Elemental sulfur is considered to be of low toxicity. Compounds such as carbon disulfide, hydrogen sulfide, and sulfur dioxide are toxic. For example, at 0.03 parts per million, we can smell hydrogen sulfide but it is regarded as safe for eight hours of exposure. At 4 ppm it may cause eye irritatation. en A 1999 comparison of ambient air quality requirements for major air pollutants (e.g. sulphur dioxide, hydrogen sulphide, nitrogen dioxide, carbon monoxide, ground level ozone and total suspended particles) showed Alberta’s requirements are equivalent to or more stringent that those of other provinces and the United States.
Gas water heaters that release CO into the environment most likely have an issue with the venting of the exhaust, especially for atmospheric gas water heaters. Atmospheric gas water heaters draw combustion air from the space in which the appliance is installed and vents into exhaust piping or a chimney running vertically through the roof. Sulfur dioxide is released when compounds containing sulfur, such as fossil fuels like coal are burned. Sulfur dioxide is a highly toxic gas which poisons its victims via inhalation through the lungs. SO2 combines with water to form sulfuric acid (H2SO4). It is for this reason that sulfur dioxide can burn the respiratory tract upon inhalation.
Carbon dioxide, hydrogen sulfide, and other contaminants are often found in natural gas streams. CO2 when combined with water creates carbonic acid which is corrosive. CO2 also reduces the BTU value of gas and in concentrations of more that 2% or 3 % the gas is unmarketable. Dioxide*, Nitric Oxide*, Oxygen and Ozone. Remember to keep oxidizing materials away from flammable gasses. *Indicates a Toxic gas (NFPA health rating of 3 or 4) Pyrophoric gas A Pyrophoric gas is a flammable gas with an auto-ignition temperature in air at or below 1300° F (704° C). These gases may spontaneously combust in air.
Dec 02, 2016 · Natural gas that contains more than 4 ppmv of hydrogen sulphide (H2S) is commonly referred to as "sour". This is because the odour of hydrogen sulphide gas in air at very low concentrations is similar to that of rotten eggs.

Hydrogen sulfide can present dangerous problems in water treatment. Brief exposures (less than 30 minutes) to hydrogen sulfide can be fatal if the gas is breathed in concentrations as low as 0.03 percent by volume in the air. The Immediate Dangerous to Life and Health level for hydrogen sulfide is 300 ppm. Mar 18, 2013 · Hydrogen Sulfide gas (H2S) with its characteristic “rotten egg” taste and smell can actually be detected as an off smell at 0.5 parts per million (ppm) by most people. At less than 1 ppm, hydrogen sulfide will give water a musty odor. At 1 to 2 ppm, it will have an odor similar to rotten eggs.

Jul 17, 2018 · Sulphur dioxide (SO2)’s olfactory effect is much the same as elemental sulphur. Hydrogen sulphide (H2S) is formed by yeasts reducing sulphur by adding hydrogen ions. (Oxidation is the addition of oxygen ions while reduction is the opposite reaction, the removal of oxygen ions or addition of hydrogen ions.)

gas is burned, other toxic gases, such as sulphur dioxide are formed. Hydrogen sulphide is incompatible with strong oxidizers, such as nitric acid or chlorine trifluoride, and may react violently or ignite spontaneously. When hydrogen sulphide is released into the air, it will form sulphur dioxide and sulphuric acid in the atmosphere. Health effects

Jun 21, 2015 · In many oil and gas operations, hydrogen sulfide is flared to produce sulfur dioxide. Paradoxically, the threshold limit of SO2 is actually lower than that of H2S (20 PPM vs 10 PPM) and SO2 and H2S are actually Immediately Dangerous to Life and Health (IDLH) at equal concentrations (100ppm).

Flaring is the practice of burning gas that is deemed uneconomical to collect and sell. Flaring is also used to burn gases that would otherwise present a safety problem. It is common to flare natural gas that contains hydrogen sulfide (i.e., sour gas), in order to convert the highly toxic hydrogen sulfide gas into less toxic compounds. Hydrogen sulfide burns in oxygen with a blue flame to form sulfur dioxide (SO 2) and water. In general, hydrogen sulfide acts as a reducing agent, especially in the presence of base, which forms SH −. At high temperatures or in the presence of catalysts, sulfur dioxide reacts with hydrogen sulfide to form elemental sulfur and water.
