The Diving Management Study CCO Ltd. No. 8, "Set a policy for electronic devices in chambers" is based on reports from QinetiQ, a multinational defense technology company headquartered in Farnborough, United Kingdom, and from the aviation industry, which deals with the problems posed by these devices on a daily basis and has developed efficient methods for managing them. Therefore, rather than strictly

The study CCO Ltd. No. 10 "Working at Height during the Mobilization and Maintenance of Diving and ROV Systems" is based on incident reports from diving client representatives and guidelines from the European and similar international standards, which are faithfully reproduced. The aim of this document is to provide methods to reduce the risks associated with these activities, which are too often neglected by divers.

prohibiting the use of electronic devices, including cell phones, in the chambers, this document proposes methods and tools to manage them efficiently so that divers are not deprived of their use while at the same time implementing strict control measures to ensure that these devices do not cause additional harm.

Several papers are currently being written that require the review of numerous documents and consultations with scientists working on the topics discussed, who have their own schedules, extending the writing process beyond the initially anticipated timeframe. In addition, these papers are based on some scientific articles that have not yet been published. Consequently, their publication depends on the publication of these reference papers. Also note that many new documents have been added to the website database, and it is planned to include them in the written manuals later this year. In the meantime, the two "Diving Management Studies CCO Ltd." below and others provide documented and innovative guidance on the topics they discuss and should be read.
