Gauging DOT 3AL3000 SCUBA cylinder neck threads
In response to requests for clarification, from members in the Far East and Australasia, the following guidance is issued for SCUBA cylinders and valves that utilise the ¾" NPSM thread form.
ASSET recommends that technicians, involved in the assembly and maintenance of SCUBA cylinders and their valves, use the appropriate, calibrated, thread gauges as a means to ensure that they are both within tolerances and compatible with each other. Additionally, the technician should have received training in their use, as provided in the ASSET Dive Industry Technician’s and Cylinder Tester’s Courses and Manuals.
How to Avoid Isobaric Counter diffusion hits during trimix decompression
Isobaric Counter Diffusion triggered by breathing gas changes is predominantly a problem when carrying out Trimix dives that are deep enough and long enough to generate formal decompression stops that require the use of a hypoxic Trimix. An analysis program embodying these concepts to identify known unsafe ICD gas switching practices and unsafe decompression is made availableDecompression trends for extreme dive planning
Deriving the underlying laws and predictive mathematics for diving physiology, safe decompression, Oxygen toxicity tolerance, narcosis, and HPNS (High Pressure Nervous Syndrome) have challenged the minds of the worlds brightest scientists. That many of the victims of incorrect decompression fail to survive extreme decompression and be part of the observable phenomenon database further hampers progress. As a first topic in this series of articles we will take a more in depth look at decompression and how to survice it's more extreme effects.Vigilance urged when treating decompression illness with US Navy table 6A
Satahip, Thailand 2005 was the location for the first hyperbaric technician course run by the British Diving and Diseases Research Centre (DDRC) - An organization set up to study the effects of pressure and provides hyperbaric chamber oxygen treatment facilities and medical training for divers, technicians, nurses and doctors worldwide. During the course, the use of the various USN tables for the treatment of decompression illness and was studied. Technician trainees also had the opportunity to visit monoplace chambers at the Queen Sirikit Naval hospital to witness the use of hyperbaric oxygen to treat skin infections that did not respond well to other techniques. For divers, the treatment of DCI generally results in the use of two US tables. Table-6 for type I DCI-pain only symptoms and skin rashes, and USN treatment table 6A for the treatment of type II DCI-Arterial Gas Embolism. Unfortunately, table 6A is also notorious amongst for causing DCI amongst attending medical personnelWorld record deep dives made using new decompression technique
A new decompression diving technique based on the Combined Decompression Model CDM-18 that provides the knowledge base used by two previous world record breaking deep divers is made available to the diving public. A spreadsheet implementation of the CDM-18 model analyzes any dive profile and breathing gas combination for correct decompression methodology, clearly identifying any profile abnormality or breathing gas change that would likely cause DCSFirst Internationally recognised Dive Technician Courses to be run in Thailand
