4. FIRST AID MEASURES
Eye Exposure:
Hold eyelids open and flush with a steady, gentle stream of water for at least 15 minutes. Seek immediate medical attention, preferably with anophthalmologist. If a physician is not immediately available, eye irrigation should be continued for an additional 15 minutes.
Skin Exposure:
Immediately wipe excess material off skin with a dry cloth then wash with plenty of soap and water for at least 5 minutes. See medical
attention if irritation develops or persists. Remove contaminated clothing and shoes and clean thoroughly before re-use.
Inhalation:
Remove from immediate source of exposure, assure that victim is breathing, and supply fresh air. If not breathing, administer cardiopulmonary resuscitation (CPR). If breathing is difficult, administer oxygen if available. Seek medical treatment.
Ingestion:
Do not induce vomiting. If person is conscious, give 1-3 glasses of water to drink. To prevent aspiration of swallowed product, lay victim onside with head lower than waist. Do not leave victim unattended. Seek medical treatment.
Medical Conditions Possibly Aggravated by Exposure:
Inhalation of product may aggravate existing chromic respiratory problems such as asthma, emphysema or bronchitis. Skin contact may
aggravate existing skin disease.

301.6 C (575 F).
Foam, carbon dioxide, dry powder, water spray.
None.
Firefighters should wear NIOSH/MSHA approved positive pressure breathing apparatus with full facepiece and full chemical resistant protective clothing. Dike area to prevent runoff and contamination ofwater sources. Dispose of fire control water later.

6. ACCIDENTAL RELEASE MEASURES
Personal Protection:

Wear chemical goggles, body-covering protective clothing, chemical resistant gloves, and rubberboots. Use NIOSH approved respirator where mist occurs.
Absorb with liquid-binding material (sand, diatomite, universal binders, and sawdust). Dispose ofcontaminated material according to local, state and federal regulations. Ensure adequate ventilation.
Do not flush with water or aqueous cleansing agents.
Inform respective authorities in case product reaches water or sewage system. Do no allow to enterdrainage system, surface or ground water.

7. HANDLING AND STORAGE
Handling:
Storage:

Avoid contact with eyes, skin and clothing. Avoid breathing spray mist. Keep container closed.
Promptly clean residue from closures with dry media. Promptly clean up spills.
Store in an area that is cool, dry, well ventilated, away from combustible material, and away fromignition sources. Keep containers closed and well sealed.
