In the event of digging up a gas line, what is the first action you should take?

When you encounter a gas line during excavation, the first action to take is to extinguish all open flames and lights. This step is critical because gas is highly flammable and can lead to an explosion if there are any ignition sources nearby. By eliminating open flames and lights, you significantly reduce the risk of igniting the gas that may be escaping from the damaged line.

While notifying the utility company, evacuating the area, and alerting the fire department are also important actions that need to be taken promptly after ensuring safety, extinguishing open flames should always come first. The primary concern is to prevent any potential fire or explosion, which could have catastrophic consequences.
