EFFECTS OF OVEREXPOSURE
  INHALATION AND INGESTION ARE HARMFUL AND MAY BE FATAL.
  INHALATION OF VAPORS MAY CAUSE HEADACHE, NAUSEA, VOMITING, DIZZINESS,
  DROWSINESS, IRRITATION OF RESPIRATORY TRACT, AND LOSS OF CONSCIOUSNESS.
  LIQUID MAY BE IRRITATING TO SKIN AND EYES.  PROLONGED SKIN CONTACT MAY
  RESULT IN DERMATITIS.  EYE CONTACT MAY RESULT IN TEMPORARY CORNEAL DAMAGE.
  LIQUID IS READILY ABSORBED THROUGH THE SKIN.  CONTACT WITH SKIN HAS
  A DEFATTING EFFECT, CAUSING DRYING AND IRRITATION.  OVER EXPOSURE TO
  VAPORS MAY CAUSE IRRITATION OF MUCOUS MEMBRANES, DRYNESS OF MOUTH AND
  THROAT, HEADACHE, NAUSEA AND DIZZINESS.
  INGESTION MAY CAUSE NAUSEA, VOMITING, GASTROINTESTINAL IRRITATION, AND
  BURNS TO MOUTH AND THROAT.
  CHRONIC EFFECTS OF OVEREXPOSURE MAY INCLUDE KIDNEY AND/OR LIVER DAMAGE.
