The 6th Edition of the Commercial Diver Training Manual represents an almost total rewrite. Where previous editions were designed to be utilized in conjunction either with the NOAA Diving Manual or the U.S. Navy Diving Manual, the 6thEdition has been written as a stand-alone work that covers history, physics, physiology, diving medicine, and first aid in addition to those chapters devoted to diving technique, diving equipment, and working underwater. This manual is presented with the understanding that fully qualified instructors experienced in underwater work will provide any further explanation required by the reader. At the same time, the intent was to provide a manual to enhance both the theoretical and the practical training of the diver, with a view to providing graduates that are more knowledgeable and well informed in their chosen trade, performing their assigned tasks in a safe and productive manner. To that end, this manual strives to present the following: Diving physics in a clear, concise manner The latest theory and procedure in physiology and diving medicine The latest in practice and procedure both inland and offshore The most commonly used diving and support equipment accepted for use in today's industry While it is understood it would require several volumes to address every conceivable task performed on every type of underwater project employing commercial divers, this manual endeavors to cover the most commonly performed tasks and the most common underwater operations. By presenting these more common projects and tasks in detail, it is hoped the reader will be better informed and better prepared for a career underwater. In addition, by further illustrating both technique and safety concerns with case studies and personal accounts from the author's career, the manual shows the reader these are more than just words being presented: suggestions help the reader become more proficient and safety guidelines keep the reader from injury or death.

This new edition has been revised and expanded to cover the "how to" for the broadest possible range of underwater diving conditions and dive situations. Its primary purpose is to provide for the protection of human safety and the improvement of diver performance. It can be used as a companion piece and complement to the basic fundamentals of diving related to physics, physiology, diving medicine, first aid, marine animals, etc.

Updates in the 6th Edition - Comprehensive rewrite can be used as stand-alone reference - Extensive index - Easy-to-read formatting - Color photos/tables/figures added - Colorful book cover ABOUT THE BOOK The 6th Edition of the Commercial Diver Training Manual represents an almost total rewrite.

For several generations, the U.S. Navy Diving Manual has been considered the Bible of both military and commercial diving, regardless of where in the world these operations were performed. In the past, the U.S. Navy Diver's Handbook was the go-to source for military and commercial divers when they were in the field and did not wish to carry the complete manual with them. The last official printing of the handbook was in 1994, and after that time there was a desperate requirement for a handbook for the commercial diver. Originally published in 2013, The Commercial Diver's Handbook filled that requirement and more. It presented the three most commonly used air decompression tables world-wide, along with mixed gas tables, treatment tables, up-to-date diving medicine, a section on chamber operations, and a section on nitrox operations. Technical editing was performed by CP01 Charles Trombley, Canadian Navy. He was formerly with Canada's Experimental Diving Unit and later retired as Chief Diver, Fleet Diving Unit, Atlantic. This second edition of The Commercial Diver's Handbook has a few changes worth noting. First and foremost is the update of the U.S. Navy Diving Tables from Rev. 6 to 7. Secondly, the size of the book has increased slightly and there is larger print. The decompression tables are now in color for ease of use. As for the chamber medical kits, the handbook now specifies DMAC 15, Revision 4, and the appropriate lists are provided. In addition, the reader will notice other small changes made to keep information current in almost every section, from diving medicine through to emergency medical care. As with the previous edition, this handbook will again prove to be a valuable tool in every commercial diver and supervisor's possession, no matter where in the world they are working.

“The 7th Edition of the Commercial Diver Training Manual continues to fill the gap between learning through field experience and learning through entry-level commercial diver training. Our commercial diving students and graduates have been well served since 2016 by the author’s meticulous and thorough approach to making vast field experiences and safety come alive in the 6 th Edition, and once again in this revised 7th edition. It continues to be a leading textbook in our training, due to its technical accuracy, current content, photos, and illustrations. Safety and efficiency are pinnacle traits that any successful working diver must learn in their training and constantly apply in the field. Safety is not a simply a rule book, it is a state of mind. Hal Lomax’s approach to this and sharing his knowledge with all levels of divers has made our industry safer and advanced it entirely. At the very core of commercial diver training are two essential objectives: Going up and down in the water column safely and performing useful and effective work underwater. This textbook continues to provide both objectives into a current and well written resource for the entire industry. It remains a must for anyone’s library involved in commercial diving.” Don Barthelmess, Professor Emeritus, Santa Barbara City College Marine Diving Technology Department
