We were putting in an electrical line for the City, had the utilities marked out, all good. Apprentice cut through an 1-1/4" (32mm) gas main with the ditch witch. Suddenly saw sand puffing up; had the presence of mind to cut the engine before running. It wasn't our fault, though, because the gas utility marked it 5' (1.5m) off. It happens.
