Sufficiently Invisible
A true man always picks the most life-threatening option when backed into a corner.
Jumping out the window is totally for wusses. Death by chemicals is the way to go.
If you're not familiar with the fire diamond / NFPA 704 sign, the 4/4/4 basically means that whatever inside that room can ignite and/or explode at room temperature, and even short-term exposure can cause death. The OXY sign implies that the room contains oxidizing chemicals.
