Competencies And Responsibilities

Introduction

NOTE: Please refer to the workshop literature to determine who is authorised to work on high-voltage vehicles and which tasks they are allowed to perform.

The introduction of hybrid technology at Porsche requires a re-evaluation of the qualification degree of the workshop personnel. Due to the varying nature of the work performed on hybrid-specific and conventional components in our vehicles, it makes sense to structure the qualification into different levels. Electrically instructed persons (Eip) or high-voltage technicians (HVT) employed in the workshop will share responsibility for the maintenance and repair of hybrid vehicles in the future.

High-voltage technician (HVT)

The high-voltage technician has the ability to check the function of all high-voltage components installed in the vehicle. If necessary, the technician can disconnect the high-voltage system and then check that there is no electric charge. If a vehicle cannot be de-energized, the technician can request the assistance of an electrically skilled person (Esp) to assume responsibility for completing the task. To do this, he must create a PTEC.

The technician is allowed to assign work on vehicles disconnected from the power that is defined in the workshop literature to electrically instructed persons, but must assume responsibility for the correct completion of the work. When the work is finished, the high-voltage technician is the only person permitted to start the hybrid vehicle again.

Electrically instructed person (Eip)

Electrically instructed persons are instructed of the dangers of handling hybrid components improperly. Under the instruction and supervision of the high-voltage technician, they perform defined tasks on the voltage-free system as well as tasks that do not require the disconnection of the high-voltage system.

Electrically skilled person (Esp)

Electrically skilled persons possess extensive knowledge of the dangers of electrical current as well as the hybrid technology used in Porsche vehicles. He has the ability to disconnect the high-voltage system using different methods to those described in the Workshop Data (e.g. on accident vehicles) and is therefore allowed to perform work on live high-voltage systems. The manufacturer provides him with assistance if necessary. The HVT submits a request for assistance from an electrically skilled person by issuing a PTEC.

Employees not qualified for high-voltage work

Employees who do not have any of the qualifications mentioned above are not qualified to perform work on the high-voltage system. This applies to all remaining staff at the Porsche dealership. They are not allowed to work on hybrid vehicles and are instructed on how to deal with hybrid vehicles in the Porsche dealership as part of an internal company health and safety briefing held at least once a year.

Company operator/Superior

The first and foremost duty of the company operator is to prevent accidents in accordance with the relevant applicable guidelines on occupational safety.

The operator assumes responsibility for guaranteeing the qualification and motivation of his employees. He can nominate and appoint in writing technically skilled employees to perform certain duties. A successfully qualified high-voltage technician needs to be nominated and officially appointed in order to perform work on vehicles with high-voltage systems. The appointed high-voltage technician does not receive any technical instructions from his superior, i.e. he makes professional decisions independently. The company operator must implement appropriate procedures for selecting suitable employees:
- Duties must only be assigned to employees who possess the relevant qualifications.
The company operator is obliged to ensure that advanced training measures for obtaining the qualifications mentioned above are implemented and supervised accordingly.
- It is essential that only employees that have received adequate instruction are granted access to dangerous areas.
