Section lll. Hazards Identification
POTENTIAL ACUTE HEALTH May interfere with the oxygen carrying capacity of the blood if ingested in large quantities or over a
EFFECTS prolonged period of time. Persons with anemia, bowel diseases, or infants, are more likely to develop
effects. Over-exposure by ingestion is unlikely under normal working conditions. Inhalation of dusts may
cause respiratory irritation. This product may irritate eyes and skin upon contact but is unlikely to injure
tissue.
Symptoms of overexposure may include:
鈥? Cardiovascular: methemoglobinemia, low blood pressure (hypotension), irregular heart beat
(arrhythmia), shock (vasodilation)
鈥? CNS: headache, dizziness, generalized tingling sensation (paresthesia)
鈥? Gastrointestinal: nausea, vomiting, diarrhea, abdominal pain
鈥? Eye: redness and inflammation (conjunctivitis)
鈥? Skin: bluish discoloration (cyanosis) with profuse sweating following ingestion or irritation and
flushed skin following contact with moist skin surfaces.

HEALTH EFFECTS MUTAGENIC EFFECTS: NONE by ACGIH, EPA, IARC, NTP, OSHA.
TERATOGENIC EFFECTS: NONE by ACGIH, EPA, IARC, NTP, OSHA.
Repeated or prolonged overexposure by ingestion can reduce the oxygen carrying capacity of the blood
producing anoxia in infants or individuals with preexisting bowel or blood diseases. Ensure that nitrate
containing fertilizers are not applied near wells where contamination may occur. Consult your agronomist
regarding the advisability and precautions for use of nitrate fertilizers on fruit or vegetable crops.

FIRE HAZARD IN THE
PRESENCE OF VARIOUS
SUBSTANCES
EXPLOSION HAZARD IN THE Oxidizer: Material is an oxidizer which may react readily with other materials, especially upon heating.
PRESENCE OF VARIOUS
SUBSTANCES In confinement and in the presence of a strong detonation source, the material can explode when
subject to sudden shock, pressure, or high temperature. Avoid temperatures above 210掳C (410 OF)
which may cause thermal decomposition or explosion, especially in confined or poorly ventilated spaces.
Incompatible with sulfur, chlorides, reducing agents, or other oxidizers.
Incompatible with finely powdered metals (cadmium, copper, lead, cobalt, nickel, bismuth, chromium,
magnesium, zinc, sodium, potassium and aluminum).

build-up, or explosion. Establish unmanned monitors and apply flooding quantities of water. Withdraw to
INSTRUCTIONS
a safe location. Evacuate surrounding area. Material will not burn. Undergoes thermal decomposition at
elevated temperatures to release toxic and combustible gases (ammonia, carbon dioxide, and oxides of
nitrogen). If fumes or gases are present, fire fighters should wear self contained breathing apparatus.
Material supports combustion. Powerful oxidizing agent supports combustion by liberating oxygen even

if smothered. Avoid temperatures above 210掳C (410掳F) in confined or poorly ventilated spaces.
HAZARDS
Explosive when exposed to heat or flame under confinement. Avoid pressure build-up. Thermal
decomposition or explosion may result. Ventilate to cool and flood with water to stop decomposition
reaction. Contain and collect all runoff for treatment. Prevent fire water from reaching water courses or
aquifers.

