Scp 4120 A

Item #: SCP 4120-A

Object Class: Keter

Description: SCP 4120-A is a gas that SCP 4120 will release when SCP 4120 is left open for more than 3 minutes. SCP 4120-A is highly flammable, and Dr. █████ has called SCP 4120-A "greyonyx gas" (grey on icks). Not much is known about the effects of greyonyx gas, but personnel who have been exposed to SCP 4120-A reported having a pain similar to having their head inside of a vise that is slowly being closed within 24 hours of exposure which is why SCP 4120-A is nicknamed: "████████". Researchers unfortunately have difficulties testing SCP 4120-A due to it being invisible, odorless, and dissipitating rapidly, making research very difficult.
