We used to run a load test on a piece of POTS gear that would blow a reasonably large cap. (Timing in the firmware was applying voltage to something that shouldn't have had a voltage... and the circuit didn't have good enough protection.) A (very) little bit of flame and lots of smoke. Great way to get the attention of every hw/fw eng in the building... "FIRE IN THE LAB!" thankfully it was never enough to set off the smoke detectors. We also used to have (small) gear out in the cubicles. Every once in a while I'd get a whiff of "that smell" and would take a walk around cube-ville trying to figure out whose box was overheating. Good times...
