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. | [Hazardous Substances Data]
1314-84-7(Hazardous Substances Data) | [Toxicity]
LD50 in male, female rats (mg/kg): 12.00, 15.72 orally (Ming) |
| Hazard Information | Back Directory | [General Description]
ZINC PHOSPHIDE(1314-84-7) is a dark gray granular solid. ZINC PHOSPHIDE(1314-84-7) is slowly decomposed by water giving off phosphine, a flammable poison gas. ZINC PHOSPHIDE(1314-84-7) is toxic by ingestion. ZINC PHOSPHIDE(1314-84-7) is used in medicine and as a rat poison. | [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]
This compound 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. | [Potential Exposure]
It is used as an acute single feeding
rodenticide. | [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. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled get medical attention for
phosphine, remove from exposure, begin rescue breathing
(using universal precautions, including resuscitation mask)
if breathing has stopped and CPR if heart action has
stopped. Transfer promptly to a medical facility. When this
chemical has been swallowed, get medical attention for
phosphine poisoning. Give one tablespoonful of mustard in
a glass of warm water; repeat until vomit fluid is clear;
avoid use of all oils. Do not make an unconscious person
vomit. Medical observation is recommended for 24 to
48 hours after breathing overexposure, as pulmonary edema
may be delayed. As first aid for pulmonary edema, a doctor
or authorized paramedic may consider administering a corticosteroid
spray or other inhalation therapy.

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. | [Description]
Zinc phosphide, 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 [9, p. 967].
Zinc phosphide is produced by heating finely powdered
zinc with phosphorus (10). | [Chemical Properties]
Dark gray, gritty powder. Stable if dry. Insoluble in alcohol;
soluble in acids; decomposes in water. | [Chemical Properties]
Zinc phosphide is a gray crystalline solid. | [Waste Disposal]
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform to EPA regulations governing
storage, transportation, treatment, and waste disposal.
Vanadium pentoxide may be salvaged or disposed of in a
sanitary landfill. | [Uses]
Rodenticide. | [Uses]
Zinc phosphide has been used since the second world war, and is most commonly used as an effective insecticide and rodenticide. Zinc phosphide is highly toxic due to its production of phosphine gas, and can cause symptoms such as nausea, vomiting and dyspnea in those (animal or human) that are exposed. | [Agricultural Uses]
Rodenticide: A U.S. EPA restricted Use Pesticide (RUP).
Registered for use in EU countries
. Zinc phosphide reacts with the acidic conditions in the gut to form phosphine
gas, which interferes with cell respiration. The rodenticide
may be used to control many species of rodents, including mice, ground squirrels, prairie dogs, voles, moles, rats,
muskrats, nutria and gophers. It may be used as an indoor
or outdoor spot treatment for rodents as well as around
burrows or underground in orchards, vineyards, various
food crops, range lands, and non-crop areas. Zinc phosphide is formulated as a bait/solid, dust, granular, pellet/
tablet or wettable powder and is also applied as a broadcast
treatment by ground or aerial applications. | [Trade name]
