About the Seminar

Safety cabinets are the most important type of containment equipment protecting personnel from exposure to biological hazards in the laboratory. However, they are frequently misunderstood. Confusions commonly exist, for example, among different classes of Safety Cabinets, and even between other types of laboratory enclosures (such as Fume Hoods and Laminar Flow Cabinets). Furthermore, safety cabinets are sensitive equipment requiring special maintenance and care (not just filter changes!) - working safely inside a cabinet thus requires complete understanding by the user of the principles on which they operate.

This Esco seminar is designed to educate participants in these issues, to promote a better overall understanding of safety cabinets and hence safer working techniques. It is taught at an introductory level assuming no prior knowledge and is organised primarily in cooperation with Esco distributors around the world. The focus of this seminar is on the Class II Biohazard Safety Cabinet which is the most common type of system in use today around the world. Attendees will get to see up close an actual working Esco Class II safety cabinet during the seminar.

Who Should Attend?

The primary audience for this program is Biohazard Safety Cabinet users, as well as laboratory scientists, safety officers, industrial hygienists, facilities managers and biosafety officers. In addition to the useful take-home course materials, participants will also presented with a Certificate of Attendance.


Participants will be able to:

  • Learn the background of clean air technology, the need for clean air and how clean air is achieved using HEPA/ULPA filters.
  • Understand the definition and principle of laminar air flow and its importance in Laminar Flow Cabinets and Biological Safety Cabinets.
  • Distinguish the key differences between Laminar Flow Cabinets and Biological Safety Cabinets in terms of their application suitability and working principles and hence be able to decide the appropriate equipment for their use.
  • Understand how to operate cabinets effectively and safely and to be aware of proper maintenance procedures.
