Hydrogen Sulfide is toxic because it can cause the inhibition of the cytochrome oxidase enzyme system resulting in lack of oxygen use in the cells.
Hydrogen sulfide is a highly flammable, explosive gas, and can cause possible life-threatening situations if not properly handled.
In addition, hydrogen sulfide gas burns and produces other toxic vapors and gases, such as sulfur dioxide.
Hydrogen Sulfide is poison and is highly toxic to humans and animals.
Exposure to hydrogen sulfide can cause irritation to the eyes and respiratory system. It can also cause apnea, coma, convulsions; dizziness, headache, weakness, irritability, insomnia; stomach upset, and if liquid: frostbite.
Workers may be harmed from exposure to hydrogen sulfide.
Hydrogen sulfide is a highly toxic gas that can produce extremely rapid CNS and respiratory depression.
It is also an irritant affecting skin and mucous membranes.
There is no proven antidote for hydrogen sulfide poisoning.
H2S is immediately fatal when concentrations are over 500-1000 parts per million (ppm) but exposure to lower concentrations, such as 10-500 ppm, can cause various respiratory symptoms that range from rhinitis to acute respiratory failure.
You can smell hydrogen sulfide gas at lower levels than may cause health effects, so smelling the gas does not always mean that it will make you sick.
However, at higher levels, your nose can become overwhelmed by the gas and you cannot smell it.
Effects of exposure to high levels (100 ppm or higher) of hydrogen sulfide can be serious and life-threatening.
Effects include shock, convulsions, inability to breath, rapid unconsciousness, coma, and death.
Hydrogen sulfide (H₂S) is a colorless gas with a strong odor of rotten eggs.
Exposure to hydrogen sulfide may cause irritation to the eyes and respiratory system.
It can also cause apnea, coma, convulsions; dizziness, headache, weakness, irritability, insomnia; stomach upset, and if liquid: frostbite.
Hydrogen sulfide's can cause inhibition of the cytochrome oxidase enzyme system resulting in lack of oxygen use in the cells.
Anaerobic metabolism causes accumulation of lactic acid leading to an acid-base imbalance.
Symptoms of acute exposure include nausea, headaches, delirium, disturbed equilibrium, tremors, skin and eye irritation, and convulsions.
Inhaling high concentrations can produce extremely rapid unconsciousness and death.
