TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE     In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Sore throat. Cough. Headache. Nausea. Vomiting. Laboured breathing. Shortness of breath. Chest tightness. Unconciousness. Symptoms may be delayed. See Notes.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Watering of the eyes. Redness.  Wear safety spectacles, 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 refer for medical attention. 
Ingestion Abdominal pain. Headache. Nausea. Vomiting.  Do not eat, drink, or smoke during work.  Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
COLOURLESS CRYSTALS. TECHNICAL-GRADE PRODUCT: DARK BROWN LIQUID. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic fumes including arsenic and chlorine. Reacts with strong oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol. 

Inhalation risk
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. 

Effects of short-term exposure
The substance is irritating to the eyes and skin. The substance may cause effects on the nervous system. Exposure at high levels could cause lowering of consciousness. Inhalation of high levels of the aerosol may cause lung oedema. See Notes. The effects may be delayed. Exposure at high levels could cause death. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 333°C
Melting point: 38-44°C
Relative density (water = 1): 1.4 (45°C)
Solubility in water, g/100ml: 0.2 (poor)
Vapour pressure, Pa at 20°C: 0.06
Relative vapour density (air = 1): 9.15  
The substance is very toxic to aquatic organisms. 

NOTES
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation is therefore essential.
Card has been partly updated in April 2005.
