Is natural gas considered poisonous?

Natural gas is primarily composed of methane, which is generally not considered poisonous. It is a colorless and odorless gas, and it poses minimal health risks in typical concentrations. Instead, it's important to note that natural gas is highly flammable and can create explosive mixtures with air, which is a significant safety concern.

While natural gas itself does not have toxic properties, the situation changes if it is burned improperly, as it can lead to the production of carbon monoxide, a toxic gas. However, in its natural state and at normal levels found in the environment, natural gas does not exhibit poisonous characteristics. Thus, characterizing it as non-poisonous aligns with this understanding.
