Dash 8 checklist allows for the power levers to be operated together once the recalls have been completed. The condition lever is at fuel off and the fuel handle is pulled so no chance of an unexpected light-up. On the other hand the BAe146 checklist leaves the failed engine thrust lever at fuel off. I didn't have a problem with either approach. With the 146 the thrust levers are never all together so you can't forget which ones to push up from idle.
