When MAXIFORCE Air Lifting Bag Systems are properly used in combination with good common sense, an extremely safe method of applying force is realized. Although the following safety first list is quite extensive, the majority of the precautions are just good common sense for any personnel qualified in the use of lift bags. However, some of the precautions are not obvious and Paratech strongly recommends that all operating/assisting/maintenance personnel read and understand the complete safety first procedures in order to ensure personnel and equipment safety. Since there are four distinct operational phases of lift bag use: Prior to Inflation, During Inflation and While Inflated, During Deflation, and After Removal, the safety first list is charted to reflect these applications.

  • 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.

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.

  • Final EIS Responses to Comments 1-40
    Table 1-2. Responses to Comments Comment Response Comment/Response Number Number 1.1 The lakes in question are in our main camp area. We have operated in this area for thirty years and probably know more about the fish in these lakes than anyone associated with this ridiculous plan. These lakes have provided unequalled fishing to our guests and all others that have fished them. 1.1 This project is designed to preserve this stronghold for native westslope cutthroat trout. This project proposes to re-establish WCT populations in all treated lakes, which will maintain angling opportunities. 1.2 We feel that his plan goes against all that is held sacred in a wilderness area. … We believe the "Wilderness Act" should be respected and these areas should not be tampered with. 1.2 Native westslope cutthroat trout are considered a wilderness value. This project is designed to maintain and conserve that value. 1.3 Why should anyone be allowed to tamper with these healthy fish in order to obtain a genetically pure strain of fish? 1.3 It is the responsibility of MFWP to ensure that this species is conserved and maintained so the public of Montana can continue to use and enjoy it. The species has been at risk of hybridization for some time. MFWP has taken measures to reduce and eliminate the threats (see Section 1.2 of the DEIS). The species has been proposed for ESA listing (see Section 1.4.1 and Appendix B of the DEIS). MFWP is mandated to keep this from happening so the public does not lose the opportunity to use and enjoy WCT (see page 1-8 of the DEIS).

  • Diving Incidents Report Foreward Introduction
    APPENDIX A - DIVING INCIDENTS REPORT FOREWARD The 1992 Diving Incidents Report, produced by The British Sub-Aqua Club (BSAC) in the interest of promoting diving safety. As the Goveming Body of the sport of sub-aqua diving within the United Kingdom, the BSAC publishes this information and makes it freely available, subject to the bounds of medical confidentiality, for the benefit of all those concerned with the organisation and conduct of sport diving activities, and in particular, all divers. The BSAC Incidents Reporting Scheme has been established for some 27 years, longer than some diver training organisations. It uses information gathered from a large variety of sources, including the individuals and clubs involved, H.M. Coastguard, recompression chamber operators, the Institute of Naval Medicine and a press cuttings service. All reports received are analysed and summarised in this report with the intention of highlighting any lessons that can be learnt. The BSAC uses this information to identify any trends in diving incidents in order togive its best advice and, if necessary, introduce new training prior to these trends becoming commonplace occurrences. This year (1992) there have been 123 reports received, and it is estimated that over 1.5 million 'man-dives' have been carried out. This is an apparent 30% reduction in dives carried out when compared to 1991 ,possibly due to both the depressed state of the economy and due to the inclement weather on the South Coast for most of the year. The vast majority of these dives were carried out in complete safety and attracted no publicity.

