ABSTRACT
Glovebox glove usage has been known to impair hand strength such as maximum voluntary grip and key pinch strength. This study assesses the effects of three material properties of glovebox glove on hand strength to offer design/selection recommendations to provide effective prevention for Musculoskeletal disorders (MSDs) in the hand and wrist during glovebox operations. Three commercially available glovebox gloves, namely butyl, hypalon, and neoprene in 0.015" and 0.03" thickness were included for evaluation. The correlation matrix indicates that the grip strength is the only dependent variable that shows statistically significant correlations with most of the independent variables except friction, and quadratic and cubic components of friction variable. Thickness and pliability are inversely correlated to the maximum grip strength. Stepwise regression shows that the interaction of thickness and pliability is the only variable included in the final equation. To minimize effects of glove usage when performing glovebox tasks involving a gripping hand, material thickness and pliability parameters could be included for glove design and selection purposes to improve worker health and safety.
