Construction sites
Carrying out a construction site (demolition, construction, earthworks, use of motorized construction equipment, etc.) can generate numerous pollutants in the air, in particular dust (TSP), fine particles (PM10) and ultrafine particles (PM2.5) but also numerous VOCs (BTEX, hydrocarbons, etc.).
In this context, air quality on construction sites can become a crucial issue :
-
During phases and activities that generate dust in the environment and possible nuisance for local residents
-
Exposure of operators during excavation of polluted soil or in confined spaces
By setting up monitoring systems, we can quickly defuse crisis situations that could lead to site stoppage.
Airea is involved in a variety of worksite monitoring contexts:
-
Environmental monitoring :
-
Prefectoral/municipal order
-
High environmental quality (HQE®, low-nuisance worksite charter, etc.)
-
Complaints from local residents
-
-
Professional monitoring :
-
Monitoring operator exposure
-
Risk assessment of exposure to chemical agents and dusts
-
Implementation of alert procedures when threshold values are exceeded
-
Control of occupational exposure limit values (VLEP-8h, VLCT)
-
Airea has a complete instrument fleet and a monitoring solution that allows it to intervene quickly on many construction sites. The implementation of a continuous measurement system of the target pollutant(s) with the possibility of real-time monitoring allows for more efficient environmental management of the construction site, in particular by programming alarm thresholds for concentrations in the ambient air and implementing associated targeted actions.
Among the services offered, Airea carries out dust measurements using several methods depending on the context :
-
Spot measurements of total dust fallout by sedimentation in collectors (Owen or Hibernia gauges) in accordance with standard NF X43-014
-
Spot measurements of dry dust fallout by sedimentation on deposition plates (DIEM plates) in accordance with standard NF X 43-007
-
Continuous measurements of suspended particles (PM₁₀₀, PM₁₀, PM₄, PM₂₅, PM₁, ultrafine particles known as PUF) by optical system (reference instruments or micro-sensors)
-
Daily or weekly measurements of suspended particulates (PM₁₀, PM₂₅) by regulatory method (gravimetric measurement in compliance with NF EN 12341)
-
Spot measurements of suspended particulates (PM10) by indicative method (sedimentation of particles on a collector in accordance with VDI 2019:2013)
