Section III. Hazards Identification
Harmful if ingested or inhaled. Minimize exposure to this material. Severe overexposure can result in injury or death.
Acute Health Effects
This material produces an irritating stench. Do not inhale and always use under a fume hood. Inhalation can result in
inflammation of the respiratory system, headaches, nausea, and vomiting. Always cover all exposed skin with an
impermeable layer and use proper eye protection. A OSHA/MSHA approved dust and vapor respirator is required when
working with this material.
Follow safe industrial hygiene practices and always wear proper protective equipment when handling this compound.
Chronic Health Effects CARCINOGENIC EFFECTS : Not available.
MUTAGENIC EFFECTS : Not available.
TERATOGENIC EFFECTS : Not available.
DEVELOPMENTAL TOXICITY: Not available.
Repeated or prolonged exposure to this compound is not known to aggravate existing medical conditions.
Section IV. First Aid Measures
Eye Contact Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15
minutes. Get medical attention.
Skin Contact In case of contact, immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Wash clothing
before reuse. Thoroughly clean shoes before reuse. Get medical attention.
Inhalation If the victim is not breathing, perform mouth-to-mouth resuscitation. Loosen tight clothing such as a collar, tie, belt or
waistband. If breathing is difficult, oxygen can be administered. Seek medical attention if respiration problems do not
improve.
Ingestion INDUCE VOMITING by sticking finger in throat. Lower the head so that the vomit will not reenter the mouth and throat.
Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth
resuscitation. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible indication that the
toxic material was ingested; the absence of such signs, however, is not conclusive.
