4. FIRST AID MEASURES
Inhalation: If inhaled, remove to fresh air. If not breathing give artificial respiration, preferabl y mouth-to-mouth.
If breathing is difficult give oxygen. Get medical attention.
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing and footwear. Wash clothing
before reuse. Get medical attention if irritation should develop.
Eye Contact: Remove contact lenses. Immediately flush with plenty of water for at least 15 minutes, holding
eyelids apart to ensure flushing of the entire surface. Washing within one minute is essential to
achieve maximum effectiveness. Seek medical at tention.
Ingestion: Not an ingestion hazard under anticipated conditions of use. For accidental ingestion if conscious,
drink one to two glasses of water (8-16 oz.). Do not induce vomiting. If vomiting should occur
spontaneously, keep the airway clear. Get medical attention. Never give anything by mouth to an
unconscious person.
Notes To Physician: Large volumes of ingested material should be removed by gastric lavage with a large bore tube,
being careful not to cause aspiration of the compound during removal of the tube.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Controls: Local exhaust ventilation as necessary to maintain exposures to within applicable
limits. Please refer to the ACGIH document, "Industrial Ventilation, A Manual of
Recommended Practices", most recent edition, for details.
Respiratory Protection: When exposures exceed the PEL or TLV, use NIOSH/MSHA approved respirator
in accordance with OSHA Respiratory Protection Requirements under 29 CFR
1910.134.
Gloves: Butyl rubber.
Skin Protection: Normal work coveralls.
Eye Protection: Chemical goggles or a face shield if splashing hazard exists.
