**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if swallowed. Causes
burns. May cause sensitization by skin contact. May cause cancer.
Very toxic to aquatic organisms, may cause long-term adverse effects
in the aquatic environment.Corrosive.Air sensitive.Cancer suspect
agent.
Potential Health Effects
Eye:
Causes eye burns. Effects may be delayed. May cause temporary
blindness. May cause visual impairment.
Skin:
Causes skin burns. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Toxic in contact with skin. Substance is readily absorbed through
the skin.
Ingestion:
Poison by ingestion. May cause liver and kidney damage. Causes
digestive tract burns with immediate pain, swelling of the throat,
convulsions, and possible coma. Exposure may cause anemia and other
blood abnormalities.
Inhalation:
Effects may be delayed. May cause cyanosis (bluish discoloration of
skin due to deficient oxygenation of the blood). May cause liver and
kidney damage. Causes chemical burns to the respiratory tract. May
cause lung damage. Inhalation may be fatal as a result of spasm,
inflammation, edema of the larynx and bronchi, chemical pneumonitis
and pulmonary edema. Toxic if inhaled. Inhalation may produce burning
sensation, coughing, wheezing, laryngitis, shortness of breath,
headache, nausea, and vomiting. May cause respiratory sensitization.
Chronic:
Possible cancer hazard based on tests with laboratory animals.
Prolonged or repeated exposure may cause adverse reproductive
effects. Repeated inhalation may cause chronic bronchitis. May cause
fetal effects. Repeated exposure may cause sensitization dermatitis.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
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. Discard contaminated clothing
in a manner which limits further exposure.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing
is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth
resuscitation. If breathing has ceased apply artificial respiration
using oxygen and a suitable mechanical device such as a bag and a
mask.
Notes to Physician:
Antidote:
None reported.
**** 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. Use water spray to keep fire-exposed containers
cool. Combustible liquid. Containers may explode when heated.
Powerful reducing agent.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. For large fires, use water spray, fog, or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Remove all sources of ignition. Absorb spill using
an absorbent, non-combustible material such as earth, sand, or
vermiculite. Do not use combustible materials such as sawdust. Use a
spark-proof tool. Provide ventilation. Place under an inert
atmosphere.
**** 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 container tightly closed. Keep away from heat,
sparks and flame. Do not ingest or inhale. Handle under an inert
atmosphere. Do not pressurize, cut, weld, braze, solder, drill,
grind, or expose empty containers to heat, sparks or open flames.
Use only with adequate ventilation.
Storage:
Keep away from sources of ignition. Do not store in direct sunlight.
Keep refrigerated. (Store below 4C/39F.) Store in a tightly closed
container. Corrosives area. Do not expose to air. Store under an
inert atmosphere.
**** 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
ventilation to keep airborne concentrations low. Use only under a
chemical fume hood.
