IICRC Certified Firm

Clean-Air Australia is an IICRC Certified Firm with IICRC Certified Technicians

The IICRC is an American National Standards Institute (ANSI) member and accredited standards developer. ANSI is responsible for overseeing the development of national consensus standards and verifying that the requirements for due process, consensus, and other criteria for approval have been met by the standard’s developer.

IICRC Certified Firms operate under the IICRC's standard of care in the inspection, cleaning, and restoration industries. IICRC Certified Firms are sought after for their industry knowledge and technical expertise, encouraging their technicians to further their career through IICRC education and training.

Relevant Standards include: 

ANSI/IICRC S520

A procedural standard and reference guide for the remediation of mould damaged structures and contents. The ANSI/IICRC S520 is based on reliable remediation and restoration principles, research and practical experience and attempts to combine essential academic principles with practical elements of water damage restoration for technicians facing “real-life” mould remediation challenges. The S520 and R520 are written for use by those involved in the mould remediation industry, and is the result of collaboration among microbiologists and other scientists, public health professionals, industrial hygienists, remediation contractors, restoration service companies, cleaning and restoration training schools and trade associations that service the professional restoration industry, allied trade-persons and others with related professional and practical experience.

CDC Aligned

Centres for Disease Control and Prevention

The National Institute for Occupational Safety and Health (NIOSH)

We refer to CDC guidance for infection control measures, Indoor Environmental Quality and HVAC Management

The CDC site resources from bodies such as The American National Standards Institute (ANSI) and ASHRAE which have developed consensus standards and guidelines for HVAC systems. For example, ASHRAE notes in Informative Appendix D to ANSI/ASHRAE Standard 62.1-2016: Ventilation for Acceptable Indoor Air Quality external icon that indoor CO2 concentrations no greater than 700 parts per million (ppm) above outdoor CO2 concentrations will satisfy a substantial majority (about 80%) of occupants.

The CDC and NIOSH offers critical guidelines for understanding the sources of indoor environmental contaminants and how controlling them can help prevent or resolve building-related symptoms in workers. It covers Dampness and Mould in Buildings, Building Ventilation, Construction and Renovation, Chemicals and Odours, Health Hazard Evaluations. We also refer to their guidelines for post Storm and Flood Remediation.

ANSI/ASHRAE Standards

ANSI/ASHRAE Standards 62.1 and 62.2

The recognised standards for ventilation system design and acceptable indoor air quality (IAQ). Expanded and revised for 2019, both standards specify minimum ventilation rates and other measures in order to minimise adverse health effects for occupants.

ASHRAE provide technical resources for infection control and outbreak guidelines, EPA recognised documents and standards of practice. 

“This letter is to recognize and express deep appreciation for the work of the [Epidemic] Task Force. In March of 2020, ASHRAE was among the first major organizations to publicly recognize the potential for transmission of the SARSCoV-2 virus in indoor air. ASHRAE leaders promptly put together an Epidemic Task Force to provide and consolidate technical resources to help address the COVID-19 pandemic. These technical resources on how to manage and upgrade ventilation and other building systems in a variety of built environments provided critical information and guidance to the general public, building managers and owners, government agencies, and a myriad of other stakeholders across the globe.”

World Health Organisation (WHO)

“The right to healthy indoor air” and in particular with Principle 6, which states that “Under the principle of accountability, all relevant organisations should establish explicit criteria for evaluating and assessing building air quality and its impact on the health of
the population and on the environment.” 

Knowledge of indoor air quality, its health significance and the factors that cause poor quality are key to enabling action by relevant stakeholders – including building owners, developers, users and occupants – to maintain clean indoor air. Many of these actions are beyond the power of the individual building user and must be taken by public authorities through the relevant regulatory measures concerning building design, construction and materials, and through adequate housing and occupancy policies. The criteria for what constitutes healthy indoor air quality provided by these guidelines are therefore essential to prevent disease related to indoor air pollution.
