Signs and Symptoms of EPTC Poisoning

NOTE! There may be other diseases and chemicals that have similar symptoms.

If you have a poisoning emergency in the United States call 1-800-222-1222.
If the victim has collapsed or is unconscious, call 911.

EPTC is a herbicidal Carbamate or Thiocarbamate compound.

Find Products Containing this Chemical

The herbicidal carbamates and thiocarbamates may be irritating to skin, eyes, and respiratory tract. Some may be weak inhibitors of cholinesterase, causing headache, dizziness, and nausea.

NOTE! PREVENT GENERATION OF MISTS! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!

Route of Exposure

Symptoms

First Aid
Inhalation Dizziness. Headache. Nausea. Fresh air rest. Refer for medical attention.
Skin Redness. Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes Redness. First rinse with plenty of water for several minutes (remove contact lenses if easily possible) then take to a doctor.
Ingestion (See Inhalation). Rinse mouth. Rest. Refer for medical attention.
Notes for ICSC Information
If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s). Carrier solvents used in commercial formulations may change physical and toxicological properties. The relation between odour and the occupational exposure limit cannot be indicated. Alirox Eptam Eradicane Genep Niptan Witox are trade names.

Indicates high toxicity in the given toxicological category. Indicates no available weight-of-the-evidence summary assessment. For additional information on toxicity from scientific journals or registration documents, see the "Additional Resources for Toxicity " section of the chemical detail page.
1. PAN Bad Actors are chemicals that are one or more of the following: highly acutely toxic, cholinesterase inhibitor, known/probable carcinogen, known groundwater pollutant or known reproductive or developmental toxicant. NOTE! Because there are no authoritative lists of Endocrine Disrupting (ED) chemicals, EDs are not yet considered PAN Bad Actor chemicals.
2. The acute toxicity reported on this page is of the pure chemical ingredient only and may not reflect the acute toxicity of individual pesticide products. To view acute toxicity of individual products, click on 'View Products' link in the 'Chemical Identification' section above.

HoneybeesSlightly ToxicSlightly Toxic
Note: Population-level effects on honeybees may occur even if a pesticide has low acute toxicity. For example, certain pesticides interfere with honeybee reproduction, ability to navigate, or temperature regulation, any of which can have an effect on long-term survival of honeybee colonies. The neonicotinoids, pyrethroids and keto-enol pesticides are some types of pesticides causing one or more of these effects.
Honeybee Chronic Toxicity

Any underlined term with a book icon has additional information.

* Data marked with an asterisk indicates that this chemical is not explicitly listed on the corresponding list. Instead, it belongs to a group of chemicals that IS designated on the list. For example, if an agency assigns a classification of reproductive toxicant to "mercury compounds", that classification is applied to all mercury compounds in the PAN Pesticide database, which are then marked with an asterisk.
