IV. FIRE AND EXPLOSION HAZARDS DATA

Flash Point: N/A

Flammability: Not flammable

Explosive Limits: Upper: N/A     Lower: N/A

Extinguishing Media: Use suitable extinguishing media for surrounding material 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: When heated to decomposition, cadmium selenide may emit toxic fumes of cadmium, selenium and oxides of cadmium and selenium.

V. HEALTH HAZARD INFORMATION

Effects of Exposure:

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

Cadmium compounds are confirmed carcinogens producing lung tumors. Poison by ingestion. Inhalation of fumes or dusts affects the respiratory tract and the kidneys. Brief exposure to high concentrations may result in pulmonary edema and death. Fatal concentrations may be breathed without sufficient discomfort to warn a worker to leave the exposure. Cadmium oxide fumes can cause metal fume fever.

Selenium compounds may cause amyotrophic lateral sclerosis, bronchial irritation, gastrointestinal distress, nasopharyngeal irritation, garlic odor on breath and sweat, metallic taste, pallor, irritability, excessive fatigue, loss of fingernails and hair, pulmonary edema, anemia and weight loss.

Acute Effects:

Inhalation: May cause irritation of the upper respiratory system, vertigo, constriction of the throat, metallic taste in the mouth and cough, garlic odor to breath, nervousness, depression, dyspnea, cyanosis, chest pain, flu-like symptoms, pulmonary edema and acute selenosis. More severe exposure may cause pulmonary fibrosis/hypertrophy of bronchial vessels and renal necrosis and/or liver damage.

Ingestion: May cause irritation of mouth, throat and digestive system, increased salivation, burning sensation and cramps in stomach, nausea, headache, vomiting, weakness, dizziness, diarrhea, shock, convulsions, coma and death.

Skin: May cause local irritation and possible burns.

Eye: May cause irritation, redness and pain.

Chronic Effects:

Inhalation: May cause irreversible lung injury, pulmonary fibrosis, damage to the olfactory nerve and chronic selenosis. All routes of entry may cause kidney damage, osteomalacia, osteoporosis, spontaneous fractures, hemolytic and iron-deficiency anemia, weight loss, irritability, renal tubular necrosis, cardiovascular effects, liver damage and prostatic and respiratory cancers.

Ingestion: May cause irreversible renal tubular dysfunction, functional changes in the liver, pancreas and adrenal glands.

Skin: May cause dermatitis.

Eye: May cause conjunctivitis and blurred vision.

Routes of Entry: Inhalation, ingestion.

Target Organs: May affect the respiratory system, liver, kidneys, prostate, blood, skin and eyes.

Medical Conditions Generally Aggravated by Exposure: Kidney, liver or respiratory dysfunction, skin, blood or bone disorders.

Carcinogenicity: NTP: Yes          IARC: Yes         OSHA: Yes

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION: Remove victim to fresh air, keep warm and quiet, give oxygen if breathing is difficult and seek immediate medical attention.

INGESTION: Give 1-2 glasses of milk or water and induce vomiting, seek immediate 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 immediate 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: Water/moisture

Incompatibility (Material to Avoid): Oxidizing agents and acids.

Hazardous Decomposition Products: Cadmium/cadmium oxide fumes, selenium/selenium oxide fumes.

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.  For spills of solid pieces: scoop or pick up mechanically.  For powder spills: Isolate spill area, provide ventilation and extinguish sources of ignition.  Scoop up or vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal.  Use care to avoid generating dust.

Waste Disposal Method: Dispose of in accordance with all Federal, State, and Local regulations.

VIII. SPECIAL PROTECTION INFORMATION

Respiratory Protection: NIOSH approved respirator.

Ventilation: Local exhaust ventilation should be utilized to keep dust levels below recommended exposure limit. General exhaust is not recommended. Use enclosed process if possible.

Protective Gloves: Rubber, butyl, PVC

Eye Protection: Vented goggles and/or face shield

Other Protective Clothing: Protective gear suitable to prevent contamination.

IX. SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage: Store in tightly sealed container in a cool, dry area. Wash thoroughly after handling.  Avoid formation of dust.  Do not breath or ingest dust.

Hazard Label Information:  Danger. Contains cadmium. Cancer hazard. Avoid creating dust. Can cause lung and kidney disease.

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 or 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.
