In October 2024, a Hazardous Substance Assessment was carried out at two facilities in Bristol to check air quality and ensure employees were not exposed to harmful substances. The focus was on areas where nutrient solutions, aerosols and airborne particles could pose potential health risks, particularly in greenhouses and growth bays where plant cultivation takes place.
The results were reassuring; all tested chemical levels were significantly below workplace safety limits, meaning there’s no immediate danger. However, elevated bacteria and mould levels were detected in some areas, likely due to the humid environment. While these readings are expected in a greenhouse setting, steps can be taken to reduce potential exposure.
The report suggested improving air circulation, maintaining strict cleaning protocols, and monitoring humidity levels to keep microbial growth under control. No respiratory protection was required, but continued training and routine monitoring were recommended to ensure a consistently safe workspace.
Overall, the facility is well-managed, but making a few simple changes will further improve air quality and worker safety. Keeping an eye on potential hazards and sticking to best practices will ensure a healthy and productive working environment for all employees.
