a cadet has wandered off after being told once before not to do during a lesson, she wandered off again this time she tripped and cut her knee open, quite a deep bad cut almost to the bone, i went over and comforted her while sending one off to get first aid kit and the DC as there was no adults that night, first kit was brought in and first aid adminstered, her parents came in and picked her up took her home, she declined an abulance then she wanted one, th e DC at this point took over and seems she has now gone with her parents instead, one problem she has learning difficulties. an accident report has been made out. im just wondering if i have done everything right and covered myself. my views is that it was self inflicted as she walked off and tripped into some sharp stones which is in a TA centre. if you were in my position would you have done it differently ?
