DSAT Technical Rescue Techniques distinctive specialty – minimum requirements:Program overviewThe aim of the course is to take the skills already taught during the Rescue Diver course and relate them specifically to the hazards, equipment and techniques encountered during technical diving. This document details the minimum content of a potential DSAT Technical rescue techniques Specialty. You should use the information below to develop your outline fully A distinctive may be more comprehensive than this, but not less so. It includes a series of knowledge development topics that must be included or covered at some stage, and also a series of skills that must be included at some point during the specialty. General Standards:Pre-requisites: Student: DSAT Tec 45 Diver + Rescue Diver Instructor: DSAT Tec Deep InstructorMaximum Depth: Maximum depth 20 metresRatios: maximum: 6:1 + 2 with CA Min student age: 18Minimum no. dives: 4 (inc two CW or limited OW and 2 full OW / scenario dives) Required equipment: As per Tec Deep course + min 1 stage cylinderAcademic topicsThe course should include knowledge development that includes topics such as:
Accident avoidanceRisk assessmentHow to spot an emergency situationEmergency signalling protocols (emergency buoys etc)Procedures when reacting to an emergency situationAdjusting plans to fit unexpected hazardsImportance of buddy checks and unfamiliar equipment – rebreathers, OC twinsets etcTeam diving and signalling techniques (torches etc)O2 toxicity effectsDeco logistics – hydration and air breaksSkipping deco stopsDCS typesConsiderations when raising an unconscious technical diver Egress of the technical diverMissed stop protocolReverse blockInner ear bend / vertigoIn water recompressionNeuro exam02 adminIncident managementThe Rescue Diver manual could be used as a reference tool for some of the above. Diving skillsThe following skills can be discussed and practised. These would generally take the form of an initial skill practise in confined or limited Open Water with scenarios to follow during full open water dives. Scenarios should not be practised on dives with a real deco obligation – any stops referenced in the skills below should be simulated. Typically dives should be conducted in relatively shallow water (<20 metres) particularly any skills that assisting another diver with an ascent, due to the increased possibility of a fast ascent. Skills of this nature should be conducted in water that is 12 metres or shallower. Skills should be spread over dives to avoid multiple ascents.
