  6. Diver who died near Fox Island was Olympia man BY STACIA GLENN sglenn@thenewstribune.com A commercial diver who died Tuesday near Fox Island has been identified as Daniel Hall, 36, of Olympia. Hall apparently ran into trouble shortly before 2 p.m. just south of the Navy Surface Warfare Center area. Witnesses called 911 and pulled Hall aboard a commercial geoduck boat 100 yards from shore. They attempted CPR on the unresponsive diver and met paramedics at the Navy dock. Hall was taken to St. Joseph Medical Center in Tacoma, where he was pronounced dead. He worked on the commercial boat for the Squaxin Island Tribe, Pierce County sheriff’s spokesman Ed Troyer said. The Coast Guard will investigate what caused his death.

  7. I will be receiving the Printed Copies for Review on the 17th or 18th this month. Most divers will never have the chance to be taught to burn properly, they will learn in the field as most of us have. Hopeful the way I've put this manual together, they can buy it and learn how not to kill themselves, even when surrounded by a team that knows less than they do. The smart ones will note that my e-mail address is in this course, the smart ones will ask what they don't understand. The attached pictures are ones I created to help make the point about: Why the Drag method: IF YOU'RE IN FRONT OF THE CUT WHEN AN EXPLOSION HAPPENS; Oxy-Arc Burning can be done safely!

  11. Hi Derek - fascinating (And NO, I did not follow the maths!). Basically used records of over 3,000 actual dives and applied a three state model to predict no DCI, mild DCI (Pain only) and Serious DCI (Cardio/neurological DCI) They used the 2008 (Rev 6) USN tables 'no decompression limit' to compare the US Navy's 'standard' of accepting up to a 2% risk of mild DCI and 0.1 % risk of serious DCI (I'm not sure many commercial diving people will accept a hit rate of 'one serious DCI per 1000 dives as normal) They concluded that the USN 2008 'no decompression limits' was conservative for mild DCI - ie you could - theoretically!!! - dive longer for the before you reach the 2% risk of mild DCS BUT they also noted that you had to 'vastly reduce' bottom times to keep within the 0.1 % risk of serious DCS To meet the 0.1% risk of serious DCI, the table they quoted was the French Navy NM90 table. Which kind of supports a lot of people's gut feeling that the old USN air tables are a tadge risky when used straight out of the box - even the US Navy concluded they produced an unacceptably high rate of DCS in the deep air range - That's why they upgraded from Rev 6 to Rev 7 last yea (And why they upped from Rev 5 to Rev 6 in 2008). I believe - but am open to being corrected! - that the French Navy tables are based on a Haldanian model (derived from extrapolating data from actual dives) as opposed to Algorythms (bubble modelling maths) which kind of pushes one to think that science is good, but actual experience is better. It would be interesting if they re-ran the modelling using the NDL limits from USN Rev 7 to see if the new version is any safer. Thanks for posting the link!
  12. I'm going to read it and then comment
  13. John, i don't understand this article. You can't predict where a bubble will end up and how painful it will be. Each dive and diver are different. Hence a neurological exam.

  15. This technology will never prove it, we will see what the divers who use it say
  16. We've been monitoring the progress of this system for a while now and asking lots of questions of the developers - it seems as though it works well in tanin-stained waters, when it comes to water that is dirty with particles it improves visibility in limited viz., but doesn't help when the particles are really thick and you can't see bugger all - even the IR light can't penetrate the particle soup then.
  17. Tony, Please keep us updated of any developments. I know it has to have been a hell of a struggle for you.
  18. My most recent BOSIET update was with FALK located in Dartmouth, Nova Scotia. They also have an excellent course there

  21. Thanks very much for posting this update Mark. We are very confident of safety improvement within this industry as a result of the inquest, and if not then we will continue to campaign. I am sure some employers do not appreciate the value of a life let alone an individuals right to a safe workplace.
