MUTAGENIC EFFECTS : Not available.
TERATOGENIC EFFECTS : Not available.
DEVELOPMENTAL TOXICITY : Not available.
There is no know n effect from chronic exposure to this product.Repeated or prolonged exposure to this com pound is
not known to aggravate existing medical conditions.

Section IV.First Aid Measures
Eye Contact
C heck for and rem ove any contact lenses. D O N O T use an eye ointm ent. Flush eyes w ith running w ater for a m inim um
of 15 m inutes, occasionally lifting the upper and low er eyelids. Seek m edical attention. Treat sym ptom atically and
supportively.
Skin Contact
If the chem ical gets spilled on a clothed portion of the body, rem ove the contam inated clothes as quickly as possible,
protectin g you r ow n h an ds an d body. Place th e victim u n der a delu g e sh ow er. If th e ch em ical tou ch es th e victim 's
exposed skin, such as the hands: G ently and thoroughly w ash the contam inated skin w ith running w ater and
non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin. C over the irritated skin w ith an
em ollient. Seek m edical attention. Treat sym ptom atically and supportively. W ash any contam inated clothing before
reusing.
Inhalation
If the victim is not breathing, perform artificial respiration. Loosen tight clothing such as a collar, tie, belt or w aistband.
If breathing is difficult, oxygen can be administered. Seek medical attention. Treat symptomatically and supportively.
Ingestion
IN D U C E V O M ITIN G by sticking finger in throat. Low er the head so that the vom it w ill not reenter the m outh and throat.
Loosen tight clothing such as a collar, tie, belt, or w aistband. If the victim is not breathing, adm inister artificial
respiration. Exam ine the lips and m outh to ascertain w hether the tissues are dam aged, a possible indication that the
toxic m aterial w as ingested; the absence of such signs, how ever, is not conclusive. Seek im m ediate m edical attention
and, if possible, show the chemical label. Treat symptomatically and supportively.
