The Effect of Protective Glove Exposure to Industrial Contaminants on Their Resistance to Mechanical Risks

Dolez P. I., Gauvin C., Lara J., Vu-Khanh T.

Vol. 16, No. 2

169--183

In several industrial environments, mechanical risks are often combined with various contaminants such as oils and greases, which may reduce the performance of protective gloves against mechanical hazards. However, glove properties are characterized on new and clean specimens, and little is known about their residual resistance once contaminated and over time. In this study, a series of protective gloves used in metalworking companies and garages were exposed to relevant oils and greases. Used gloves were also obtained from a food processing center and a garage. Their residual resistance to mechanical risks (cutting, puncture and tearing) was evaluated using standard test methods. Results revealed in some instances a large decrease in resistance to mechanical risks. Since a corresponding change in the material aspect may not always be easily observable, this may lead to serious safety breaches. These findings demonstrate the need to further the research in this domain.

Evaluation of the Flexibility of Protective Gloves

Harrabi L., Dolez P. I., Vu-Khanh T., Lara J.

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.
