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 when used in accordance to the manufacturer’s instructions with water suppression.  Before using this equipment you must have carried out a risk assessment and have a plan of work as required by the Control of Asbestos Regulations 2012.  You should include personal monitoring for workers to show the levels of fibres being released.

Similar equipment should not be used unless tested in controlled conditions to show that fibre release is below the STEL. Cut off Saws with water suppression release high levels of asbestos fibres when cutting AC water pipes and must never be used.
