Jump Starting

Version: 1.0

Updated: 1 December 2024

Document Summary

This Safe Work Procedure outlines the process for safely jump-starting vehicles using jumper leads, an assisting vehicle, or a slave battery/jump starter. Explosive gases released from vehicle batteries require eliminating all ignition sources, such as smoking or sparks. Only jumper leads designed for vehicle starting should be used to avoid damage and overheating.

Before starting, ensure both vehicles are stationary, parked in neutral or park, with parking brakes engaged. Cables must be connected in the correct sequence: positive (red) to positive terminals and negative (black) to a good earth point on the disabled vehicle, avoiding direct connection to its negative terminal. Engines should be started in the assisting vehicle before attempting to start the disabled vehicle. Once successful, disconnect leads in reverse order and avoid cable contact with metal parts to prevent sparks. Follow manufacturer recommendations and use jumper leads with surge protectors for vehicles with electronic ignition systems. These guidelines ensure safe and effective jump-starting.
