I work in the water utility sector and I have heard that there are some specific makes of power tools that can be used to cut large diameter asbestos cement water and sewage pipes?
The preferred method of cutting AC water pipes is by using a hand saw, especially for small diameter pipes, as this creates less dust. However, for large diameter pipes ICS Powergrit utility chainsaw, Steve Vick International Keel Cutter and MACAW pipe cracker have been tested and proven to release fibres below STEL and control limit