  22. Taken from this post: Hello Hal, below a translation from the newspaper El Siglo: Elmer Quintero CedeñoElmer.quintero@elsiglo.comSources said that divers were trapped and sucked by the currentTRAGEDYTwo divers died after being sucked by a sewer at a time when they were cleaning a canal at the Gualaca Hydroelectric Power Plant of Celsia Centroamérica, S.A., in Gualaca, Chiriquí.The facts were recorded at approximately 12:40 pm yesterday afternoon.Citizens Roderick Araúz, 35, and Jose Garcia, 43, were hired by the hydroelectric company to carry out work as divers and clean the canal that reorients the waters of the River Estí and, while carrying out these tasks, were dragged by the Current through a sewer that I push them to another channel.Ambulances of the firemen of Gualaca and other security institutions were transferred to the place, and the staff performed cardiopulmonary resuscitation (CPR) maneuvers, but the effort was in vain.In the same way police units were presented, of the Sinaproc, Firemen, DIJ, Criminalistics and the Municipality of Gualaca.The Personería carried out the lifting of the corpses of these two people.Roderick Araúz was captain of the Volunteer Fire Department at Gualaca Station and worked as a firefighter at Enrique Malek Airport in David.According to a statement from the company Celsia Centroamérica, the two divers were hired by the contractor Interpa Holding Corporation, S.A, which was routinely called to carry out works on the canals.It was indicated that, as soon as the accident was known, the emergency plan was activated and representatives of Celsia Central America contacted the corresponding authorities to provide immediate attention."At the moment the company is providing the necessary support both to the relatives of the deceased and to the authorities, in order to clarify the facts and determine the causes of this unfortunate accident," the company said in a statement. End of translation from El Siglo Newspaper. Facts that I obtained: The divers were Scuba Divers, the "Contractor" company was owned by one of the divers. They were using scuba at the moment of the incident. One of the reasons this things happen here is because there is no law for dive operations. A group of professionals presented a law that will be discussed by senators in January 2017 (we been trying for years but politicians always find the way to block it). Will keep you updated on any advance regarding the dive law. Gabriel
  23. There is an article about the high rate of deaths in Spain here: http://www.elconfidencial.com/espana/2017-03-02/buzos-profesionales-precariedad_1340942/?utm_source=facebook&utm_medium=social&utm_campaign=BotoneraWeb It needs google translate unless you are a Spanish speaker, but seems to how that Agustin Ortega died of a heart attack. I may be getting cynical, but that seems to be used as a reason for divers dying rather a lot.
  24. Once it has been developed to the point of being surface monitored, I can see the oil companies requiring this technology for all asset inspections in zero visibility. The sales people ought to be marketing this to Chevron, Shell, Exxon-Mobil, BP, Total, Aramco and the rest of the lot just as soon as they can get the imagery onto a surface monitor. This looks like breakthrough technology to me.
