Diving Standards (I.E., Code of Federal Regulations, 29.1910 Subpart T)
STANDARDS FOR THE CONDUCT OF SCIENTIFIC DIVING June 3, 2004 OFFICE OF POLAR PROGRAMS NATIONAL SCIENCE FOUNDATION 1 FOREWORD The Office of Polar Programs (OPP) of the National Science Foundation (NSF) provides support for underwater diving associated with the research activities it funds in Antarctica. The NSF/OPP’s Standards for the Conduct of Scientific Diving have been developed to ensure that all scientific diving conducted under the aegis of the Office of Polar Programs is conducted in a manner that will maximize protection of scientific divers from accidental injury or illness associated with underwater diving while optimizing the researchers’ ability to conduct research. The OPP Standards have been patterned after the American Academy of Underwater Sciences (AAUS) Standards for Scientific Diving, a document that has provided a template for scientific diving at most academic and research institutions in the United States over the last fifty years. The approach described in the AAUS Standards for Scientific Diving has been recognized by the Occupational Safety and Health Administration (OSHA) as providing an alternate means of protecting divers than their commercial diving standards (i.e., Code of Federal Regulations, 29.1910 Subpart T). There are inherent risks in underwater diving and doing so in polar regions involves additional risks because of the environmental conditions and remoteness. The OPP Standards for the Conduct of Scientific Diving provides a framework within which to manage those risks and allow underwater diving in support of the scientific enterprise in Antarctica to proceed safely. Each scientific diver should acknowledge those risks and commit to conducting their underwater diving activities in accordance with the OPP Standards. -

Training Objectives for a Diving Medical Physician
The Diving Medical Advisory Committee Training Objectives for a Diving Medicine Physician This guidance includes all the training objectives agreed by the Diving Medical Advisory Committee, the European Diving Technology Committee and the European Committee for Hyperbaric Medicine in 2011. Rev 1 - 2013 INTRODUCTION The purpose of this document is to define more closely the training objectives in diving physiology and medicine that need to be met by doctors already fully accredited or board-certified in a clinical speciality to national standards. It is based on topic headings that were originally prepared for a working group of European Diving Technology Committee (EDTC) and the European Committee of Hyperbaric Medicine (ECHM) as a guide for diving medicine some 20 years ago by J.Desola (Spain), T.Nome (Norway) & D.H.Elliott (U.K.). The training now required for medical examiners of working divers and for specialist diving medicine physicians was based on a EDTC/ECHM standard 1999 and subsequently has been enhanced by the Diving Medical Advisory Committee (DMAC), revised and agreed in principle by DMAC, EDTC and ECHM in 2010 and then ratified by EDTC and ECHM in 2011. The requirements now relate to an assessment of competence, the need for some training in occupational medicine, the need for maintenance of those skills by individual ‘refresher training’. Formal recognition of all this includes the need to involve a national authority for medical education. These objectives have been applied internationally to doctors who provide medical support to working divers. (Most recreational instructors and dive guides are, by their employment, working divers and so the guidance includes the relevant aspects of recreational diving. -
