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 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 ingestion, consider gastric lavage. Consider oxygen.



5. FIRE FIGHTING MEASURES

FIRE AND EXPLOSION HAZARDS: Severe fire hazard. Vapor/air mixtures are explosive above flash

point. The vapor is heavier than air. Vapors or gases may ignite at distant ignition sources and flash back.

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

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

FIRE FIGHTING: 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. For fires in cargo or storage area: Cool

containers with water from unmanned hose holder or monitor nozzles until well after fire is out. If this is

impossible then take the following precautions: Keep unnecessary people away, isolate hazard area and deny

entry. Let the fire burn. Withdraw immediately in case of rising sound from venting safety device or any

Page 3 of 7

discoloration of tanks due to fire. For tank, rail car or tank truck: Evacuation radius: 800 meters (1/2 mile).

Do not attempt to extinguish fire unless flow of material can be stopped first. Flood with fine water spray.

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

after the fire is out. Apply water from a protected location or from a safe distance. Avoid inhalation of

material or combustion by-products. Stay upwind and keep out of low areas. Water may be ineffective.

FLASH POINT:                                 36 F (2 C) (CC)

LOWER FLAMMABLE LIMIT:                       9.7%

UPPER FLAMMABLE LIMIT:                       12.8%

AUTOIGNITION:                                860 F (460 C)

FLAMMABILITY CLASS (OSHA): IB

6. ACCIDENTAL RELEASE MEASURES



OCCUPATIONAL RELEASE:

Avoid heat, flames, sparks and other sources of ignition. 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
