                       2.1.2.2 Local Ventilation Systems
                          Local ventilation systems (see Fig. 2.2) are used for local controlled zones.
                       These systems are air technological methods for local protection. Primarily, lo-
                       cal protection should be made using process methods such as encapsulation or
                       process modification (see "Design Methodology," Chapter 3). Another use for
                       local ventilation systems is source capturing.
