EMERGENCY OVERVIEW
Appearance: colorless
May cause irritation by all exposure routes.
Target Organs: none known.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation.
Ingestion:
May cause irritation of the digestive tract.
Material Safety Data Sheet
Hydrogen Sulfide Water

Inhalation:
Inhalation may cause pulmonary edema, weakness, coma, death.
Chronic:

Repeated inhalation may cause tissue damage, neurologic effects, digestive irritation, weight loss. Repeated skin
exposure may cause furunculosis.

Section 4 - First Aid Measures
Eyes:
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids until no evidence
of chemical remains. Get medical aid at once.
Skin:
