Be aware that serious accidents and even fatalities can result when excavators, contractors, and others do not use proper care to avoid contact with underground and above ground electrical facilities.
In a continuing effort to reduce needless injuries, power outages, and damages, our Damage Prevention Specialists aggressively investigate contacts causing damage to electrical facilities. Taking immediate action after accidental contact is made, these specialists meet with the management of companies to explain the consequences of continued unsafe and neglectful practices. They enforce aggressive policies involving collection for damages and initiate legal intervention to stop companies that have established patterns of irresponsible work practices.
The team sponsors Damage Prevention Councils and works closely with DIGGER and J.U.L.I.E. to promote safety and damage prevention. Contact a ComEd Damage Prevention Specialist at 1-630-691-4759 or email
