Linemen with Commonwealth Edison (ComEd; Chicago, Illinois) once relied solely on visual inspections to evaluate problems inside manholes. Now if field crews are aware of an unsafe condition, they have the option to send a camera down first inside the manhole rather than an employee. Field crews recently were introduced to the Utility Inspection Video System by Zistos Corp. (Holbrook, New York) to get a visual picture of a manhole.
