What is Indoor Air Quality?
Indoor air quality is an important aspect of maintaining a healthy and safe environment for your home or business. Poor indoor air quality can lead to health problems, discomfort, and reduced productivity. An indoor air quality assessment can help identify potential sources of pollution and recommend solutions to improve air quality.
Our indoor air quality assessments provide comprehensive testing and analysis of the air quality in your space. We use state-of-the-art equipment and techniques to measure a variety of pollutants, including particulate matter, volatile organic compounds, carbon dioxide, and humidity levels. Our assessments are tailored to meet the specific needs of your space, whether it's a home, office, school, or other type of building.

How to assess Indoor Air Quality
ANSI/ASHRAE Standards 62.1 and 62.2 are the recognized standards for ventilation system design and acceptable indoor air quality (IAQ). ASHRAE provides guidelines for assessing indoor air quality (IAQ) in buildings, which can help building owners and managers ensure that their buildings provide a healthy indoor environment for occupants. Here are the general steps for assessing IAQ according to ASHRAE:
- Determine IAQ goals: The first step in assessing IAQ is to determine the specific goals for the assessment. This may include identifying specific pollutants of concern, setting air quality targets, and determining the scope and timeframe of the assessment.
- Conduct a site assessment: The next step is to conduct a site assessment to identify potential sources of indoor air pollution, evaluate the building's ventilation system, and identify other factors that may affect IAQ. This assessment may include a visual inspection of the building, air sampling, and other testing methods to evaluate indoor air quality.
- Analyze data: After the site assessment, the data collected needs to be analyzed to determine the sources of indoor air pollution and to evaluate the effectiveness of the building's ventilation system. This analysis should include a comparison of the results with the goals set in step 1.
- Develop a plan: Based on the results of the analysis, a plan should be developed to address any IAQ issues identified during the assessment. This may include recommendations for improving ventilation, controlling sources of pollution, and implementing air cleaning devices.
- Implement and evaluate the plan: Once the plan has been developed, it should be implemented and evaluated to determine its effectiveness in improving IAQ. This may include ongoing monitoring and testing to ensure that the building continues to meet IAQ goals over time.
WHS Approach to IAQ Assessments
Ventilation Rate Procedure
The ventilation rate procedure is a prescriptive design procedure that determines outdoor air intake rates based on space type/application, occupancy level, and floor area. The procedure is intended to be a simplified approach that can be used for any zone or system. The outdoor air intake rates are determined based on a table of values provided in the standard. The procedure ensures that an adequate amount of outdoor air is supplied to the space to dilute indoor air pollutants and maintain acceptable indoor air quality.
Indoor Air Quality Procedure
The indoor air quality procedure is a performance-based design procedure that takes into account contaminant sources, contaminant concentration limits, and level of perceived indoor air acceptability. This procedure is intended to be used for any zone or system and is a more comprehensive approach to ventilation design. The procedure requires a detailed analysis of the sources of indoor air pollution, the level of contaminants present in the space, and the desired level of indoor air quality. The analysis may include modeling of the airflow, contaminant transport, and the effectiveness of air cleaning devices. The procedure ensures that the outdoor air intake rates and other system design parameters are optimized to achieve the desired level of indoor air quality.
Proactive IAQ Assessments
Proactive IAQ assessments are performed to identify potential indoor air quality issues before they become a problem. These assessments are typically conducted on a regular basis, such as annually or biannually, to ensure that the building's ventilation system is functioning properly and providing an adequate amount of outdoor air. The proactive assessments can also identify potential sources of indoor air pollution, such as mold or chemical emissions from building materials.
Compliant Based IAQ Assessments
Complaint-based IAQ assessments are conducted when occupants of a building report symptoms that could be related to indoor air quality issues. The assessments are designed to identify the source of the problem and recommend corrective actions to improve indoor air quality. Complaint-based assessments can help identify specific problems that may be affecting a small area or a single occupant.
By offering both proactive and complaint-based assessments, Western Health and Safety can help building owners and managers maintain a healthy and comfortable indoor environment for their occupants. If you suspect that your building has indoor air quality issues, it's important to contact a professional to perform an assessment and determine the appropriate actions to take.

How can an Industrial Hygienist help?
An industrial hygienist can play a critical role in assessing and improving indoor air quality (IAQ) in a variety of settings, including workplaces, schools, and residential buildings. Here are some ways in which an industrial hygienist can help with IAQ:
- Conducting IAQ assessments: Industrial hygienists can perform comprehensive IAQ assessments to identify sources of indoor air pollution, such as mold, chemical emissions from building materials, and inadequate ventilation. These assessments involve a combination of visual inspections, air sampling, and other testing methods to evaluate indoor air quality.
- Developing IAQ management plans: Based on the results of IAQ assessments, industrial hygienists can develop management plans to address indoor air quality issues. These plans may include recommendations for improving ventilation, controlling sources of pollution, and implementing air cleaning devices.
- Conducting training: Industrial hygienists can provide training to building occupants on how to maintain good indoor air quality. This may include education on proper cleaning techniques, proper use of ventilation systems, and other practices that can help improve indoor air quality.
- Conducting compliance audits: Industrial hygienists can perform compliance audits to ensure that buildings meet regulatory requirements for indoor air quality. This can include evaluating ventilation systems, air quality monitoring, and other measures to ensure that buildings meet the required standards.
