Section 3 - Hazards Identification



EFFECTS OF OVEREXPOSURE: NOT ESTABLISHED YET.

                  DMSO has shown very few toxic symptoms in humans. The most common are nausea, skin rashes

      General:

                           and an unusual garlic-onion-oyster smell on body and breath.

         Inhalation:       High vapor concentrations may cause headache, dizziness, and sedation.

         Eyes:             Low hazard for usual industrial/ commercial handling by trained personnel.

         Skin:             Stinging and burning of the skin as well as rashes and vesicles have been seen. A heat reaction may

                           occur if applied to wet skin. Avoid contact with DMSO solutions containing toxic material or

                           materials whose toxicological properties are not known. DMSO easily penetrates the skin and may

                           enhance the rate of skin absorption of skin-permeable substances. But because of DMSO's low

                           toxicity and its inability to carry less-permeable substances with it through the skin, it can be

                           concluded that DMSO does not pose a significant threat by skin absorption.

         Ingestion:        A low ingestion hazard.
