Review of Diving Conditions and On-Site Fist Aid AT4


Role of the Advanced Diver - Theory Lesson AT1

  • Lesson Objectives
    • The Advanced Diver Course covers diving and marshalling in more challenging conditions and for unknown locations. Extending a diver's own experience supports not only being able to lead other divers who are similarly progressing their experience, but it also broadens the role that they will play in a branch.
      This lesson looks at the role of the Advanced Diver as a senior diver and dive marshal. It introduces them to the identification of unknown sites from charts and from other information, the planning needed to dive these sites and an introduction to weather to help anticipate conditions for diving them.
  • Achievement Targets
    At the end of this lesson students will:
    • Understand that the role of the Advanced Diver includes developing their own diving, planning and marshalling skills
    • Understand that doing so will not only support their status as a role model for all other divers and dive marshals in the branch but to those outside the branch too.
    • Understand that risk assessment is inherent in dive planning
    • Understand that the site may put constraints on the level of diver able to participate in the dive, as well as other constraints on the numbers of divers able to dive the site, e.g. boat space or availability
    • Understand how to assess an unknown site's conditions from use of charts, tide tables and other information.
    • Understand how to determine the depth and tidal flow on a site at a given time
    • Understand the basic principles of weather patterns to be able to anticipate conditions for planned dives from weather forecast information
  • The following items will be needed:
    • Charts and Chart 5011. Copy of tide tables relevant to the charts being used

    Advanced Diving - Theory Lesson AT2

  • Lesson Objectives
    • Advanced Divers will be continuing to extend their diving experience and this lesson emphasises the importance of planning, anticipation and preparation both from the diver's perspective and of equipment considerations. Additional equipment to support advanced dives, decompression and searches is also covered. Advanced Divers may be diving with divers using other equipment for which they have received additional training such as Nitrox, rebreathers, Trimix and full face masks. Some Advanced Divers may already have completed such additional training but the lesson covers the various areas for general awareness and introduces the variety of choice of equipment and diving gas available to recreational divers. Whatever route an Advanced Diver chooses to follow, the core diving skills remain the same, all training within the BSAC is designed to offer its members a platform from which future choices can be made if they so wish.
  • Achievement Targets
    At the end of this lesson students should:
    • Understand that extending experience, whether by deeper or more challenging diving, requires planning, anticipation, awareness and responsibility
    • Understand that extending experience as Advanced Divers requires personal assessment to ensure that the diver is prepared and ready to undertake a dive
    • Understand that to extend experience in deeper or more challenging conditions requires personal equipment that ensures adequate gas supply and independent back up systems
    • Understand that equipment configurations are personal to the diver and their dive needs, but familiarity with all their equipment is an absolute 'must'
    • Understand that additional support equipment may be needed for deeper or more challenging dives to facilitate decompression obligations
    • Understand the basis of surface and underwater searches
    • Understand the different gas mixes and equipment available to recreational divers
    • Understand that as Advanced Divers, their development and enjoyment of the sport doesn't stop with this qualification. Many of the skills learned during the course and subsequently put into practice will undoubtedly put them well on the road to progressing to the highest diver grade - First Class Diver

    Organising Diving from Different Platforms - Theory Lesson AT3

  • Lesson Objectives
    • Advanced Divers are going to be marshalling a wide variety of diving and this will involve different 'diving platforms'; small boats that belong to the branch, day charter boats and live aboard charter boats - generally booked for branch expeditions or diving holidays. The Advanced Diver will, in many cases, be the senior diver and it is their responsibility that diving and associated activities are run as safely as possible. In some cases they may be the sole Dive Marshal; in others there will be additional Dive Marshals and assistant Dive Marshal support. Whether the Dive Marshal holds boat handling qualifications or not, the marshalling of boat dives includes important liaison with cox'ns and Skippers and, if on holiday, dive guides or local instructors. As a senior diver and Dive Marshal, sea awareness and being able to assist as crew is an important aspect of the Advanced Diver's overall role. Going to sea and learning from others, builds on the Advanced Diver's experience base, not just for diving but also for boat and diver management skills
  • Achievement Targets
    At the end of this lesson students should:
    • At the end of this lesson students will:
    • Understand the different types of diving platform and their associated Dive Marshalling and organisational considerations
    • For small boat diving and Cox'n liaison
    • For charter boat diving and Skipper or Dive Guide liaison
    • Understand some basic seamanship for increased awareness when marshalling from boats. This includes common nautical terms when using boats, buoyage, and introduction to the Rule of the Road.
    • Understand the importance of crewing to support any boat diving and marshalling activities including some basic ropework
  • The following items will be needed:
    • Charts, parallel ruler, dividers. Two pieces of rope per student for the knot tying practical

    Review of Diving Conditions and On-Site Fist Aid - Theory Lesson AT4

  • Lesson Objectives
    • This lesson is a review of diving related conditions and on-site oxygen first aid. Also included is a reminder of rescue management considerations including contacting the emergency services
  • Achievement Targets
    At the end of this lesson students will have reviewed:
    • General predisposing factors that can lead to diving incidents
    • Gases under pressure and their effects
    • Nitrogen - DCI, Nitrogen Narcosis
    • Oxygen - Oxygen toxicity
    • Carbon Dioxide - Carbon Dioxide toxicity
    • Carbon Monoxide - Carbon Monoxide poisoning
    • Near drowning
    • Shock
    • Missed decompression
    • The importance of administering fluids when DCI is suspected or present in a casualty
    • Using Nitrox/alternative gas supplies for use when emergency oxygen has been consumed
    • Practical use of oxygen admin equipment
    • students should be
    • competent and confident in their ability to administer oxygen to a breathing casualty and to a non-breathing casualty with no circulation. Overview of managing a diving incident and contacting the emergency services
  • For each pair of students, the following equipment is required:
    • A resuscitation manikin
    • An oxygen administration set
    • Where there are more pairs of students than the number of manikins/oxygen administration sets available, the duration of the practical elements of this lesson should be extended pro rata, so that each student experiences the specified periods of practice. The duration of practice is very important in not just achieving, but consolidating the skill levels and hence should not be truncated.
