151-50-8	Potassium cyanide	>96	205-792-3

Section 3 - Hazards Identification

Appearance: white crystalline powder.
Danger! May be fatal if inhaled, absorbed through the skin or swallowed. Contact with acids liberates toxic gas. Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. Hygroscopic (absorbs moisture from the air). Corrosive to aluminum.
Target Organs: Central nervous system, lungs, eyes, thyroid, skin.


Potential Health Effects
Eye: Causes eye irritation. Causes redness and pain.
Skin: May be fatal if absorbed through the skin. Contact with skin causes irritation and possible burns, especially if the skin is wet or moist. If absorbed, causes symptoms similar to those of ingestion. Concentrated HCN vapor may also be absorbed through the skin.
Ingestion: May be fatal if swallowed. 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. May cause nausea and vomiting.
Inhalation: May be fatal if inhaled. 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). Causes respiratory tract irritation. 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 be metabolized to cyanide which in turn acts by inhibiting cytochrome oxidase impairing cellular respiration. Chronic exposure to cyanide solutions may lead to the development of a "cyanide" rash, characterized by itching, and by macular, papular, and vesicular eruptions, and may be accompanied by secondary infections. Exposure to small amounts of cyanide compounds over long periods of time is reported to cause loss of appetite, headache, weakness, nausea, dizziness, and symptoms of irritation of the upper respiratory tract and eyes.

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 imme diately.
Skin: Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion: SPEED IS ESSENTIAL. A DOCTOR MUST BE NOTIFIED AT ONCE. Call a poison control center. POISON material. If swallowed, get medical aid immediately. Only induce vomiting if directed to do so by medical personnel. Never give anything by mouth to an unconscious person.
Inhalation: SPEED IS ESSENTIAL, OBTAIN MEDICAL AID IMMEDIATELY. POISON material. If inhaled, get medical aid immediately. Remove victim to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Notes to Physician: Exposure should be treated as a cyanide poisoning.

Carcinogenicity:
CAS# 151-50-8: Not listed by ACGIH, IARC, NTP, or CA Prop 65.

Epidemiology: Increased incidence of several symptoms was seen in individuals exposed to cyanide, for approximately 7 years, compared to control subjects. The symptoms experienced, in descending order of frequency, were headache, weakness, changes in taste and smell,irritation of the throat, vomiting, and effort dyspnea. Enlargement of the thyroid was reported in 50% of the workers; it was attributed possibly to the effects of thiocyanate, the chief metabolite of cyanide.
Teratogenicity: Animal studies have only shown harmful effects in the offspring of animals exposed to doses which also produced significant maternal toxicity.
Reproductive Effects: See actual entry in RTECS for complete information.
Mutagenicity: See actual entry in RTECS for complete information.
Neurotoxicity: No information found
Other Studies:

Section 12 - Ecological Information

Ecotoxicity: Daphnia: Daphnia: 2 mg/l; 48H; EC50 No data available.
Environmental: Aquatic Fate: The alkali metal salts are very soluble in water, and as a result, they readily dissociate into their respective anions and cations upon release to water. The resulting cyanide ion may then form hydrogen cyanide or react with various metals present in natural water. If the cyanide ion is present in excess, complex metallocyanides may form; however, if metals are prevalent, simple metal cyanides may form.
Physical: Not expected to biodegrade or bioconcentrate.
Other: Insecticide - Do not empty into drains.

Section 13 - Disposal Considerations

Chemical waste generators must determine whether a discarded chemical is classified as a hazardous waste. US EPA guidelines for the classification determination are listed in 40 CFR Parts 261.3.
