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 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.
