What do light sources at workstations need to be selected to prevent?

Selecting light sources for workstations is essential to ensure that they provide adequate illumination without causing any negative effects on the work environment. Light sources must be chosen to prevent shadows, as shadows can obscure critical details on the electronic assemblies being inspected or worked on. Proper lighting helps ensure good visibility of components, solder joints, and other intricate details, allowing for accurate assessments of quality and adherence to standards.

When shadows are prevalent, they can hinder the worker's ability to detect defects, misalignments, or other issues that need attention. Overall, comprehensive lighting design aims to enhance visibility and reduce the likelihood of errors that might occur due to inadequate lighting conditions.

While other factors—like glare and overheating—are important to consider in a workstation environment, the primary concern highlighted in this context is the prevention of shadows, which directly impacts the performance and efficiency of the tasks being performed.
