Ergonomics Awareness Training for Supervisors Practice Test

What ergonomic risk factor is associated with excessive typing?

1. Poor lighting

2. Excessive repetition of movements

3. Improper chair height

4. Inadequate desk space

The correct answer is: Excessive repetition of movements

Excessive typing can lead to ergonomic issues primarily due to the excessive repetition of movements. When a person types for extended periods, they repeatedly engage their fingers, hands, and wrists in the same motion. This can result in strain on muscles, tendons, and nerves, increasing the risk of repetitive strain injuries such as carpal tunnel syndrome or tendinitis. Understanding the impact of repetitive movements is crucial for developing strategies to mitigate these risks, such as implementing breaks, promoting proper posture, and encouraging the use of ergonomic keyboards that allow for more natural hand positioning. The other options, while they can contribute to discomfort or injury in a workplace, do not directly relate to the specific risk factor associated with excessive typing. Poor lighting might cause eye strain, improper chair height could lead to back pain or poor posture, and inadequate desk space can affect ergonomics in general but are not specific to the act of typing itself. Recognizing the significance of repetitive motions helps in creating interventions aimed at preventing injuries related to typing tasks.
