4. FIRST AID MEASURES



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

breathing. 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.



INGESTION: If swallowed, drink plenty of water, do NOT induce vomiting. Get immediate medical

attention. Induce vomiting only at the instructions of a physician. Do not give anything by mouth to

unconscious or convulsive person.



ANTIDOTE: amyl nitrite, inhalation; sodium nitrite, intravenous; pyridoxine, intravenous; urea, intravenous.

5. FIRE FIGHTING MEASURES



FIRE AND EXPLOSION HAZARDS: Severe fire hazard. Severe explosion hazard. The vapor is heavier

than air. Vapors or gases may ignite at distant ignition sources and flash back. Vapor/air mixtures are

explosive. Electrostatic discharges may be generated by flow or agitation resulting in ignition or explosion.

                                                                                              Page 3 of 9



EXTINGUISHING MEDIA: alcohol resistant foam, carbon dioxide, regular dry chemical, water



Large fires: Use alcohol-resistant foam or flood with fine water spray.



FIRE FIGHTING: Move container from fire area if it can be done without risk. Dike for later disposal. Do

not scatter spilled material with high-pressure water streams. Cool containers with water spray until well

after the fire is out. Stay away from the ends of tanks. Withdraw immediately in case of rising sound from

venting safety device or any discoloration of tanks due to fire. For tank, rail car or tank truck, evacuation

radius: 800 meters (1/2 mile). Water may be ineffective.



FLASH POINT: -22 F (-30 C) (CC)

LOWER FLAMMABLE LIMIT: 1.0%

UPPER FLAMMABLE LIMIT: 50.0%

AUTOIGNITION: 194 F (90 C)

FLAMMABILITY CLASS (OSHA): IB



HAZARDOUS COMBUSTION PRODUCTS:

6. ACCIDENTAL RELEASE MEASURES



AIR RELEASE:

Reduce vapors with water spray. Stay upwind and keep out of low areas.



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.



WATER RELEASE:

Add an alkaline material (lime, crushed limestone, sodium bicarbonate, or soda ash). Absorb with activated

carbon. Collect spilled material using mechanical equipment. Subject to California Safe Drinking Water and

Toxic Enforcement Act of 1986 (Proposition 65). Keep out of water supplies and sewers.



OCCUPATIONAL RELEASE:

Avoid heat, flames, sparks and other sources of ignition. Do not touch spilled material. Stop leak if possible

without personal risk. Reduce vapors with water spray. Small spills: Absorb with sand or other non-

combustible material. Collect spilled material in appropriate container for disposal. 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



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

regulations: U.S. OSHA 29 CFR 1910.106. Protect from physical damage. Store outside or in a detached

building. Avoid contact with light. Store at room temperature. Use diking sufficient to contain total contents

plus 10%. Store under an inert atmosphere. Avoid heat, flames, sparks and other sources of ignition.

Grounding and bonding required. Keep separated from incompatible substances. 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).
