This study was conducted to evaluate vibration reduction effect of anti-vibration gloves, personal protectors for prevention of VWF (vibration-induced white finger)
Hand transmitted vibration of 8 anti-vibration gloves and 4 conventional gloves was evaluated. Using electric vibratory tools which are generating low frequency vibration, decreasing level of hand- transmitted vibration was measured [ISO 5349(1986)].
The conclusions of this study were as follows.
1) In gloves with visco elastic urethane polymer pad, hand- transmitted vibration was increased at 40 - 250 Hz (maximum value : 10.45 dB), but vibration reduction activity was increased in level more than 450 Hz. Therefore in high frequency evoking tools, anti-vibration gloves with visco elastic urethane polymer pad were recommendable.
2) Anti-vibration gloves showed the reduction effect of 2.2 dB(130.8 dB - 128.6 dB) given consideration to frequency-weighted factor, and revealed higher reduction effect than conventional gloves, which had 1.1 dB (130.8 dB - 129.7 dB) reduction effect.
3) In the frequency <60 Hz or >450 Hz, gloves had outstanding attenuation effects for the hand-transmitted vibration. On the contrary, the hand-transmitted vibration was increased to 10.45 dB by wearing gloves in the frequency range of 40- 250 Hz which have relatively high risk of vibration-induced white finger(VWF).
Neither standard vibration -measuring method nor standard for health protection were established in Korea, thus workers who have exposed to high local-vibration level in primary metal-working industry, coal-mining industry and automobile assembly line have experienced vibration-induced health problems. Therefore, the regulation for worker's exposure monitoring to local vibration and performance testing of anti-vibration should be established and followed by developing effective anti-vibration gloves for protecting workers.
Key Words : anti-vibration glove, hand-transmitted vibration, local vibration, vibratory tools, and VWF(vibration-induced white finger).
