4. FIRST AID MEASURES



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 immediate medical attention. Thoroughly clean and dry contaminated clothing and

shoes before reuse. Destroy contaminated shoes.

5. FIRE FIGHTING MEASURES



FIRE AND EXPLOSION HAZARDS: Negligible fire hazard. Containers may rupture or explode if

exposed to heat.



EXTINGUISHING MEDIA: carbon dioxide, regular dry chemical



Large fires: Use regular foam or flood with fine water spray.



FIRE FIGHTING: Do not get water inside container. Move container from fire area if it can be done

without risk. Cool containers with water spray until well after the fire is out. Stay away from the ends of

tanks. Keep unnecessary people away, isolate hazard area and deny entry.



FLASH POINT: not flammable

6. ACCIDENTAL RELEASE MEASURES



OCCUPATIONAL RELEASE:

Stop leak if possible without personal risk. Reduce vapors with water spray. Do not get water directly on

material. Do not get water inside container. Keep unnecessary people away, isolate hazard area and deny

entry. Small spills: Flood with water. Large spills: Dike for later disposal. Stay upwind and keep out of low

areas. Ventilate closed spaces before entering. Evacuation radius: 150 feet. 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).

STORAGE: Store and handle in accordance with all current regulations and standards. Notify State

Emergency Response Commission for storage or use at amounts greater than or equal to the TPQ (U.S. EPA

SARA Section 302). SARA Section 303 requires facilities storing a material with a TPQ to participate in

local emergency response planning (U.S. EPA 40 CFR 355.30). Store in a well-ventilated area. Subject to

storage regulations: U.S. OSHA 29 CFR 1910.101. Store below 52 C. Store in a cool, dry place. Keep

separated from incompatible substances.