  25. Everyone I showed immediately saw the value. The times (no vis.) you have had to argue with your customer because it is not like what the job plan or the As Built Prints say. The times (No Vis.) your fingers are telling you one thing and your head another. The times (no vis) you have a tie-in assembly and every valve has to be in the right position. You get the point! They are about 6 to 8 mouths being ready for anything but Scuba as their major market is Search & Rescue. Mainly done in scuba by Police and Fire Departments across the nation. Any Commercial Diving Company that works in Black Water and does not have this capability when offered to us: It's my guess, you snooze you lose, your competitor will. They way the Hammer Head is set up right now, just the diver sees and it's not recorded. They will be offering topside viewing and recording through the divers umbilical in the near future. I believe that every Diver Supervisor and Inspection Coordinator will want this on their job. Even divers will be happy to ware it when it applies. They have used it for topside Welding & Burning and it works but so far they have not tested it in black water. They will be doing that soon. Anyone interested, can get on VP of Sales Christina Baker's E-mail list, I am! christina@darkwatervision.com Their Web Page
  26. The Working Group Members: A member of the Board of Directors ADCI, a Diving Representative of IMCA, a Representative of The United Brotherhood of Carpenters and Joiners of America, a Diving Company owner and a Dive School Owner, One Representative each from these Equipment Manufacturers: Oxylance Corporation, Broco Rankin Industries and Fire Wire Marine. We are shooting for a Recognized Underwater Oxy-Arc Burning Standard under the American Welding Society, AWS. Everyone has agreed it is well past due. Step 1) Up Grade: Ocean Technologies Oxy-Arc Underwater Burning Course. Completed. Step 2) Revise Burning Training for new Students at: Commercial Diving Technologies Safety Training will be exactly the same for new students as it will be for the Stand Alone Advanced Course. It will include set up and checking out equipment. A minimum score, of 80% to pass before further training in Oxy-Arc. They will have Basic familiarization with one type of exothermic rod on ½ plate. Their diploma from the school will reflect they passed the Oxy-Arc Burning Safety Training and completed basic familiarization with the rod used. Re-write Completed Step 3) Submit Revised Ocean Technologies Oxy-Arc Underwater Burning Course for all parties involved (See working Group). Completed. Step 4) Run new Safety Course for Students at: Commercial Diving Technologies.To Be Anounced Step 5) Run Stand Alone: Oxy-Arc Underwater Burning Training Course for Divers To Be Anounced Divers must have completed an Accredited Commercial Diving School Have a minimum of 30 Logged Commercial Dives. To begin the practical part of training with Exothermic, Tubular Steel and Swordfish Arc Cutting Electrode, You must have passed the Safety Training portion with a minimum of 80%, reviewed any incorrect answers and understand the correct answer. If we are successful in moving this forward toward a American Welding Society approved standard Commercial Diving Technologies & JCRoat Subject Matter Experts Services will run an Instructors Qualification Course. We will provide the written course, Instructors Notes and Videos that go with that course, to the Graduate Instructor/s. Interested parties can contact Sid Preskitt, Commercial Diving Technologies at 321-212-8550 or underseas6@yahoo.com for more information, Attention All Members of the Divers Association International: As this is a Board Member, John Roat's, effort at creating an Oxy-Arc Underwater Burning Certification the Association will post an internal poll of its members on the subject before voting to support this effort!
  27. Derek and All; The current problem is not over use of burning as it was in the old days. The problem currently is, it is only used, when some other method fails. Even when Burning would have been a safer way, such as: Setting the saw when with vessel movement is bouncing the saw around. The worst problem is, due to the OGPI 471 suggestions and them not quailing a course or any Instructors, for that course, there is no burner training/Cert. Yet it is on every job as back up or and emergency, such as trapped bell. The last place I want a diver with little or no experience with a cutting torch. I agree on cost being stuffed up the divers behind but if training is available, the Oil Company needing the service, will pay. Plus with this class: Just the Safety Portion that will be taught to divers going through dive school.." So my question would be which certification body would write up and approve the training establishments for such training" The ADCI has begun a review of the Course. and has said they will put the ADCI Stamp on the Course if it meets or exceeds their requirements and has qualified Instructors, it does. IMCA does not do that but I was told if it meets or exceeds IMCA D003 Guidelines for Oxy-Arc Cutting. we can state that on the course, it does. Both IMCA and The United Brotherhood of Carpenters and Joiners of America, the National for our Divers Union, want a specified re-qualification/testing period. After the first: Stand Alone: Oxy-Arc Underwater Burning Training Course for Divers, I will run Instructors Qualification Courses. We will provide the written course, Instructors Notes and Videos that go with that course, to the Graduate Instructor/s. We are working on recording keeping. which will be done digitally. Written testing and Practical testing see attached, for this one both Instructor, Student and his cuts will be in the picture. It will take off fast, unless the Oil Companies need it some where, such the last time we had big hurricanes in the GOM. PS there will even be a power point to educate safety issues for customers that are educated to safe burning practices or Planers.
