Guide to Fume Cupboard Testing and BS14175 Compliance for Laboratory Safety


Ensuring a secure and controlled laboratory environment is paramount when handling hazardous substances. This blog provides a detailed exploration of the integrated significance of regular 14-month testing and compliance with UK Health and Safety Executive (HSE) regulations outlined in documents HSG258 and BS EN 14175 for laboratory fume cupboards.

Regular testing within the 14-month cycle is pivotal for ensuring the ongoing effectiveness of laboratory fume cupboards in controlling contaminants. This periodic assessment seamlessly integrates with the regulatory framework outlined by the HSE, providing a structured and proactive approach to safety. The synergy of the 14-month testing cycle and UK regulations, specifically the HSE documents HSG258 and BS EN 14175, establishes a robust foundation for maintaining a secure laboratory environment. Compliance with these regulations is indispensable for guaranteeing a safe working environment and mitigating risks associated with handling hazardous materials. This alignment with the 14-month testing cycle offers a comprehensive approach to identifying and rectifying potential issues promptly, thereby safeguarding the well-being of laboratory personnel.

Thorough Examination Process: The Thorough Examination Process is a critical aspect of maintaining the functionality and safety of laboratory fume cupboards. This rigorous evaluation encompasses a comprehensive assessment of multiple elements, each playing a crucial role in ensuring the overall efficacy of these essential safety mechanisms.

Face Velocity Assessment: Certified professionals conduct meticulous measurements to verify the face velocity of fume cupboards. Maintaining a minimum face velocity of 0.4 m/s across the face of the cupboard is essential for the effective containment of contaminants. Additionally, adherence to the stipulated face velocity variance of not exceeding 20% across the face of the cupboard ensures consistent performance.

Containment Evaluation: The examination process includes a thorough assessment of the containment capabilities of fume cupboards. This involves verifying that the cupboards effectively capture and control hazardous substances, preventing their release into the laboratory environment. Ensuring proper containment is crucial for the overall safety of laboratory personnel and the surrounding workspace.

Functionality Inspection: Certified professionals scrutinize the functionality of fume cupboards to ensure they operate according to the specified standards. This involves checking the functioning of components such as airflow systems, alarm systems, and emergency shutdown mechanisms. Any deviations from the prescribed functionality are promptly identified and addressed during the examination process.

Identification of Air Currents and Draughts: Regular inspections play a vital role in identifying and addressing issues such as air currents or draughts that may impact the ability of fume cupboards to control contaminants effectively. These disturbances can compromise the containment efficiency, and their identification during the examination process allows for timely corrective measures.

Periodic Maintenance Recommendations: As part of the thorough examination, certified professionals may provide recommendations for periodic maintenance activities to ensure the continuous optimal performance of fume cupboards. This proactive approach helps prevent potential issues and enhances the longevity of these safety systems.

In essence, the unified approach of combining the 14-month testing cycle with adherence to UK regulations, alongside the thorough examination process, establishes a comprehensive and proactive strategy for maintaining a safe and compliant laboratory environment. Regular testing and inspections, conducted by trained experts, form a crucial part of this strategy, contributing to the overall safety and efficiency of laboratory operations.
