Which of the following describes a key feature of DSE assessments?

The correct answer points out a vital aspect of DSE (Display Screen Equipment) assessments, emphasizing the significance of workspace ergonomics. These assessments aim to evaluate how an individual interacts with their work environment, particularly in relation to their computer setup. Correct ergonomics can reduce the risk of strain, injury, and discomfort while enhancing productivity and efficiency. Understanding ergonomics involves knowledge of correct posture, screen height, keyboard positioning, and more, which are all critical elements in any DSE assessment.

This focus on ergonomics aligns with the purpose of DSE assessments, which is to ensure that employees are working in a setup that minimizes health risks and maximizes comfort during the use of display screen equipment. Hence, option C accurately captures a fundamental component of DSE assessments.

The other options do not hold true in a DSE context. DSE assessments are typically required rather than optional, they encompass a broader evaluation of the entire workstation—not just the computer equipment—and are not conducted on a long timescale like once a decade, as regular assessments are encouraged to keep up with changes in individual needs and technology.
