Stable under normal temperatures and pressures.
Strong oxidizing agents.
Oxides of sulfur, thallium fumes.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Extinguishing media: For small fires, use dry chemical, carbon dioxide, water spray or regular foam.
When heated to decomposition, it emits very toxic fumes of thallium and sulfur oxide.
Fire may produce irritating, corrosive and/or toxic gases.
TLV (as Tl): ppm; 0.1 mg/m3 (as TWA) (skin) (ACGIH 1992-1993).
May cause reproductive and fetal effects.
May be fatal if swallowed. May cause liver and kidney damage. May cause alopecia (loss of hair). Large doses of thallium may produce hypotension and bradycardia.
May cause respiratory tract irritation.
May cause skin irritation.
May cause eye irritation.
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.
