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. Many reactions may cause fire or explosion. See Notes.  NO open flames.  Use water in large amounts, water spray, powder, carbon dioxide. 
EXPLOSION Risk of explosion on shock or on friction. Risk of explosion on contact with reducing agents.  Do NOT expose to friction or shock.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Burning sensation. Cough. See Ingestion.  Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness. Roughness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain. Blurred vision.  Wear safety goggles.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer for medical attention. 
Ingestion Abdominal pain. Diarrhoea. Headache. Dizziness. Nausea. Vomiting. Weakness. Red urine.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING

Transport Emergency Card: TEC (R)-10G1.1.  Separated from incompatible materials. See Chemical Dangers. Store in an area without drain or sewer access. 

IMPORTANT DATA
Physical State; Appearance
RED OR YELLOW CRYSTALS. 

Physical dangers
 

Chemical dangers
May decompose on shock, friction or concussion. May explode on heating. On combustion, forms toxic gases including nitrogen oxides. Reacts with metals and reducing agents. This generates fire and explosion hazard. Reacts with concrete and plaster. This produces salts of picric acid, more sensitive to shock than ammonium picrate. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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 irritating to the skin and eyes. The substance may cause effects on the blood. This may result in destruction of blood cells and acidosis. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 265°C
Density: 1.72 g/cm³
Solubility in water, g/100ml at 20°C: 1.1
Octanol/water partition coefficient as log Pow: -1.4  
The substance is harmful to aquatic organisms. 

NOTES
For safety transportation, 10-20% water is usually added.
In normal conditions: combustible; if oxidized may become explosive.
Other UN number is 1310, with not less than 10% water by mass, hazard class 4.1, packing group I.