  • Draft Environmental Impact Statement
    South Fork Flathead Watershed Westslope Cutthroat Trout Conservation Program Draft Environmental Impact Statement Responsible Agency: U.S. Department of Energy (DOE), Bonneville Power Administration (BPA) Cooperating Agencies: U.S. Department of Agriculture, Forest Service (FS) and State of Montana Fish, Wildlife, and Parks (MFWP) Department Title of Proposed Project: South Fork Flathead Watershed Westslope Cutthroat Trout Conservation Program State Involved: Montana Abstract: In cooperation with MFWP, BPA is proposing to implement a conservation program to preserve the genetic purity of the westslope cutthroat trout populations in the South Fork of the Flathead drainage. The South Fork Flathead Watershed Westslope Cutthroat Trout Conservation Program constitutes a portion of the Hungry Horse Mitigation Program. The purpose of the Hungry Horse Mitigation Program is to mitigate for the construction and operation of Hungry Horse Dam through restoring habitat, improving fish passage, protecting and recovering native fish populations, and reestablishing fish harvest opportunities. The target species for the Hungry Horse Mitigation Program are bull trout, westslope cutthroat trout, and mountain whitefish. The program is designed to preserve the genetically pure fluvial and adfluvial westslope cutthroat trout (Oncorhynchus clarki lewisi) populations in the South Fork drainage of the Flathead River. In order to accomplish the goals, MFWP is proposing to remove hybrid trout from identified lakes in the South Fork Flathead drainage on the Flathead National Forest and replace them with genetically pure native westslope cutthroat trout over the next 10-12 years. Some of these lakes occur within the Bob Marshall Wilderness and Jewel Basin Hiking Area. Currently, 21 lakes and their outflow streams with hybrid populations have been identified and are included in this proposal.

Benefit plans vary in coverage and some plans may not provide coverage for certain services discussed in the medical policies. Coverage decisions are subject to all terms and conditions of the applicable benefit plan, including specific exclusions and limitations, and to applicable state and/or federal law. Medical policy does not constitute plan authorization, nor is it an explanation of benefits. When reviewing for a Medicare beneficiary, guidance from National Coverage Determinations (NCD) and Local Coverage Determinations (LCD) supersede the Medical Policies of Blue KC. Blue KC Medical Policies are used in the absence of guidance from an NCD or LCD. Policy Blue Cross and Blue Shield of Kansas City (Blue KC) will not provide coverage for functional neuromuscular stimulation. This is considered investigational. Neuromuscular stimulation is excluded in contracts that contain an exclusion for electrical stimulation. Verify benefits to determine whether this is a benefit exclusion or investigational. When Policy Topic is covered Not Applicable When Policy Topic is not covered Neuromuscular (electrical) stimulation is considered investigational as a technique to restore function following nerve damage or nerve injury. This includes its use in the following situations: . As a technique to provide ambulation in patients with spinal cord injury; or . To provide upper extremity function in patients with nerve damage (e.g., spinal cord injury or post-stroke); or Functional Neuromuscular Electrical Stimulation 8.03.01 .

  • Severe Hypoxemia During Apnea in Humans: Influence of Cardiovascular Responses
    From the Department of Physiology and Pharmacology Section of Environmental Physiology Karolinska Institutet Stockholm, Sweden Severe hypoxemia during apnea in humans: influence of cardiovascular responses by Peter Lindholm Stockholm 2002 ABSTRACT When a diving human holds his or her breath, the heart beat slows and the blood vessels constrict in large portions of the body. In diving mammals such as seals, similar responses effectively conserve oxygen for the brain, enabling them to dive very deep and to stay underwater for a long time. The principal aim of this thesis was to study the biological significance of bradycardia (a slowing of the heart rate) and vasoconstriction during apnea in exercising humans. The question was whether these cardiovascular mechanisms also in humans would temporarily “conserve” oxygen (i.e. temporarily reduce O2 uptake in muscles etc.) and thus protect the brain from a level of hypoxia that would otherwise cause unconsciousness in a breath-hold diver. A second aim was to determine the inter-individual variation among the human subjects in terms of the degree of bradycardia during apnea, in order to explore whether the intensity of these cardiovascular responses would make some individuals more fit to survive underwater swimming and apnea than others. Our results indeed showed inter-individual differences such that a high degree of bradycardia during apnea correlated significantly with higher levels (= better conservation) of arterial oxygen saturation. Thus, the subjects with the lowest heart rates during exercise and apnea had the best preserved saturation measured with earlobe pulse oximetry. Also, we found that the cardiovascular responses to apnea in exercising humans clearly delay the development of hypoxemia by reducing the rate of uptake from the main oxygen store, i.e.
