HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      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! AVOID ALL CONTACT!   
Inhalation Cough. Sore throat.  Use closed system, ventilation or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin   Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Seek medical attention if you feel unwell. 
Eyes Redness. Pain.  Wear face shield or eye protection in combination with breathing protection if powder.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer for medical attention. 
Ingestion Abdominal pain. Burning sensation in the throat and chest. Vomiting. Headache. Diarrhoea. Weakness. Shock or collapse.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer immediately for medical attention.

IMPORTANT DATA
Physical State; Appearance
WHITE POWDER. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating. This produces toxic fumes of arsenic and lead. Reacts with oxidants. Reacts with strong acids. This produces toxic gas (arsine - see ICSC 0222). 

Occupational exposure limits
TLV (as Pb): 0.05mg/m³ as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 2004).
TLV (as As): 0.01mg/m³ as TWA; A1 (confirmed human carcinogen); BEI issued; (ACGIH 2004).
MAK: Carcinogen category: 1; Germ cell mutagen group: 3A; (DFG 2004). 

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
The substance is irritating to the eyes and respiratory tract. Ingestion could cause effects on the gastrointestinal tract. This may result in severe gastroenteritis, loss of fluids and electrolytes, cardiac disorders and shock. Exposure far above the OEL 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 skin, mucous membranes, bone marrow, blood, central nervous system, peripheral nervous system and liver. This may result in pigmentation disorders, perforation of the nasal septum, anaemia, nervous system impairment and liver impairment. This substance is carcinogenic to humans. Causes toxicity to human reproduction or development. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Density: 5.85 g/cm³
Solubility in water: none 
The substance is harmful to aquatic organisms. It is strongly advised not to let the chemical enter into the environment. 

NOTES
NEVER use a domestic-type vacuum cleaner to vacuum the substance, only use specialist equipment.
Depending on the degree of exposure, periodic medical examination is suggested.
