Medical Cond Aggravated by Exposure:

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.

Flash Point:-130 F (-90 C) (CC)
Autoignition Temp:100-126 F (38-52 C)
Lower Limits:0.8%
Upper Limits:88%
Extinguishing Media:Let burn unless leak can be stopped immediately.
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). Stop flow of gas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Gas/air mixtures are
explosive.

Spill Release Procedures:Avoid heat, flames, sparks and other sources
of ignition. Stop leak if possible without personal risk. Reduce
vapors with water spray. Keep unnecessary people away, isolate
hazard area and deny entry. Remove sources of ignition. Ventilate
closed spaces before entering. 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. Protect from physical
damage. Store and handle in a detached building. Refrigerate. Store
in a well-ventilated area. Avoid contact with air. Keep separated
from incompatible substances. Store under an inert atmosphere. Keep
separated from incompatible substances. Notify State Emergency
Response Commission for storage or use at amounts greater than or
equal to the TPQ (U.S. EPA SARA Section 302). SARA Section 303
requires facilities storing a material with a TPQ to participate in
local emergency response planning (U.S. EPA 40 CFR 355.30).
Other Precautions:

Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. 1 ppm Any
supplied-air respirator. 2.5 ppm Any supplied-air respirator. 5 ppm
Any supplied-air respirator with a full facepiece. Any
self-contained breathing apparatus with a full facepiece. Any
supplied-air respirator with a full facepiece. 15 ppm Any
supplied-air respirator operated in a pressure-demand or other
positive-pressure mode. Escape - Any air-purifying respirator with
a full facepiece and a canister providing protection against this
substance. 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 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.
