TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames, NO sparks and NO smoking. NO contact with acids or water.  Use dry powder, carbon dioxide, dry sand. NO water. 
EXPLOSION Risk of fire and explosion on contact with water. Finely dispersed particles form explosive mixtures in air.  Do NOT expose to friction or shock. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust. Use non-sparking handtools.   
 
EXPOSURE   PREVENT DISPERSION OF DUST!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Severe deep burns.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Nausea. Vomiting. Abdominal pain.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Remove all ignition sources. Sweep spilled substance into covered dry, sealable containers. Do NOT let this chemical enter the environment.

IMPORTANT DATA
Physical State; Appearance
YELLOW-TO-GREEN CRYSTALS WITH CHARACTERISTIC ODOUR. 

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air. 

Chemical dangers
Reacts with bases, organic compounds and strong oxidants. Reacts violently with water and acids. This produces hydrogen sulfide (see ICSC 0165) and phosphoric acid (see ICSC 1008). This generates fire and explosion hazard. May decompose explosively on shock, friction or concussion. 

Occupational exposure limits
TLV: 1 mg/m³ as TWA; 3 mg/m³ as STEL; (ACGIH 2004). 

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed. 

Effects of short-term exposure
The substance is corrosive to the eyes. The substance is severely irritating to the skin and respiratory tract. 

Effects of long-term or repeated exposure
