Flash Point:  N/A

Autoignition Temperature:  N/A

Flammable LimitsUpper:  N/A       Lower:  N/A

Extinguishing Media:  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

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of copper iodide have not been thoroughly investigated and recorded.

In animals, inhalation of copper dust has caused hemolysis of the red blood cells, deposition of hemofuscin 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 "iodism:  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).

Acute Effects:

Inhalation:  DANGER-POISON.  May cause a metallic taste in the mouth, congestion of the nasal mucous membranes and irritation of the mucous membranes.

Ingestion:  DANGER-POISON.  May cause human systemic effects and acute copper toxicity.

Skin:  May cause irritation.

Eye:  May cause irritation to the conjunctiva.

Chronic Effects:

Inhalation:  May cause ulceration and perforation of the nasal septum and pharyngeal congestion.

Ingestion:  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:  May cause dermatitis, rashes, pimples, boils, redness, black and blue spots, hives and blisters.

Eye:  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.

CarcinogenicityNTP:  No       IARC:  No     OSHA:  No

 

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

Stability:  Stable

Conditions to Avoid:  Light

Incompatibility (Material to Avoid):  Active metals and potassium, oxidizing agents

Hazardous Decomposition Products:  Hydrogen iodide and iodine compounds

Hazardous Polymerization:  Will not occur.

 

 

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.

 

 

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  NIOSH-approved respirator.

Ventilation:  Use local exhaust to maintain concentration at or below the PEL, TLV.  General exhaust is recommended.

Protective Gloves:  Rubber gloves

Eye Protection:  Safety glasses

Other Protective Clothing or Equipment:  Protective gear suitable to prevent contamination

 

 

IX.   ADDITIONAL COMMENTS

Precautions to Be Taken in Handling and Storing:  Store in cool, dry area.  Store in tightly sealed container.  Wash thoroughly after handling.  Protect from light and keep tightly closed.

Work 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.  Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
