Call before you begin work around underground lines.
Before you begin any digging, blasting or excavation work, you must call 811 or your local One Call number to locate the lines.
811 is not available in some locations.
Calling before you begin work ensures 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 near underground lines should wear protective insulated gloves.
