Use of rubber insulating gloves and sleeves while performing distribution powerline tasks via the live line tool method.
A. When working primary voltages aloft:
For the purpose of this document M.A.D. is defined as the Minimum Approach Distance defined by applicable Federal, State or Local regulation. M.A.D. may also be known as "Primary Contact Zone", "Minimum Working Distance, "Within Reach", "Extended Reach", etc.
This Best Practice only applies to those applications where power-line workers are utilizing the "live line tool work method" aka – "hot sticking." Workers using the "live line tool work method" ("hot sticking") use insulating tools designed and intended for use while working on energized equipment and/or conductors. Workers using the "live line tool work method" are not permitted to make direct contact with energized equipment and/or conductors with their hands and are not permitted to be in a position where the worker can reach into, extend any conductive object into, or extend any other part of the body into the M.A.D. as prescribed in applicable Federal, State and Local Regulatory Standards.
It is not intended nor required that the Strategic Partnership Cradle-to-Cradle Rubber Glove Work Method Best Practice be applicable when power-line workers are using the "live line tool work method". The Cradle-to-Cradle Rubber Glove Work Method Best Practice applies only when work is to be done utilizing the "rubber glove work method". When a task requires the worker to reach into, extend any conductive object into, or extend any other part of the body into M.A.D. while using the "live line tool work method," the use of rubber insulating gloves and/or rubber insulating gloves and sleeves rated the voltage are required to be used as described in this Best Practice".
Donning of such PPE shall be done in a safe location so that M.A.D. requirements are not violated. This may include repositioning of the aerial lift to its cradled position. It should be noted however, incident investigations have revealed M.A.D. violations have occurred during "live line tool work method" operations. The intent of this Best Practice is to eliminate both M.A.D. encroachment violations and subsequent injuries.
