What happens when these 3 chemicals are mixed in air?

  1. Pentanone/Di-isopropyl Ketone (2,4-Dimethyl-3-Pentanone)
  2. Iodine, reagent grade
  3. Sodium Iodide, reagent grade.

The 3 parts make up a liquid in a tilt switch. The tilt switch can leak giving off a very unpleasant smell. Also corrosion can occur on the part. What is the smell? How dangerous is the smell? Using a fume cupboard etc, what exactly are we emitting into the atmosphere?
