SCP-498 has still not been reset. Attending security officers decide to intervene. 10.5845 PM, D-4112 and D-4113 are seen shouting at one another, with the latter standing over SCP-498. Security officer ██████ Wilson enters the bunker without noise-canceling headphones, a violation of containment protocol. 10.5853 PM, Officer Wilson appears to be arguing with the 2D class, presumably ordering them to reset the device. 10.5908 PM, D-4112 again attempts to reach SCP-498, at which point he is struck by D-4113 and incapacitated. 10.5912 PM, Officer Wilson draws the baton and engages D-4113. Note, D-4113 was convicted of murdering his CO and several fellow soldiers during a tour of duty in Iraq. 10.5924 PM, D-4113 wrestles the baton from Officer Wilson, subsequently subduing him. Security officer ██████ Thomas entered at this point, equipped with headphones and his sidearm. 10.5929 PM, Officer Thomas draws his sidearm and fires twice, missing both time before D-4113 closes the distance between them. A scuffle ensues. 10.5946 PM, Officer Thomas' headphones are knocked away, both personnel are exhibiting severe pain at this point, presumably due to SCP-498. Water footage vibrating due to acoustic stress. 11.002 PM, Officer Thomas manages to put distance between himself and D-4113 and fire his sidearm. D-4113 is terminated. Officer Thomas stumbles from the bunker, sealing SCP-498 and the occupants inside. Despite ruptured eardrums, he managed to activate the containment breach emergency switch before passing out. 11.0156 PM, Camera fails due to acoustic stress. 11.2558 PM, due to an unrelated simultaneous breach at site. Containment teams arrived nearly 25 minutes after the alarm was activated. Upon arriving at the scene, it was discovered that D-4112 had at some point crawled himself to SCP-498 and activated the snooze reset. He was found repeatedly depressing the button, despite suffering from burst eardrums and internal bleeding. After action report, new containment protocol initiated. Both security officers ██████ Wilson and ██████ Thomas were diagnosed with eardrum rupture, resulting in deafness. Officer Wilson treated for severe internal bleeding, both reassigned. D-4112 was treated for severe internal bleeding, commended for preventing a potentially catastrophic containment breach and successfully terminated at the end of the month.
