FIRST AID/
FIRE FIGHTING

FIRE Not combustible. 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).
Closed system and ventilation.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
•SKIN MAY BE ABSORBED! Redness. (See Ingestion.)
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES Redness. Pain.
Safety goggles , face shield or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION Abdominal pain. Convulsions. Diarrhoea. Headache. Nausea. Vomiting. Weakness. Delirium. Irregular heart beat. Coma (see Notes).
Do not eat, drink, or smoke during work. Wash hands before eating.

PHYSICAL STATE; APPEARANCE:
ODOURLESS WHITE OR COLOURLESS CRYSTALS.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing highly toxic fumes including thallium and sulfur oxides .

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 mg/m3 as TWA; (skin); (ACGIH 2004).
MAK: IIb (not established but data is available) (DFG 2004).


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.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes and the skin. The substance may cause effects on the nervous system , cardiovascular system and gastrointestinal tract . Exposure may result in hair loss. The effects may be delayed (see Notes). Medical observation is indicated. Exposure may result in death.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL

Solubility in water, g/100 ml at 20°C: 4.87

ENVIRONMENTAL
DATA

The substance is harmful to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.

N O T E S

Depending on the degree of exposure, periodic medical examination is suggested. The symptoms of acute intoxication do not become manifest until up to several days have passed. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Do NOT take working clothes home. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response.
