SCP-811 should be kept in a climate-controlled, cylindrical glass enclosure, between ten (10) and twenty (20) (inclusive) metres in diameter, filled to a depth of no less than two and a half (2.5) metres on average with wetland soil and stagnant fresh water. It is to be furnished with a variety of aquatic plants from its native swamp, as the remaining vegetation there has exhibited the adaptation to regrow quickly from injuries endured during contact with SCP-811 as long as the roots are undamaged. Logs of manageable size and additional humus-rich soil may be provided for good behavior. Water depth is not to exceed half a metre (0.5) at its lowest point. Height of the enclosure must be no less than five (5) metres above the highest soil point. Temperature is to be kept at 25°C, and humidity should be kept above 70%. There is to be a decontamination airlock chamber between the door into the enclosure and the door into the rest of the facility. Air that is ventilated into the enclosure should not be recirculated back into the rest of the facility under any circumstances. The methane resulting from SCP-811's normal interaction with its environment is not anomalous and may be bottled for use as fuel. No heated elements or open flames are permitted inside the enclosure. The enclosure must be tested daily for pH and microbe levels in both the soil and water, as well as for changes in chemical composition. Enclosure should be cleaned biweekly, preferably by D-class personnel. All discarded waste should be put in quarantine for analysis before disposal by standard biohazard protocol. Subject is to be given at least five (5) kg of live food 24 hours after its completion of its previous meal. Subject is not averse to preying on humans, and it is recommended that personnel not enter the enclosure if SCP-811 has not fed in over 16 hours. No invasive medical procedure may be performed on SCP-811 outside of emergency situations in which such a procedure is required to save the subject's life. Minimally invasive procedures require review and unanimous approval by SCP-811's assigned medical team and the current project head. See Document 811-b for a list of substances that may be administered as medication to SCP-811. All requests by the subject are to be reviewed by both an overseeing animal enrichment specialist and at least one Level 3 personnel before approval, and the review should not take more than 48 hours, unless exceptional circumstances dictate otherwise. While CP-811 is not generally aggressive unless it feels hungry or threatened, all handling personnel are to be cautioned that it is still an opportunistic ambush predator, and safety precautions must still be taken to avoid possible injury or infection. All personnel entering the enclosure must wear full-body, non-organic biohazard suits and breath masks, and must be in groups of at least two. No personnel are to enter the enclosure if they have open wounds or sores anywhere on their body. Those suffering from asthma or other respiratory-affecting conditions are prohibited from entering the enclosure without a signed note from a physician with Level 4 security clearance.8964 copyright protection2008ＰＥＮＡＮＡSoGav1xaPr 維尼
