This is an example of an old-style fire suppression unit. It’s called a Fire Bomb, basically a large glass ball filled with carbon tetrachloride. The typical
operation is that the glass ball hangs from the ceiling, and when heat from a fire melts a weak link, the device falls and shatters and spreads the liquid carbon tetrachloride around to put the fire out.
This is an example of one
http://blog.modernmechanix.com/catapulted-bomb-puts-out-fire/ that is launched from a spring.
“Catapulted “Bomb” Puts Out Fire. A GLASS “bomb” fire extinguisher throws itself into the flames when heat melts a plug to release spring tension in the wall bracket. When catapulted,
the bursting bulb spreads an extinguishing fluid to smother flame.”

I need the collective wisdom of the group…
I’m trying to think of any chemical that is soluble in benzene and has NO significant hazardous characteristics other than toxicity (i.e.,
not flammable, corrosive, water-reactive, etc.). However, the more toxic it is, the better…
I do not want the actual chemical – just the name. I’m trying to create a hypothetical “what-if” scenario for an upcoming discussion about responding to chemical spills in a laboratory.
If you have any suggestions, please reply direct to
