Compressed Air Work And Diving 1909

PREFACE. This book has been written with the intention of giving the main principles of compressed air work and diving rather than that it should be a historical review ; for in this respect, so far as tunnelling is con- cerned, the ground has already been to a great extent coverecl. More particularly I have been desirous of emphasis- ing the importance of the >vork of the recent Admiralty Committee on Deep Water Diving, and of Dr J. S. Haldane, F.R.S., Dr A. E. Boycott, and Lieut. G. C. C. Damant, R.N., at the Lister Institute of Preventive Medicine, which has made necessary a revision in our rules and regulations for compressed air work and diving. Accordingly, a set of rules for stage decompres- sion are given in Chapters I. and II., and as, I believe, up to the present, no similar set of rules and regulations has been given in any book on engineering, they will, I trust, be found useful. Tables I. and II. for diving, and Table IV. for caisson and tunnel work, have been very kindly placed at my disposal by Drs Haldane and Boycott and Lieut- Damant. Further information may be found in the “ Report of the Committee on Deep Water Diving,”
