National Environmental Balancing Bureau

The seminar will provide the attendees with an introduction to laboratory HVAC concepts. This will include discussions of environmental safety enclosures, such as fume hoods, biological safety cabinets and other containment enclosures. There will be a review of the various HVAC systems that are currently employed in laboratory design. The basic operation of fume hoods and other containment enclosures such as biological safety cabinets and their respective applications and features will be presented.

 

The new NEBB Procedural Standard for Fume Hood Performance Testing will be reviewed with emphasis on the requirements for firm certification, certified professional certification, instrumentation and reporting requirements, and testing procedural requirements. Detailed presentations will be provided for the three primary fume hood performance tests: Airflow Velocity Tests, Airflow Visualization Tests and Tracer Gas Containment Tests. In addition to the presentations addressing the procedural requirements of these tests, hands-on demonstrations on operating fume hoods will be performed. The course will emphasize the testing procedures, reporting requirements and the evaluation of testing results. NEBB’s theme is “Performance Delivering Professionals”. In concert with that theme, the seminar will conclude with a session on trouble shooting fume hood issues and problem resolution.

 

Testing Overview:

The NEBB FHT discipline is similar to all of the other NEBB disciplines in that there are written and practical examinations that must be successfully completed in order to attain certified professional certification. These written and practical examinations test the knowledge, engineering application and field testing skills required to properly test the performance of fume hoods.
