LEARNING POINTS / ACTIONS TAKEN
Undertake minimal repair work at the roadside or third-party premises. The best place to undertake such work is at an adequately equipped vehicle repair facility.
Prevent movement of air suspension, either by deflating the system or by using suitably rated props or stands to prevent the chassis lowering. Under no circumstances should air suspension be relied upon to maintain a vehicle’s ride height or position whilst people gain access to areas where they may become trapped.
Exhaust the air from the air suspension system before working on it.
Isolate the air suspension system by physical disconnection of the air supply before working on it. You should not use clamping of air suspension pipework as a means of temporary isolation as it is not secure.
