What is a common method for monitoring air quality in workplaces?

Employing air quality sensors and flow meters to measure ventilation effectiveness is a common and effective method for monitoring air quality in workplaces. This approach allows for real-time monitoring of various air quality parameters, such as particulate matter, volatile organic compounds, carbon dioxide levels, and humidity. By measuring these factors, businesses can assess whether their ventilation systems are operating correctly and ensure that the indoor air quality meets health and safety standards.

Air quality sensors provide quantitative data that can help identify problems in the workplace environment, allowing for prompt management interventions. Additionally, flow meters can give insights into the effectiveness of air circulation systems, ensuring that fresh air is being adequately supplied throughout the building. This proactive monitoring helps to prevent health issues among employees that could arise from poor air quality, thereby fostering a safer and more productive workplace.

The other options, while they can contribute to a healthier work environment in various ways, do not provide the same level of direct air quality assessment or monitoring capabilities. Regular employee surveys may provide subjective feedback but lack the objective data needed to address specific air quality issues. Installing large windows can improve natural lighting but does not directly influence air quality measurements. Similarly, while air purifiers can enhance air quality in confined spaces, they are not a comprehensive solution for monitoring and maintaining
