------------------------------------------------------------------------Effects of Overexposure
INHALATION: Major potential route of exposure. Minimal effects have
observed at levels below 1000 ppm. Dizziness, drowsiness,
and throat irritation possible at levels above 1000 ppm.
Unconsciousness and death at levels above 10,000 ppm.
Blood pressure depression, cardiac sensitization, and
ventricular arrhythmia can result from exposure to near-
anesthetic levels.
EYES: Liquid can cause slight, temporary irritation with slight,
temporary corneal injury. Vapors can irritate eyes.
SKIN: Prolonged or repeated contact with liquid can cause freezing of
skin tissue, defatting, and dermatitis.
INGESTION: Single-dose toxicity is low to moderate. If vomiting
should occur, the liquid can be aspirated into the lungs,
which can cause chemical pneumonia and systemic effects.
Human psychotropic, gastrointestinal, and central nervous
system effects possible.
------------------------------------------------------------------------Emergency and First Aid Procedures
INHALATION: Remove to fresh air. If breathing has stopped, administer
artificial respiration. Seek medical attention.
EYES: Flush eyes for at least fifteen minutes with clear water. If
irritation persists, seek medical attention.
SKIN: Wash with soap and water. For frostbite, seek immediate medical
attention.
INGESTION: DO NOT INDUCE VOMITING! Give 2 glasses of water and
immediately seek medical attention.
NOTE: Adrenalin and similar cardiac stimulants should NOT be used to
treat effects of overexposure to this product. See section I.
None of the ingredients in this product are listed on the OSHA, IARC,
NTP list of possible carcinogenic, mutagenic, or teratogenic chemicals.
