CAS: 110-54-3

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, irregular heartbeat, headache, symptoms of
drunkenness, lung congestion, nerve damage, brain damage,
convulsions LONG TERM EXPOSURE: same as effects reported in short
term exposure, blurred vision, impotence, paralysis SKIN CONTACT:
SHORT TERM EXPOSURE: irritation LONG TERM EXPOSURE: blisters,
itching EYE CONTACT: SHORT TERM EXPOSURE: irritation LONG TERM
EXPOSURE: same as effects reported in short term exposure
INGESTION: SHORT TERM EXPOSURE: nausea, vomiting, headache,
symptoms of drunkenness, brain damage LONG TERM EXPOSURE: no
information on significant adverse effects
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: If person is
unconscious, turn head to side. Never make an unconscious person
vomit or drink fluids. When vomiting occurs, keep head lower than
hips to help prevent aspiration. Contact local poison control
center or physician immediately. Get medical attention. NOTE TO
PHYSICIAN: For ingestion, consider gastric lavage and activated
charcoal slurry.

Flash Point:-8 F (-22 C) (CC)
Autoignition Temp:437 F (225 C)
Lower Limits:1.1%
Upper Limits:7.5%
Extinguishing Media:regular dry chemical, carbon dioxide, water,
regular foam Large fires: Use regular 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). Water may be ineffective.
Unusual Fire/Explosion Hazard:Severe fire 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.

Spill Release Procedures: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).
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. 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
supplied-air respirator. 1100 ppm Any supplied-air respirator. Any
self-contained breathing apparatus with a full facepiece. Any
supplied-air respirator 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.
