On 16 May 2011, a fire developed in the engine compartment of a bus.
The fire was caused by the main power cable rubbing against the engine sump causing the protective insulation to wear and allowing the wire to short circuit. This resulted in the insulation and other combustible materials in the engine compartment catching alight.
This incident highlights the importance for bus maintenance staff to ensure that when carrying out maintenance to the engine or components in the engine bay, their actions do not affect the routing or security of any wiring loom.
Bus operators should note this advice and consider it in relation to their own operations. For further information about bus safety legislative requirements in Victoria, contact Andrew Chlebica, Manager Compliance & Information on (03) 9655 6873. This advice is effective immediately.
