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!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Abdominal pain. Confusion. Diarrhoea. Dizziness. Drowsiness. Headache. Vomiting. Incoordination. Paralysis. Symptoms may be delayed. See Notes.  Use closed system or ventilation.  Fresh air, rest. Refer for medical attention. 
Skin Further see Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 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. Confusion. Diarrhoea. Dizziness. Dullness. Headache. Vomiting. Incoordination. Muscle paralysis. Further see Inhalation.  Do not eat, drink, or smoke during work.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS SOLID IN VARIOUS FORMS. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic fumes including arsenic (see ICSC 0013). 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation 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
See Notes. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at at 160°C°C
Relative density (water = 1): 1.76
Solubility in water: poor 
 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of systemic arsenic poisoning do not become manifest until hours after the exposure.
Card has been partly updated in October 2005.
See sections EU classification, Emergency Response.
