**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Harmful if swallowed. Causes burns.Corrosive.

Potential Health Effects
Eye:
Causes eye burns. May cause chemical conjunctivitis and corneal
damage.
Skin:
Causes skin burns. May cause cyanosis of the extremities. May cause
skin rash (in milder cases), and cold and clammy skin with cyanosis
or pale color.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May cause perforation of the digestive
tract. May be harmful if swallowed.
Inhalation:
Causes chemical burns to the respiratory tract. Inhalation may be
fatal as a result of spasm, inflammation, edema of the larynx and
bronchi, chemical pneumonitis and pulmonary edema. May cause
systemic effects. May cause burning sensation, coughing, wheezing,
laryngitis, shortness of breath, headache, nausea, and vomiting.
Inhalation at high concentrations may cause CNS depression and
asphixiation.
Chronic:
Effects may be delayed.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately. Do NOT allow victim to rub eyes or keep eyes closed.
Extensive irrigation with water is required (at least 30 minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid immediately. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do not use
mouth-to-mouth resuscitation if victim ingested or inhaled the
substance; induce artificial respiration with the aid of a pocket
mask equipped with a one-way valve or other proper respiratory
medical device.
Notes to Physician:

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool. Combustible liquid.
Vapors may be heavier than air. They can spread along the ground and
collect in low or confined areas. Containers may explode when heated.
Extinguishing Media:
In case of fire, use water, dry chemical, chemical foam, or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers. Water may be ineffective.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Remove all sources of ignition. Use
a spark-proof tool. Provide ventilation.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not get in eyes, on skin, or on clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep away from heat, sparks and flame. Do not ingest or
inhale. Use only in a chemical fume hood. Discard contaminated shoes.
Do not pressurize, cut, weld, braze, solder, drill, grind, or expose
empty containers to heat, sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Corrosives
area.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local explosion-proof ventilation to keep airborne levels to
acceptable levels.
Exposure Limits
CAS# 591-80-0:
