WARNING!
COMBUSTIBLE LIQUID AND VAPOR
PHYSICAL APPEARANCE: Clear liquid
ODOR: Essentially odorless
EFFECTS
OF OVEREXPOSURE:
General:
DMSO
has shown very few toxic symptoms in humans. The most common
are nausea, skin rashes 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.
HMIS AND NFPA HAZARD RATINGS: Health - 1, Flammability - 1, Chemical
Reactivity - 0
Note:
HMIS and NFPA ratings involve data and interpretations that may vary from
company to company. In both cases the
lower the number, the less the hazard. They are intended only for rapid, general
identification of the magnitude of the
specific hazard. To deal adequately with the safe handling of this material,
all the information contained in this MSDS
must be considered.
