Sewer gases are a mixture of gases produced by the decomposition of organic matter in sewage systems. These gases can include methane, hydrogen sulfide, and ammonia, which can be harmful if inhaled in large quantities. They often escape from broken pipes or poorly sealed drains, leading to unpleasant odors and potential health risks. To prevent sewer gas buildup, proper ventilation and maintenance of plumbing systems are essential. Installing traps in drains can help block these gases from entering living spaces. Awareness of sewer gas symptoms, such as headaches or dizziness, is important for safety in homes and buildings connected to sewage systems.
