All other sample results indlea.ted employee exposure levels below the PEL'S for asbestos and total particulate/graphite.

Sattelmeier M. Teodosic Discussion The remonitoring of the mixer/weigh up stations Indicated that the employees' exposure level to lead dust was at or above the permissible exposure limit (PEL) of 50 pg/m* for an 8-hour time-weighted average. These results confirm the previous survey results which demonstrated employees exposed to concentrations of lead In excess of the PEL. The plant should begin a three prong attack on the problem: 1. Explore other methods of adding the lead to the mixer. 2. Add perimeter exhaust ventilation on mixer access doors. 3. Mandatory respiratory protection NPSP 220 or equivalent. Implementation of the above recommendation will bring the plant Into complalnce with applicable regulations and reduce employee exposure level to lead dust. An employee complaint was evaluated In the Dynamometer room alleging excessive exposure levels to asbestos dust during the Bond abuse test. In addition, the Union requested the area near the employee time clocks be sampled for asbestos dust. Both sample results Indicated concentrations of asbestos dust were less than 0.1 flbers/cc, well below the PEL of 0.5 flbers/cc. Further action is not anticipated at this time. Data Sheet Trenton Chemical Plant February 12 and 21, 1985 Asbestos Permissible Exposure Limit February 12, 1985 Area Sample Bay 8 .C-l, Adjacent to employee time clocks, across from mixers 1-4 February 21. 1985 R.

Jefferson Ave., Detroit, Michigan 48214 Dear Mr. Heidmous: Enclosed is the report of findings of the Industrial Hygiene study conducted at the Trenton Chemical Plant on February 12 and 21, 1985 by A. C. Barbaglia. Mr. 6. Plckrell, the Union Member of the Local Joint Committee on Health and Safety, was informed of this study. In order to control the employees' exposure level to lead dust It was recommended that: 1. The plant install exhaust ventilation at mixer access door. 2. Mandatory respirator protection, NPSP 220 or equivalent for employees overexposed. 3. Engineering should evaluate other ways of adding lead to mixer Sincerely G.A.
