SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal and plant life; and conformance with environmental and public health regulations.

Incompatible with strong oxidizers, strong bases. Contact with air causes this chemical to produce anhydrous ammonia fumes.

The food additive diammonium phosphate may be safely used in ruminant feed in accordance with the following prescribed conditions: (a) The food additive is the product resulting from the neutralization of feeding-phosphoric-acid or defluorinated wet-process phosphoric acid with anhydrous ammonia. It contains not less than 106.25% equivalent crude protein (nitrogen X 6.25) and 20% phosphorus. It contains not more than the following: 1 part fluorine to 100 parts phosphorus; 75 ppm arsenic (as As); 30 ppm heavy metals, as lead (Pb). (b) It is used in ruminant feeds as a source of phosphorus and nitrogen in an amt that supplies not more than 2% of equivalent crude protein in the total daily ration.|Ammonium phosphate (mono-, and dibasic) used as a general purpose food additive in animal drugs, feeds, and related products is generally recognized as safe when used in accordance with good manufacturing or feeding practice.|Substance added directly to human food affirmed as generally recognized as safe (GRAS).

WHO; Diseases Caused by Phosphorus and Its Toxic Compounds; Early Detection of Occupational Diseases pg 53-62 (1986). Review of diseases and health related effects resulting from exposure to phosphorus or phosphorus cmpd.

Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
