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.

Symptoms of Hydrogen sulfide Exposure from the International Chemical Safety Cards (ICSC)

Report a Poisoning
View full ICSC Cards: English   Español   Française   Chinese   Dutch   Finnish   German   Hungarian   Japanese   Swahili   Thai   Urdu  
NOTE! AVOID ALL CONTACT!
 General First Aid: IN ALL CASES CONSULT A DOCTOR!

Route of Exposure

Symptoms

First Aid
Inhalation Cough. Dizziness. Headache. Laboured breathing. Nausea. Sore throat. Unconsciousness. Symptoms may be delayed (see Notes). Fresh air rest. Half-upright position. Artificial respiration if indicated. No mouth-to-mouth artificial respiration. Refer for medical attention.
Skin ON CONTACT WITH LIQUID: FROSTBITE. ON FROSTBITE: rinse with plenty of water do NOT remove clothes. Refer for medical attention.
Eyes Redness. Pain. Severe deep burns. First rinse with plenty of water for several minutes (remove contact lenses if easily possible) then take to a doctor.
Ingestion
Notes for ICSC Information
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. The odour warning when the exposure limit value is exceeded is insufficient.

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.
