Three Closed Transfer Systems (CTS) were evaluated for their reduction of operator exposure to plant protection products during mixing and loading: the inverted extraction systems, easyFlow M and easyconnect, and the probe extraction system, GoatThroat®. Exposure data were generated for gloves, hands, head, inner and outer body dosimeters generated in 4 European countries for high rate (Sorbitol) and low rate (Xylitol) surrogate products used by 12 operators. Exposure values were compared with predicted data using the Agricultural Operator Exposure Model as a benchmark for open pour loading (used in the EFSA Guidance). The CTS types conformed with the ISO 21191 standard for CTS performance, and their potential to significantly reduce operator exposure was confirmed in this study. There was no statistical difference in potential (naked) or actual (one layer of clothing) operator exposure using both inverted CTS types; allowing these data to be pooled. The inverted CTS types resulted in higher mean protection (> 98% potential exposure and > 95% actual exposure) than GoatThroat® (> 80% potential exposure and > 95% actual exposure). These data can be used to derive reduction factors that could be used in the AOEM model for calculations involving mitigation e.g., 0.05 for inverted CTS since they reduced exposure by > 95% and 0.3 for probe extraction CTS types. All 3 CTS significantly reduced operator exposure to products during M&L. These and future CTS types which comply with ISO 21191 standards could be considered as mitigation devices. These findings will help to build confidence of farmers to use CTS routinely, resulting in safer pesticide handling. [ABSTRACT FROM AUTHOR] |
