Bisesi AT Piscataway copy to Subject Lead Sampling Results - Burlington Compound Plant Memo #10-80-001 M Personal and area sampling for lead dust was performed periodically at the Burlington Compound Plant from March 20, 1979 to November 11, 1980 by Sue Drost, Senior Laboratory Technician. A summary of the sampling results follows below (see attached sheets for details]: # of Different Concentration Ranges For 8-Hour TWA # Of Exposures Exposures Personal Samples Time Sampled (mg/m3) Ranges (mg/m3) Above OSHA-PEL Represented Mixers <0.01 to 0.34 Line Operators <0.01 to 0.10 Master Operators <0.1 to 0.18 Short Weight Operators <0.01 to 3.12 Foreman < 0.01 to 0.16 Bagger (no bagging All <0.02 . performed) Shipping 8 Receiving < 0.01 to 0.02 Quality Control Technician All< 0.01 Utility 0.01 to 0.07 Mill Operator All <0.01 Maintenance Mechanic <0.01 to 0.31 Yards 8 Service <0.02 to 0.04 0.02 to 0.28 0.01 to 0.08 0.10 0.09 to 0.34A 0.05 All. <0.02 0.01 <0.01 0.03 <0.01 <0.01 to 0.11 + 0.02 9 2 1 2 1 * - 2 - 13 5 1 3 1 3 1 1 1 1 3 1 *A minimum 0.10 mg/m3 8-hour TWA was indicated(sampling result represents only part of shift). +A minimum 0.11 mg/m3 8-hour TWA was indicated (sampling result represents only part of shift). AOne 8-hour TWA not reported due to insufficient sampling time. Area Samples Concentration For Time Sampled (mg/m3) 8-Hour TWA (mg/m3) # of Different Exposures Represented Quality Control Lab Warehouse - Office Warehouse - Lead Storage Maintenance Shop Mixing Floor - Line 1 Short Weights Booth All < 0.01 All < 0.01 All < 0.01 All < 0.01 0.01 to 0.27 0.49 to 1.04 < 0.01 < 0.01 < 0.01 < 0.01 0.01 to 0.22 0.50 1 1 2 1 5 1 These results indicate that 17 of 34 personal exposures to lead dust either equalled or exceeded the Occupational Safety and Health Administration (OSHA) Permissible Exposure Limit (PEL) for lead dust of 0,05 mg/m3 as a 8-hour time weighted average (TWA). Of the 17 personal exposures to lead dust that were below the OSHA-PEL, 4 exposures either equalled or exceeded the OSHA-Action Level (AL) of 0.03 mg/m3 as an 8-hour TWA, Results of the area sampling indicate that 5 of 11 area samples exceeded . the OSHA-PEL for lead dust of 0.05 mg/m3 as an 8-hour TWA. Of the 6 area COLORITE 012159 -2- 10-80-001 M samples that did not exceed the OSHA-PEL, 1 area sample exceeded the OSHA-AL. All lead dust samples were collected on Millipore 0.8 micron mixed cellulose ester filters using M5A pumps at a flow Tate of 1-3 liters per minute. The samples and blanks were then digested with high purity nitric acid and analyzed on a P-E 373 Atomic Absorption Spectrophoto meter equipped with flame. The corresponding laboratory sample num bers are 1084 - 1099, 1114 - 1130, 1135 - 1153, 1162 - 1168, 1177 1194, 1202 - 1210, 1231, 1245, 1258, 1260 - 1262, 1282 - 1287, 1292 1294, 1302 - 1308, 1312 - 1315, 1791 - 1793, 2139 - 2143, 4564 - 2490 and 4022 - 4026.
