Usage

Description

PHOSFOLAN is a colorless to yellow solid organophosphorus insecticide, known for its effectiveness in controlling pests. It is characterized by its susceptibility to form highly toxic and flammable phosphine gas when in contact with strong reducing agents such as hydrides. Additionally, PHOSFOLAN decomposes upon heating, releasing toxic gases and vapors, including CO, NOx, SOx, and Pox. It does not undergo hazardous polymerization reactions, but partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. PHOSFOLAN is also hydrolyzed by alkalis.

Uses

Used in Agriculture:
PHOSFOLAN is used as an insecticide for controlling pests in various crops, helping to protect plants and ensure a healthy yield.
Used in Residue Analysis:
PHOSFOLAN has been identified and determined to be a residual pesticide in certain food samples, such as okra. This highlights its importance in residue analysis to ensure food safety and quality.
Used in Insect Control:
PHOSFOLAN is used as an insecticide for the control of insects, preventing damage to crops and maintaining agricultural productivity.

Air & Water Reactions

Hydrolyzed by alkalis. [EPA, 1998].

Reactivity Profile

Organophosphates, such as PHOSFOLAN, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.

Health Hazard

Similar to parathion. Death may result due to respiratory arrest as a result of paralysis of respiratory muscles and intense bronchoconstriction. Also considered a cholinesterase inhibitor.

Fire Hazard

(Non-Specific -- Organophosphorus Pesticide, n.o.s.) PHOSFOLAN may burn but does not ignite readily. Container may explode in heat of fire. When heated to decomposition, PHOSFOLAN emits very toxic fumes of oxides of phosphorus, sulfur, and nitrogen. Hydrolyzed by alkalies.

Safety Profile

Poison by ingestion and skin contact. An insecticide used against leaf-feeding larvae of cotton insect pests. When heated to decomposition it emits very toxic fumes of POx, SOx, and NOx. See also ESTERS

Potential Exposure

An organophosphate, A potential danger to those involved in the manufacture, formulation and application of this insecticide.

Shipping

UN3464 Organophosphorus compound, solid, toxic, n.o.s, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN2783 Organophosphorus pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Incompatibilities

Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrideds and active metals. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides Incompatible with nitrates and water. May hydrolyze upon contact with water, steam and moisture, and produce toxic oxides of phosphorus, nitrogen, sulfur, and chlorine
