Fire while working on a gas line

A fire erupted when persons were working in a hole (pit) on gas line. A person with minor burns on face and hands went to hospital. The flames caused damaged to electric lines above.
It is reported that the crew searched for nearby shutoff valve to stop the fire. It appears that the crew did not do their job hazard analysis properly. Whether any safety permit is taken also is not clear.
This work, ie. working on a gas line that too in a pit is nothing but a confined space work and also working on line filled with gas.
One should have stopped gas flow and evacuated the line with inert gas before start of work. For safety, slip plate also should be inserted on either ends of the gas line to avoid passing or accidental flow. Emergency plan also should be in place which prepares the persons involved what to do in real emergency situation.
Searching for shutoff valve only indicates poor planning.
