Sewage gas can accumulate in septic tanks.
Sewage gas is a mixture of various gases that can form when household waste or other waste breaks down. Some of the gases that normally make up sewage gas, such as ammonia and hydrogen sulfide, are dangerously toxic. Sewage gas can accumulate in septic tanks, municipal sewers, and manure ponds. It can sometimes seep into the home through blocked or leaking drains, vents, and sewer pipes. When sewage gas contaminates the indoor air of a home, it can present a number of health hazards and can even be fatal in large amounts.
Exposure to toxic gases can cause memory problems, headaches, and irritability.
The gas mixture commonly known as sewage gas is usually a by-product of the decomposition of industrial or human waste. Hydrogen sulfide and ammonia can be the most toxic gases present in any sewer area. Other gases that can occur as a byproduct of waste decomposition include carbon dioxide, nitrous oxide, methane, and sulfur dioxide. Industrial waste can produce gaseous by-products such as chlorine during decomposition.
Some of those who work with sewage gases may be required to wear personal protective equipment.
Exposure to toxic gases can cause a number of health problems and can even be fatal. Small amounts of residual gases in indoor air can cause eye irritation, sore throat, cough, and pulmonary edema. Poor appetite, headaches, fatigue, dizziness, memory problems, and irritability can occur in people exposed to low levels of these gases for a longer period of time. Strong concentrations of this gas can cause loss of consciousness and eventually be fatal.
Sewage gas can cause eye irritation.
Sewer gas can usually be identified by its smell, which is said to be reminiscent of rotten eggs. However, strong concentrations of these gases can affect the sense of smell, making the stench of the gases impossible to detect. Generally, these gases are also extremely flammable.
Those who work in the maintenance and cleaning of sewers, septic tanks or manure tanks are more likely to be exposed to dangerous gases. This gas mixture can seep into a home’s indoor air if plumbing, drains, and vents are poorly maintained.
Breathing small amounts of sewage gas can cause a sore throat, among other symptoms.
Most homes have plumbing openings in the roof that allow gas to escape from the home’s plumbing system. Keeping these vents clear can help prevent sewer gas from seeping into your home. Properly maintaining and cleaning indoor drains and pipes can also prevent dangerous gases from escaping.
Homeowners who suspect a sewer gas leak are generally advised not to occupy their homes until the leak is resolved. Public health authorities and local fire departments may need to be notified of the problem. It is usually possible to hire a professional plumber to resolve the situation.
