Commercial Diving Physical Examination
Commercial Diving Physical Examination To the Applicant / Student: Attached are the forms and instructions for a commercial diving physical examination. One of the most important requirements for acceptance as a student in the Professional Certificate in Marine Technology at National University and to become a commercial diver is a thorough physical examination in accordance with Association of Diving Contractors International standards. As a commercial diver, it is a personal responsibility to always have a current physical exam. A current physical exam must have been completed within the last year and there must be no physical maladies which would preclude you from diving or making hyperbaric exposures. Although the commercial diving physical examination can be done by any licensed physician; it is always best to have the physical examination done by a physician who is trained in diving medicine or hyperbaric medicine. Attached is a list of physicians in Los Angeles and San Diego who are approved to conduct diving examinations. You must have the physical examination completed including the laboratory testing (which can take several weeks) prior to the beginning of the program. The cost of the examination can vary and supporting laboratory fees can range from $275 to $600 dollars or more depending on if the physician finds the need to run additional tests. You are personally required to provide the following forms completed and signed by the doctor: The attached National University Polytechnic Institute letter stating that you have passed the physical examination and are cleared for work as a diver and for hyperbaric exposures. The attached ADCI form (Medical History and Physical Examination) completed and signed by yourself and the physician. -

TDI Advanced Nitrox Diver
TDI Advanced Nitrox Diver Are you looking to expand your dive time? Maybe you’re a scientific diver or photographer looking to stay in the water a little longer?The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 percent within your current certification level to a maximum depth of 40 metres/130 feet during dives that do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career. TDI Advanced Nitrox is also a must for SCR or CCR divers. Who this course is for: • The certified nitrox diver looking to expand their understanding of nitrox mixtures containing more than 40% oxygen • The certified nitrox diver looking to expand their in-water skills • The certified diver who has interest in moving forward with technical diving education Course prerequisites (these requirements must be met prior to the start of the course): • Minimum age 18, 15 with parental consent • Minimum certification of TDI Nitrox Diver or equivalent • Proof of 25 logged open water dives What you can expect to learn: Advanced Nitrox picks up where TDI Nitrox leaves off and offers a more in-depth look at diving with nitrox including: • Physics and physiology relating to diving with gas mixes containing more than 40% oxygen • Gas planning, dive tables, dive computers, oxygen limitations, nitrogen limitations • Equipment considerations, cylinder labeling, analyzing nitrox mixtures, gas blending procedures, -

Gunderboom Technology & Projects Overview
1050 Central Park Drive Sanford, FL 32771 Toll Free 888-345-2666 (BOOM) Tel 407-548-2200 Fax 407-548-2230 www.gunderboom.com Gunderboom Technology & Projects Overview Technology Overview Gunderboom, Inc. provides project specific, Engineered Aquatic Filter Barrier systems. The Gunderboom team designs barrier systems individually for each project that takes into consideration all the parameters of the site, project goals, physical site characteristics, “means and methods” and dynamic forces that will be transmitted into the barrier. That design is then fabricated in the Gunderboom facility under direct supervision of the design engineers. The Gunderboom fabrication facility was purpose built to assemble these special barrier systems so that the very high tensile strengths required can be achieved. It is not uncommon for connection/mooring point design loads, as an example, to reach 50,000 lbs and be 1.5” thick when all the elements are combined together (See Attachment A – GeoComposite Example). Typically, the Aquatic Filter Barrier can be described as a full depth, permeable barrier constructed of “GeoComposites” (either floating or fixed) that allows water to pass while retaining/excluding, from side to side, suspended sediments (including contaminated sediments or sediments that carry bacteria), fish/larvae/eggs or sound. In certain applications these barrier systems may be impermeable, or partially impermeable to accommodate differing strata within the water body. There are also some cases where the barriers have not been full water depth, again for site specific requirements.
