Principle Routes of Exposure

Inhalation, skin contact, eye contact Inhalation This product is an asphyxiate and may exhibit anesthetic properties at very high concentrations. Initial symptoms of exposure at these concentrations are disorentation, lack of coordination, rapid respiration, headache, and nausea. Continued exposure May result in unconsciousness, coma, and possible death. Skin Contact Vapors are not irritating. Freeze burns or frostbite possible if skin is in prolonged contact with vaporizing liquid. Eye Contact Same as skin contact. Carcinogenicity
