Why are brightly colored helmets often preferred on construction sites?

Brightly colored helmets are often preferred on construction sites primarily because they significantly enhance visibility, thereby improving safety by making workers more noticeable to others. In environments where heavy machinery operates and many workers are present, having a helmet that stands out helps prevent accidents. Increased visibility aids in ensuring that workers can be seen from various distances and angles, particularly in low-light conditions or among the clutter that is common on construction sites.

While factors like cost, comfort, and heat reduction may have some relevance in the overall selection of a helmet, they are not the primary reasons for choosing brightly colored helmets. The focus on visibility is paramount, as the primary goal in a construction environment is to maintain a safe atmosphere where all personnel can work without the increased risk of accidents related to visibility.
