**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Very toxic by inhalation, in contact with skin and if swallowed.
Contact with acids liberates very toxic gas. Very toxic to aquatic
organisms, may cause long-term adverse effects in the aquatic
environment.Corrosive.Hygroscopic (absorbs moisture from the air).
Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns. Contact may cause irritation, tearing, and burning pain. May
cause chemical conjunctivitis and corneal damage.
Skin:
May be fatal if absorbed through the skin. If absorbed, causes
symptoms similar to those of ingestion. Causes severe skin irritation
and possible burns. Substance is readily absorbed through the skin.
Ingestion:
May be fatal if swallowed. May cause severe gastrointestinal tract
irritation with nausea, vomiting and possible burns. May cause tissue
anoxia, characterized by weakness, headache, dizziness, confusion,
cyanosis (bluish skin due to deficient oxygenation of the blood),
weak and irregular heart beat, collapse, unconsciousness,
convulsions, coma and death. Human fatalities have been reported
from acute poisoning. May cause central nervous system damage and
death can be rapid.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. Causes cyanosis (bluish discoloration of skin due to
deficient oxygenation of the blood). May cause severe irritation of
the respiratory tract with sore throat, coughing, shortness of
breath and delayed lung edema. May cause effects similar to those
described for ingestion.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Prolonged
or repeated contact may cause skin necrosis and/or ulceration of the
skin. May cause reproductive and fetal effects. Chronic exposure can
affect thyroid function.
**** 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.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Discard contaminated clothing in a manner which limits
further exposure.
Ingestion:
Call a poison control center. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Get medical aid.
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:
Persons with kidney disease, chronic respiratory disease, liver
disease, or skin disease may be at increased risk from exposure to
this substance. Exposure should be treated as a cyanide poisoning.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
Wear appropriate protective clothing to prevent contact with skin
and eyes. Wear a self-contained breathing apparatus (SCBA) to
prevent contact with thermal decomposition products.
Non-combustible, substance itself does not burn but may decompose
upon heating to produce irritating, corrosive and/or toxic fumes.
Runoff from fire control or dilution water may cause pollution.
Extinguishing Media:
Do NOT use carbon dioxide. Do NOT get water inside containers. For
large fires, use water spray, fog or alcohol-resistant foam. Do NOT
use straight streams of water. Most foams will react with the
material and release corrosive/toxic gases. For small fires, use dry
chemical, dry sand, alcohol-resistant foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Do not flush into a sewer. Clean up spills immediately,
observing precautions in the Protective Equipment section. Avoid
generating dusty conditions. Provide ventilation. Evacuate
unnecessary personnel.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Wash hands before eating. Minimize
dust generation and accumulation. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Do not ingest or inhale. Do
not allow contact with water. Use only in a chemical fume hood.
Discard contaminated shoes. Keep from contact with moist air and
steam. Acids should not be used around sodium cyanide or potassium
cyanide unless absolutely necessary and then only after careful
planning. Hydrogen cyanide (HCN) formation is the greatest potential
hazard in using sodium cyanide or potassium cyanide solutions
because some HCN gas will be released.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Keep away from strong acids. Poison room locked. Keep
containers tightly closed. Store protected from moisture.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower.
