Terminal Objective:

Upon completion of this module, the learner will be able to explain the DOT rules governing Accidental Ignition Sources of Natural Gas and describe the steps necessary to eliminate or minimize these dangers.

Enabling Objectives:

1. Define the fire triangle elements
2. Explain the requirements of DOT regulation 192.751 “Prevention of Accidental Ignition of Natural Gas.”
3. List four common ignition sources for escaping natural gas:
   1. Hot work (welding/cutting)
   2. Open flames (smoking)
   3. Static electricity
   4. Internal combustion engines
4. Describe actions that can be taken to reduce the buildup and/or discharge of static electricity on natural gas piping.
5. Define hot cutting and welding as it applies to natural gas piping.
6. Define cold cutting and welding as it applies to natural gas piping.
7. Explain the safety precautions to be taken when hot welding or cutting.
8. Explain the safety precautions to be taken when cold welding or cutting.
9. Describe how to isolate pipeline segments to minimize the potential of accidental ignition of natural gas.
