Item #: SCP-4472
Object class: Euclid Keter
Special Containment Procedures: SCP-4472 must be kept in a room without air conditioning or ventilation for safety procedures. It must be in a special cage with light. When there will be blackout event, then Personnel must call Engineering and Technical department staff to turn on Emergency Generator (When generator will not work then [Mobile Task Force Beta-7] must turn on Lockdown procedure and get all SCP-4472 substances to the cage). Personnel will have to go through two airlocks that will be locked one after the other to avoid violation. In case SCP get through both locks and reaches the foundation corridors. The facility will be quarantined and no one or anything will be able to enter or leave it, as it will end with termination. Only Mobile Task Force Beta-7 will be able to re-contain this, by using ███████ weapon.
When light is off and the generator is not working. Then [Mobile Task Force Beta-7] must get to the room with a cage at a special suit with lamps or flashlights. The unit must be armed with primary Beta-7 weapons and ███████ weapon.
Description: SCP-4472 is a smog. When lights are on, then Personnel can see this is black. But when generators are broken, then it's white. Dr. [███████] thinks that is because this SCP has the energy to make photons that can be seen for the eye. Mass is not counted but is probably 4 kg/m3 (8,81849049 lb). When human will get so close to it without hazmat suit, it will infect personnel. Human on the first day will not feel anything. But later infected personnel will be hard breathing. If personnel will not get to Dr. [███████] then there will be no chance to survive. SCP will suffocate personnel and after 1 week it will get to the blood and kill personnel. Personnel can get too SCP-500 and get it on the first day to kill SCP-4472 substances at the human body. But side effects will be not good. Personnel can't sleep but if it will happen.. Then personnel will have nightmares with it.
SCP-4472 is not like light. Personnel can't test do cross-test with SCP-4472 because it will get breached. It can't out from the cage (Exception is testing with Scientific with Level-4+ clearance.
