What is the primary purpose of wearing a high-visibility vest while operating a dumper?

Wearing a high-visibility vest while operating a dumper primarily serves the purpose of enhancing visibility for safety. In construction and heavy machinery operations, visibility is crucial to prevent accidents and ensure that the operator is easily seen by other workers, pedestrians, and vehicles on the site. High-visibility vests are designed using bright colors and reflective materials, which significantly increase the wearer's visibility in various lighting conditions, thereby reducing the likelihood of collisions or injuries.

This safety measure is particularly important in environments where heavy machinery is in operation, as it helps to communicate the presence of the dumper operator to others nearby, thereby contributing to a safer working environment overall.
