Flash Point (Method used): N/A Autoignition Temperature: N/A
Flammable Limits: Upper: N/A Lower: N/A
Extinguishing Media: Not applicable. Use suitable extinguishing media for surrounding materials and type of fire.
Special Fire Fighting Procedures: Firefighters must wear full face, self-contained breathing apparatus with full protective clothing
to prevent contact with skin and eyes. Fumes from fire are hazardous. Isolate runoff to prevent environmental pollution.
Unusual Fire & Explosion Hazard: When heated to decomposition, copper iodide may emit toxic fumes of hydrogen iodide and
iodine compounds. Can react violently with potassium. Light sensitive.
V HEALTH HAZARD INFORMATION
Routes of Entry: Inhalation: YesSkin: Yes Ingestion: Yes
Health Hazards (Acute and Chronic):
Copper compounds: In animals, inhalation of copper dust has caused hemolysis of the red blood cells, deposition of hemo-
fuscin in the liver and pancreas, and injury to the lung cells; injection of the dust has caused cirrhosis of the liver and pancreas, and a
condition closely resembling hemochromatosis or bronzed diabetes (Sax, Dangerous Properties of Industrial Materials, eighth
edition).
Prolonged absorption of iodides may produce 鈥渋odism: which is manifested by skin rash, running nose, headache and
irritation of mucous membranes. In severe cases, the skin may show pimples, boils, redness, black and blue spots, hives and blisters.
Weakness, anemia, loss of weight and general depression may occur. Generally very soluble in water and easily absorbed into the
body (Sax, Dangerous Properties of Industrial Materials, eighth edition).
Inhalation: Acute: DANGER-POISON. May cause a metallic taste in the mouth, congestion of the nasal mucous membranes and
irritation of the mucous membranes.
Chronic: May cause ulceration and perforation of the nasal septum and pharyngeal congestion.
Ingestion: Acute: DANGER-POISON. May cause human systemic effects and acute copper toxicity.
Chronic: May cause irritation to the gastrointestinal tract and chronic copper toxicity. May cause damage to the nervous system,
kidneys and enlarge the liver. Large amounts may cause thyroid disease.
Skin: Acute: May cause irritation.
Chronic: May cause dermatitis, rashes, pimples, boils, redness, black and blue spots, hives and blisters.
Eye: Acute: May cause irritation to the conjunctiva.
Chronic: No chronic health effects recorded.
Target Organ: May affect the respiratory system skin, liver central nervous system, and kidneys.
Medical Conditions Generally Aggravated By Exposure: Pre-existing respiratory and gastric disorders.
Recommended Exposure Limits: See 鈥淪ection II鈥? LD 50/LC 50: No toxicity data recorded
Carcinogenicity: No
Signs and Symptoms of Exposure:
Inhalation: May cause a red, dry throat, metallic taste in mouth, congestion of the nasal and pharyngeal, sneezing, headache,
excitability, dizziness, difficulty breathing, burning eyes and lacrimation.
Ingestion: Human systemic effects may cause: diarrhea, evidence of thyroid hyperfunction. Large quantities may cause: abdominal
pain, nausea, vomiting and diarrhea. In severe cases, purging, excessive thirst and failure of the circulatory. Acute copper toxicity
may cause: fever, tachycardia, hypotension, hemolytic anemia with intravascular hemolysis, oliguria, uremia, coma and cardiovascu-
lar collapse. Chronic copper toxicity may cause: nausea, vomiting, epigastric pain, yellow watery diarrhea, dizziness, general debility,
jaundice, and green stools, salvia and vomitus.
Skin: May cause rashes, pimples, boils, redness, black and blue spots, hives, blisters, itching and swelling.
Eye: May cause redness, itching, burning sensation and watering.
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove victim to fresh air; keep warm and quiet; give oxygen if breathing is difficult and seek medical attention.
INGESTION: Give 1-2 glasses of mild or water and induce vomiting. Seek medical attention. Never induce vomiting or give
anything by mouth to an unconscious person.
SKIN: Remove contaminated clothing; brush material off skin; wash affected area with mild soap and water. Seek medical attention.
EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention.
VI REACTIVITY DATA

VII SPILL OR LEAK PROCEDURES
Steps to be Taken in Case Material is Released or Spilled: Wear appropriate respiratory and protective equipment specified in
Section VIII- Special Protection Information. Isolate spill area and provide ventilation. Vacuum up spill using a high efficiency
particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Take care not to raise dust.
Waste Disposal Method: Dispose of in accordance with Local, State and Federal Regulations.
Hazard Label Information: Store in cool, dry area. Store in tightly sealed container. Wash thoroughly after handling
Precautions to Be Taken in Handling and Storing: Protect from light and keep tightly closed.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): NIOSH-approved dust-mist-vapor cartridge respirator.
Ventilation: Local Exhaust: To maintain concentration at or below the PEL, TLV
Mechanical (General): Recommended
Protective Gloves: Rubber gloves Eye Protection: Safety glasses
Other Protective Clothing or Equipment: Protective gear suitable to prevent contamination
Work/Hygienic/Maintenance Practices: Implement engineering and work practice controls to reduce and maintain concentration of
exposure at low levels. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly
before eating and smoking. Do not blow dust off clothing or skin with compressed air.
