INHALATION: If adverse effects occur, remove to uncontaminated area. Give artificial respiration if not

breathing. If breathing is difficult, oxygen should be administered by qualified personnel. Get immediate

medical attention.



SKIN CONTACT: Wash skin with soap and water for at least 15 minutes while removing contaminated

clothing and shoes. Get medical attention, if needed. Thoroughly clean and dry contaminated clothing and shoes

before reuse.



EYE CONTACT: Flush eyes with plenty of water for at least 15 minutes. Then get immediate medical

attention.

unconscious, turn head to side. Get medical attention immediately.



NOTE TO PHYSICIAN: For inhalation, consider oxygen. For ingestion, consider gastric lavage. Consider

oxygen.

6. ACCIDENTAL RELEASE MEASURES



SOIL RELEASE:

Dig holding area such as lagoon, pond or pit for containment. Dike for later disposal. Absorb with sand or other

non-combustible material.

liquid spills: Absorb with sand or other non-combustible material. Large spills: Dike for later disposal. Remove

sources of ignition. Keep unnecessary people away, isolate hazard area and deny entry. Notify Local

Emergency Planning Committee and State Emergency Response Commission for release greater than or equal

to RQ (U.S. SARA Section 304). If release occurs in the U.S. and is reportable under CERCLA Section 103,

notify the National Response Center at (800)424-8802 (USA) or (202)426-2675 (USA).





7. HANDLING AND STORAGE
