HSL investigation refutes asbestos claims over safe cement
The Health and Safety Laboratory (HSL) have investigated claims that chrysotile in asbestos cement changes into a non-asbestos fibrous material called Casitile. The claims also suggested that this process is 100% efficient and no chrysotile asbestos remains in the matrix and no release of airborne chrysotile fibres can occur.

Asbestos is the largest cause of work related deaths in the UK and was widely used particularly during the 1950’s to mid 1970’s.
Asbestos and ACM's have undergone a gradual, both voluntary and formal, banishment from 1970 - 2000. Any buildings built after this date are highly unlikely to contain asbestos.
For asbestos to become harmful to individuals the fibres have to be inhaled and penetrate the lungs. The most common way for this to happen is when asbestos is disturbed and the fibres are released, which can happen during demolition works or when carrying out maintenance work on buildings.
