medical equipment

started getting a little bit of the stuff the end of last year (here and there) and just got in a bunch .. Have to many of these things now and can't help but notice the warning that says something about explosions so figured I'd ask around see if anyone else has taken these apart before.. EKG machines, I figured it was a spark hazard but want to make sure there isn't going to be any explosions if I open one up...
cant resell any of this junk so please don't tell me to list it on eBay lol...

kind of sorted through all of the medical equipment and taken it all apart except for the ones with the explosion warnings on them!



any advice would be great..
