IV.   FIRE AND EXPLOSION HAZARDS DATA

Flash Point:  N/A

Explosive LimitsLower:  N/A     Upper:  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 Hazards:  When heated to decomposition, tellurium chloride may emit toxic fumes of tellurium and chlorine.

 

 

V.   HEALTH HAZARD INFORMATION

Health Hazards:

Elemental tellurium has relatively low toxicity.  It is converted in the body to dimethyl telluride which imparts a garlic-like odor to breath and sweat.  Heavy exposures may, in addition, result in headache, drowsiness, metallic taste, loss of appetite, nausea, tremors, convulsions, and respiratory arrest (Sax, Dangerous Properties of Industrial Materials, eighth edition).

Chlorides toxicity vary widely.  Sodium chloride (table salt) has very low toxicity, while carbonyl chloride (phosgene) is lethal in small doses (Sax, Dangerous Properties of Industrial Materials, eighth edition).

Acute Effects:

Inhalation:  SEVERE IRRITANT AND CORROSIVE.  Dust may cause irritation to respiratory system, dry mouth, garlic odor to breath, sweat and urine, nausea and vomiting.

Ingestion:  SEVERE IRRITANT AND CORROSIVE.  May cause dry mouth, suppression of sweat, garlic odor to breath and urine.

Skin:  SEVERE IRRITANT AND CORROSIVE.

Eye:  SEVERE IRRITANT AND CORROSIVE.

Chronic Effects:

Inhalation:  May cause anorexia, nausea, depression to the central nervous system and somnolence.

Ingestion:  May cause anorexia, nausea, depression to the central nervous system and somnolence.

Skin:  May cause dermatitis.

Eye:  No chronic health effects recorded.

Target Organs:  May affect the central nervous system, skin and eyes.

Medical Conditions Generally Aggravated by Exposure:  None Recorded

CarcinogenicityNTP?  No      IARC Monographs?  No       OSHA Regulated?  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 immediately.

INGESTION:  Give 1-2 glasses of milk or water and induce vomiting, seek medical attention immediately.  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 immediately.

EYES:  Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes.  Seek medical attention immediately.

 

 

VI.   REACTIVITY DATA

Stability:  Stable

Conditions to Avoid (Instability):  None

Incompatibility (Material to Avoid):  Water, moisture and ammonia.

Hazardous Decomposition Products:  Fumes of tellurium and chlorine.

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 Waste Disposal Regulations.

 

 

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  Wear a  NIOSH-approved dust-mist-fume cartridge respirator.

Ventilation:  Use local exhaust to maintain concentration at or below PEL, TLV.  Handle in a controlled, enclosed process.  Handle in an inert gas such as argon.  General exhaust is not recommended.

Protective Gloves:  Rubber

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 a cool, dry area in a tightly sealed container.  Wash thoroughly after handling.  Tellurium Chloride is deliquescent.  Handle and store in a controlled environment and inert gas such as argon.

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.
