2.3 Other hazards

Frostbite. Exposure of skin or eyes to compressed gases may result in freezing of the skin or eyes. This material may contain or release hydrogen sulfide. In high doses, hydrogen sulfide may produce pulmonary edema and respiratory depression or paralysis. (d) Unknown acute toxicity: None Identified. Medical conditions which are generally recognized as being aggravated by exposure: Populations with chronic respiratory, skin, or eye disease are at increased risk from exposure. Hydrocarbon exposure may sensitize the myocardium to epinephrine-induced cardiac arrhythmias (HSDB, 2014).
