Usage

Description

Zinc phosphide, also known as trizinc diphosphide, is an amorphous gray-black powder with a garlic-like odor. It is practically insoluble in water (decomposes slowly), ethanol, slightly soluble in carbon disulfide, and benzene. It is a gray crystalline solid that is stable if dry, insoluble in alcohol, soluble in acids, and decomposes in water. Zinc phosphide is produced by heating finely powdered zinc with phosphorus.

Uses

Used in Pest Control Industry:
Zinc phosphide is used as a rodenticide and insecticide for controlling various species of rodents and insects. It is a highly effective and toxic compound due to its production of phosphine gas, which interferes with cell respiration in the target organisms.
Used in Agricultural Applications:
Zinc phosphide is used as a restricted use pesticide (RUP) in the agricultural industry. It is registered for use in EU countries and is effective in controlling rodents such as mice, ground squirrels, prairie dogs, voles, moles, rats, muskrats, nutria, and gophers. It can be used for indoor or outdoor spot treatments, around burrows or underground in orchards, vineyards, various food crops, rangelands, and non-crop areas.
Zinc phosphide is formulated as a bait/solid, dust, granular, pellet/tablet, or wettable powder and can also be applied as a broadcast treatment by ground or aerial applications.

Reactivity Profile

ZINC PHOSPHIDE is a reducing agent. They slowly generate flammable or noxious gases in contact with water. Phosphides react quickly upon contact with moisture or acids to give the very toxic gas phosphine; phosphides also can react vigorously with oxidizing materials. In general, materials in this group are incompatible with oxidizers such as atmospheric oxygen. They are violently incompatible with acids, particularly oxidizing acids.

Health Hazard

ZINC PHOSPHIDE is very caustic when ingested. ZINC PHOSPHIDE reacts with water and acid in the stomach and causes severe irritation. The probable oral lethal dose is 5-50 mg/kg, or between 7 drops and 1 teaspoonful for a 70 kg (150 lb.) person. Most patients die after about 30 hours from peripheral vascular collapse secondary to the compound's direct effects. Extensive liver damage and kidney damage can also occur. Ingestion of 4-5 grams has produced death in human adults, but also doses of 25 to 50 grams have been survived. The lowest oral lethal dose reported for women is 80 mg/kg.

Fire Hazard

When heated to decomposition, ZINC PHOSPHIDE emits toxic fumes of phosphorus and zinc oxides. Irritating oxides of phosphorus may be formed in fires. May ignite in presence of moisture. Contact with water produces flammable gas. Runoff to sewer may create fire or explosion hazard. Decomposed slowly by water giving off phosphine, a flammable poison gas. Reacts violently with concentrated sulfuric acid, nitric acid, and other oxidizing agents. Reacts with hydrochloric acid or sulfuric acid with the evolution of spontaneously flammable phosphine. May ignite in the presence of moisture, or evolve flammable gas. Stable unless exposed to moisture; toxic phosphine gas may then be released and collected in closed spaces. Hazardous polymerization may not occur.

Safety Profile

Human poison by ingestion causing nausea, vomiting, death. Flammable when exposed to heat or flame. This material is stable while kept dry. In moist air, it decomposes slowly. Reacts violently with acids or acid fumes to emit the hghly toxic and flammable phosphine. Violent reaction with concentrated sulfuric acid, nitric acid, and oxidzing materials. Incompatible with HCl, H2SO4. When heated to decomposition it emits toxic fumes of POx and ZnO. Used as an acute rodenticide. See also PHOSPHIDES and ZINC COMPOUNDS.

Potential Exposure

It is used as an acute single feeding rodenticide.

Shipping

UN1714 Zinc phosphide, Hazard Class: 4.3; Labels: 4.3-Dangerous when wet material, 6.1-Poisono us materials.

Incompatibilities

Dust may form explosive mixture with air. Heat and contact with water causes decomposition, producing toxic and flammable fumes of phosphorus, zinc oxides; and toxic and flammable phosphine gas. Reacts violently with strong acids, including nitric, hydrochloric acid or sulfuric acid with the evolution of spontaneously flammable phosphine gas. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact can cause fires or explosions. Keep away from alkaline materials, strong bases. carbon dioxide, halogenated agents.
