Chemical Fume Hood/ASHRAE-110 Testing

TSS offers comprehensive testing, certification, and maintenance of chemical fume hoods. All testing is performed in accordance with established TSS standard operation procedures [SOPs], which are updated to remain compliant with state, federal, and international safety guidelines as well as TSS' own stringent quality assurance systems.

Chemical fume hoods are tested in accordance with OSHA, AIHA/ANSI, SEFA, and ASHRAE.

Primary tests performed include:

• Inflow velocity profiling - assures that a safe inflow is maintained to protect the operator from the product
• Airflow smoke testing - provides a qualitative analysis of air capture at the face of the unit, thus demonstrating the unit's exposure prevention effectiveness

Optional tests include:

• Calibration of airflow monitors - testing of airflow monitors
• ANSI/ASHRAE 110 testing - provides quantitative data used to evaluate the containment performance of fume hoods. Testing includes:
• Primary testing noted above
• Local and large volume smoke visualization testing - determines the optimal fume hood sash positions and acceptable capture performance for the unit, from both inside and outside of the unit
• Cross-draft testing - measures the amount of horizontal and vertical cross-current activity at the face of the unit
• VAV (variable air-volume) testing - determines the optimal fume hood sash positions and acceptable stabilization time for the unit
• Tracer gas containment testing - verifies containments and re-entrainment of the unit by simulating a controlled chemical release inside the fume hood and monitoring outside the hood with an IR spectrophotometer

Fume hood airflow alarms:

 In accord with regulatory bodies and in keeping with fundamental laboratory safety, TSS encourages the use of a calibrated quantitative airflow monitor. Such devices are the best way to ensure your chemical fume hood is operating safely and in compliance with regulatory parameters.  For more information regarding the operational benefits of a quantitative airflow monitor over other airflow indication devices, TSS invites you to view our Fume Hood Alarm Presentation now.

To better suit your specific needs, TSS offers you a choice in airflow monitors.  Feel free to contact us today and ask about the TSS Apex Premier or TSS Apex 1000 Airflow Monitors.  We will be pleased to provide you with additional information as well as complete installation and calibration services.  You may also view additional information now, by following the links below.
