SAFETY guidelines for physical education lessons are adequate, an inquiry into the death of an eight-year-old girl during a ball game has ruled. Kwok Mui-yee, a primary three student at St Mary's Canossian School, collapsed last month. She had a history of heart problems. The school yesterday said it would re-issue forms asking parents about their children's health and whether they were fit to attend physical education lessons. Mui-yee's parents did not inform the school of her heart problem. They did not object to her attending the lessons. The Education Department concluded in the inquiry that the school had adopted appropriate measures after the accident and the exercise guidelines were sufficient. Exercise teachers are only required to have basic first-aid knowledge but each school needs two teachers with first-aid qualifications. But Mary Nissen, a registered nurse, said all teachers should have basic knowledge of resuscitation. But Principal Inspector (Physical Education), David Kan Wing-kay, said a physical education teacher had performed basic first aid on the girl.
