It occurs naturally in crude petroleum, natural gas, and hot springs. In addition, hydrogen sulfide is produced by bacterial break- down of organic materials and human and animal wastes (e.g., sewage).

Since hydrogen sulfide occurs as a gas in water, it can be physically removed by injecting air into the water and allowing the gas to escape. Aeration units may work by cascading, bubbling, or stripping the gas from the water. Aeration may be advantageous because it does not add chemicals to the water.

What Causes the Sulphur Smell in Well Water? The main reason for the smell is sulfur bacteria or hydrogen sulfide. Sulfur bacteria are found in environments that lack oxygen, like deep wells. You’ll also find such issues in areas having plumbing systems and organic matter.

Chlorine bleach can effectively remove medium to high levels (over 6 mg/l) of hydrogen sulfide. The chlorine in the bleach chemically reacts with (oxi- dizes) the hydrogen sulfide eliminating the “rotten egg” odor. Chlorine bleach also reacts with iron or manganese, and disinfects water supplies.

A rotten egg odor is a sign that the sulfur levels in your water may be too high. It’s understandable if you don’t want to drink or bathe in foul-smelling water, nor should you have to. Good, clean water is free of taste or odors and doesn’t pose any risks to your health.

At low levels, hydrogen sulfide causes irritation of the eyes, nose, and throat. Moderate levels can cause headache, dizziness, nausea, and vomiting, as well as coughing and difficulty in breathing. Higher levels can cause shock, convulsions, coma, and death.

Hydrogen sulfide

Death 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).

Hydrogen sulfide (H2S) is a colorless, flammable gas at ambient temperature and pressure. It has an odor similar to that of rotten eggs and is both an irritant and an asphyxiant. The air odor threshold ranges between 0.008 and 0.13 ppm, and olfactory fatigue may occur at 100 ppm.

Most gas passed during flatulence goes unnoticed because there isn’t a smell. It may contain odorless gases, such as nitrogen, oxygen, hydrogen, carbon dioxide and methane, but a small portion includes hydrogen sulfide, which causes it smell like rotten eggs.

H2S SAFETY TRAINING H2S Training is required in many industries including oil & gas, water treatment and seismic. This training program is intended to be completed entirely online.

one year

How much does h2s Alive cost? The cost of this course is 150 dollars plus tax= $157.50 . Candidates receive their credit card receipt by email. They have the option of receiving their written receipt at the class or online.

The certification period lasts for 1 year, at which point you will need to successfully pass the H2S exam again.

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 is a flammable, colorless gas with a rotten egg odor.

In workplaces where the possibility of H2S exposure exists, ALL workers should have H2S Awareness training. Workers who are at risk of exposure to H2S and/or workers with rescue responsibilities also require H2S Alive and workplace-specific training.

For the H2S Alive program, do I need to be clean shaven? » We would suggest that if you are participating in this program that you attend clean shaven however it is not required as part of the program.

1. Hydrogen sulfide is a chemical compound with the formula H.
2. Hydrogen sulfide is often produced from the microbial breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly known as anaerobic digestion which is done by sulfate-reducing microorganisms.
