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.
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.

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.
