Indoor Air Quality Testing in Perth
Improve Indoor Environmental Quality (IEQ) for Health, Comfort and Compliance
Indoor Environmental Quality (IEQ) measures how a building performs in relation to occupant health, comfort and efficiency. It focuses on indoor air quality (IAQ), thermal comfort, humidity control and ventilation performance. Strong IEQ improves productivity, reduces stress and helps minimise the risk of illness or injury.
At Opira, we provide professional Indoor Air Quality (IAQ) testing services in Perth. We support commercial buildings, healthcare facilities, laboratories, education sites and industrial environments across Western Australia.
Perth’s Outdoor Air Quality and Its Impact on Indoor Air
Perth is known for generally good outdoor air quality. Air conditions across Western Australia are monitored through the Western Australia Air Quality Index (AQI).
However, seasonal events can significantly affect air quality.
Bushfires and Planned Burns
Outdoor air quality in Perth is often impacted by increased levels of particulate matter, including:
- PM10
- PM2.5
These fine particles commonly arise from bushfires and planned vegetation burns. During these events, contaminants can infiltrate buildings through ventilation systems and poorly sealed structures.
Proactive air conditioning maintenance and indoor air quality testing in Perth are essential during these periods. Testing helps assess whether your HVAC system is effectively filtering and managing contaminated outdoor air.
Perth’s Climate and Indoor Environmental Performance
Scorching Summer Months
Perth’s summer climate presents additional IEQ challenges. High temperatures and low humidity can:
- Reduce occupant comfort
- Increase fatigue
- Impact workplace productivity
- Place strain on HVAC systems
If air conditioning systems are not performing optimally, indoor conditions can deteriorate quickly.
Professional IAQ testing helps determine how external climate conditions are influencing:
- Indoor temperature stability
- Relative humidity levels
- Ventilation rates
- Airborne contaminant levels
This data allows building managers to optimise system performance and improve thermal comfort.
Building Location and Pollution Exposure in Perth
The location of your building plays a critical role in indoor air quality.
Properties situated near:
- Major Perth freeways and highways
- Industrial precincts
- Manufacturing facilities
- High-traffic commercial zones
may experience higher exposure to vehicle emissions and industrial pollutants.
Perth’s wind patterns can carry airborne contaminants across significant distances. Without proper testing, these risks may go undetected.
Comprehensive indoor air quality testing in Perth can identify specific contaminants, including particulate matter, carbon dioxide, volatile organic compounds (VOCs) and other airborne pollutants. This enables clear risk identification and practical remediation strategies.

Potable Water Testing in Perth
Ensure Safe Drinking Water and Compliance with ADWG
Perth’s drinking water supply is sourced from surface water, groundwater and seawater desalination. These sources form part of Western Australia’s Integrated Water Supply System (IWSS).
While Water Corporation maintains strict controls over water quality at the supply point, risks can arise within individual buildings. This is where potable water testing in Perth becomes essential.
How Drinking Water Contamination Can Occur in Buildings
Even if water enters your building compliant with the Australian Drinking Water Guidelines (ADWG), contamination can occur internally.
Common risk points include:
- Holding tanks
- Storage vessels
- Pipework and plumbing networks
- Poorly maintained fixtures
- Low-flow or infrequently used outlets
Contaminants may leach into drinking water when:
- Water stagnates and is not flushed regularly
- The pH level is acidic (below pH 7)
- Residual disinfectant levels drop
- Plumbing materials degrade over time
Under Australian health and safety legislation, duty holders must identify and manage reasonably foreseeable risks that may impact occupant health. Routine drinking water testing is a key component of this obligation.
What Does Potable Water Testing Include?
Testing for every possible contaminant is not practical. Instead, a standard water quality assessment in Perth focuses on key parameters that indicate microbiological, chemical or physical contamination.
Heavy Metals Testing
Building pipework and storage tanks can contribute metals to the water supply. Common heavy metals tested include:
- Lead
- Copper
- Iron
- Zinc
Elevated levels may indicate corrosion or material degradation within the plumbing system.
pH Level Testing
Monitoring pH chemistry is critical. Acidic water can accelerate corrosion and increase the risk of contaminants leaching into drinking water systems.
Microbiological Testing
Bacteria can proliferate when:
- Residual chlorine levels are insufficient
- Water stagnates
- Cross contamination occurs
- Plumbing fixtures are poorly maintained
Testing identifies bacterial risks and supports early intervention.
