A construction contractor needed to confirm that on-tool extraction controlled respirable crystalline silica during stone cutting. Task-based personal sampling and XRD analysis confirmed exposures below 0.1 mg/m3 and identified one operation needing additional control.
01
Silica monitoring on a fit-out project
02
Welding fume in a fabrication shop
Following the 2019 HSE reclassification, a steel fabricator commissioned welding fume monitoring with metals analysis. The results justified upgraded LEV and an RPE programme, and demonstrated exposures driven to as low as reasonably practicable.
03
Gas monitoring at a process plant
A chemical processor required confined space and workplace gas monitoring around dosing equipment. Continuous logging detectors confirmed safe entry conditions and quantified short-term exposure peaks against EH40 STELs.
