A new, practical method assesses fume cupboard performance using airflow and condition checks. This approach helps ensure a safe laboratory environment and identifies poorly functioning fume hoods for improvement.

Area of Science:

  • Laboratory Safety Engineering
  • Occupational Health and Safety

Background:

  • Assessing fume cupboard performance is complex, time-consuming, and expensive.
  • Managerial responsibility for a safe laboratory environment necessitates reliable performance evaluation methods.

Purpose of the Study:

  • To introduce a simple, practical, and cost-effective method for ranking and assessing fume cupboard installations.
  • To provide a technically defensible system for performance audits and upgrading exercises.

Main Methods:

  • Utilized flow visualization techniques to assess fume cupboard aerodynamics.
  • Measured inflow air velocity and conducted overall condition evaluations.
  • Applied the method to survey 199 fume cupboards in an academic institution.

Main Results:

  • Successfully ranked fume cupboard performance and identified poorly functioning units.
  • Highlighted specific performance characteristics of both aerodynamic and box-type fume cupboards.
  • Gained insights into user attitudes and knowledge regarding fume cupboard operation.

Conclusions:

  • The developed method offers an economically viable and technically sound approach to fume cupboard assessment.
  • The survey results provide valuable data for improving laboratory safety and training.
  • Recommended the use of such surveys to optimize fume cupboard utilization and enhance training programs for laboratory personnel.
