I think there is a place for Health and Safety and the teaching of issues relating to Health and Safety for children and young people. I also think we go far to overboard on some very basic safety issues that should really just be regarded as common sense (eg: taking children into your school grounds).
Anyway, I thought that the range of products from Road Masters UK Ltd were a good start on how issues regarding Health and Safety should be taught in schools for a very early age. Learning through purposeful play, fantasy and dressing up at its very best (I wonder if they make their Garden Centre Facia in my size?).
