The Life Cycle results on Table 5 presents each of the major life cycle stages of the rock crusher. The flows selected for this paper include NO x, SO x, CO 2, particulate matter, iron as a natural resource input, and total energy, and are presented in the first column of the table. 6 This first column contains the actual flow quantity in the appropriate units, while

Acoustic maps showing the overall sound pressure levels measured throughout a specific working area were created and provided to the mines. This paper describes the collection of the area noise data and the guidance provided by NIOSH to the mines for using the acoustic maps as a part of their comprehensive hearing conservation programs. 2.
