TYPES OF
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. Diarrhoea. Vomiting.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer immediately for medical attention.

IMPORTANT DATA
Physical State; Appearance
YELLOWISH-GREEN POWDER. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes. Reacts with acids. This produces toxic fumes of arsine gas (see ICSC 0222). 

Occupational exposure limits
TLV (as As): 0.01mg/m³ as TWA; A1 (confirmed human carcinogen); BEI issued; (ACGIH 2010).
MAK: Carcinogen category: 1; Germ cell mutagen group: 3A; (DFG 2010). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol 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, peripheral nervous system, bone marrow and liver. This may result in pigmentation disorders, hyperkeratosis, perforation of the nasal septum, neuropathy, anaemia and liver impairment. This substance is carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes
Solubility in water: none 
The substance is very toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal. 

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.
Do NOT take working clothes home.
