Item #: SCP-5183
Object Class: Euclid
Special Containment Procedures: SCP-5183 should be contained in an airtight heat-resistant anomalous containment locker at Site-██. The locker should be kept at the temperature of the range 68–72 Fahrenheit or 20–22 Celcius. Both coolant and heating systems should be on standby at all times.
Description: SCP-5183 is approximately 1.2m or 3.9 feet long, 1.4m or 4.5 feet wide and 0.8 or 2.6 feet tall. SCP-5183 appears to be a porous blackish greyish rock, although previously determined to be composed of mainly ash. It was recently discovered on 2/12/19██ to be composed of ████████. See Addendum ████-██.
If SCP-5183 has a lower or higher temperature than usually regulated, it releases a gas composed of a material with similar properties to nicotine. This gas is now known as SCP-5183-2, and when inhaled has been found to cause damage to the lungs, lowered brain function, and oxygen deprivation. In some cases, when class D personal inhaled copious amounts of SCP-5183-2, it caused permanent damage to other organs such as the kidneys, skin, eyes and heart. See Addendum 5183-a. SCP-5183-2 doesn’t appear to affect anything non-organic. See Addendum 5183-cc. It seems to make other animals have similar effects on humans. See Addendum 5183-aa. Plants, however, (with proper light and water) seem to thrive. See Addendum 5183-b and 5183-bb.
// Order by O5-Council and Ethics Committee. Animal and Human Testing must be suspended indefinitely or until further notice //
[Addendum 5183-c: After attempting to start a fire while SCP-5183 creates SCP-5183-2 and actively fills an airtight testing room. Using standard matches, a fire was successfully created and was sustained until the test was ended. We have concluded that ██████████████ somehow holds oxygen. Dr Wilkes suggested that if we could properly filter ██████████████, we would have an infinite supply of oxygen.]
[Addendum 5183-dd: 5183-cc-ꞵ’s exterior has been constructed out of bronze and interior out of plastic for structure. Tests with 5183-cc-ꞵ have proven extremely successful, nicotine levels dropping from 73.23% to 40.89%. After this test, Dr. Wilkes asked for a departure from the SCP Foundation, and the said request has been granted. And as of 3/17/19██, Dr Wilkes has returned to normal civilian life. As such Dr. Master has taken over the project.]
[O5 Council Message: As the prospect of an infinite supply of breathable oxygen, SCP-5183’s access level has been set to Level 3.]
