Please find attached a completed log of personal/area air sample and audio dosimetry results.
V
Of the air samples taken, one 115 minute sample taken on the Crusher Operator, T. Silva, was 2.76 f/cc (Sample 088) which is above the current OSHA 8-hour Time Weighted Average (TWA) exposure of 2.0 f/cc. The TWA for this employee was 1.39 f/cc.
L. Megargee resampled this position on 6/26 and 6/27/80 with results being 0.15 f/cc, 0.11 f/cc and 1.29 f/cc.
All other air samples taken were within the OSHA standard with only 3 samples being above 1.0 f/cc (samples were taken on the #3 Tester Operator and the Crush Operator - Samples 041, 042 and 089).
It is recommended that the areas with samples exceeding 1.0 f/cc be monitored regularly in order to be assured that the employee's exposure remains below the 2.0 f/cc level. If a level exceeding 2.0 f/cc is found, respirators are required until an acceptable level is again achieved.
The results of the audiodosimetry noise survey indicated 11 job positions with a daily dose percentage above 100% (90 dBA dosimetry).
Those positions are:
Machine Tender Line #1 Lathe Operator Line #1 Tester Operator Line #3 Lathe Operator Line #3 Tester Operator Line #3 Beller Line #3 Handler Rework Saw SI Boring Mill Operator Coupling Tester Crusher
Sample 101 Sample 109 Sample 110 Sample 111 Sample 113 Sample 114 Sample 116 Sample 119 Samples. 120 and 122 Sample 127 Samples; 132 and 133
It is recommended that hearing protection be required at these positions until proper and permanent noise controls can be instituted.
A complete survey report is forthcoming detailing sample analysis and observations.
