Welding Fumes Monitoring Project Overview in Barnsley

We conducted a  assessment of welding fumes at a client's food production facility in Barnsley. The assessment focused on occupational exposure to hazardous substances during welding tasks. The contaminants monitored included aluminium, chromium (including hexavalent chromium), copper, iron, manganese, nickel, and zinc.

Our methodology involved the use of personal samplers and SKC total inhalable dust sampling heads to collect airborne particulates and vapours. Samples were then analysed for metals and hexavalent chromium. The findings indicated that all measured contaminant levels were significantly below Workplace Exposure Limits (WELs). The Local Exhaust Ventilation (LEV) systems effectively captured welding fumes, maintaining low exposure levels.

Based on the results, we recommend the installation of airflow indicators on LEV systems, the continued use of ESAB Sentinel A50 Air Fed Welding Helmets, and the provision of clean storage for respiratory protective equipment (RPE). Regular employee training on the use of controls and hazard awareness is also advised. The assessment confirmed that welding fumes were adequately controlled, ensuring a safe working environment.

Biological monitoring for welding fumes in Rotherham

At Sysco Environmental Ltd, we conducted biological monitoring at a site in Rotherham to assess Chromium (VI) exposure among operatives exposed to welding fumes. The methodology involved collecting and analysing a total of five urine samples for the presence of Chromium (VI), with a concentration exceeding 10 µmol/mol creatinine indicative of significant exposure.

The analysis revealed no evidence of Chromium (VI) exposure in any of the samples. The conclusions drawn from the biological monitoring indicate that the exposure of operatives to Chromium (VI) is minimal, with no indication of absorption into their bodies. Chromium (VI) and its metabolic by-products were not detected in the submitted samples, suggesting that the exposure levels are likely well below the established exposure limits.
