Hi all,
First time poster. I have a situation where I have contractors entering a manhole to pull cable. The manhole is equipped 7.2 kev lines, the conductors are not exposed. They plan to enter the manhole using ARC Flash PPE to lay down insultated blankets over the cables. After that they plan to work without ARC flash PPE. Does the following statement from NFPA 70E preclude the use of ARC Flash PPE Protection? Any help greatly appreciated.
(F) Confined or Enclosed Work Spaces. When an employee
works in a confined or enclosed space (such as a
manhole or vault) that contains exposed energized electrical conductors or circuit parts operating at 50 volts or more or where an electrical hazard exists, the employer shall provide, and the employee shall use, protective shields, protective barriers, or insulating materials as necessary to avoid inadvertent contact with these parts and the effects of the electrical hazards. Doors, hinged panels, and the like shall
be secured to prevent their swinging into an employee and
causing the employee to contact exposed energized electrical conductors or circuit parts rating at 50 volts or more or where an electrical hazard exists.