Section V. Fire and Explosion Data
Industry studies have proposed the following rules for blends of ammonium nitrate with phosphate and
SPECIAL REMARKS ON
potassium containing fertilizers:
EXPLOSION HAZARDS
a) Ammonium nitrate fertilizers are reported not to detonate unless the fertilizer contains at least 70%
ammonium nitrate, unless ammonium sulfate is present in the blend. Blended ammonium nitrate -
ammonium sulfate fertilizers may detonate with as little as 45% ammonium nitrate present.
b) It has been reported that it is desirable to keep the ammonium to nitrate ratio above 1.5 in fertilizer
blends in order to minimize toxic gas release during "cigar bum" fires.
c) "Cigar burn" is considered to be a hazard primarily when the ammonium nitrate content of a blend
is between 20-40%. Cigar burn is a rare phenomenon which requires the combustion of a separate
combustible material such as sulfur which can cause thermal decomposition of nearby ammonium
nitrate.
Note - Dry Ammonium Nitrate, of any grade, when contaminated with oil, charcoal, and other
organic substances and flammable liquids, should be considered an explosive, capable of
detonation by combustion, or by explosion of adjacent explosives.
Section Vl. Accidental Release Measures
SMALL SPILL Use appropriate tools to put the spilled solid in a convenient container for reuse or disposal.
LARGE SPILL In the event of a spill, prevent additional discharge of material, if possible to do so without hazard.
Prevent spills from entering sewers, watercourses, wells, etc. Product will promote algae growth which
may degrade water quality and taste. Notify downstream water users. Nitrate in potable drinking water
should be maintained below 10 mg/L. Will dissolve and disperse in water. Put the material into suitable
container for reuse or disposal.
Section Vll. Handling and Storage
Keep away from heat, combustible materials, and reducing agents. Avoid contact with skin and eyes. Do
PRECAUTIONS
not ingest or breathe dust. Take precautions against electrostatic discharges. Keep out of reach of
children. Keep away from food, drink and animal feed. Notify police and fire departments for assistance.
Comply with all federal, state and/or local rules and regulations in the use of Ammonium Nitrate.
Store in a dry, cool and well ventilated area. Keep away from food, drink and animal feeds. Keep away
STORAGE
from combustible materials. Keep away from incompatible materials. Do not blend or store in contact
with urea. Dry urea and dry ammonium nitrate will react together to produce a slurry.
Section Vlll. Exposure Controls / Personal Protection
Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels
ENGINEERING CONTROLS
below recommended exposure limits. If user operations generate dust, use ventilation to keep exposure
to airborne contaminants below the exposure limit.
The selection of personal protective equipment varies, depending upon conditions of use. Wear
PERSONAL PROTECTION
appropriate respiratory protection for dust/mist when ventilation is inadequate. A filtering face piece dust
mask is recommended for most applications if respiratory protection is needed. Where skin and eye
contact may occur as a result of brief periodic exposures, wear long sleeved clothing, coveralls,
chemical resistant gloves, and safety glasses with side shields.
Wash hands thoroughly after handling product. Do not contaminate food products. Equipment used in
handling the material must be thoroughly cleaned before repair or maintenance. Maintain a high
standard of housekeeping in storage and processing areas.
No additional information.
PERSONAL PROTECTION IN
CASE OF LARGE RELEASE
U.S. OSHA PEL: 5mg/m3 as particulate not otherwise regulated.

TOXICITY TO ANIMALS
before returning livestock to pasture. The product itself and its products of degradation are not harmful
under normal conditions of careful and responsible use.
Recent studies undertaken by the U.S. Government using Canadian and American databases have

determined that ammonium nitrate fertilizer does not demonstrate any risk of gastrointestinal cancer.
HUMANS
Ammonium Nitrate is an irritant substance and inhalation of vapor or dust can be expected to cause
INHALATION
irritation of the respiratory passages. It is considered unlikely that absorption of a sufficient quantity of
the compound to cause general poisoning could occur by this route if personnel are adequately
protected in dusty conditions.
Ammonium Nitrate may cause itching and other signs of irritation, delays healing and may cause
SKIN CONTACT
ulceration. Occasionally, individuals may exhibit sensitivity to Ammonium Nitrate and may develop an
urticarial rash.
Ammonium Nitrate dust or strong solutions of the salt cause eye irritation.
EYE CONTACT
Relatively large amounts of Ammonium Nitrate must be ingested to produce toxic effects. In humans, 6

to 12 grams daily in divided doses may cause nausea and vomiting, acidosis, and in some individuals,
methemoglobin formation.
Exposure can cause headache, stomach pains, vomiting and diarrhea. Produces methemoglobin which
