A safety arrangement () for a motor vehicle having an electric battery () and an occupant safety device () such as an airbag () or seat-belt pre-tensioner. The arrangement () having a crash sensor () responsive to acceleration, a battery sensor (-) arranged to monitor a battery parameter indicative of the condition of the battery, an actuator () for activating the occupant safety device (), and a control unit () operable to receive and process signals (x,b) from both the crash sensor () and the battery sensor (-). The control unit () is operable to issue an actuating command to the actuator () to activate the occupant safety device () in response to a signal x from the crash sensor. In a preferred embodiment, there is provided a second actuator () for activating a battery safety device (); the control unit () being operable to issue an actuating command to the second actuator to activate the battery safety device upon receipt of both: i) a signal (x) from the crash sensor exceeding a predetermined threshold value Xand a ii) a signal b from the battery sensor satisfying a predetermined criterion.
