Does mold smell like sewer gas?

Does mold smell like sewer gas?

Those are different. Mold may not smell at all, but you can see it. Sewer gas is that rotten egg smell, is rather distinctive, and you should NOT have that odor. If you do, look for an unused sink or floor drain where the trap may have dried out, or if there is an ejector sump, check for bad seals.

Can sewer gas cause mold?

Methane Gas (CH4) Adding to the discomfort of the smell, there is also the danger of poisonous gas. There are traces of methane gas that are found in the sewer smell. Methane gas is very dangerous because it can cause an explosion. Other than that, it can cause fatal asphyxiation (deprivation of oxygen).

Is hydrogen sulfide gas harmful?

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. Workers may be harmed from exposure to hydrogen sulfide.

Is hydrogen sulfide heavier than air?

It is flammable, colorless and noticeable by its rotten egg odor. Hydrogen sulfide is heavier than air, so it stays low to the ground. People can smell the specific odor at low concentrations in air ranging from 0.0005 to 0.3 parts per million (ppm).

How to detect hydrogen sulfide in the workplace?

This must be done by a qualified person. Use the right test equipment, such as an electronic meter that detects hydrogen sulfide gas. Conduct air monitoring prior to and at regular times during any work activity where hydrogen sulfide exposure is possible.

What does hydrogen sulfide smell like in the air?

Hydrogen sulfide is a flammable, colorless gas that smells like rotten eggs. People usually can smell hydrogen sulfide at low concentrations in air ranging from 0.0005 to 0.3 parts per million (ppm). Hydrogen sulfide occurs naturally in crude petroleum, natural gas, volcanic gases, and hot springs.

What can you do about hydrogen sulfide in the air?

Identify processes that could release or produce hydrogen sulfide. This includes identifying known sources of hydrogen sulfide and evaluating possible fire and explosion hazards. Use a Process or Job Hazard Analysis for identifying and controlling hazards. Test (monitor) the air for hydrogen sulfide. This must be done by a qualified person.

When do you need to test for hydrogen sulfide?

However, the detection of hydrogen sulfide or its metabolites cannot predict the kind of health effects that might develop from that exposure. Because hydrogen sulfide and its metabolites leave the body fairly rapidly, the tests need to be conducted soon after exposure.
