Releases of CERCLA hazardous substances are subject to the release reporting requirement of CERCLA section 103, codified at 40 CFR part 302, in addition to the requirements of 40 CFR part 355. Oxetane, 3,3-bis(chloromethyl)- is an extremely hazardous substance (EHS) subject to reporting requirements when stored in amounts in excess of its threshold planning quantity (TPQ) of 500 lbs.

Signs and Symptoms of Oxetane, 3,3-Bis(chloromethyl)- Exposure: Signs and symptoms of acute exposure to oxetane, 3,3-bis(chloromethyl)- may include headache, dizziness, weakness and nausea. Also, irritation of the eyes, skin, respiratory tract may be observed. Esophagus or gastrointestinal tract irritation is possible if ingested. Longer term exposure may lead to allergic hypersensitivity dermatitis or asthma with bronchospasm and wheezing.

For emergency situations, wear a positive pressure, pressure-demand, full facepiece self-contained breathing apparatus (SCBA) or pressure- demand supplied air respirator with escape SCBA and a fully-encapsulating, chemical resistant suit. (EPA, 1998)

A series of oxetanes containing iodomethyl, alkoxymethyl, and alkylaminomethyl groups were synthesized. The toxicity and broncholytic activity of these compounds were determined in mice and cats. Iodo- and alkyloxy-containing oxetanes possessed lower toxicity, and N-containing oxetanes had higher toxicity than 3,3-bis(chloromethyl)oxetane, the initial product of the synthesis. All compounds containing oxetane ring manifested a pronounced broncholytic effect. 3-(Chloromethyl)-3-(butoxymethyl)oxetane, 3,3-bis(propoxymethyl)oxetane, and 3-(chloromethyl)-3-(iodomethyl)oxetane possessed the same broncholytic effect, as that of euphyllin.
