Item #: XXXX
Object Class: Keter
Special Containment Procedures: SCP-XXXX and any instance of SCP-XXXX-1 is to be contained in a welded box of reinforced titanium no less than 1/2 meter deep, and a layer of tungsten at least 1/6 meter deep underneath, with no possible way to open the container. The interior of a container of SCP-XXXX-1 should be a vacuum. Containers of SCP-XXXX should be kept in its own site at Site-96 at least two miles underground, guarded at all times. Under no circumstances should any personnel attempt to let an instance of SCP-XXXX-1 free from its container without explicit permission from 4/5ths of O5 Command. Any personnel attempting to open SCP-XXXX or an instance of SCP-XXXX-1's container without permission is to have their contract terminated.
If any instance of SCP-XXXX-1 is to breach its container, Site-96 is to be evacuated immediately and permanently closed off from the outside world. All oxygen inside the facility should be immediately removed to prevent continued spread. Recontainment of SCP-XXXX-1 is impossible, it is only possible to prevent its continued spread.
It is integral that no instance of SCP-XXXX-1 ever reaches the surface.
Description: SCP-XXXX is a single lit match, discovered in Germany on April 12, 2009. In all tests of SCP-XXXX, the match has proven to be unable to be extinguished, continuing to be lit even underwater or in cold environments. SCP-XXXX's flame can easily cause fire to any surface. Anything being burned by a flame created by SCP-XXXX is permanently considered an instance of SCP-XXXX-1 and can itself create more instances of SCP-XXXX-1. It seems that nearly every solid nonmetal solid material is flammable to SCP-XXXX-1 and it is hot enough to melt nearly every metal (See Addendum XXXX-A)
As soon as an instance of SCP-XXXX-1 begins to spread, it will quickly consume the surrounding area and beyond, as long as there is oxygen in the air. If there is no oxygen, any instance of SCP-XXXX-1 continues to burn, with no possible way to put out the flame.
Different instances of SCP-XXXX-1 have varying temperatures, ranging between 2000°C and 2600°C. Temperatures above and below this have not been reported.
It is currently unknown what happens when a humanoid is turned into an instance of SCP-XXXX-1. SEE ADDENDUM SCP-XXXX-B
Addendum SCP-XXXX-A:
Test results from 6/16/2009, two months after retrieval by the Foundation.
METALS EXPERIMENT - JUNE 16, 2009
Subject: SCP-XXXX
Procedure: SCP-XXXX was placed in a vacuum 15m x 15m in size. The match was held up in the middle of the room by a robotic arm made of titanium protruding from the floor. Metals were lowered into the room via another titanium robotic arm protruding from the ceiling. A variety of common metals were tested to determine the best material to contain SCP-XXXX inside. Metals were placed 5mm above SCP-XXXX's flame and left for a maximum of 2 hours each.
Results:
Analysis: As of now, no instance of SCP-XXXX-1 has surpassed a temperature of 2600°C, however, Tungesten was chosen over Molybdenum due to the significantly higher melting point, in case an instance of SCP-XXXX has a temperature above 2600°C.
