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.

The glove bag is constructed and installed in such a manner that it surrounds the object or area to be decontaminated and contains the asbestos fibres released during the removal process.
