Safety Description:Poison by ingestion, skin contact, intraperitoneal, and intramuscular routes. An experimental teratogen. Experimental reproductive effects. An FDA over-the-counter drug. Used for treating fruit trees. Flammable by chemical reactions. A powerful oxidizer. Explosive reaction with acetyl nitrate, butadiene + ethanol + iodine (at 35°C), chlorine + hydrocarbons (e.g., methane, ethylene), diboron tetrafluoride, hydrogen peroxide + traces of nitric acid, reducing agents (e.g., hydrazine hydrate, phosphinic acid). Forms heat- or impact-sensitive explosive mixtures with nonmetals (e.g., phosphorus, sulfur), metals (e.g., magnesium, potassium, sodium-potassium alloy). Reacts violently with hydrogen trisulfide (on ignition), hydrazine hydrate, hydrogen peroxide, hypophosphorous acid, iodine + methanol or ethanol, phospham, acetyl nitrate, S₂Cl₂, reductants. Incandescent reaction with phospham. When heated to decomposition it emits highly toxic fumes of Hg. See also MERCURY COMPOUNDS, INORGANIC.
