DustScanAQ conduct indoor and outdoor workplace dust surveys. We use hand-held particulate samplers in selected and representative locations to assess the concentrations of either total inhalable (TSP), thoracic (PM10), respirable (PM4) or high-risk respirable (PM2.5) dust within working areas and at varying heights. Whilst such surveys are not definitive in terms of COSHH regulations they are useful to identify key ‘dusty’ areas and processes; the location of many such dust sources and ‘dusty’ locations can be investigated during a survey.
High levels of workplace dust and fine particulates can have a serious effect on the health of staff and the efficiency of plant and equipment. Indoors, fine dust particles may remain suspended for many hours and at times accumulate in areas away from obvious point sources.
The results from workplace dust monitoring surveys can be used to map dust concentrations spatially and in 3 dimensions. Samples are carefully collected from different heights and positions to find points where dust concentrations are highest. This information can be used to help locate LEV systems and other control measures.
Recent workplace dust surveys and mapping exercises include projects for major building refurbishment works, a sheet metal fabrication factory and an incinerator bottom ash (IBA) processing facility.
