Exposure

In the past, exposure of humans to heptachlor was directly related to the application of heptachlor as an insecticide. However, because of its the persistence and bioaccumulation, exposure of the general population can occur through ingestion of contaminated food (especially cow or human milk), inhalation of vapors from contaminated soil and water, or direct contact with residual heptachlor from pesticide application. People whose homes have been treated with heptachlor may continue to be exposed to these chemicals in the air over long periods. Occupational exposure can occur in the manufacture of the chemical or from use of heptachlor to control fire ants. Since heptachlor can volatilize from soil, people living near hazardous waste sites may be exposed to it in the air. People, whose homes have been professionally treated for termites, either by spraying or subsurface injection, may continue to be exposed to heptachlor and possibly to its transformation product, in the indoor air over long periods. Releases can also occur from the use of existing stocks in the possession of homeowners.

NOTE! PREVENT DISPERSION OF DUST! STRICT HYGIENE!General First Aid: IN ALL CASES CONSULT A DOCTOR!
Route of ExposureSymptomsFirst Aid
InhalationConvulsions TremorFresh air rest. Refer for medical attention.
SkinMAY BE ABSORBED! (See Inhalation)Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
EyesFirst rinse with plenty of water for several minutes (remove contact lenses if easily possible) then take to a doctor.
Ingestion(See Inhalation)Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention.

Notes for ICSC Information

Other melting points: 4674C for the technical product. Depending on the degree of exposure periodic medical examination is suggested. Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home.
