What is a potential consequence of using hand-held and stationary tools that transmit vibration?

Hand-arm vibration syndrome (HAVS) is a serious condition associated with prolonged exposure to vibration from hand-held and stationary tools. This condition can lead to a variety of symptoms, including numbness, tingling, and pain in the hands and fingers, and can result in long-term damage to the nerves and blood vessels. Recognizing the risks of HAVS is important in an ergonomic context, as it underlines the need for proper tool selection, usage, and training to minimize exposure to harmful vibration levels.

The other options do not reflect the adverse effects of vibration exposure. Improved grip strength and increased dexterity are not outcomes associated with vibration exposure; instead, such exposure can weaken grip and coordination over time. Similarly, enhanced tool performance is not a consequence of vibration; tools that transmit excessive vibration may actually hinder performance, making them less efficient and harder to use safely. Understanding these consequences underscores the importance of implementing ergonomic practices to protect workers from the risks associated with vibration.
