Fume Hood and Air Extraction System Testing

Sampling and Testing Process

1. Pre‑inspection planning:
   • Review of existing fume hoods and extraction systems
   • Identification of critical test points
   • Planning the appropriate measurement approach
2. On‑site testing:
   • Use of advanced, calibrated measurement instruments
   • Accurate measurement of airflow velocity, volumetric flow rate, directional airflow, and noise levels
3. Data analysis:
   • Processing and evaluation of test results
   • Comparison with regulatory requirements
   • Identification of weaknesses or non‑compliance points
4. Final detailed report:
   • Clear presentation of findings
   • Professional analysis of system performance
   • Practical recommendations for improvement and optimization
   • Guidance for compliance with standards and safety requirements
