What About Manholes?

11/15/2010

Did you ever have one of those jobs that you absolutely hated to do? If you have ever had to deal with manholes it probably tops the list… 

Manholes, besides the uncomfortable name, create a unique circumstance, both from an electrical standpoint as well as the confined space issues they create for the worker. Often times people will try to get some relief from an internal requirement to wear Level 4 PPE, as it creates additional safety concerns. But when an arcing fault occurs in a manhole, because of the limited entry space and because the flash/blast is essentially contained within a box, it creates additional hazardous conditions.
