Major topics include: employee obligations, chain of command on a pipeline, general hazards and precautions, trench and excavation safety, soil testing and identification, potholing and underground utility lines, the duties of the various crews (fence, ditch, clearing, etc.), cleaning and inspecting pipes, and fabrication yards. Several of the topics require students to perform tasks or demonstrate skills being taught. Special emphasis is placed on following proper techniques, developing safe work habits, and recognizing unsafe work conditions.
