Is hydrogen sulfide harmful to humans?
No health effects have been found in humans exposed to typical environmental concentrations of hydrogen sulfide (0.00011-0.00033 parts per million [ppm]).
Exposure to low concentrations of hydrogen sulfide may cause irritation to the eyes, nose, or throat.
It may also cause difficulty in breathing for some asthmatics..
How quickly does hydrogen sulfide kill?
1 to 4 hoursDeath can occur within 1 to 4 hours of exposure. Above 500 Immediate loss of consciousness. Death is rapid, sometimes immediate. H2S levels of 100 ppm and higher are considered immediately dangerous to life and health (IDLH).
Is hydrogen sulfide safe to drink?
However, it is highly unlikely that a person could consume a harmful dose of hydrogen sulfide from drinking water because water becomes unpalatable due to its unpleasant taste and odor long before hydrogen sulfide reaches a harmful level. In well water, it is usually just a nuisance.
Is the rotten egg smell from a battery dangerous?
Over-charging a lead acid battery can produce hydrogen sulfide. The gas is colorless, very poisonous, flammable and has the odor of rotten eggs. … As a simple guideline, hydrogen sulfide becomes harmful to human life if the odor is noticeable.
At what levels does hydrogen sulfide gas begin to be potentially fatal?
H2S is immediately fatal when concentrations are over 500-1000 parts per million (ppm). Hence, H2S has been referred to as the “knock down gas” because inhalation of high concentrations can cause immediate loss of consciousness and death.
How does hydrogen sulfide affect the body?
H2S irritates the mucous membranes of the body and the respiratory tract, among other things. Following exposure, short-term, or acute, symptoms may include a headache, nausea, convulsions, and eye and skin irritation. Injury to the central nervous system can be immediate and serious after exposure.
How do you neutralize hydrogen sulfide?
When dealing with a hydrogen sulfide gas leak, the National Oceanic and Atmospheric Administration recommends using water to spray down the gas, then adding sodium bicarbonate to neutralize it.
What are the side effects of breathing in sewer gas?
The principal risks and effects associated with exposure are: Hydrogen sulfide poisoning. Exposure to low levels of hydrogen sulfide causes irritation of the eyes and respiratory tract. Other symptoms include nervousness, dizziness, nausea, headache, and drowsiness.
Can you die from hydrogen sulfide?
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.
Is pure hydrogen toxic?
Hydrogen isn’t poisonous, but if you should breathe pure hydrogen you could die of asphyxiation simply because you’ll be deprived of oxygen. … Because it’s highly compressed, liquid hydrogen is extremely cold. If it should escape from its tank and come in contact with skin it can cause severe frostbite.
Is sewer gas harmful to your health?
Hydrogen sulfide is dangerous even at low levels. Prolonged exposure to sewer gas can cause irritability, headaches, fatigue, sinus infections, bronchitis, pneumonia, loss of appetite, poor memory and dizziness. It affects people and pets that are exposed to it over a long period of time.
Can you smell hydrogen sulfide?
People can smell the “rotten egg” odor of hydrogen sulfide at low concentrations in air. However, with continuous low-level expo- sure, or at high concentrations, a person loses his/her ability to smell the gas even though it is still present (olfactory fatigue).
What do you do if you smell rotten eggs?
If you smell rotten eggs in the home, call the gas company to make sure you don’t have a gas leak. If there is no gas leak in the home, you may have a problem with your electrical system. If you smell the rotten egg smell near an outlet, that’s probably where it is coming from.
How do you test for hydrogen sulfide?
Lead acetate test strips are a cheap & simple method of hydrogen sulfide detection in both water & air. Simply dip in water & check for a color change. To measure H2S gas in air, wet the strip first; if present, the strip will change color.
Can sewer gas explode?
Methane and hydrogen sulfide are explosive components of sewer gas. Vapors from improperly disposed fuel can further increase the risk of fire or explosion; and. odor. Hydrogen sulfide is responsible for sewer gas’s characteristic rotten-egg smell, which can be overbearing even at extremely low concentrations.
How do you fix sewer gas smell?
DIY Shower Drain Sewer Smell RemovalPour 1/4 cup of baking soda into the drain.Follow with one cup of white vinegar.Let that sit for two hours with the bathroom door closed.Slowly pour a gallon of hot water down the drain.After fifteen minutes, run cold water for ten minutes to thoroughly rinse the vinegar down.More items…•
How do you remove hydrogen sulfide from air?
2,168,933 teaches that hydrogen sulfide can be removed from technical gases such as water gas by the use of activated carbon with the addition of small amounts of air and ammonia.
What happens if you inhale hydrogen sulfide?
Symptoms of acute exposure include nausea, headaches, delirium, disturbed equilibrium, tremors, convulsions, and skin and eye irritation. Inhalation of high concentrations of hydrogen sulfide can produce extremely rapid unconsciousness and death. Exposure to the liquified gas can cause frostbite injury.
Why does my gas smell like a sewer?
Hydrogen sulfide gas is also known as “sewer gas” because it is often produced by the breakdown of waste material. At low levels, hydrogen sulfide gas has a strong odor similar to rotten eggs.
At what temperature does hydrogen sulfide become explosive?

How long does it take to die from hydrogen sulfide?
30-60 minutesStaggering, collapse in 5 minutes. Serious damage to the eyes in 30 minutes. Death after 30-60 minutes. Rapid unconsciousness, “knockdown” or immediate collapse within 1 to 2 breaths, breathing stops, death within minutes.
