Hazards

Reactivity Alerts
Air & Water Reactions
Soluble in water.
Fire Hazard
Special Hazards of Combustion Products: Toxic and irritating oxides of nitrogen may form in fires.

Behavior in Fire: Will increase intensity of fire when in contact with combustible material. Containers may explode. (USCG, 1999)
Health Hazard
Inhalation causes irritation of nose and throat. Contact with eyes causes irritation. (USCG, 1999)
Reactivity Profile
AMMONIUM NITRATE FERTILIZER, WITH AMMONIUM SULFATE is an oxidizing agent. Does not itself readily burn, but accelerates the burning of combustible material with which it may be contaminated. Produces toxic oxides of nitrogen during such reactions [© AAR, 1999]. Mixtures with alkyl esters may explode, owing to the formation of alkyl nitrates. Mixtures with phosphorus, tin(II) chloride or other reducing agents may react explosively [Bretherick 1979 p. 108-109]. Mixtures with aluminum powder (also zinc, cadmium, copper, magnesium, lead, cobalt, nickel, bismuth, chromium, and antimony) can be used as explosives. A number of explosions in which ammonium nitrate and aluminum were mixed with carbon or hydrocarbons, with or without oxidizing agents have occurred [Mellor 5:219 1946-47]. Mixtures with acetic acid ignite when warmed, especially if concentrated [Von Schwartz p. 322 1918]. Causes the decomposition of sodium hypochlorite within a few seconds [Mellor 2 Supp. 1:550 1956].

AMMONIUM SULFATE is acidic in aqueous solution. When a little ammonium sulfate is added to fused potassium nitrite, a vigorous reaction occurs attended by flame [Mellor 2:702 1946-47].

Response Recommendations

Firefighting
Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. (AAR, 2003)
Non-Fire Response
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Water spill: Use natural barriers or oil spill control booms to limit spill travel. Use natural deep water pockets, excavated lagoons, or sand bag barriers to trap material at bottom. Remove trapped material with suction hoses. (AAR, 2003)
Protective Clothing
Self-contained breathing apparatus must be used when fighting fires. At other times a dust mask is adequate. (USCG, 1999)
First Aid
INHALATION: move to fresh air.

EYES: flush with water for 15 min. (USCG, 1999)
