TYPES OF HAZARD
|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE-FIGHTING|
|FIRE||Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.||NO contact with combustible substances or reducing agents.||Use water in large amounts. NO other agents. In case of fire in the surroundings, use appropriate extinguishing media.|
|EXPLOSION||Risk of fire and explosion on confinement and exposure to high temperatures or when contaminated with other materials.||See Notes.||In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.|
|EXPOSURE||PREVENT DISPERSION OF DUST!|
|Inhalation||Cough.||Use local exhaust or breathing protection.||Fresh air, rest. Seek medical attention if you feel unwell.|
|Skin||Redness.||Protective gloves.||Rinse skin with plenty of water or shower. Remove contaminated clothes.|
|Eyes||Redness. Pain.||Wear safety goggles.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Vomiting. Diarrhoea. Blue lips, fingernails and skin. Weakness.||Do not eat, drink, or smoke during work.||Rinse mouth. Refer for medical attention .|
|PACKAGING & LABELLING|
|Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered non-combustible containers. Store and dispose of according to local regulations. Wash away remainder with plenty of water.||
UN Hazard Class: 5.1; UN Pack Group: III

Occupational exposure limits
Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion.
Effects of short-term exposure
Effects of long-term or repeated exposure
|PHYSICAL PROPERTIES||ENVIRONMENTAL DATA|
Decomposes at > 210°C
Melting point: 170°C

|Avoid release to the environment in circumstances different to normal use.|
UN number 1942 refers to pure ammonium nitrate with not more than 0.2% combustible material.
Ammonium nitrate can refer to a range of ammonium nitrate-based fertilizers (with UN number 2067).
The physico-chemical properties may vary according to the chemical composition.
This ICSC covers pure ammomium nitrate - the properties of fertilizers will be different.
Becomes shock-sensitive when mixed with organic materials.
Rinse contaminated clothing with plenty of water because of fire hazard.
Depending on the degree of exposure, periodic medical examination is suggested.
The storage of pure ammonium nitrate is often regulated - check for local regulations.
In the event of a fire, large piles of ammonium nitrate present an explosion hazard. Large piles might need to be dismantled.
