TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use water spray, powder. 
EXPLOSION   Prevent build-up of electrostatic charges (e.g., by grounding).   
 
EXPOSURE   PREVENT DISPERSION OF DUST! STRICT HYGIENE!   
Inhalation Abdominal pain. Blue lips, fingernails and skin. Confusion. Convulsions. Cough. Dizziness. Headache. Nausea. Sore throat. Unconciousness.  Use local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness. Pain.  Wear safety goggles, 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 See Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give a slurry of activated charcoal in water to drink. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
WHITE CRYSTALS. TURNS PINK ON EXPOSURE TO AIR AND LIGHT OR ON CONTACT WITH IRON. 

Physical dangers
As a result of flow, agitation, etc., electrostatic charges can be generated. 

Chemical dangers
Reacts with strong oxidants, ammonia and amino compounds. This generates fire and explosion hazard. 

Occupational exposure limits
TLV: 10 ppm as TWA; 20 ppm as STEL; A4 (not classifiable as a human carcinogen); (ACGIH 2003). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. 

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, skin and respiratory tract. The substance may cause effects on the blood. This may result in formation of methaemoglobin. The effects may be delayed. Medical observation is indicated. 

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