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.	Water in large amounts, water spray. Powder, carbon dioxide.
EXPLOSION	Risk of explosion on shock or friction and 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.	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.	Safety goggles.	First rinse with plenty of water (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.

AMMONIUM PICRATE

ICSC: 1631

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
RED OR YELLOW CRYSTALS.

CHEMICAL DANGERS:
May decompose explosively on shock, friction, or concussion. May explode on heating. On combustion, forms toxic gases including nitrogen oxides. Reacts violently with metals and reducing agents causing fire and explosion hazard. Reacts with concrete and plaster to produce salts of picric acid, more sensitive to shock than ammonium picrate.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK 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 the eyes. The substance may cause effects on the blood , resulting 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

Melting point (decomposes): 265°C
Density: 1.72 g/cmł
Solubility in water, g/100 ml at 20°C: 1.1.

Octanol/water partition coefficient as log Pow: -1.4

ENVIRONMENTAL DATA

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+II.
