  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Many reactions may cause fire or explosion. See Notes.  Risk of explosion on shock or on friction. Risk of explosion on contact with reducing agents.  NO open flames.  Do NOT expose to friction or shock.  Use water in large amounts, water spray, powder, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
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 CLASSIFICATION & LABELLING
Consult an expert! Evacuate danger area! Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. 

According to UN GHS Criteria

explexcl mark;warn
DANGER

AMMONIUM PICRATE ICSC: 1631
PHYSICAL & CHEMICAL INFORMATION

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.

EXPOSURE & HEALTH EFFECTS

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

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. 

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

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


Occupational exposure limits
 

ENVIRONMENT
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.
