1131NAT Certificate II in Air Conditioning Hygiene 
It is generally recognised that Australians spend 90% or more of their time indoors. Despite this, relatively little research as well as training has been done on the quality of air in our homes, schools, recreational buildings, restaurants, public buildings, offices, or inside cars. Poor indoor air quality can result in significant adverse impacts on our health and environment. Moreover, these impacts carry a significant cost burden to the economy. It is estimated that the cost of poor indoor air quality in Australia may be as high as $12 billion per year. See Department of Climate Change, Energy, the Environment and Water of Australia at https://www.dcceew.gov.au/environment/protection/air-quality/indoor-air.
Despite decades of effort by many experts and a wealth of evidence about the magnitude of the problem, the issue of indoor air quality in public buildings, including healthcare facilities, has attracted little attention. Indoor air pollution originates from both indoor and outdoor sources, and every indoor space is different, so monitoring needs to be conducted in every public indoor space. See Australian College for Infection Prevention and Control at https://www.acipc.org.au/indoor-air-quality-science-practice-legislation/.
The Certificate II in Air Conditioning Hygiene train technicians to successfully audit indoor air quality as well as sterilise building ventilation equipment in order to facilitate quality air flow. The qualification provides indoor air quality safety training to identify, prevent, and correct issues with indoor air pollutants. The training supports the VET industry in adopting eco-friendly methods in technology transfer and environmental management practices in maintaining indoor air quality. The qualification is offered under a partnership agreement with Airhygiene Training Pty Ltd (RTO No: 45782).
