Can't argue with you about the hazards, I'm quite aware of that.
However, Exothermic (by definition) is a process in which heat is given
off to the surroundings. Exo- is out side, -thermic is heat. An
irreversible crimp sleeve in no way qualifies as Exothermic, though
soldering could certainly qualify to the broad definition since heat is
given off to the surrounding during the process.
