Qppolu survey conducted April 1972: at the Miami Plastics operations. i. ^reotninp zone air samples taken on the Blending Operator's Helper revealed total dust exposures In excess of the Threshold himit Values for nuisance dust3. At tne time of tnis survey the Blending Operator'3 exposure was v.'ithin permis sable limits for nuisance dusts. Breathing zone air samples analyzed for lead revealed air concentrations at the time of this survey to be \*lthin acceptable limits, however, because lead may also enter tne uody by inrestion and eatinp is permitted in the nlendinr Department, urine samples must be obtained ana analyzed for lead to fully determine the actual extent of exposure. See Air Samplinr. Data and Recommendations. 3. The Occupational Safety and Health Act noise standard requires tnat all employees who are steadily or infrequently exposed to noise levels in excess of 90 db-A be riven annual audiometric tests. Approximately 11 employees per shift in the Extrusion, Crinalny. and Holdlnr; Departments should be riven such tests. Hoc i.ciso Survey Data and Recommendations. ^. At the time of this survey a number of safety standard deficiencies existed which warrant attention, e.. empty fire extinguishers, incorrectly guarded wall fans unoer 2 feet from the floor (main buildiny), temporary wiring on a number of machines, inappropriate feed-chute puards on one of the larye ;Tinders.

Local exhaust ventilation snould be provided for the batch weighing operation. Lry sweeping should be avoided. Wetting prior to sweeping will help, but power vacuuming is the method of preference. Vacuuming effectively cuts down on dust generation as well as being considerably more efficient. k number of methods for reducing general dustiness in this department were suggested in the Lnvironmental Hygiene durvey Report of Larch 22, 1971* It is felt tnat a number of these recommendations still warrant consideration. A urinary lean analysis program was discussed with Mr. Sosa at tne time of this survey. In summary, it was agreed that an initial set of samples from all workers in the blending department would be obtained twice, at two week intervals, for a one month period. These samples would help to establish the extent of exposure, if any. Thereafter, monthly urine samples from all workers were to be submitted for a period of at least two months. Specimens were to be taken at the plant clinic, at least -45 hours after tne start of a wor* week ana either before the start of a snlft or at a time after the employee has changed out of his work clothes sc as to avoid sample contamination. Analysis and data interpretation will be done 1-T the environmental hygiene Laboratory in hew Haven. As stated previously, tne modes of entry of lead into the boay may be by either inhalation, or ingestion. It nus been well demonstrated in the lead storage cattery Industry studies tnat ingestion can play a significant role in lead intoxication in tne absence of low air values.

To fully comply with the noise regulation however, all employ etin the above departments should be pi van annual audionetric tests. Such tests can be arranged through a local clinic or hospital. Additionally, an effort to reduce noise levels to or below SO ub~A by engineering controls should be initiated See 1S71 Lnvironir.er.tai Rypiene Survey report and appended information for noise control cn scrap {/rinders.
