VANCOUVER, British Columbia (AP) _ A rotating platform that carries audiences between two theaters in Expo 86's Canada pavilion will reopen this week for the first time since a 9-year- old girl was killed by the device.

Karen Ford of Nanaimo was crushed as the turntable rotated between the Earthwatch and Canada Celebration theaters. Audiences have been walking between the two shows since the May 9 accident. Expo officials haven't said exactly what day it will reopen.

The theatre has had ''some design modifications,'' and staff are being trained in new safety procedures, said pavilion spokesman Jim Patterson.

He would not say what will be different when the turntable begins operation again, although he did say the turntable itself hasn't been modified.

Coroner Diane Messier is holding her own inquiry into Miss Ford's death.
