Minors must have a written parental permission. • Candidates coming from organisations other than ACUC must first complete the written examination of the ACUC Rescue Diver course. The Instructor must ensure that these candidates have all the knowledge and skills required by an ACUC Rescue Diver before they are allowed to proceed to the ACUC Divemaster course, these include the specialties of First Aid and Oxygen Provider. • Where the legislation requires it, candidates must pass a medical examination before starting any in- water portion of the course. In any case, they must sign the ACUC medical release form. CANDIDATE’S CLASSROOM TRAINING MATERIALS All candidates must be given the ACUC Divemaster Kit. If the candidates do not have the specialty of Teaching Assistant, then they must be provided also with the ACUC Teaching Techniques Manual CANDIDATE’S OPEN WATER TRAINING MATERIALS All candidates must be fully equipped according to the type of diving that is going to be done. CANDIDATE’S CERTIFICATION Candidates will be certified as ACUC Divemasters when they have complied with all the requirements. These include: • Minimum 80 Open Water Dives • Pass the ACUC Divemaster written examination Page 2 ACUC INSTRUCTOR GUIDE FOR THE DIVEMASTER COURSE • Successfully complete the Check-out dives for the ACUC Divemaster course CANDIDATE’S QUALIFICATIONS Once completed the course, the ACUC Divemaster will be able to: • Dive up to a maximum depth of 40 meters and always accompanied by at least another certified diver. • Be able to guide groups of certified divers in open water without supervision. • Be able to guide groups of student divers in open water under the direct supervision of an Instructor • Be able to teach snorkel diving without supervision • Be able to teach scuba diving with direct supervision of an Instructor, except for the program of Intro- duction to Diving in confined waters, which the Divemaster can teach without supervision or the Program of Resort Diving which the Divemaster can teach with indirect supervision of an Instructor. COURSE PURPOSE The purpose of the Divemaster course is to start the training of individuals into the teaching, diver care and group organisation areas of Scuba Diving. It is the first level of Leadership within ACUC. It is the first step beyond recreational diving, where diving start to be a professional activity rather than just a recreational activity. To be an ACUC Instructor everyone must have passed first by the ACUC Divemaster level or simi- lar level from other organisations. This course has been designed as a very safety and responsibility conscious course where the students expand on the rescue and first aid techniques learned in previous courses. Teaching Techniques and Group Care and Control Techniques are introduced. Also, decompression theory is studied in depth. Be- cause this course is not considered by ACUC anymore “Recreational Diving”, the course emphasis is not as mucho on being a “fun” course but rather the emphasis is placed in driving into the student the responsi- bility of diver safety, care and control. Only responsible individuals should take this course. Because the candidates are already divers, there is no need to wait for the end of the course in order to do the Check- out dives. Check out dives can be done right after the theory has been completed for each part. Neverthe- less, this is left at the discretion and logistics of the Instructor. INSTRUCTOR:STUDENT RATIOS Classroom theory: No maximum although 20 is recommended Pool or confined water practices: Because candidates are already experienced certified divers there is a maximum of 12 student per Instructor plus an additional 6 stu- dents per Assistant or Divemaster Check Out Dives: Because candidates are already experienced certified divers there is a maximum of 8 student per Instructor plus an additional 2 stu- dents per Assistant or Divemaster These numbers are the maximum under excellent conditions. If conditions are not optimal the Instructor must reduce the ratio according to safety considerations THEORY AND PRACTICES The minimum theory given during the course is that shown on the Divemaster manual, which is also shown in the “Minimum Theory” chapter of this guide. Although there is no set time, as a guide a duration of 13 hours of theory should be given. Supervised practices of CPR and resuscitation methods should also be done, as well as group control scenarios, in this time. If candidates do not have the Teaching Assistant Specialty, an additional 8 hours of theory should be given on this subject, using the ACUC Teaching Techniques manual for this purpose. Page 3 ACUC INSTRUCTOR GUIDE FOR THE DIVEMASTER COURSE The pool or confined water practices should be orientated to familiarize the candidates with the rescue ex- ercises and group control exercises specified in the ACUC Divemaster manual. It is estimated that at least 6 hours minimum of pool practices will be needed The open water Check out dives should be a minimum of 4 (2 hours) and should concentrate on Rescue Techniques, Dive Organisation, both above and below the water and Group Control, both above and below the water MINIMUM THEORY The minimum theory of the course is as explained in the Divemaster Manual, and is resumed next. The page number refers to the page of the Divemaster Manual where that subject is discussed (please note that page numbers might change slightly as new versions or different language versions of the manual are pro- duced). Instructors are encouraged to use the following index to develop their own lessons plans. PREFACE 5 INTRODUCTION 7 Dive Controller 7 Dive Guide 7 Divemaster 8 1.

  • Use of Surface-Supplied Gas for Scientific Diving
    In: Pollock NW, ed. Diving for Science 2011. Proceedings of the American Academy of Underwater Sciences 30th Symposium. Dauphin Island, AL: AAUS; 2011. Use of Surface-Supplied Gas for Scientific Diving Alan Humphrey1*, Scott Grossman2, Jonathan McBurney2, Sean Sheldrake3 1 USEPA, Environmental Response Team, 2890 Woodbridge Avenue, Edison, NJ 08837, USA [email protected] 2 Lockheed Martin SERAS, 2890 Woodbridge Avenue, Edison, NJ 08837, USA 3 USEPA, Region 10, 1200 6th Avenue, Suite 900, Mailstop ECL-110, Seattle, WA 98101, USA *corresponding author Abstract Many scientific diving entities face logistical challenges in their data collection, including high currents, low visibility, finite air supply, and high entanglement areas. This paper and presentation will discuss standard practices for the use of surface-supplied breathing gas for scientific applications to enhance both safety and efficiency of the scientific diver. The paper will examine the relevant regulatory requirements and applicable standards of the federal dive community (e.g., NOAA, EPA) relative to the application of scientific diving, as well as some pros/cons for the scientific diver of tether vs. surface-supply vs. free swimming. Lastly, the paper will make recommendations to advance the surface-supplied breathing gas mode within the scientific diving community. Keywords: contaminated water protocols, epa diving, federal dive programs polluted diving, surface-supplied diving, surface-supplied gas Introduction Surface-supplied diving is unique compared to free swimming scientific divers' more routine use of self-contained underwater breathing apparatus (SCUBA) to accomplish their objectives. Using surface-supplied air, the diver is provided a virtually unlimited supply of breathing gas from tanks or a compressor on the surface through a three-part umbilical consisting of a breathing gas hose, a pneumofathometer (pneumo) hose and communication line (comm line)/strength member to the diver.
