EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use dry powder, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!   
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain.  Protective clothing. Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety spectacles or eye protection in combination with breathing protection if powder.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Blue lips, fingernails and skin. Confusion. Convulsions. Dizziness. Headache. Nausea. Abdominal pain. Vomiting. Unconsciousness.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .

PURPLE CRYSTALLINE POWDER OR NEEDLES 

Physical dangers
 

Chemical dangers
On combustion, forms toxic fumes of carbon monoxide and nitrogen oxides. Reacts with strong acids and strong oxidants. 

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
The substance is irritating to the skin and eyes. Ingestion could cause effects on the blood. This may result in formation of methaemoglobin. Medical observation is indicated. The effects may be delayed. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.
