This Local Exhaust Ventilation (LEV) Examination and Testing project carried out in Southampton focused on reviewing how effectively the site’s existing extraction systems were working to control airborne contaminants generated during everyday production activities.
The main aim of the assessment was to understand whether the LEV systems currently in place were helping to capture vapours and dust at source before they could spread into the wider workplace environment. A number of systems across different operational areas were examined to get a clearer picture of how well they were performing during normal working conditions.
From general observations made during the survey, the systems were found to be operating at the time of inspection, although some were not performing quite as effectively as intended. In certain areas, this could mean that airborne substances may not always be fully captured before entering the breathing zone of nearby employees, particularly when processes are opened or adjusted during routine tasks.
The project also highlighted how regular maintenance, employee training, and simple system adjustments — like improving positioning or reducing airflow obstructions — could help improve overall system performance.
Overall, the assessment provides a useful snapshot of LEV effectiveness at the time of testing and highlights practical steps to better manage workplace exposure moving forward.
