ABSTRACT
This study has been done in a raajor brake-shoe factor.'. Air samples were taken and dust"nlevels determined according to OSHA code, revealing a dust load in weighting and shooting"nsaloons ranging from 2 to 16.88 mg/nr" Measurement and counting of asbestos fibers were"ndone using OSHA ID 160/ code and permissible exposure levels."nAsbestos fiber counts in sampled areas were higher than the time weighted average level"n(TWA) and even higher than action level."nParticle size distribution was also determined. It turned out that of the 3000 counted particles,"n%90 of non-fibers and %10 are fiber-shaped. Also size of %60.4 of counted fibers is lower"nthan 10 "x that %80 of them are fibers."nThe results of this study showed significantly thai the maximum pollution loads occur in the"nweighting section, especially in the mixers. Heavy pollutant load. low air flow (face velocity)"nand use of canopies with the lowest enclosure may be regarded as potential mechanisms.
