Scientific Diving Standards The University of Michigan Standards for Scientific Diving Operations Larry “Harris’ Taylor, Ph.D. Diving Safety Coordinator 2016 1 2 PREFACE This standard for University of Michigan Diving Operations has been prepared as a legal requirement under Act 154 of the Public Acts of 1974, as amended (Parts 3, 31, and 79), Departments of Public Health and Labor, State of Michigan. The State of Michigan Diving Operations Standard specifically states applicability "to diving and related support operations" conducted in connection with all types of work and employments. It specifically does not exclude scientific diving. The state standard was effective as of June 15, 1979. Although, the U.S. Department of Labor officially released the scientific diving community from Part 1910 of Title 29 of the Code of Federal Regulations (Subpart T), the State of Michigan has, never, to my knowledge, officially taken such action. Consequently, the University of Michigan shall make every effort to comply with the State requirements. The University of Michigan Standard also meets or exceeds the "Standards for Scientific Diving Certification and Operation of Scientific Diving Programs" of the American Academy of Underwater Sciences (AAUS) that was promulgated in May of 1984 and revised in August of 2006. Training requirements have been updated to more realistically address the population of divers and researchers served by the University of Michigan. Unlike the AAUS standard, a recreational diver scuba diver certification is listed as a prerequisite for entry into scientific diver training. Medical standards comply with the current, and more stringent University of Michigan Risk Management requirement (annual exam by a university medical practitioner) rather than the AAUS guidelines. This document is subject to periodic revision and specific items may be modified at the discretion of the Diving Safety Control Board. Employees, supervisors, and others are encouraged to notify the Diving Safety Coordinator of typographical and wording errors, unclear statements, and other items of concern. In addition, the Board welcomes suggestions for improvements to this standard. Nonotnaui1cuba divers are reminded that the standard addresses "working" diving operations rather than recreational activities and that the State, rather than the University, of Michigan, designates some requirements in this manual. The policy of the University is to comply to applicable federal and state occupational safety and environmental health standards. This standard shall be considered effective upon approval of the Diving Safety Control Board and until specific and official variance or exclusion from state standards, in part or total, are obtained and the preparation of a revised University standard.

  • Full Paper/Talk Deep Stops and Shallow Stops – Fact and Fancy
    Full Paper/Talk Deep Stops and Shallow Stops – Fact and Fancy B.R. Wienke1 and T.R. O’Leary2 1 C&C Dive Team Ldr, Program Manager Computational Physics, LANL, MS D490, Los Alamos, NM 87545 [email protected] 2 Director, NAUI Technical Diving Operations, 33256 State Rd 100, South Padre Island, TX, 78597 Abstract The question of deep stops and shallow stops is interesting and fraught with controversy in diving circles and operations, training, exploration and scientific endeavors. Plus frought with some misunderstanding which is understandable as the issues are complex. We therefore attempt a short history of deep and shallow stops, physical aspects, staging differences, diving tests, models with data correlations and data banks with user statistics and DCS outcomes as diver amplification. Pros and cons of both deep stop and shallow stop staging are presented. Misfacts are righted when appropriate. Chamber, wet and Doppler tests are contrasted. A compendium of Training Agency Standards regarding deep and shallow stops is included. Dive software is also detailed. Some commercial diving operations are discussed. A short tabulation of dive computer and software algorithms is given. From diving data, tests, DCS outcomes and field usage, we conclude that both deep stops and shallow stops are safely employed in recreational and technical diving. That is a good thing but choose your deco wisely and know why. Keywords: computational models, decompression staging, profile data, risk, statistical correlations, tests Acronyms and Nomenclature ANDI: Association of Nitrox Diving Instructors. BM: bubble phase model dividing the body into tissue compartments with halftimes that are coupled to inert gas diffusion across bubble film surfaces of exponential size distribution constrained in cumulative growth by a volume limit point.

  • Deadly Acute Decompression Sickness in Risso's Dolphins
    www.nature.com/scientificreports OPEN Deadly acute Decompression Sickness in Risso’s dolphins A. Fernández, E. Sierra, J. Díaz-Delgado, S. Sacchini , Y. Sánchez-Paz, C. Suárez-Santana, M. Arregui, M. Arbelo & Y. Bernaldo de Quirós Received: 19 April 2017 Diving air-breathing vertebrates have long been considered protected against decompression sickness Accepted: 5 October 2017 (DCS) through anatomical, physiological, and behavioural adaptations. However, an acute systemic gas Published: xx xx xxxx and fat embolic syndrome similar to DCS in human divers was described in beaked whales that stranded in temporal and spatial association with military exercises involving high-powered sonar. More recently, DCS has been diagnosed in bycaught sea turtles. Both cases were linked to human activities. Two Risso’s dolphin (Grampus griseus) out of 493 necropsied cetaceans stranded in the Canary Islands in a 16-year period (2000–2015), had a severe acute decompression sickness supported by pathological fndings and gas analysis. Deadly systemic, infammatory, infectious, or neoplastic diseases, ship collision, military sonar, fsheries interaction or other type of lethal inducing associated trauma were ruled out. Struggling with a squid during hunting is discussed as the most likely cause of DCS. Pathologies related to efects of changes in pressure are well known among human divers. Decompression sick- ness (DCS) is a syndrome related to the formation of gas bubbles in blood and/or tissues when the sum of the dissolved gas tensions exceeds the local absolute pressure. Gas bubbles may have biochemical efects and disrupt the tissues or occlude the vessels with clinical and pathological signs and, in certain cases, death1.

  • Bill's Cave Diving Lexicon
    Bill’s Cave Diving Lexicon 120 Rule: Noticing from the Navy NDL table that, for certain depths, depth + bottom time = 120 so that the NDL can be determined by subtracting the depth from 120. 200 DIN: Thread depth in a DIN valve and associated pressure (200 BAR) that can be handled. This size (7 threads) allows for a DIN to yoke conversion. 300 DIN: Thread depth in a DIN valve that provides the most secure (9 threads) connection and can withstand 300 BAR pressure. 5 nines pure: 99.999% pure, as in a gas. 50-50: Gas mix of 50% oxygen and 50% nitrogen used for decompression gas. 6351-T6 Aluminum Alloy: Alloy that has had problems with tank ruptures. Absolute Pressure: Total pressure being exerted on a diver At sea level Absolute pressure is 1 ATA and it increases by 1 ATA for each 33fsw (34ffw). ADDD (Air, Duration, Depth, Distance): Limits for dive termination acronym minimum Air volume/pressure, maximum Duration of dive, maximum Depth of dive, and maximum Distance of penetration. ADV (Automatic Deflation Valve, and Automatic Diluent Valve ): Device on a buoyancy compensator that allows for rapid air purging, and device on a rebreather that dilutes the breathing mix. AGE (Arterial Gas Embolism): A lung expansion injury. A condition in which gas bubbles enter the arterial system and cause damage by blocking blood flow to vital organs, most commonly the brain. This is generally caused by air passing through the walls of the alveoli into the bloodstream. Air: A gas mixture of Oxygen (21%), Nitrogen (78%), and other gasses (1%, Helium, Argon, etc.).
