What is Natural Gas
Natural gas is a highly combustible fossil fuel primarily composed of methane, along with various other hydrocarbons. Natural gas is invisible, odorless, tasteless, colorless, non-toxic, non-poisonous, and is lighter than air. Natural Gas can displace the oxygen in an enclosed spaced possibly causing suffocation. Austin Utilities adds a chemical called mercaptan to give it a rotten-egg scent to assist in detecting leaks, even in small quantities.