Compliance with the Australian Drinking Water Guidelines (ADWG)
In Western Australia, Water Corporation provides assurance that water supplied to the building entry point meets the Australian Drinking Water Guidelines (ADWG) published by the National Health and Medical Research Council (NHMRC).
However, compliance at the entry point does not guarantee compliance throughout the internal plumbing network. Ongoing potable water testing in Perth buildings helps confirm that water remains safe at the point of use.

Asbestos Testing and Surveys in Perth
Asbestos Registers, Management Plans and WHS Compliance
Asbestos has generally been well managed across Perth, and many high-risk asbestos materials have been removed or appropriately controlled. However, if your workplace operates within a building constructed before 2004, an asbestos register and asbestos management plan is a legal requirement under Western Australian legislation.
Opira conducts professional asbestos testing and asbestos surveys in Perth, including buildings throughout:
- Perth CBD
- West Perth
- East Perth
- Greater metropolitan WA
Many commercial buildings constructed during the 1970s and 1980s still contain asbestos-containing materials (ACMs) within the building fabric. These materials may be present in ceilings, wall linings, plant rooms, risers, flooring and service penetrations.
Through routine asbestos inspections and audits, these materials can be effectively monitored, risks controlled and a low-risk status maintained.
Asbestos Audits and WHS Compliance in Western Australia
Each asbestos site audit conducted by Opira is designed to deliver compliant hazardous materials documentation aligned with:
- Work Health and Safety Act 2020 (WA)
- Work Health and Safety (General) Regulations 2022 (WA)
How to Manage and Control Asbestos in the Workplace – Code of Practice (Department of Mines, Industry Regulation and Safety, WA)
Our asbestos services in Perth include:
- Asbestos identification and sampling
- Laboratory analysis
- Asbestos registers
- Asbestos management plans
- Re-inspection programs
- Risk assessments
- Compliance reporting
Opira WA also works closely with licensed asbestos removal contractors to coordinate safe asbestos removal projects across Perth and surrounding regions.
If your building was constructed prior to 2004, proactive asbestos surveys in Perth are critical to ensuring regulatory compliance and protecting occupants.
CONFINED SPACE AUDIT
A confined space is determined by the hazards associated with a set of specific circumstances and not just because work is performed in a small space.
Entry into a confined space means a person’s head or upper body is in the confined space or within the boundary of the confined space.
Common confined spaces include vats, tanks, pits, pipes, ducts, flues, chimneys, silos, containers, pressure vessels, underground sewers, wet or dry wells, shafts, trenches, tunnels or other similar enclosed or partially enclosed structures.
The aim of the site audit for confined spaces in Perth is to provide confined space management documentation that meets the requirements of Western Australian work health and safety legislation.
The methodology employed by Opira WA adheres to the Code of Practice for Confined Spaces 2020 and the Australian/New Zealand Standard, AS/NZS 2865-2009 Confined Spaces.
A full register is provided and also including identification pictures, a generic risk assessment (including control guidance), criteria, training register and complete checklists made available to assist building manager to manage the risks associated with confined spaces.
MOULD TESTING
Perth is not well recognised for mould issues due to the relatively low humidity climate, however due to faulty piping or water ingress into building structures mould can definitely be an issue for Perth residents.
The guidelines used for mould assessment are varied due to a number of factors and there is no definitive level that defines a microbial contamination. Mould testing however when conducted correctly is an indicator if current levels could pose a potential hazard to sensitive occupants.
In the presence of moisture and lack of preventive programs such as routine climate control, maintenance and cleaning, there can be contamination of mould spores throughout the indoor air and settling within dust. The combination of both viable and non viable mould spores should typically be tested to create a thorough understanding of mould levels in the indoor air.
Some useful references for mould testing and mould remediation include the following references.
- AS/NZS 3666.2:2011 Air-handling and water systems of buildings—Microbial control Part 2: Operation and maintenance.
- AIRAH: HVAC Hygiene Best Practice Guidelines, 2010
- Australian Mould Guidelines 2nd Edition (2010) The go-to guide for everything mould, Peter Kemp and Heike Neumeister-Kemp
- ANSI/IICRC S520 – Mold Remediation – Third Edition: 2015
Opira can assist with remediation advice and work with a number of mould remediators in Perth to ensure any mould testing results are adequately understood and resolved.
