Fundamentals of Working Safely in a Biological Safety Cabinet (BSC)


A biological safety cabinet (BSC) is the primary means of containment developed for working safely with infectious microorganisms. Class II BSCs, the most common cabinets used in laboratories, are designed to provide personnel protection (for you and those around you), product protection (for your samples), and environmental protection.

This basic-level eLearning course provides information on the safe use of Class II biological safety cabinets. Topics covered include major parts of a BSC, how a BSC works, how to work safely inside a BSC, and what to do if there is an emergency while working in a BSC. Videos, interactive exercises, job aids, and a modifiable checklist template are included in the course to enhance the learning experience.


This online course is designed for public health and clinical laboratory staff, safety professionals, and persons interested in the safe use of biological safety cabinets.


Course content is closed captioned, where applicable, and optimized for a screen reader.
