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. ANTIDOTE:
amyl nitrite, inhalation; sodium nitrite, intravenous; sodium
thiosulfate, infusion; oxygen.

Flash Point:flammable
Lower Limits:6.6%
Upper Limits:32%
Extinguishing Media:Let burn unless leak can be stopped immediately.
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). Do not attempt to extinguish fire unless flow of
material can be stopped first. Flood with fine water spray. Cool
containers with water. Apply water from a protected location or
from a safe distance. Avoid inhalation of material or combustion
by-products. Stay upwind and keep out of low areas. Stop flow of
gas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Gas/air mixtures are
explosive. The gas is heavier than air. Vapors or gases may ignite
at distant ignition sources and flash back.

Spill Release Procedures:Do not touch spilled material. 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.
Small dry spills: Move containers away from spill to a safe area.
Large spills: Dike for later disposal. Keep unnecessary people
away, isolate hazard area and deny entry. 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. Avoid shock or friction. Avoid heat, flames, sparks and
other sources of ignition. Keep separated from incompatible
substances. 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:

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. Ensure compliance with applicable exposure limits.
Protective Gloves:Wear appropriate chemical resistant gloves.
Eye Protection:Wear splash resistant safety goggles with a faceshield.
Provide an emergency eye wash fountain and quick drench shower in
the immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
clothing.
