“Right first time in Time”
Volvo’s commitment to safety includes taking into consideration the safety and preparedness of our
technicians, to properly service our vehicles.
Prior to the start of any high voltage battery work being performed, a risk assessment / safety check shall
be performed. This is also known as a “Permit to Work Live Voltage”.
The Permit to Work Live Voltage document serves as an overarching communication that fully
encompasses any and all electric vehicle (EV) battery repairs such as hybrids and battery electric
vehicles. This document is not intended to replace or supersede any national, state, or local safety codes
or regulations.
This Permit to Work Live Voltage document shall be filled out by the Advanced EV technician each time
live voltage work is performed. This, for example, can include battery disconnect unit replacements, and
internal high voltage battery repairs that require the lid to be removed. It also includes times when the
repair takes more than one day to complete, and the technician returns to the vehicle on subsequent days.
Volvo recommends the retailer retain a copy of this completed document for a period of (7) years or as
required by National, State and Local ordinances, whichever is greater.
*Retention of the Permit to Work Live Voltge document is required for Warranty and Technical auditing
purposes.
Failure to produce the Permit to Work document, when requested, could result in a debit to a claim.

Produced and printed in the USA and available as an electronic document.
