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: Contact local poison control center or physician immediately. Never make an unconscious
person vomit or drink fluids. 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 ingestion, consider gastric lavage and activated charcoal slurry.
5. FIRE FIGHTING MEASURES
FIRE AND EXPLOSION HAZARDS: Moderate fire hazard. Slight 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 above flash point.
EXTINGUISHING MEDIA: alcohol-resistant foam, carbon dioxide, regular dry chemical, water, alcohol-
resistant foam
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. 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
Page 3 of 8
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
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.
FLASH POINT: 111 F (44 C) (CC)
LOWER FLAMMABLE LIMIT: 1.1% @ 100 C
UPPER FLAMMABLE LIMIT: 9.4%
AUTOIGNITION: 788 F (420 C)
FLAMMABILITY CLASS (OSHA): II
6. ACCIDENTAL RELEASE MEASURES
OCCUPATIONAL RELEASE:
Avoid heat, flames, sparks and other sources of ignition. Remove 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. Keep unnecessary people away, isolate hazard area and deny entry. Stay upwind and keep out
of low areas. 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. Grounding and bonding required. Keep separated from
incompatible substances. Store in a tightly closed container. Store in a cool, dry place. Store in a well-
ventilated area.
