Indoor and Outdoor Air Quality Testing
Indoor and Outdoor air quality testing ensures a healthy living or working environment by analysing air samples to ensure they are free of contaminants. As such, 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. Thus, representative air sampling aims to indicate whether further investigation is required. As such, air quality monitoring can take place anywhere from a shipyard, industrial warehouse, schoolyard, tunnel or your home.
Typical indoor air quality parameters monitored by ADE are:
- Carbon dioxide (CO2)
- Carbon monoxide (CO)
- Nitrix oxide (NO)
- Nitrogen Dioxide (NO2)
- Inspirable and respirable dust
- Metals in Dust
- Volatile organic compounds (VOCs)
- Diesel Particulate Matter
- Temperature, Humidity, Wind speed
In addition to the above, a chimney emissions test is available. Such a test monitors the type and concentration of emission gas streams from chimney stacks or other designated emission points. Typically this would test for:
- Total suspended particulates (TSP),
- Sulphur Oxides (SOx),
- Nitrogen Oxides (NOx),
- chlorides and fluorides,
- polycyclic aromatic components and
CO, CO2, NO, NO2
Multi gas data loggers are positioned within the general working area at breathing height. The monitors are frequently monitored during the sampling period by an ADE consultant to ensure that no exceedances occur.
Total dust, lead in dust and respirable dust are sampled within the general work area. Total dust and lead in dust are sampled using the same 37 mm cellulose dust filter. Respirable dust is sampled using a SKC conductive plastic cyclone filter. Total dust of nuisance dust, targets all dust particle sizes and is also analysed for lead (Pb) in dust. Respirable dust is composed of the dust which is able to reach the lower bronchioles and alveolar regions of the lung. Air monitors for total dust/lead in dust and respirable dust are set to 2 L/min and 2.2 L/min respectively.
Diesel Particulate Matter
Diesel particulate matter is sampled by placing air monitor pumps at a rate of flow of 2.0 L/min. The air monitor was fitted with a DPM cassette and a quartz fiber, 37 mm filter as per the Workcover NSW Chemical analysis branch handbook (8th edition).
Any outdoor or indoor air quality testing complies with the following standards:
- AS 2985-2009 Workplace atmospheres – method for sampling and gravimetric determination of respirable dust
- AS 3640-2009 Workplace atmospheres – method for sampling and gravimetric determination of inhalable dust.
- Dust samples are tested as per the Workcover NSW Chemical analysis branch handbook (8th edition).
- Elemental Carbon (Diesel particulate) Method 5040.
- Exposure Standards for Atmospheric Contaminants in the Occupational Environment” (NOHSC: 3008 – 1995), 1995;
- Safe Work Australia, Guidance on the Interpretation of workplace exposure standards for airborne contaminants (2012)
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. This holds managers and building owners responsible for the health and wellbeing of their tenants and others, who may enter their buildings. 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.
As such, ADE conducts all air quality testing and monitoring in line with these air quality standards.
ADE performs Employee Exposure Assessments to determine potential exposure to certain elements (i.e., indoor air quality, noise levels, exposure to chemicals, asbestos etc.) and recommends engineering controls, personal protective equipment (PPE) or remedial action as necessary.
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.
All ADE reports issued include advice and recommendations on whether environmental and/or contract standards are met and if any remedial actions are required.
