DOT-Kennzeichnung	Poison
Brandgefahren	When heated to decomposition, it can emit toxic fumes of oxides of nitrogen, phosphorus, and sulfur. High pressure hoses may scatter material from broken containers. Containers may explode when heated. Stable in distilled water and in acid solution. Store below 77-86F. It slowly decomposes in air and hydrolyzes in the presence of alkaline material. Containers may explode when heated. (EPA, 1998)
