This is what happens when you dig up a gas main.The machine was wrecked and they couldnt put it completely out untill they turned off the gas about 2 hrs later.
where in australia did it happen
I was working with specialties in fort wayne, in about 8 or so years ago on I-69 when they hit a high pressure gas main while lime stabilizing the subgrade. The gas company installed the new line 4 inches below the final subgrade elevation even though they had stakes :beatsme . Amazingly enough the operator jumped from the writgen and lived, I'll see if I can dig up the pictures.
