Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
irritation, nausea, headache, symptoms of drunkenness, suffocation
LONG TERM EXPOSURE: cancer SKIN CONTACT: SHORT TERM EXPOSURE:
irritation LONG TERM EXPOSURE: no information is available EYE
CONTACT: SHORT TERM EXPOSURE: irritation LONG TERM EXPOSURE: no
information is available INGESTION: SHORT TERM EXPOSURE: stomach
pain, dizziness LONG TERM EXPOSURE: no information is available
Medical Cond Aggravated by Exposure:
======================= First Aid Measures =======================
First Aid: INHALATION: If adverse effects occur, remove to
uncontaminated area. Give artificial respiration if not breathing.
If breathing is difficult, oxygen should be administered by
qualified personnel. 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 a large amount is swallowed, get medical attention. NOTE TO
PHYSICIAN: For inhalation, consider oxygen.
===================== Fire Fighting Measures =====================
Flash Point:-63 F (-53 C) (SCC)
Autoignition Temp:743 F (395 C)
Lower Limits:1.5%
Upper Limits:8.9%
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. 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. Avoiinhalation of material or combustion
by-products. Stay upwind and keep out of low areas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Vapor/air mixtures
are explosive. The vapor is heavier than air. Vapors or gases may
ignite at distant ignition sources and flash back.
================== Accidental Release Measures ==================
Neutralizing Agent:
====================== Handling and Storage ======================
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. Store in a cool, dry place. Store in a well-ventilated
area. Store outside or in a detached building. Keep separated from
incompatible substances.
Other Precautions:
============= Exposure Controls/Personal Protection =============
Respiratory Protection:Under conditions of frequent use or heavy
exposure, respiratory protection may be needed. Respiratory
protection is ranked in order from minimum to maximum. Consider
warning properties before use. Any supplied-air respirator with a
full facepiece that is operated in a pressure-demand or other
positive-pressure mode. Any self-contained breathing apparatus that
has a full facepiece and is operated in a pressure-demand or other
positive-pressure mode. 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 or process enclosure 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.
