As a natural gas apprentice, your job is to work your way through a training program and learn how to install, repair, and service natural gas systems. Most natural gas apprentices focus specifically on pipes and distribution systems rather than devices that use natural gas, though individual companies may teach different products. In this role, you may learn more about safety techniques, practice detecting leaks, and otherwise ensure that pipes have the correct fit. This job title refers exclusively to working with natural gas pipes and systems. It does not apply to drilling jobs that harvest natural gas from the ground.
