Description
This unit specifies the skills and knowledge required to use thermal cutting and welding tools in an underwater environment.It includes preparing underwater cutting and welding tools, operating the generator, selecting appropriate work task tools and inspecting them for serviceability, and securing tools on own body throughout dive. It also includes the surface operation of the electrical generator or gas cylinders supplying the tools, recovering waste, and deservicing and storing equipment.This unit applies to persons working as Defence Work Divers, or to others working 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 would work independently performing 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.
