Storing and handling Propane sultone
Storage conditions
PRECAUTIONS FOR "CARCINOGENS": Storage site should be as close as practical to lab in which carcinogens are to be used, so that only small quantities required for ... expt need to be carried. Carcinogens should be kept in only one section of cupboard, an explosion-proof refrigerator or freezer (depending on chemicophysical properties ...) that bears appropriate label. An inventory ... should be kept, showing quantity of carcinogen & date it was acquired ... Facilities for dispensing ... should be contiguous to storage area. /Chemical Carcinogens/

Incompatible materials
Evaporation of the residue after treatment of the thietane with hydrogen peroxide is liable to explode, and must be done in an open dish. This is probably because of formation of a 2 or 3-hydroperoxide derivative.

Reactivity
PROPANE SULTONE reacts slowly with water to give 3-hydroxopropanesulfonic acid. This reaction may be accelerated by acid. May react with strong reducing agents to give toxic and flammable hydrogen sulfide.
