NIOSH 1982 Dec:23 pages
In response to a request from an employee representative at the Edwin Cooper Company (SIC-2899), Sauget, Illinois, an evaluation was made of the working conditions during oil additive production. Concern had arisen due to a reported animal study of adverse effects caused by exposure to zinc dialkyl dithiophosphate (ZDDP) oil additives. Isobutanol (78831) and isopropanol (67630) levels were well below evaluation criteria. No silica polymorphs were found in the zinc-oxide bulk sample tested. The diatomaceous earth bulk sample contained mainly cristobalite (14464461). Personal breathing zone filter samples indicated zinc-oxide (1314132) levels to be very low when compared to criteria levels, the highest measured level being 0.3mg/m3. The maximum zinc (7440666) level measured was 0.167 milligrams per cubic meter (mg/m3). No major findings were noted on the medical examinations. No effect was noted on spermatogenesis or fertility in workers exposed to ZDDP as compared to those not exposed. The authors conclude that workers at this facility were not overexposed to isobutanol, isopropanol or zinc-oxide. No effects on spermatogenesis or fertility were noted. The authors recommend that care be exercised in the handling of dialkyl zinc phosphate based oil additives until more information becomes available which better defines the occupational risks involved. Good housekeeping, good personal hygiene, and personal protection should all help in keeping current exposures to a minimum. A need to improve several of the local ventilation exhaust systems at this facility was noted.
