Your Biosafety, Our Concern

The term “containment” is used in describing safe methods for managing infectious materials in the laboratory environment. The purpose of containment is to reduce or eliminate exposure of laboratory personnel and the outside environment to potentially hazardous agents. The three elements of containment include laboratory practice and technique, safety equipment, and facility design. The risk assessment of the work to be done with a specific agent will determine the appropriate combination of these elements.

1. Laboratory Practice and Technique The most important element of containment is strict adherence to standard microbiological practices and techniques. Persons working with infectious agents must be aware of potential hazards, and must be trained and proficient in the practices and techniques required to handle such material safely. Each laboratory should develop a biosafety operations manual to minimize or eliminate exposures to these hazards.

2. Safety Equipment (Primary Barriers) Safety equipment such as BSCs, enclosed containers, safety centrifuge cup and other engineering controls designed to remove or minimize exposures to hazardous biological materials. Safety equipment also may include items for personal protection, such as gloves, coats, gowns, shoe covers, boots, respirators, face shields, safety glasses, or goggles.

3. Facility Design and Construction (Secondary Barriers) The design and construction of the facility contributes to the laboratory workers’ protection, provides a barrier to protect persons outside the laboratory, and protects persons or animals in the community from infectious agents which may be accidentally released. Laboratory management is responsible for providing commensurate with the laboratory’s function and the recommended biosafety level for the agents being manipulated. Design features of secondary barriers included specialized ventilation systems to ensure directional air flow, air treatment systems to decontaminate or remove agents from exhaust air, controlled access zones, airlocks as laboratory entrances, or separate buildings or modules to isolate the laboratory.
