Chemical Properties

Chlorthiophos is a yellowish-brown liquid. boiling point = 153-158°C @ 13 mmHg, and crystallizes at less than 25°C. Hazard identification (based on NFPA-704 M Rating System): Health 3, flammability 1, reactivity 0

Definition

ChEBI: Chlorthiophos is an organic thiophosphate.

General Description

Yellow-brown liquid which tends to crystallize at less than 77F. Used as an insecticide and acaricide.

Reactivity Profile

Organophosphates, such as Chlorthiophos, 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

Classified as extremely hazardous by the World Health Organization(Non-Specific -- Organophosphorus Pesticide) Organic phosphorus insecticides are absorbed by the skin, as well as by the respiratory and gastrointestinal tracts. They are cholinesterase inhibitors.

Fire Hazard

(Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) Container may explode in heat of fire.

Potential Exposure

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

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Speed in removing material from skinis of extreme importance. Shampoo hair promptly if contaminated. Seek medical attention immediately. If thischemical has been inhaled, remove from exposure, beginrescue breathing (using universal precautions, includingresuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.Effects may be delayed; keep victim under observation

storage

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working withChlorthiophos you should be trained on its proper handlingand storage. Store in tightly closed containers in a cool,well-ventilated area away from incompatible materials

Shipping

UN3018 Organophosphorus pesticides, liquid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials

Incompatibilities

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Strong oxidizers may cause release of toxic phosphorus oxides. Organophosphates, in the presence of strong reducing agents such as hydrides, may form highly toxic and flammable phosphine gas. Keep away from alkaline materials.

Waste Disposal

In accordance with 40CFR165 recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
