TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION Finely dispersed particles form explosive mixtures in air. Risk of explosion on contact with many substances.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.  In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position. 
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! AVOID EXPOSURE OF (PREGNANT) WOMEN!   
Inhalation Blue lips, fingernails and skin. Headache. Dizziness. Nausea. Confusion. Convulsions. Unconciousness.  Use local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin MAY BE ABSORBED! See Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes   Wear face shield.  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. Wash hands before eating.  Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. 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.

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-61S3454 or 61GT2-II.
NFPA Code: H3; F1; R3. 
Fireproof. Separated from strong bases, food and feedstuffs, oxidants and strong reducing agents. Well closed. Keep in a well-ventilated room. 

IMPORTANT DATA
Physical State; Appearance
YELLOW OR BROWN-TO-RED CRYSTALS WITH CHARACTERISTIC ODOUR. 

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

Chemical dangers
May explode on heating. Decomposes on heating. This produces toxic and corrosive fumes including nitrogen oxides even in the absence of air. Reacts with reducing agents, strong bases and oxidants. This generates explosion hazard. 

Occupational exposure limits
TLV: 0.2mg/m³ as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 2004).
MAK: Carcinogen category: 2; Skin absorption (H); (DFG 2004). 

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
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
The substance may have effects on the blood. This may result in formation of methaemoglobin. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
