Module 1: Properties and Characteristics of Natural Gas

           MODULE 1: OVERVIEW


             Introduction         Natural gas is a gas, like air, — and is very different from liquid transportation fuels like
                                  gasoline and diesel. Because it is a gas, it behaves differently than other fuels and has
                                  properties and characteristics that are unique.

             Importance           Understanding the properties of natural gas will help you work on and around natural
                                  gas vehicles more safely.

             Module Overview      This module introduces you to the unique physical, chemical, combustion, emissions,
                                  and other properties of natural gas.  It will help you understand how natural gas
                                  compares to gasoline and diesel, and it will inform you about the safety hazards of
                                  natural gas and how to avoid them.

             Learning Objectives   ▪  Define natural gas and its origin
                                  ▪  Explain the properties and characteristics of natural gas
                                  ▪  Compare natural gas, gasoline, and diesel fuels
                                  ▪  Understand how natural gas is stored onboard vehicles
                                  ▪  Recognize the safety hazards of natural gas
