Overview of Exhaust Systems
As presented in the Laboratory Control and Safety Solutions Application Guide – Rev. 2, 1994 all exhaust systems for laboratory-type facilities must meet the following four fundamental requirements:
- The system capacity and air velocity must transport all hazardous airborne substances away from their origin and discharge them sufficiently high above the facility. These substances include one or a combination of chemical fumes, vapors, airborne biological substances and various particulate and radioactive elements.
- The system must not leak or allow the exhaust air stream to re-enter the facility.
- The system's components such as ducts, fans, and dampers must be able to withstand the corrosive or other adverse effects of the transported substances.
- The system operation must not generate an unacceptable sound level or excessive vibration.
In selecting an exhaust system, one must also consider: first costs, life-cycle costs, maintainability, space requirements, expansion possibilities, and component reliability (see Chapters 2 and 3). [Lunneberg, 1998]
