Hazardous Substances Assessment at Saltburn-by-the-Sea Copper Foundry

We recently conducted a hazardous substances assessment at a copper foundry in Saltburn-by-the-Sea. Our focus was to evaluate employees' exposure to various harmful substances, including respirable crystalline silica, copper fumes, and general dust. Using personal and static air sampling, we measured the levels of these contaminants during typical work activities across different areas like the mould shop, cast shop, and welding bays.

The results revealed that some operatives were exposed to levels of copper fumes and inhalable dust that exceeded the Workplace Exposure Limits (WELs). Specifically, copper fumes in the casting and welding areas, and inhalable dust in the fettling area, were significantly high. We recommended improving local exhaust ventilation (LEV) systems, ensuring proper use of respiratory protective equipment (RPE), and enhancing housekeeping practices to minimise dust and fume generation.

Additionally, we suggested regular health surveillance for operatives, better training on the use of LEV systems, and adopting wet cleaning methods instead of dry sweeping. This project highlighted our commitment to ensuring a safe working environment by thoroughly assessing and managing hazardous substance exposure.
