The article presents the results of conducted tests of protective gloves protecting against cuts and stabs by hand knives. Volunteers using protective gloves performed selected manual exercises, which are characteristic to the five dexterity tests. Subjective sensations of the load of the upper limb were evaluated on the basis of the developed questionnaire.
The article presents the problem of the effectiveness of protective gloves in workplaces. It was indicated what should have a protective glove ergonomic design. Also were described three main directions of developing custom research methods for objective assessment of the ergonomic hand protection.
Two mechanical methods have been developed for the characterization of the flexibility of protective gloves, a key factor affecting their degree of usefulness for workers. The principle of the first method is similar to the ASTM D 4032 standard relative to fabric stiffness and simulates the deformations encountered by gloves that are not tight fitted to the hand. The second method characterizes the flexibility of gloves that are worn tight fitted. Its validity was theoretically verified for elastomer materials. Both methods should prove themselves as valuable tools for protective glove manufacturers, allowing their existing products to be characterized in terms of flexibility and the development of new ones better fitting workers’ needs.
