Reassurance air testing can be undertaken for a number of reasons but as the name implies, it is normally employed to evidence that areas are safe to occupy after planned works, where this is expected to be the case.
These air tests tend to be strategically placed to represent a worst case scenario and reflect the potential exposure to those using your premises. Normally, results are reported to the clearance indicator level of <0.01 f/cm3 air, the limit of quantification for the test using PCM (Phase Contrast Microscopy), however lower limits of detection are available and we can arrange Scanning Electron Microscope (SEM) analysis when needed. SEM is also recommended where high levels of other contaminants, primarily dusts or fumes, render analysis difficult.
