Qualification -
Unit of Competency DEFWDV001 - Dive using self-contained underwater breathing apparatus in open water to 30 metres
Description
Employability Skills
Learning Outcomes and Application This unit specifies the skills and knowledge required to dive using self-contained underwater breathing apparatus (SCUBA) in an open water environment to a depth of 30 metres.It includes planning the dive (including using decompression tables); selecting, inspecting and fitting equipment; entering the water from a range of platforms; conducting descent to, and servicing time at, the required depth. It also includes ascending (including using decompression techniques), exit from the water to the original platform, and removing and refurbishing equipment.This unit has been aligned with existing standards in the Australian Diver Accreditation Scheme (ADAS). It relates, in part, to the minimum standard for a diver using SCUBA to a depth of 30 metres. ADAS refers to this as ‘restricted’. Further experience is required to gain an ADAS ‘unrestricted’ rating.This unit was developed for Defence divers but may be applicable to anyone in this field.The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to.Persons undertaking this unit work independently and perform specific tasks in a range of contexts that could be unpredictable.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

As a minimum, assessors must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.

As a minimum, assessment must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.

Assessment must occur in workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated workplace operational situations that replicate workplace conditions.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Resources for assessment must include access to:

a range of relevant exercises, case studies and/or other simulations

relevant and appropriate materials, tools, equipment and personal protective equipment currently used in industry

ocean with a range of oceanic, diurnal and nocturnal environments

applicable documentation including organisational procedures, decompression tables, regulations, codes of practice and operation manuals.

When practicable, assessment should relate to the diver’s vocational focus.
