Some antique safes were fitted with a binary chemical theft deterrent device as seen below.


This generally consists of 2 glass vials of one containing sodium hypochlorite and the other nitro methane.


The vials are housed in a metal casing mounted on the back or inside of the safe door in line with the combination dial.


The idea is that if a thief were to drill out the dial a mechanism would trigger another device that would break the two glass vials thus causing a reaction producing chloropicrin gas a very effective respiratory irritant. Interesting and I would imagine effective deterrent.

This obviously is not your everyday incident, but the chance exists. This is simply one of those things that you file away for possible use at a later time.

Think safety and train often... CB

Thanks for passing this on Cap!
Thanks Mike, impressive as always
I know it's not your typical call, but this was new stuff for me as well. I had no idea. I really don't think anyone really knows about this little surprise for burglars. : )
Thanks Cap., I'll pass this on to my Chief. Our area is filled with people that collect antiques.
Mike,

That's pretty wild, thanks for the 411.
Mike great information as always. I think you need a new hobby.

TCSS
No, I need to get the surgery on my shoulders so I can get out of the house... What was I thinking stepping out of my engine on a wildland fire, and there was nothing but air (and a deep trench next to the front wheel) which resulted in me falling, grabbing the handrail on the side of the engine and ripping my right rotator cuff (full thickness) and breaking off a piece of bone as I managed to stop my fall... This coming May is the surgery so maybe afterwards, I might be able to take you up on your offer to get a new hobby... What I do know is that it will not be wakeboarding, kite flying or running a rototiller: ) CB
Geez Cap, Hope they fix you up good. =) Let me know progress. Try and keep yourself from going stir crazy. LOL
Thanks for the info Capt. the more you know the better off you are. Good luck with the shoulder and stay safe.
Bloody hell mate, that was nasty! It goes to show that no matter how much experience we have, no matter how much we work for and stress firefighter safety (the first you have in spades, the second I know is a major part of your thoughts and actions), accidents can happen. Have that op and get well soon, but keep up your present hooby, it gives us all good stuff to think about!
Mike,

Good luck with the rotator cuff surgery. I've had it, and the rehab SUCKS!

Just remember the Rx I told you about to stay both pain free and awake after the surgery and especially after that oh-so-painful rehab.

Ben
