4. FIRST AID MEASURES
INHALATION:
Remove from exposure immediately. Use a bag valve mask or similar device to perform artificial
respiration (rescue breathing) if needed. Get medical attention.

SKIN CONTACT:
Remove contaminated clothing, jewelry, and shoes immediately. Wash with soap or mild
detergent and large amounts of water until no evidence of chemical remains (at least 15-20
minutes). Get medical attention, if needed.

EYE CONTACT:
Wash eyes immediately with large amounts of water or normal saline, occasionally lifting upper
and lower lids, until no evidence of chemical remains. Get medical attention immediately.

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
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. Reportable Quantity (RQ): 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
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.
