This course provides comprehensive, hands-on instruction aligned with industry standards to prepare participants for the NSF 49 written and practical exams. The course offers in-depth training on BSC design, construction, functions, installation requirements, and safe operation practices.
Participants perform advanced certification procedures through practical exercises such as site assessments and airflow testing. Training includes all major NSF primary and secondary tests, including inflow and downflow velocity testing, airflow pattern testing, HEPA filter leak testing, vibration, lighting, noise level tests, and mock gas decontamination. Calculating airflow for Type B2 cabinets is also covered.
