Calling before you begin work ensures that underground utilities - including electrical and natural gas lines - will be marked so you can work around them safely.

Marking utilities helps prevent personal injuries that could result if contact is made with an underground line.

Workers using jackhammers or hand tools that may contact an underground line should wear protective insulated gloves.
