  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Finely dispersed particles form explosive mixtures in air. Risk of explosion on contact with many substances.  NO open flames.  Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.  Use water spray, powder, foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position. 

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Blue lips, fingernails and skin. Headache. Dizziness. Nausea. Confusion. Convulsions. Unconsciousness.  Use local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin MAY BE ABSORBED! Redness. Further see Inhalation.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes   Wear safety goggles.  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 CLASSIFICATION & LABELLING
Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. 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. 

According to UN GHS Criteria

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
YELLOW CRYSTALS WITH CHARACTERISTIC ODOUR. 

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

Chemical dangers
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. 

Formula: C6H3CH3(NO2)2 / C7H6N2O4
Molecular mass: 182.1
Decomposes at 250-300°C
Melting point: 59-61°C
Relative density (water = 1): 1.3 (liquid)
Solubility in water: very poor
Relative vapour density (air = 1): 6.28
Octanol/water partition coefficient as log Pow: 2.0 (calculated) 


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is mildly irritating to the skin. The substance may cause effects on the blood. This may result in the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated. 

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

Effects of long-term or repeated exposure
The substance may have effects on the blood. This may result in the formation of methaemoglobin. 


Occupational exposure limits
 

ENVIRONMENT
The substance is very toxic to aquatic organisms. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Do NOT take working clothes home.
UN number for molten form: UN1600, TEC (R) 61GT1-II.
