DIG WITH CAUTION
• Accidental severing of underground cables or gas
lines may cause an explosion and/or fire, possibly
resulting in serious injury or death.
- Before digging, check the location of cables, gas
lines, and water lines.
- Keep the minimum distance required by law from
cables, gas lines, and water lines. If a fiber optic
cable should be accidentally severed, do not look
into the end. Doing so may result in serious eye
injury.

companies directly (electric power, gas, telephone,
water, sewers, telecommunications, etc.) to obtain
information about underground utility lines.
