nausea, vomiting, stomach pain, chest pain, difficulty breathing,
headache, symptoms of drunkenness, hyperactivity or drowsiness,
tingling sensation, visual disturbances, bluish skin color,
paralysis, convulsions, coma LONG TERM EXPOSURE: fainting, blurred
vision, nerve damage, brain damage SKIN CONTACT: SHORT TERM

damage LONG TERM EXPOSURE: same as effects reported in short term
exposure INGESTION: SHORT TERM EXPOSURE: same as effects reported
in short term inhalation 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 swallowed,
drink plenty of water, do NOT induce vomiting. Get immediate
medical attention. Induce vomiting only at the instructions of a
physician. Do not give anything by mouth to unconscious or
convulsive person. NOTE TO PHYSICIAN: For ingestion, consider
gastric lavage.

Autoignition Temp:999 F (537 C)
Lower Limits:10%
Upper Limits:16%
Extinguishing Media:regular dry chemical, regular foam, water 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. Fight large fires from a protected location or
safe distance. Stay away from the ends of tanks. Dike for later
disposal. Do not scatter spilled material with high-pressure water
streams. Do not attempt to extinguish fire unless flow of material
can be stopped first. Use extinguishing agents appropriate for
surrounding fire. Flood with fine water spray. Cool containers with
water spray until well after the fire is out. 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. Consider downwind evacuation if material is leaking.
Unusual Fire/Explosion Hazard:Slight fire hazard. Containers may
rupture or explode if exposed to heat.

Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. 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). Protect
from physical damage. Store in a cool, dry place. Store outside or
in a detached building. Store in a well-ventilated area. Keep in
the dark. Avoid exposure to low temperatures or freezing. Keep
separated from incompatible substances.
Other Precautions:

Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. At any detectable
concentration - Any self-contained breathing apparatus that has a
full facepiece and is operated in a pressure-demand or other
positive-pressure mode. 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. 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 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:Protective clothing is not required.
