Identification

Asbestos fibres cannot be isolated and identified by the naked eye (a single Asbestos fibre is the size of a hair on the leg of a housefly!).

As many building products had Asbestos gradually phased out of their contents (i.e fibro sheeting), sampling is suggested for 100% identification of a suspect Asbestos Containing product. Townsville Asbestos Pty Ltd use a NATA approved laboratory for all sample testing, and can provide a written report for your peace of mind.
