Downloaded from http://www.everyspec.com MIL-O-87226 (USAF) 30 April 1985 MILITARY SPECIFICATION OXYGEN SYSTEMS, AIRCRAFT, GENERAL SPECIFICATION FOR This specification is approved for use by the Department of the Air Force and is available for use by all Departments and Agencies of the Department of Defense 1. SCOPE 1.1 Scope. This specification establishes the development requirements and verifications for an aircraft oxygen system and its components. 1.2 Use. This specification cannot be used for contractual purposea without supplemental information relating to the unique requirements included herein. The supplemental information relates to system design around the normal and emergency mission profiles. 1.2.1 Structure. The required supplemental information is identified by blanks within the specification. Only those paragraphs applicable to the aircraft system under consideration shall be selected. Verification method(s) must be added to each selected requirement. For more effective designs, the oxygen systems are discussed in terms of aircraft missions. 1.2.2 Instructional handbook. The instructional handbook contained in Appendix A herein provides for this technical area the rationale for require- ments, guidance on document usage, and a lessons learned repository. The need for this information is identified by blanks within the generic requirements and verifications. 1.2.3 Physiological handbook. The use of oxygen on an aircraft supports the physiological requirements of crew member(s) and passenger (if applicable) for the intended missions (altitudes, air speeds and ranges). For these reasons physiological criteria is included in Appendix B for background information. 1.2.4 Existing military oxygen equipment. Existing oxygen equipment design information is provided in Appendix C. A future oxygen system or a modified existing system will usually be a composite of existing oxygen equipment and some newly developed equipment. Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: ASD/ENES, Wright-Patterson AFB, OH 45433-6503 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.

  • Ear Clearing for Non-Divers

    Ear Clearing for Non-Divers

    Scuba School Ltd – Ear Clearing for non-divers Ear clearing or clearing the ears or equalization is any of various maneuvers to equalize the pressure in the middle ear with the outside pressure, by letting air enter along the Eustachian tubes, as this does not always happen automatically when the pressure in the middle ear is lower than the outside pressure. This need can arise in scuba diving, freediving/spearfishing, skydiving, fast descent in an aircraft, fast descent in a mine cage, and being put into pressure in a caisson or similar pressure-bearing structure, or sometimes even simply travelling at fast speeds in an automobile. People who do intense weight lifting, like squats, may experience sudden conductive hearing loss due to air pressure building up inside the ear. They are advised to engage in an ear clearing method to relieve pressure, or pain if any. Methods The ears can be cleared by various methods,[5] some of which pose a distinct risk of barotrauma including perforation of the eardrum: Yawning which helps to open the eustachian tubes; Swallowing which helps to open the eustachian tubes; The "Frenzel maneuver": Using the rear part of the tongue and throat muscles, close the nostrils, and close the back of the throat as if straining to lift a weight. Then make the sound of the letter "K." This pushes the back of the tongue upward, compressing air into the openings of the eustachian tubes. "Politzerization": a medical procedure that involves inflating the middle ear by blowing air up the nose during the act of swallowing; The "Toynbee maneuver": pinching the nose and swallowing.

  • Dive Theory Guide

    Dive Theory Guide

    DIVE THEORY STUDY GUIDE by Rod Abbotson CD69259 © 2010 Dive Aqaba Guidelines for studying: Study each area in order as the theory from one subject is used to build upon the theory in the next subject. When you have completed a subject, take tests and exams in that subject to make sure you understand everything before moving on. If you try to jump around or don’t completely understand something; this can lead to gaps in your knowledge. You need to apply the knowledge in earlier sections to understand the concepts in later sections... If you study this way you will retain all of the information and you will have no problems with any PADI dive theory exams you may take in the future. Before completing the section on decompression theory and the RDP make sure you are thoroughly familiar with the RDP, both Wheel and table versions. Use the appropriate instructions for use guides which come with the product. Contents Section One PHYSICS ………………………………………………page 2 Section Two PHYSIOLOGY………………………………………….page 11 Section Three DECOMPRESSION THEORY & THE RDP….……..page 21 Section Four EQUIPMENT……………………………………………page 27 Section Five SKILLS & ENVIRONMENT…………………………...page 36 PHYSICS SECTION ONE Light: The speed of light changes as it passes through different things such as air, glass and water. This affects the way we see things underwater with a diving mask. As the light passes through the glass of the mask and the air space, the difference in speed causes the light rays to bend; this is called refraction. To the diver wearing a normal diving mask objects appear to be larger and closer than they actually are.

  • Surface-Supplied Diver Training Manual

    Surface-Supplied Diver Training Manual

    Surface-supplied Diver Training Manual Tennessee Aquarium Chattanooga, TN Published by the Diving Control Board Tennessee Aquarium Chattanooga, TN 1st Edition 2007 Purpose Surface-supplied diving is defined in the Tennessee Aquarium Diving Safety Manual (TADSM) as a diving mode in which the diver in the water is supplied from the dive location with compressed gas for breathing and is in voice communication with the tender on the surface. This definition is based upon the requirements outlined in the Occupational Safety and Health Administration’s Code of Federal Regulations. (29 CFR 1910 Subpart T) This federal law outlines the criteria for all commercial diving. The surface-supplied diving mode requires gear and techniques that are not introduced in recreational diver training. This text was designed by the Tennessee Aquarium Diving Control Board to introduce Aquarium divers to the fundamental principles associated with surface-supplied diving. This text should be accompanied by proper practical training, as outlined in Appendix A, to promote safe surface-supplied diving under the auspice of the Tennessee Aquarium. Figure 1 – Secret Reef Dive Show- A primary use of surface-supplied diving at the Tennessee Aquarium. i Introduction There are numerous advantages to surface-supplied diving that make it an excellent choice for many diving operations. First, the diver has the benefit of an unlimited air supply. With a surface-supplied diving system, a diver can theoretically stay underwater forever. Of course, in reality, there are comfort, thermal, and decompression limits. For deep technical diving, a surface-supplied rig relieves the diver of the need to carry numerous stage bottles.
