CAS: 108-10-1

Fraction By Weight: 100.0%

Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
irritation, nausea, vomiting, diarrhea, headache, symptoms of
drunkenness, coma LONG TERM EXPOSURE: drowsiness, liver enlargement
SKIN CONTACT: SHORT TERM EXPOSURE: irritation LONG TERM EXPOSURE:
same as effects reported in short term exposure EYE CONTACT: SHORT
TERM EXPOSURE: irritation, tearing LONG TERM EXPOSURE: same as
effects reported in short term exposure INGESTION: SHORT TERM
EXPOSURE: vomiting, digestive disorders, headache, symptoms of
drunkenness LONG TERM EXPOSURE: no information is available
Medical Cond Aggravated by Exposure:

First Aid: 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. Give large amounts of
water or activated charcoal slurry. When vomiting occurs, keep head
lower than hips to help prevent aspiration. If person is
unconscious, turn head to side. Get medical attention. NOTE TO
PHYSICIAN: For ingestion, consider gastric lavage. Consider oxygen.

Flash Point:64 F (18 C) (CC)
Autoignition Temp:838 F (448 C)
Lower Limits:1.2%
Upper Limits:8.0%
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 Procedures: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 ocombustion by-products. Stay upwind and
keep out of low areas. Water may be ineffective.
Unusual Fire/Explosion Hazard: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.

Spill Release Procedures: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).
Neutralizing Agent:

Handling and Storage Precautions: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. Protect from physical damage. Store outside or in a
detached building. Store with flammable liquids. Keep separated
from incompatible substances.
Other Precautions:

Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. 500 ppm Any
chemical cartridge respirator with organic vapor cartridge(s). Any
air-purifying respirator with a full facepiece and an organic vapor
canister. Any powered, air-purifying respirator with organic vapor
cartridge(s). Any supplied-air respirator. Any self-contained
breathing apparatus with a full facepiece. Escape - Any
air-purifying respirator with a full facepiece and an organic vapor
canister. Any appropriate escape-type, self-contained breathing
apparatus. For Unknown Concentrations or Immediately Dangerous to
Life or Health - Any supplied-air respirator with full facepiece
and operated in a pressure-demand or other positive-pressure mode
in combination with a separate escape supply. Any self-contained
breathing apparatus with a full facepiece.
Ventilation:Provide local exhaust ventilation system. Ventilation
equipment should be explosion-resistant if explosive concentrations
of material are present. Ensure compliance with applicable exposure
limits.
Protective Gloves:Wear appropriate chemical resistant gloves.
Eye Protection:Wear splash resistant safety goggles. Provide an
emergency eye wash fountain and quick drench shower in the
immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
clothing.
