Explosive reaction on heating with tetrahydrofuran. Mixtures with potassium chlorate and other metal oxohalogenates (e.g., chlorates; bromates; and perchlorates) are heat- and friction-sensitive explosives. Vigorous or incandescent reaction on heating with halogens (chlorine; bromine; or iodine); manganese dioxide; and silver halides (e.g., silver fluoride; silver iodide). See also CALCIUM COMPOUNDS and HYDRIDES.
Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. May produce corrosive solutions on contact with water. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution.
