Usic had made contact with several workers on site while completing the locate and had cleared the dig tickets as excavation site clear. These two workers, plus a third worker, were said to have been digging with shovels around a caisson close to the damaged gas main. Multiple taylor excavating employees stated that they had not smelled gas at any time prior to the ignition. Taylor excavating stated they had 3 employees digging with shovels around the caisson which is near the gas main when the fire erupted. The owner and foreman on site stated that there were several metal shavings in their excavation and maybe they hit one of those or the caisson and caused a spark. They stated that they were digging around the caisson and moving the earth towards a trencher that was removing the spoil. The trencher was said to have been approximately 15 feet south and 5 feet west of the damaged gas main.
