It would be fair to assume it might be a lachrymator, due to its similarity to chloroacetones, I once vented a mix of hot acetone, in various stages of chlorination, over my garage, atempting to synthesise monochloroacetone, it overheated and flash boiled, vaporising quite a bit of it, I think I broke my record for shortest time to find and put on my gas mask that day
Iodoacetone will probably be a lot less volatile, due to higher atomic weight of iodine over Cl2, but still, count on having a full-face mask ready if you intend on working with it.
