	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	PREVENTION	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

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.	Formula: NH₄C₆H₂N₃O₇ Molecular mass: 246.14 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

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.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
