SCP 0.12 {IDEA} [Rough Ideas]

SCP 0.12 is an infinite usage bomb. it appears to be a hand made Time bomb, but it has multiple uses and never destroys during explosion. the boundaries this object can be used to is unsafe. a few major uses are as followed: Extremely toxic fumes, High radius nuclear detonations, Spontaneous combustion, etc. the usage of this devices are not time rippling, world ending, but are extremely fatal. it is easily containable, but must be under guard by very well trusted members of the site it is located. this SCP does not need any CD Testing, but when tested must be activated from a large distance away and can only be tested in areas that are not populated and are far away from civilizations.

Please tell me what you think of this idea. it sucks, but its my first idea I've pulled through with. i'm still working on most ideas, but i don't know if i will pull through with this one if the feedback is negative.
