Excerpt from ERG Guide 140 [Oxidizers]:

CAUTION: Ammonium nitrate products may explode if involved in fire or contaminated with hydrocarbons (fuels), organic matter, other contaminants or when hot molten and contained. Treat as an explosive (GUIDE 112).

Excerpt from ERG Guide 140 [Oxidizers]:

· Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death.

A skin and eye irritant; Toxic by ingestion; May ignite in contact with organic matter or explode in contact with fuels; [CAMEO] 50% Aqueous solution: An oxidizer that may cause fire on contact with combustible materials; A skin and strong eye irritant; [Alfa Aesar MSDS] See Manganese and linked occupational diseases. See NITRATES and NITRITES.

Mixtures of metal/nonmetal nitrates with alkyl esters may explode, owing to the formation of alkyl nitrates; mixtures of nitrate with phosphorus, tin (II) chloride, or other reducing agents may react explosively [Bretherick 1979. p. 108-109]. The anhydrous nitrate salt with urea explodes upon heating, [Chem Abs., 1975, 82, 48151].
