Hydrogen Sulfide (H2S) Hazards

Health Effects of Hydrogen Sulfide (H2S)

H2S is heavier than air and can collect in low-lying and enclosed, poorly ventilated areas such as basements, manholes, sewer lines and underground telephone/electrical vaults.

H2S Warning

1. Low concentrations – irritation of eyes, nose, throat, or respiratory system; effects can be delayed.

2. Moderate concentrations – more severe eye and respiratory effects, headache, dizziness, nausea, coughing, vomiting and difficulty breathing.

3. High concentrations – shock, convulsions, unable to breathe, coma, death; effects can be extremely rapid (within a few breaths).
