Indoor Air Quality Monitoring of Hydrogen Sulfide (H2S) ensuring H2S Safety
Hydrogen Sulfide (H2S) Monitoring ensuring H2S Safety
Following article lists sources of hydrogen sulfide causing indoor air pollution, why measurement of indoor hydrogen sulfide is necessary, harmful effects of hydrogen sulfide on human health and how indoor hydrogen sulfide is measured to ensure H2S safety.
It is colorless, highly poisonous, extremely toxic, potentially flammable gas, which has rotten egg odor. Hydrogen sulfide is a normal constituent of sewer gas. Hydrogen sulfide in buildings usually arise from dry drain traps or broken sewer lines. H2S safety must be ensure by fixing these. It may also be encountered in the production of gas crude oil, associated gas, and waters.
Indoor Hydrogen Sulfide can result cause harm to humans and create an unpleasant work environment. The level at which people can begin to smell the gas is about 0.01 ppm. So, care must be taken to keep lower levels and maintain H2S safety. Hydrogen sulfide is considered a broad-spectrum poison, which means that it can poison several different systems in the body, although the nervous system is most affected. This can be avoided by ensuring H2S safety.
It can affect various organs of the body as occupant’s nervous system can be poisoned. Long period of exposure can lead to fatigue, headache, irritability, dizziness etc. For H2S safety sewer system must robust. Exposure to lower concentrations can result in eye irritation, a sore throat and cough, nausea, shortness of breath, and fluid in the lungs. High exposure can even lead to respiratory paralysis as few minutes of breathing it occupants can feel loss of breathing. Inhalation at certain concentrations can lead to injury or death. Since hydrogen sulfide is heavier than air, it can collect in low places. So, H2S safety must be ensured in such places.
