Can good playground supervision prevent all injuries?
"Accidents" occur as a result of unavoidable and unpredictable situations on the playground. For example, if a child is running on the playground and trips another child this is unpredictable or typical behavior consistent with normal playground interactions. On the other hand, if a child is swinging a rope and running throughout the playground causing other children to trip over the rope this situation is both predictable and should be stopped by a playground supervisor and therefore is clearly "not an accident".
Accidents fall into two basic categories: 1. There wasn't any indication that the behavior would occur and 2. Prior intervention would not have prevented the accident. More........
