Description
This unit involves the skills and knowledge required to maintain microbial control of refrigeration and air conditioning systems.It includes quality assurance and risk management compliance processes for maintenance of the air and water systems associated with refrigeration and air conditioning. It also includes working safely and to technical, quality and risk management industry standards, work specifications, maintenance schedules and sample inspections; evaluating components and completing the necessary maintenance documentation.The skills and knowledgein this unit will be applied by those cleaning and maintaining refrigeration and air conditioning chilled water, hot water or cooling tower water systems.Most state/territory jurisdictions have legislative requirements for the management of microbial control in cooling water systems to prevent the growth and transmission of Legionnaires' Disease. Permits may also be required for some work environments, such as confined spaces, working aloft, near live electrical apparatus and site rehabilitation.
