Why Extraction Arms Matter in Laboratory Safety

In UK laboratories, extraction arms are one of the most effective ways to protect staff and maintain compliance with safety regulations. As part of a well-designed Local Exhaust Ventilation (LEV) system, they capture harmful fumes, vapours, and dust directly at the source — preventing dangerous contaminants from spreading through the lab environment.

The Role of Extraction Arms in LEV Systems

Extraction arms are flexible, movable hoods designed to target pollutants where they are released. This approach is supported by the HSE COSHH Regulations, which require employers to control exposure to hazardous substances.

By positioning an extraction arm close to experiments, weighing stations, or mixing areas, airborne contaminants are efficiently drawn into ductwork and filtration units. The process is explained in detail within HSG258: Controlling Airborne Contaminants at Work, the UK’s core guidance for LEV systems.

Why Extraction Arms Improve Laboratory Safety

Whether handling solvents, fine powders, or chemical vapours, laboratories face daily exposure risks. Installing extraction arms in laboratories helps to:

  • Safeguard staff health and wellbeing

  • Maintain COSHH and LEV compliance

  • Improve laboratory air quality and cleanliness

  • Meet international safety benchmarks such as BS EN 14175

Best Practice for Safe and Compliant Laboratories

Beyond compliance, implementing extraction arms reflects best practice in laboratory safety. Resources such as the British Occupational Hygiene Society (BOHS) and UK Government Health & Safety guidance provide further insights into creating safer workplaces.

By combining extraction arms with wider LEV systems, laboratories can reduce exposure risks, meet legal obligations, and provide a safer environment for staff and research.
