TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! PREVENT DISPERSION OF DUST! STRICT HYGIENE!   
Inhalation Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Wheezing.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin Redness. Burning sensation. Pain.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Pain. Redness. Conjunctivitis.  Wear safety goggles 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 Abdominal cramps. Diarrhoea. Drowsiness. Nausea. Unconsciousness. Vomiting.  Do not eat, drink, or smoke during work. Wash hands before eating.  Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.  Do not transport with food and feedstuffs.

IMPORTANT DATA
Physical State; Appearance
YELLOW-TO-RED CRYSTALLINE POWDER OR SOLID IN VARIOUS FORMS. 

Physical dangers
No data. 

Chemical dangers
Upon heating, toxic fumes are formed. Decomposes on heating. This produces toxic fumes. Reacts with combustible substances. 

Occupational exposure limits
MAK: Carcinogen category: 2; Germ cell mutagen group: 2; (DFG 2006). 

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

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of short-term exposure
The aerosol is irritating to the eyes, skin and respiratory tract. Inhalation of high concentrations may cause lung oedema, bronchitis and bronchospasm. The effects may be delayed. 

Effects of long-term or repeated exposure
Repeated or prolonged inhalation of high concentrations of dust or fumes may cause effects on the lungs. The substance may cause a greenish-black discolouration of the tongue. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 1750°C
Melting point: 690°C
Relative density (water = 1): 3.4
Solubility in water, g/100ml: 0.8  
The substance is harmful to aquatic organisms. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
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 are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
