IV FIRE AND EXPLOSION HAZARDS DATA
Flash Point (Method used): N/A, Non Flammable Explosive Limits: LEL: N/A UEL: N/A
Extinguishing Media: USE: 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 form fire are hazardous. Isolate runoff to prevent environmental pollution.
Unusual Fire & Explosion Hazard: When heated to decomposition, copper bromide may emit toxic fumes of bromine.
V HEALTH HAZARD INFORMATION
Routes of Entry: Inhalation, skin, eyes, and ingestion.
Health Hazards Acute and Chronic:
Copper Compounds: 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).
Inhalation: Acute: SEVERE IRRITANT AND CORROSIVE. May cause a metallic taste in the mouth, congestion of the nasal mucous membranes, sneezing, coughing, difficulty breathing, irritation of the mucous membranes, depression, emaciation, altered respiratory rates, convulsions and in severe cases, psychosis and mental deterioration.
Chronic: May cause ulceration and perforation of the nasal septum and pharyngeal congestion. Chronic exposure to bromine is similar to the therapeutic ingestion of excessive bromides. Prolonged inhalation may cause pulmonary edema, bronchitis and skin eruptions.
Ingestion: Acute: SEVERE IRRITANT AND CORROSIVE. May cause abdominal pain, irritability, confusion, tremors, memory loss, slurred speech, anorexia, diarrhea 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.
Skin: Acute: SEVERE IRRITANT AND CORROSIVE. May cause irritation, skin lesions, acne-form eruptions and measle like eruptions.
Chronic: May cause dermatitis. Prolonged contact with moist skin may produce severe irritation or chemical burns.
Eye: Acute: SEVERE IRRITANT AND CORROSIVE. May cause irritation to the conjunctivitis.
Chronic: May cause permanent eye injury.
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory and gastric disorders.
Target Organs: May effect the respiratory system, lungs, skin, liver, central nervous system, and kidneys.
Carcinogenicity: NTP? No IARC Monographs? No OSHA Regulated? No
Recommended Exposure Limits: See "Section II"
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 immediately.
INGESTION: Give 2 glasses of milk or water; DO NOT induce vomiting; seek medical attention immediately.
SKIN: Remove contaminated clothing; brush material off skin; wash affected area with mild soap and water; seek medical attention immediately.
EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention immediately.
VI REACTIVITY DATA
Stability: Stable
Incompatibility (Material to Avoid): None
Conditions to Avoid-Instability: None
Hazardous Decomposition or Byproducts: Fumes of bromine

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: In accordance with Local, State and Federal Waste Disposal Regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection (specify type): NIOSH approves dust-mist-vapor cartridge respirator.
Ventilation: Local Exhaust: To maintain concentration at or below the PEL, TLV
Mechanical (General): Not recommended Special: Handle in a controlled, enclosed environment
Other: Handle in an inert gas such as argon
Protective Gloves: Rubber gloves Eye Protection: Safety Glasses
Other Protective 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.
IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storing: Keep tightly closed.
Hazard Label Information: Store in a cool dry area in a tightly sealed container, and wash thoroughly after handling.
