-
使用
Ammonium sulfamate (AMS) is an inorganic herbicide used for control of woody plants and herbaceous perennials.
-
一般的な説明
Ammonium sulfamate is a white crystalline solid. Ammonium sulfamate is soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Ammonium sulfamate is used to flameproof fabrics and papers, in weed or brush killing products, and for other uses.

火災危険
Special Hazards of Combustion Products: Toxic oxides of nitrogen may form in fires.
-
安全性プロファイル
Moderately toxic by
ingestion and intraperitoneal routes.
Somewhat explosive when heated or by
spontaneous chemical reaction in a hot acid
solution. A powerful oxidizer. When heated
to decomposition it emits very toxic fumes
of NH3, NOx, and SOx. See also
SULFONATES and SULFAMIC ACID.

廃棄物の処理
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations governing
storage, transportation, treatment, and waste disposal.
Dilute with water, make neutral with acid or base and flush
into sewer with more water.
