The world of education, the National Union of Teachers (NUT) said research shows about 86 percent of school buildings contain substances that can cause cancer. But about 44 percent of teachers do not know whether their school is one of a group of dangerous buildings. While 46 percent say already know the dangers of asbestos. And about 10 percent said they had been told that the building is free of asbestos.
Kevin Courtney, NUT General Secretary, said about 200-300 graduates died of mesothelioma (malignant cancer that is very rare and only affects certain people). This cancer develops in the cells of the mesothelioma caused by asbestos dust. And 22 teachers died of mesothelioma in 2012, tripled since 1980.
This type of cancer develops slowly over the age range of 30-60 years, which means the young age of a person exposed to asbestos dust, the higher the risk that arises for him.
This time not only threatening asbestos in the classrooms of schools, but the use of asbestos has been extended to the residential and office buildings. Anyone may be at risk of cancer.
