Locate the main electric fuse or circuit breaker box, water service shut-off, and natural gas or propane main shut-off, and mark them clearly. If you don't know how to turn them off, contact your utility companies to learn how to do so safely. Teach family members when and how to turn the utilities off. Keep the area around shut-off switches clear of clutter for easy access. If you need a special tool, hang it up right next to the shut-off.
