This unit describes the performance outcomes, skills and knowledge required to complete rescues in natural flatwater swimming and recreation areas such as lakes, lagoons, dams, flatwater or slow moving rivers without rapids and non-surf beaches. It can also apply to built recreational facilities such as wave parks which replicate a natural environment. The collective term "open water" is used throughout this unit to delineate these environments from the confined nature of built aquatic facility pools and natural calm-water venues with a defined swimming area.White water and surf rescues are covered in outdoor recreation units coded SISORSC.It requires the ability to assess prevailing conditions, environmental hazards and rescuee circumstances to determine appropriate rescue actions. It covers skills to use equipment and techniques to provide prompt and effective rescue responses.It has particular application to lifeguards but can apply to other workers, including outdoor recreation leaders, who complete open water rescues. Rescuers use discretion and judgement to manage significant problems when they arise, guided by established organisational rescue procedures.The skills in this unit must be applied in accordance with Commonwealth and State or Territory legislation, Australian standards and industry codes of practice.No occupational licensing, certification or specific legislative requirements apply to this unit at the time of publication.
