ABSTRACT
This chapter differentiates other source controls applicable to nonvolatile versus volatile sources. It focuses on nonventilation pathway controls that increase the Q apparent or the environmental dilution ratio without actually changing the amount of ventilation air supplied or exhausted. The chapter describes the effects of changing each variable within the generic evaporation equation on potential airborne exposures. Most employees need to be taught good work practices, safe ways to do their job. Automation is the use of some form of robotics. The advent of the microchip processor, its decreasing cost, and the widespread acceptance of personal computers have caused a revolution in automation. Automation is being instituted on both a small and large scale without IH impetus. It explains most of the non-ventilation controls rely on the physical principles of gases, vapors, and aerosols.
