Why Carbon dioxide is called asphyxiant gas?
Exposure Effects
Carbon dioxide (CO2) is a toxic gas at high concentration, as well as an asphyxiant gas (due to reduction in oxygen). Irritation of the eyes, nose and throat occurs only at high concentrations.
Is natural gas toxic to breathe?
However, natural gas is a flammable material. A natural gas leak in a house can cause potential fires, and inhaling the gas can cause natural gas poisoning. As with electricity, gasoline and other potentially dangerous energy sources, natural gas exposure must be handled with care.
Does sewer gas rise or sink?
Many of the components of sewer gas are heavier than air and tend to settle/accumulate in basements or the lower level of structures. The methane component is less dense than air and tends to rise in structures.
What does death by suffocation look like?
