We, as divers, are exposed to multiple risks. Some of these are due to the divers actions. Others originate from the challenging underwater environment. This book provides clear information on how to manage diving- related risks. We will see that overlearning basic skills mitigates the impact of stress, and we will learn correct team-management procedures. Analytical tools like Fault Tree Analysis will be used to identify the root causes of diving incidents. Finally, we will understand how to develop safe and proficient diving plans. An extensive and detailed bibliography supports the material. The book will be of interest not only to the more advanced divers, technical divers, and professional divers but also to divers at the beginning of their career because starting with a good plan is the key to successfully achieving great results.
