Section III.Hazards Identification
Acute Health Effects
Irritating to eyes and skin on contact. Inhalation causes irritation of the lungs and respiratory system . Inflam m ation of
the eye is characterized by redness, w atering, and itching. Skin inflam m ation is characterized by itching, scaling,
reddening, or, occasionally, blistering.
Follow safe industrial hygiene practices and always wear proper protective equipment when handling this compound.

Repeated or prolonged exposure to this compound is not known to aggravate existing medical conditions.

Section IV.First Aid Measures
Eye Contact
C heck for and rem ove any contact lenses. In case of contact, im m ediately flush eyes w ith plenty of w ater for at least 15
minutes. Get medical attention.
Skin Contact
In case of contact, im m ediately flush skin w ith plenty of w ater. Rem ove contam inated clothing and shoes. W ash
clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention.
Inhalation
If the victim is not breathing, perform m outh-to-m outh resuscitation. Loosen tight clothing such as a collar, tie, belt or
w aistband. If breathing is difficult, oxygen can be adm inistered. Seek m edical attention if respiration problem s do not
improve.
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, perform m outh-to-m outh
resuscitation. Exam ine the lips and m outh to ascertain w hether the tissues are dam aged, a possible in dication that the
toxic material was ingested; the absence of such signs, however, is not conclusive.
