Ergonomics Awareness Training for Supervisors Practice Test

What is a recommended method to help reduce the risk of white finger?

1. Dampen vibration transmission from the tool to the hand

2. Increase the duration of tool usage

3. Wear thicker gloves for insulation

4. Use tools with higher vibrations

The correct answer is: Dampen vibration transmission from the tool to the hand

Damping vibration transmission from the tool to the hand is a recommended method to help reduce the risk of white finger, which is also known as hand-arm vibration syndrome (HAVS). This condition is caused by prolonged exposure to hand-arm vibrations from power tools and machinery. By using techniques and tools designed to minimize the transfer of vibrations to the hand, workers can significantly reduce the likelihood of developing sensation loss and vascular changes associated with white finger. This method can involve utilizing tools specifically designed with built-in vibration dampening systems or applying vibration-reducing gloves that can absorb some of the energy transmitted from the tool. The goal is to lower the intensity of vibrations experienced through the hands and fingers during use, which directly addresses one of the primary causes of this condition. Increasing the duration of tool usage or using tools with higher vibrations would exacerbate the risk of developing white finger, while simply wearing thicker gloves may not effectively mitigate the impact of vibrations, as they often do not have the necessary qualities to absorb vibrations effectively. Therefore, the correct approach emphasizes dampening vibrations to protect workers' health.
