Hazards and Protection.
Storage
Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances.
Handling
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or inhale. Discard contaminated shoes.
Protection
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Respirators
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
Small spills/leaks
Vacuum or sweep up material and place into a suitable disposal container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Isolate area and deny entry. Provide ventilation.
Stability
Stable under normal temperatures and pressures.
Incompatibilities
Strong oxidizers.
Decomposition
Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, thallium fumes.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam.
Fire potential
Non-Combustible
Combustion products
Contain toxic thallium fumes.

Exposure effects
Prolonged or repeated exposure can cause psychic abnormalities such as anxiety, depression and excitability. May cause adverse nervous system effects including muscle tremors and incoordination. Prolonged or repeated exposure may cause corneal damage and the development of cataracts and glaucoma. Chronic ingestion can cause irritability, confusion, tremors, memory loss, headache, slurred speech and anorexia.
   Ingestion
May be fatal if swallowed. May cause severe digestive tract irritation with abdominal pain, nausea, vomiting and diarrhea. May cause hemorrhaging of the digestive tract. Can cause nervous system damage. May cause tremors and convulsions. May cause cardiovascular effects including low blood pressure and shock. Large doses of thallium may produce hypotension and bradycardia.
   Inhalation
May cause effects similar to those described for ingestion. Material has a low vapor pressure, so exposure to vapor is not likely. May cause kidney damage.
   Skin
May cause skin irritation. If absorbed, causes symptoms similar to those of ingestion.
   Eyes
May cause severe eye irritation. May cause blurred vision, tearing, and conjunctivitis.

First aid
 
   Ingestion
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
   Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. DO NOT use mouth-to-mouth respiration.
   Skin
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
   Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
