Hand-transmitted vibration contributes to injury of the vascular, neurological, and musculoskeletal systems and is harmful for job performance of workers.
In a survey of impact wrench users working in a Korean automobile assembly line, all workers did not use anti-vibration gloves at work. Of them, 70% had not experienced anti-vibration gloves; and 83.3% of the workers usually used a cotton glove, a rubber-coated cotton glove, and combination of cotton and rubber coating gloves instead of anti-vibration glove.
The aim of this paper is to evaluate the suitability of anti-vibration gloves, cotton glove, and rubber-coated glove by using, on the basis of vibration transmissibility in accordance with International Organization for Standardization (ISO) 10819, and to examine the effect of vibration reduction on the anti-vibration gloves made of different materials.
This study targeted 24 anti-vibration gloves, 4 types of a cotton glove, a rubber-coated glove, and combination of cotton and rubber coating gloves.
This paper uses 2 ISO standards for the measurement and evaluation of hand-arm vibration. Some anti-vibration gloves can attenuate vibration, but all the anti-vibration gloves in this study do not satisfy the ISO 10819 requirements. In case of equal vibration types, the outside materials are effective in order of leather, fabrics, and rubber-coating, according to the ISO 5349 standard.
As a result of frequency analysis, the most effective material for vibration attenuation are sponge at 10 Hz or below. Rubber material is effective at 100 Hz or upper. The most effective material for vibration attenuation is gel, sponge, and rubber at whole frequency range.
In case of wearing the gloves, the vibration peak fell down from twice to 8 times, so workers can use vibration tools for more than 8 hours.
