Personally, I feel that there was no negligence in the Steinbach article. Even though there was harm (and in some cases death) caused, an athlete assumes the risk of all sporth and activities that they participate in. The school or other entity didn’t cause the injury or death. These are just instances of freak accidents (again, just my opinion)
In order to prevent more of these from occuring there are a few things that could be done. First, more supervision could be provided to help warn participants when disks or javelins etc. are airborne. Secondly, there should be more protective materials around pole vaulting areas, and other places in which people could be airborne. Finally, and perhaps most important, the pedestrian patterns (in terms of whrere and when athletes go and retrieve their materials) should be re-examined. Threre is no reason why, a person should be in a position where they could be hit or impaled by a flying disk or javelin.
