 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 sound waves. A fully automated mechanical arm is to be used to reset SCP-498. Following incident I-498B, 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 CoA 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 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. Within three-eleven minutes, the clock's alarm goes off, gradually increasing in volume. Testing reveals that the starting alarm plays at thirty decibels, increasing four decibels every ten seconds the snooze button is not depressed. There has been no evidence that this process will ever stop. The loudest recorded level exceeded eight 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 498A, containment protocol updated. See incident report I-498B. Incident report I-498B. Date expunged. Site-bun-bun-bun-bun-bun. 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-4-1-1-2 and D-4-1-1-3 were in day three of their containment procedure, and post-incident psychoanalysis indicate 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 10.45.06 pm, D-4-1-1-3 was observed depressing the snooze button on the device. 10.56.39 pm, D-4-1-1-2 begins to become noticeably and increasingly agitated, gesturing toward SCP-498 in D-4-1-1-3. 10.57.04 pm, D-4-1-1-3 is seen becoming more and more aggressive. D-4-1-1-2 appears to be attempting to reason with him. 10.57.50 pm, D-4-1-1-2 attempts to reach for the device. D-4-1-1-3 pushes D-4-1-1-2 away. At this time, the attending security officers noticed the situation via closed circuit camera. 10.58.23 pm, SCP-498 has still not been reset. Attending security officers decide to intervene. 10.58.45 pm, D-4-1-1-2 and D-4-1-1-3 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. 10.58.53 pm, Officer Wilson appears to be arguing with the 2D class, presumably ordering them to reset the device. 10.59.08 pm, D-4-1-1-2 again attempts to reach SCP-498, at which point he is struck by D-4-1-1-3 and incapacitated. 10.59.12 pm, Officer Wilson draws his baton and engages D-4-1-1-3. Note, D-4-1-1-3 was convicted of murdering his CO and several fellow soldiers during a tour of duty in Iraq. 10.59.24 pm, D-4-1-1-3 wrestles the baton from Officer Wilson, subsequently subduing him. Second security officer Thomas enters at this point, equipped with headphones and his sidearm. 10.59.29 pm, Officer Thomas draws his sidearm and fires twice, missing both times, before D-4-1-1-3 closes the distance between them. A scuffle ensues. 10.59.46 pm, Officer Thomas' headphones are knocked away. Both personnel are exhibiting severe pain at this point, presumably due to SCP-498. Camera footage vibrating due to acoustic stress. 11.0002 pm, Officer Thomas manages to put distance between himself and D-4-1-1-3 and fire his sidearm. D-4-1-1-3 is terminated. Officer Thomas stumbles from the bunker, sealing SCP-498 in the occupants inside. Despite ruptured eardrums, he managed to activate the containment breach emergency switch before passing out. 11.01.56 pm, Camera fails due to acoustic stress. 11.25.58 pm, due to an unrelated simultaneous breach of sight, containment teams arrived nearly 25 minutes after the alarm was activated. Upon arriving at the scene, it was discovered that D-4-1-1-2 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-4-1-1-2 was treated for severe internal bleeding, commended for preventing a potentially catastrophic containment breach and successfully terminated at the end of the month. Lesson complete.
