Restoring Indoor Air Quality After Flooding:

Cleaning and Remediation – 6 Steps for Flood-Contaminated HVAC Systems

There are no safe levels set for the occurrence of Mould. However there are IAQ Industry standards set for CFU/cm³ above which there is genuine concern for the health of inhabitants. Only a Mycologist, a Micro-biologist who is an expert in fungi & mould, can determine which moulds are harmless and which are an issue. The safest outcome is to minimise the presence of all moulds. Domestic cleaners and mould treatments are often only bleaches which may change the appearance of mould but not destroy it.

IICRC Certified Remediation Methods

Due to the wetness of the cooled air in an air conditioning system there is always an element of risk that mould may be present.

Clean-air uses a range of chemicals to eliminate mould. However the process is a time consuming one with every surface requiring multiple wet wiping to achieve success. We have taken what we have learned on Mould Remediation within HVAC systems and now apply it to more general building usage including Floors, Walls, Ceilings, Hard and Soft Furnishings. This involves drying of all materials, treatment and verification.

ⓘ Our complete remediation methods avoid cross-contamination, if not done this way mould regrowth can occur within 48-72 hours

Preventative Measures

Anti-microbial Coatings

Within HVAC ducts we use advanced anti-microbial coatings to prevent mould growth. We also use a clear coat treatment on Grilles, Registers and other surfaces.

Germicidal UVC

HVAC Coils: UVC destroys viruses, mould, bacteria and fungus in your air system, reducing occupant sickness, increasing energy efficiency and stopping mould growth.

Health Risks

Mould in your air conditioning system can lead to a wide range of illnesses. All types of mould can trigger allergic reactions in people sensitive to those substances, but some types of mould like aspergillus produce toxic compounds known as mycotoxins. These compounds can lead to serious health issues such as legionellosis, pneumonia and bleeding in the lungs. Mould found anywhere in a built environment can result in health problems, but when mould is in the air conditioning system, it can be particularly problematic. Microscopic mould spores become airborne when air blows through the ducts and then are dispersed throughout the built environment, where they can be easily inhaled or develop into new mould colonies. Infants, pregnant women, the elderly, and any persons who have an immune deficiency are most susceptible to mould-related illnesses, but even healthy, young adults can get sick.

Symptoms of mould exposure range from:

  • Headache, fatigue, shortness of breath
  • Sinus congestion, coughing and sneezing
  • Eye, nose, throat and skin irritation
  • Dizziness and nausea

Not everyone has the same sensitivity to mould so it is possible for one person to experience discomfort while others in the building or office present no symptoms whatsoever. Individuals at the greatest risk include:

  • Allergy and asthma sufferers
  • People with respiratory disease
  • People with compromised immune systems
  • Contact lens wearers

Air conditioner mould spores circulate in the air, where they may be inhaled by the room's occupants. Infants and the elderly are particularly vulnerable. Airborne mould spores may also release chemicals knows as mycotoxins. Mycotoxins are harmful compounds that cause severe illnesses.

The results of work conducted in Australian homes, hospitals and other air-conditioned buildings indicate fungi are an indoor pollutant of significant concern. Indoor Air Quality Special Interest Group, Clean Air Society of Australia and New Zealand (2002) Indoor Air Quality in Australia: A Strategy for Action, FASTS Occasional Paper Series Number 5, FASTS, Canberra Australia.

If your air conditioner is contaminated you are at risk. Clean-Air IEPs can assess, scope and remediate the source of these issues and neutralise the risk to your building occupants or employees.

A World Health Organisation report in 1995 estimated that up to one-third of buildings in industrialised countries are so-called sick buildings. In Australia, the CSIRO concluded in 1998 that this problem cost 12 billion dollars per year in lost productivity and illness. The issue of air quality is one with very real health and economic implications. It is with good reason that this topic is now among the most hotly debated in the environmental medical literature.
