Medical Cond Aggravated by Exposure:

First Aid

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 exposed skin with soap and water. EYE CONTACT: Flush eyes with
plenty of water. INGESTION: If a large amount is swallowed, get
medical attention. NOTE TO PHYSICIAN: For inhalation, consider
oxygen.

Fire Fighting

Autoignition Temp:581 F (305 C)
Lower Limits:2.5%
Upper Limits:100%
Extinguishing Media:carbon dioxide, regular dry chemical 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. 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: Stop leak if possible without personal risk. Let burn unless
leak can be stopped immediately. For smaller tanks or cylinders,
extinguish and isolate from other flammables. Evacuation radius:
800 meters (1/2 mile). Stop flow of gas.
Unusual Fire/Explosion Hazard:Severe explosion hazard. Vapor/air
mixtures are explosive. Electrostatic discharges may be generated
by flow or agitation resulting in ignition or explosion.

Accidental Release

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.
Neutralizing Agent:

Handling

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Subject to storage
regulations: U.S. OSHA 29 CFR 1910.102. Protect from physical
damage. Store outside or in a detached building. Keep separated
from incompatible substances. Store in a cool, dry place. Store in
a well-ventilated area. Avoid heat, flames, sparks and other
sources of ignition. Grounding and bonding required. Secure to
prevent tipping. Grounding and bonding required. Keep separated
from incompatible substances.
Other Precautions:

Exposure Controls

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 ventilation system. Ventilation
equipment should be explosion-resistant if explosive concentrations
of material are present. Ensure compliance with applicable exposure
limits.
Protective Gloves:Protective gloves are not required, but recommended.
Eye Protection:Eye protection not required, but recommended.
Other Protective Equipment:Wear appropriate chemical resistant
clothing.
