Procedure 9011-1
A full security lockdown of the floor is to be activated. MTF Echo-12 ("Aqua Vigilance") will be tasked with recapturing SCP-9011. In the event that one or all of MTF Echo-12 are killed or otherwise put out of commission, all other access to the floor is forbidden and the floor is then considered SCP-9011’s new containment cell. Appropriate renovations are to be made, and floor plans involving SCP-9011’s new containment cell as anything else are to be edited appropriately. MTF Echo-12 is to be reconstructed with appropriately trained personnel, who are then given proper training.
In the event that this would have SCP-9011’s containment cell be the first basement floor of any site, the on-site nuclear weapons are to be detonated under the pretext of a weapons demonstration, and any organic matter found in the crater is to be classified as SCP-9011 and moved to a new site.
In the event that the on-site nuclear weapons do not clear the entirety of the site, and water or remnants of the site are still present in any quantity or usable manner, MTF Echo-13 (“Breach Clear”) are to be deployed to clear the remainder of the site.
In the event that the nuclear weapons on-site don’t activate, fail to detonate or are in some other way faulty, report directly to the highest-ranking official possible, and inform them that SCP-9011 has breached containment.
In the event that MTF Echo-13 is terminated in any way, the site location is to be attacked by artillery for the following week, at a minimum rate of one impact per ten seconds.
If there are any traces of biological matter recoverable from the site location, SCP-9011 is to be classified as “contained” and the organic matter is to be placed in the next containment area prepared.
A case of content theft: this narrative is not rightfully on Amazon; if you spot it, report the violation.
If no biological matter can be recovered from the site location, SCP-9011 is to be considered “uncontained” and significant resources are to be dedicated to finding the entity within the following decade.
If SCP-9011 cannot be found within ten years of breaching containment, all extra resources dedicated to locating it are to be recalled, and all personnel operating within one kilometer of any large body of water are to be told to “keep an eye out” and report on anything unusual that could be, in any way, linked to SCP-9011.
Under no circumstances is SCP-9011 to be considered “neutralized”, “terminated”, or “explained”.
If SCP-9011 is documented as any of these three designations and it cannot be traced to a researcher or other personnel, all personnel on all sites are to undergo an evaluation for anomalous properties, variation from human genetics, and increased desire to “flood the world”.
Should any person meet these criteria, they are to be considered SCP-9011-X and sent to explore the ocean with tracking equipment.
In the event that this procedure reveals the location of SCP-9011, 9011-X is to follow SCP-9011 as closely as possible, and attempt to lure it towards the nearest site that can contain SCP-9011’s size and weight.
CLASSIFIED, LEVEL 5 CLEARANCE REQUIRED
After SCP-9011 is successfully contained, if 9011-X’s anomalous properties, desire to “flood the world”, or genetic alterations have evolved further or gotten stronger, they are to be placed in the same containment unit as SCP-9011, and be treated as though they were the same entity as SCP-9011.
Should all attempts at reclaiming SCP-9011 fail, until further notice a GK-Dead Greenhouse end of the world scenario is to be considered in the beginning stages. The end result is expected to be a flooded earth with only waterborne life able to live.
