SECTION 5 - FIRE-FIGHTING MEASURES
Extinguishing Media
Suitable Extinguishing Media: Water only or water spray. Do not attempt to smother. Do not use salt water, dry
chemical, carbon dioxide, steam or foam. Unsuitable Extinguishing Media: Dry chemical, carbon dioxide, or regular foam. Special Hazards Arising From the Substance or Mixture
Fire Hazard: May intensify fire; oxidizer. Will decompose if exposed to excessive heat, and in addition, 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 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
Precautionary Measures Fire: Hot AN solution may also ignite combustibles such as wood, paper, oil, clothing, etc. It
will support and increase the rate of combustion in the presence of flammable or combustible materials even in the
absence of oxygen. As it is an oxidizer, fires involving AN cannot be extinguished by conventional firefighting methods
that “smother” a fire by excluding oxygen (air).

an AN fire and one of the products of the
decomposition may be NOx fumes. These fumes are toxic. Therefore, positive pressure self-contained breathing
apparatus may be required when fighting AN fires. Protection During Firefighting: In the event of a fire, call the Emergency Fire and Rescue Service and consider
evacuation to a safe place where people are not exposed to the fumes or risk from explosion. The initial evacuation
distance in the event of a fire SHALL be established at least 1 mile/1600 meters from the storage building in all directions. Large Uncontrollable Fires: Massive or uncontrollable/accelerating fires that might involve heating AN under
confinement or involve highly reactive supporting fuels that could become intimately mixed with the AN SHALL not be

mbustible materials even in the
absence of oxygen. As it is an oxidizer, fires involving AN cannot be extinguished by conventional firefighting methods
that “smother” a fire by excluding oxygen (air). When heated it will melt, decompose and release toxic gases including
nitric acid vapor, nitrogen oxides (NOx) and ammonia gas (NH3). These gases can recombine as they cool, forming a
white cloud of AN fumes that is both confusing and a visibility issue for emergency responders. When heated excessively
(e.g. as in a fire) it can cause an explosion in an enclosed space and closed containers or vessels may rupture violently. Firefighting Instructions: Large quantities of water should be used when fighting fires involving AN. Dry chemicals,
CO2, halogen or foam should not be used. When using copious amounts of water, consideration should be given to the
firewater run-off to protect against possible water pollution. Electrical equipment, if involved, should be isolated before the
application of water. Several different AN decomposition reactions may be involved during an AN fire and one of the products of the
decomposition may be NOx fumes. These fumes are toxic. Therefore, positive pressure self-contained breathing
apparatus may be required when fighting AN fires.

ify authorities in accordance
with emergency response procedures. Only personnel trained in emergency response should respond. Follow applicable
federal, state, and local spill reporting requirements. Contact of this product with water may result in a reportable release. Contain any spills with dikes or absorbents to prevent migration and entry into sewers or streams. Clean up spills
immediately and dispose of waste safely. Will solidify upon cooling if not diluted, and may be suitable for reuse. Absorb
and/or contain spill with inert material, then place in suitable container. Contact competent authorities after a spill. Do not
take up with combustible material such as sawdust or cellulosic material. Reference to Other Sections
See heading 8, Exposure Controls and Personal Protection

SECTION 7 - HANDLING AND STORAGE

Safety Data Sheet
fought.
Controllable fires involving AN should be fought by trained personnel in accordance with site emergency planning.
Hazardous Combustion Products: When heated, Ammonium Nitrate will melt, decompose and release toxic gases
including nitric acid vapor, nitrogen oxides (NOx) and ammonia gas (NH3). These gases can recombine as they cool,
forming a white cloud of AN fumes that is both confusing and a visibility issue for emergency responders. When heated
excessively (e.g. as in a fire) it can cause an explosion in an enclosed space and closed containers or vessels may
rupture violently.
Other information: May explode or detonate under confinement and high temperatures. Ammonium nitrate emits toxic
nitrogen oxides when heated to decomposition and will release ammonia to air upon reaction with strong alkalis.
Explodes more readily if contaminated with organic materials or other fuels. 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.

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 (vapor, mist,

Protective Equipment: Use appropriate personal protection equipment (PPE). Emergency Procedures: Evacuate unnecessary personnel. For Emergency Personnel
Protective Equipment: Equip cleanup crew with proper protection. Use appropriate personal protection equipment
(PPE). Emergency Procedures: Ventilate area. Environmental Precautions
Prevent entry to sewers and public waters. Methods and Material for Containment and Cleaning Up
For Containment: Dike and contain spill. Notify authorities in accordance with emergency response procedures. Only
personnel trained in emergency response should respond. Contain with inorganic absorbents – do not use combustible
material such as sawdust or cellulosic material. Methods for Cleaning Up: Evacuate unnecessary personnel. Dike and contain spill. Notify authorities in accordance
with emergency response procedures. Only personnel trained in emergency response should respond. Follow applicable
federal, state, and local spill reporting requirements.
