| 摘要： | Buses have an arduous lifecycle with short stop-and-start journeys, variations in loading and are often subjected to traffic congestion. While buses have a rigorous maintenance programme taking into account their use, there is still the possibility that some components may fail prematurely, which could lead to breakdown or even result in a vehicle fire.DVSA has reviewed 242 reports on bus fires and thermal incidents received since January 2020. These included incident reports or safety concerns raised with its vehicle safety branch. It summarised the reported causes to the fires (see pie chart) and assessed fire reporting procedures, maintenance requirements of vehicles and manufacturers' schedules, concerns of engine bay temperatures (see box), driver training and awareness, and the consequences of bus fires.The study confirmed that repair practices are partly to blame for causing fires. Some reports identified incorrect repair procedures, such as heat shields left off, or repairs that have not taken into account the effect of the fault on other components. Often when a fault is fixed - for example, overheating - there was no consideration given to what else it may have affected. In addition to fixing the fault, DVSA recommends that technicians consider the degradation that the overheating may have caused. Often such damage is irreversible, and this can lead to premature failures or even fires, it said. |
