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.



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

medical attention.



INGESTION: DO NOT induce vomiting. Never make an unconscious person vomit or drink fluids. Give

large amounts of water or milk. When vomiting occurs, keep head lower than hips to help prevent aspiration.

If person is unconscious, turn head to side. Get medical attention immediately.



NOTE TO PHYSICIAN: For inhalation, consider oxygen. For ingestion, consider esophagoscopy. Avoid

gastric lavage.





5. FIRE FIGHTING MEASURES



FIRE AND EXPLOSION HAZARDS: Negligible fire hazard. Moderate explosion 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. Stop flow of gas.



LOWER FLAMMABLE LIMIT: 15%

                                                                                                 Page 3 of 7

UPPER FLAMMABLE LIMIT: 28%

AUTOIGNITION: 1204 F (651 C)





6. ACCIDENTAL RELEASE MEASURES



AIR RELEASE:

Reduce vapors with water spray. Collect runoff for disposal as potential hazardous waste.



SOIL RELEASE:

Trap spilled material at bottom in deep water pockets, excavated holding areas or within sand bag barriers.

Dike for later disposal. Add dilute acid. Absorb with sand or other non-combustible material.



WATER RELEASE:

Collect spilled material using mechanical equipment.



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).





7. HANDLING AND STORAGE



STORAGE: Store and handle in accordance with all current regulations and standards. Subject to storage

regulations: U.S. OSHA 29 CFR 1910.111. Protect from physical damage. Store outside or in a detached

building. Inside storage: Store in a cool, dry place. Store in a well-ventilated area. Avoid heat, flames, sparks

and other sources of ignition. Keep separated from incompatible substances. Store in a cool, dry place. Store

in a well-ventilated area. 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).
