Callistemon, if your above post is addressed to me, I do not view school children as "raw materials".
I view those children in the same light as adults who work in factories, distribution centres, or even sewage treatment plants. They are all individual persons, who when involved in school or any workplace accident or incident will become injured, maimed, sick or even killed as we so often deal with in the course of our work.
The above we always try to prevent rather than having to investigate after an incident had taken place.
As I have stated in this thread, we do not normally undertake public safety work such as in schools, so I would not be aware of any statistics on School accidents or infections. However, we were/are prepared to undertake the requested assistance at the Academy School mentioned if we can get cooperation on assessing to the premises.
