Understanding the Impact of Air Quality on Sites and Safety

Monitoring air quality is critical for maintaining safe, compliant and responsible worksites. Whether you're operating in construction, highways, demolition or industrial settings, poor air quality can pose risks to workers, stall progress and breach regulatory limits.

  • Exposure to high levels of dust and particulate matter is linked to respiratory issues and long-term health problems for workers.

  • The HSE estimates around 12,000 UK deaths each year are linked to occupational respiratory diseases.

  • CO₂, TVOCs and other gases may go undetected without continuous monitoring, creating silent risks across your site.

  • Environmental damage from airborne pollutants can lead to enforcement action, reputational harm and costly remediation.

Regulations around emissions and environmental impact are becoming tighter. Deploying environmental sensors helps you identify problem areas early, respond to exceedances quickly and prove compliance with relevant standards.

It’s a proactive step toward protecting your team, your site and your responsibilities as a contractor.

How Air Quality Monitoring Works

Air quality monitoring helps you measure and manage the presence of harmful pollutants and gases that could impact health, safety and environmental compliance.

Our sensor continuously collects data on fine particulate matter (PM1, PM2.5, PM10), CO₂, TVOC, carbon monoxide, humidity, temperature and dew point.

The device captures thousands of data points every hour, storing up to 180,000 time-stamped records for trend analysis and compliance reporting.

Information is accessed remotely via Stellifii, our online reporting platform, which is available through both web and app.

The system supports multiple protocols, including Modbus RTU/TCP and MQTT, so it can be integrated easily into site-level dashboards and wider reporting frameworks.

It’s a plug-and-play unit with minimal setup, making it ideal for temporary or mobile deployment. When dust or outdoor exposure affects readings, users can quickly swap out the filter patches to keep data accurate without downtime.

Used Where Compliance Matters

Who Should Use Air Quality Monitoring Sensors

Measuring air quality is critical for any organisation that needs to ensure compliance or protect workforce health. Typical deployment scenarios incljude:

  • Construction SitesMonitor emissions from dust-generating activities and stay compliant with environmental regulations.

  • Demolition ProjectsTrack airborne particulates during structure removal to minimise risk to nearby communities.

  • Highways and Infrastructure Works: Detect harmful pollutants from machinery and materials, particularly in enclosed or high-traffic areas.

  • Quarries and Extraction Sites: Manage particulate levels and reduce dust migration beyond site boundaries.

  • Local Authorities and Environmental Agencies Deploy at hotspots to track urban air quality trends or support public health initiatives.

If maintaining clean, compliant and safe site conditions matters to you, this system delivers the data and control you need.
