MPs have condemned asbestos in schools as a national scandal after the Department for Education revealed that an estimated 75% of UK state schools contain the deadly substance.
In the past 10 years, more than 140 teachers have died from the rare asbestos related cancer mesothelioma.
The Parliamentary Group on Occupational Safety and Health's chairman, Jim Sheridan said "Urgent action is needed to prevent more pupils, teachers and other staff being exposed to this deadly killer dust.
"We need both far greater awareness of the risks that this material poses and a programme for its phased removal."
According to the Health and Safety Executive (HSE) inhaling asbestos is the single greatest cause of work related deaths in the UK, accounting for 4000 deaths per year.
A DfE spokesman said: "HSE's expert advice is based on the best current evidence.
"It is absolutely clear that if asbestos is not disturbed or damaged, then it is safer to leave it in situ, with strong systems in place to contain and monitor it."
