Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
burns, difficulty breathing, headache, dizziness, bluish skin
color, lung damage LONG TERM EXPOSURE: tooth decay, lung damage
SKIN CONTACT: SHORT TERM EXPOSURE: irritation (possibly severe),
blisters, frostbite LONG TERM EXPOSURE: same as effects reported in
short term exposure EYE CONTACT: SHORT TERM EXPOSURE: burns,
tearing, eye damage LONG TERM EXPOSURE: same as effects reported in
short term exposure INGESTION: SHORT TERM EXPOSURE: burns, stomach
pain, irregular heartbeat 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.
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 immediate medical
attention. Thoroughly clean and dry contaminated clothing and shoes
before reuse. Destroy contaminated shoes. EYE CONTACT: Immediately
flush eyes with plenty of water for at least 15 minutes. Then get
immediate medical attention. INGESTION: Contact local poison
control center or physician immediately. Never make an unconscious
person vomit or drink fluids. Give large amounts of water or milk.
Allow vomiting to occur. When vomiting occurs, keep head lower than
hips to help prevent aspiration. If person is unconscious, turn
head to side. Get medical attention immediately. NOTE TO PHYSICIAN:
For inhalation, consider oxygen. Avoid gastric lavage or emesis.

Extinguishing Media:water Do not use dry chemicals, carbon dioxide or
halogenated extinguishing agents. Large fires: 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: If this is impossible then take the
following precautions: Keep unnecessary people away, isolate hazard
area and deny entry. Let the fire burn. For small fires, contain
and let burn. Use extinguishing agents appropriate for surrounding
fire. 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. Evacuation radius: 800 meters (1/2
mile).
Unusual Fire/Explosion Hazard:Negligible fire hazard. Oxidizer. May
ignite or explode on contact with combustible materials.

Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Protect from physical
damage. Keep separated from incompatible substances. Store outside
or in a detached building. 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. 5 ppm Any chemical
cartridge respirator with cartridge(s) providing protection against
this substance. Any supplied-air respirator. 10 ppm Any
supplied-air respirator. Any powered, air-purifying respirator with
cartridge(s) providing protection against this substance. Any
chemical cartridge respirator with a full facepiece and
cartridge(s) providing protection against this substance. Any
air-purifying respirator with a full facepiece and a canister
providing protection against this substance. Any self-contained
breathing apparatus with a full facepiece. Any supplied-air
respirator with a full facepiece. 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. 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.
