AIR QUALITY ASSESSMENT, Sydney Annandale
ADE’s team of air quality consultants offer a complete package of services for a wide range of clients concerned with air quality.
Clients include businesses from the manufacturing industry, utility sectors, local authorities, government or in some cases concerned
communities or people.
The objective of air quality monitoring is to ensure compliance with current standards and legislation, where air pollution in industrial processes or designated developments is a high risk.
The National Occupational Health and Safety Commission established by the Commonwealth Government issued the Exposure Standards For Atmospheric Contaminants In The Occupational Environment in 1995 in which managers and building owners are responsible for their tenants and others, who may enter their buildings.
In order to help businesses meet the standards, A. D. Envirotech Australia Pty Ltd (ADE) provides monitoring and consultancy services for all industrial sectors. Typical indoor air quality parameters monitored by ADE are:
Carbon dioxide (CO2)
- The level of carbon dioxide is a good indicator of ventilation effectiveness in buildings. Concentrations of CO2 and ventilation rates are related. The test is conducted in accordance with NIOSH Method 6603.
Carbon monoxide (CO)
- The concentrations of carbon monoxide is of particular concern in buildings. This odourless and colourless gas is a product of incomplete combustion and is present in cigarette smoke as well as in vehicle emissions. A CO concentration of 250 ppm may cause unconsciousness, and 1,000 ppm may be fatal. The test is conducted in accordance with AS 2365.2.
Inspirable and respirable dust
- The dust particles of greatest concern are very fine particles of 5 m or less in diameter. When inhaled, these particles lodge in the lungs. These particles are frequently covered by contaminants, which may have the greater health risk. The test is conducted in accordance with AS 3640.
Volatile organic compounds (VOC)
- Volatile organic compounds can be produced from paints and building materials. Cleaning and printing processes produce significant amount of VOCs. The test is conducted in accordance with AS 2986.2.
- This is a colourless gas with a suffocating odour, which is found in many products used in commercial buildings and is also a by-product of cigarette smoke. Prolonged continuous exposure to formaldehyde gas given off from particle boards or carpets can cause hypersensitivity. It has also been shown to be a lung carcinogen. The test is conducted in accordance with AS 2365.6.
- Products may still be found in buildings posing a significant health risk particularly when it is tooled, cut or sanded. Air monitoring for asbestos is the mandatory procedure during asbestos removal operations. The monitoring is conducted in accordance with the Worksafe Australia Guidance Note On The Membrane Filter Method For Estimating Airborne Asbestos Fibres 2nd Edition [NOHSC: 3003(2005)].
Ozone is formed by electrical discharges from photocopiers, laser printers, electrostatic air filters and air ionisers. It is toxic
even at low exposures. The test is conducted in accordance with NIOSH 2(S8).
In addition to the above, a typical chimney emission test may include:
- Total suspended particulates (TSP),
- chlorides and fluorides,
- polycyclic aromatic components and
- Ozone is formed by electrical discharges from photocopiers, laser printers, electrostatic air filters and air ionisers. It is toxic even at low exposures. The test is conducted in accordance with NIOSH 2(S8).
The above atmospheric contaminants have the potential to cause serious health problems and it is the employer’s responsibility to provide a safe environment for all workers. All ADE reports issued include advice and recommendations on whether environmental and/or contract standards are met and if any remedial actions are required.
