SECTION 4 - FIRST AID MEASURES
Description of First Aid Measures
General: Never give anything by mouth to an unconscious person. If you feel unwell, seek medical advice (show the label
where possible).
Inhalation: If symptoms occur, go into fresh air and ventilate suspected area. Seek medical attention.
Skin Contact: Remove contaminated clothing. Wash with soap and water followed by rinsing with water. Seek medical
attention if irritation develops or persists. Wash contaminated clothing before reuse.

SECTION 6 - ACCIDENTAL RELEASE MEASURES
Personal Precautions, Protective Equipment and Emergency Procedures
General Measures: Handle in accordance with good industrial hygiene and safety practice. Avoid breathing (dust, vapor,
mist, gas). Avoid getting in eyes or on skin. Keep away from combustible material.
For Non-Emergency Personnel
Protective Equipment: Use appropriate personal protection equipment (PPE).
Emergency Procedures: Evacuate unnecessary personnel.

fire and increasing risk of burns and
injuries. Smothering, contact with organic material, or combustible material may cause an explosive situation. Reactivity: May cause or intensify fire; oxidizer. May accelerate the burning of other combustible materials. Smothering,
contact with organic material, or combustible material may cause an explosive situation. Advice for Firefighters
Precautions for Firefighting: Evacuate the area for 1 mile if ammonium nitrate is involved in a fire. Only fires which
are in the initial or beginning stage or those involving minimal amounts of ammonium nitrate in a manufacturing setting or
in an area where ammonium nitrate is stored or in vehicles transporting ammonium nitrate should be attacked using
manual fire extinguishing methods (fire extinguishers, hose streams, etc.) that require a human operator. If a fire in an
area where ammonium nitrate is stored or in vehicles transporting ammonium nitrate progresses beyond the incipient
stage or involves the ammonium nitrate, evacuation is required. Fire fighters downwind from a fire should wear self-
contained breathing apparatus. Fire fighters must use standard protective equipment including flame retardant coat,
helmet with face shield, gloves and rubber boots. Hazardous Combustion Products: Nitrogen oxides. Toxic fumes are released. Carbon oxides (CO, CO2). Ammonia.

Safety Data Sheet
SECTION 5 - FIRE-FIGHTING MEASURES
Extinguishing Media
Suitable Extinguishing Media: Evacuate the area for 1 mile if ammonium nitrate is involved in a fire. Only water shall be
used on ammonium nitrate fires. Dry chemical, foams, steam and smothering devices are not effective and can lead to
possible explosion of the ammonium nitrate. General extinguishers may be used on fires not involving the ammonium
nitrate such as conveyors, electrical equipment, tires, bearings, general plant equipment or the like when only minimal
amounts of ammonium nitrate are present. For large fires use unmanned monitor nozzles if available. Unsuitable Extinguishing Media: Dry chemical, carbon dioxide, or regular foam. Special Hazards Arising From the Substance or Mixture In intense fires, the ammonium nitrate can melt and detonate
from confinement or strong shocks. Evacuation of at least 1 mile is recommended if the ammonium nitrate is involved in
a fire. Fire Hazard: May intensify fire; oxidizer. Will accelerate the burning of other combustibles, resulting in more rapid spread
of fire. Explosion Hazard: Heat may build pressure, rupturing closed containers, spreading fire and increasing risk of burns and
injuries. Smothering, contact with organic material, or combustible material may cause an explosive situation. Reactivity: May cause or intensify fire; oxidizer.

equipment including flame retardant coat,
helmet with face shield, gloves and rubber boots. Hazardous Combustion Products: Nitrogen oxides. Toxic fumes are released. Carbon oxides (CO, CO2). Ammonia. Additional Information: If a fire has not reached the ammonium nitrate, cool the ammonium nitrate or container thereof
to prevent the fire from reaching it. Ammonium nitrate does not burn by itself and thus needs to be kept separate from
combustible materials. Ammonium nitrate is an oxidizer and will significantly increase the burning rate of combustible
materials. When in confinement and in the presence of a strong detonation sources the material can explode when subject to
sudden shock, pressure, or high temperatures. Avoid temperatures above 210 C (410 F) which may cause thermal
decomposition or explosion, especially in confined or poorly ventilated spaces. Do not allow run-off from fire fighting to enter drains or water courses. Reference to Other Sections: Refer to section 9 for flammability properties. Not flammable.
