Unit 5: Primary Barriers - Engineering Controls introduces primary barriers and their application to the control of biological agent and procedure hazards in the containment level 2 medical laboratory.  Step by step, you will learn to recognize biological hazards that required primary barriers for their control, the types of primary barriers that can be used to control these hazards and the correct use of these devices. 

Prerequisites – This unit introduces the concept of primary barriers. As you work through problems requiring the application of primary barriers to control biological hazards you will apply the skills, knowledge, and concepts you were introduced to in Units 1 to 4 for this Biosafety in Medical Microbiology Laboratories Course
