Air Quality Monitoring Safety

Air quality monitoring on construction sites measures dust, particulate matter, and pollutant concentrations.
Monitoring is often required by planning conditions to protect neighbours from construction dust and emissions.
PM10 and PM2.5 particulate monitoring are the most common measurements required near sensitive receptors.
Monitoring equipment includes continuous real-time samplers, gravimetric filters, and weather stations.
Equipment is typically installed at site boundaries and near the closest residential or commercial receptors.
Installation and servicing of monitoring equipment may require access to elevated positions and restricted areas.
Calibration and maintenance of air quality monitors must be carried out by trained and competent technicians.
Real-time monitoring with automatic alerts allows immediate response when dust levels approach trigger thresholds.
Data must be recorded, reviewed, and reported to the local authority as required by planning conditions.
The Institute of Air Quality Management (IAQM) guidance sets the framework for construction dust monitoring.

Protect public health	Construction dust affects respiratory health — monitoring ensures dust levels remain within safe limits for neighbours.
Planning compliance	Failure to monitor as required by planning conditions can result in enforcement notices and project suspension.
Evidence of compliance	Monitoring data provides objective evidence that dust controls are effective and regulatory limits are being met.

Do

Don't

Install monitoring equipment at locations specified in the dust management plan
Calibrate all air quality monitors before deployment and at required service intervals
Review monitoring data daily and compare against agreed trigger and action levels
Alert the site manager immediately when readings approach or exceed the trigger threshold
Implement additional dust control measures when monitoring shows elevated concentrations
Wear appropriate PPE when installing or servicing equipment in active construction areas
Maintain safe access to monitoring stations including any elevated or boundary locations
Record all monitoring data, calibration certificates, and maintenance logs for audit
Report monitoring results to the local authority at the frequency required by conditions
Protect monitoring equipment from damage by site activities, plant movements, and weather

DON'T install monitoring equipment without following the approved dust management plan locations
DON'T use uncalibrated monitors as data will be unreliable and invalid for compliance purposes
DON'T ignore trigger level exceedances — implement additional dust controls immediately
DON'T allow monitoring equipment to be damaged or obstructed by construction activities
DON'T access elevated monitoring positions without following working at height procedures
DON'T delay reporting exceedances to the local authority when required by planning conditions
DON'T leave data gaps — ensure backup power and telemetry keep monitors running continuously
DON'T relocate monitoring equipment without approval from the environmental consultant
DON'T dismiss public complaints — check monitoring data to verify dust levels at the time
DON'T treat monitoring as optional when it is required by a planning condition
