Was looking into this and took it from the advice
here that you still need to be carefull with the cement bonded stuff
5B) Cement bonded (white) asbestos does not present a significant health risk
provided it is handled correctly, and you do not need to employ a licensed contractor
to remove and dispose of it. Cement bonded asbestos sheeting is commonly found
as grey corrugated or flat sheets, for example in garage or shed roofs. It is thin and
brittle and contains a small amount of asbestos encapsulated within cement.
Asbestos fibres are released when the cement sheeting is broken or drilled, sawn,
scrubbed or sanded.
Therefore, to reduce the risk to yourself when handling and disposing of bonded
asbestos, the sheets should be KEPT WHOLE and NOT broken, cut or sawn,

etc. If this is not possible, breaking is the preferred option - avoid the use of power
tools at all times. Dampen the asbestos first and then double bag or wrap tightly in
plastic, as this prevents further release of dust. Wear safety equipment suitable for
use with asbestos, such as a disposable masks, overalls and gloves. Protective
clothing and cleaning equipment should also be treated as asbestos waste on
completion of the task and disposed of accordingly. Never use a vacuum cleaner to
clear up asbestos waste.
