Similar troubles occur with drain lines. If we were able to use PVC piping and fittings the number of joints would be considerably reduced and minimise this hazard. It would be appreciated if you would give this consideration and let us have your comments. Yours faithfully, AUSTRALIAN BLUE ASBESTOS PTY LTD Handwriting (Initialled by) 6 For General Superintendent
