TYPES OF
HAZARD /
EXPOSURE 		ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! STRICT HYGIENE!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation See Ingestion.  Use local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin MAY BE ABSORBED! See Ingestion.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes   Wear safety goggles or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Nausea. Vomiting. Headache. Weakness. Muscle pain. Blurred vision. Restlessness. Convulsions. Increased heart rate. See Notes.  Do not eat, drink, or smoke during work. Wash hands before eating.  Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give a slurry of activated charcoal in water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
 		PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into sealable containers. Carefully collect remainder. Then store and dispose of according to local regulations.  Do not transport with food and feedstuffs.

Transport Emergency Card: TEC (R)-61GT5-I.  Separated from strong acids, fluorine, other halogens and food and feedstuffs. 

IMPORTANT DATA
Physical State; Appearance
BLUISH-WHITE VERY SOFT METAL. TURNS GREY ON EXPOSURE TO AIR. 

Physical dangers
 

Chemical dangers
Reacts with strong acids. Reacts with fluorine and other halogens at room temperature. 

Occupational exposure limits
TLV: 0.1mg/m³ as TWA; (skin); (ACGIH 2001).
MAK (2b (not established but data is available)): (DFG 2005). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
The substance may cause effects on the gastrointestinal tract, nervous system, kidneys and cardiovascular system. Exposure could cause hair loss and atrophy of nails. Ingestion could cause death. The effects may be delayed. Medical observation is indicated. 

Effects of long-term or repeated exposure
The substance may have effects on the cardiovascular system and nervous system, and may cause hair loss. Animal tests show that this substance possibly causes toxicity to human reproduction or development. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 1457°C
Melting point: 304°C
Relative density (water = 1): 11.9
Solubility in water: none  		The substance is toxic to aquatic organisms. Bioaccumulation of this chemical may occur along the food chain, for example in freshwater organisms. This substance may be hazardous to the environment. Special attention should be given to birds and mammals. It is strongly advised not to let the chemical enter into the environment. The substance may cause long-term effects in the aquatic environment. 

NOTES
Symptoms of acute thallium intoxication usually develop slowly; gastrointestinal symptoms (nausea, vomiting, abdominal pain) appear usually within few hours after exposure but neurological disorders and other symptoms may show after 2-5 days.
Depending on the degree of exposure, periodic medical examination is indicated.
Do NOT take working clothes home.
See ICSC 0336 (Thallium sulfate), 1221 (Thallium carbonate).
