What is the purpose of painting sunshields white on ready-service lockers?

The primary purpose of painting sunshields white on ready-service lockers is to reduce heat absorption. White surfaces reflect a significant amount of sunlight and minimize the amount of heat that is absorbed. This is particularly important in environments where equipment or materials are stored in lockers that can become excessively hot due to direct sunlight exposure. By keeping the surface temperature lower, it helps to protect the integrity of sensitive items stored in the lockers and contributes to the overall safety and efficiency of operations.

Options that focus on aesthetics, visibility, or compliance with regulations may be beneficial in certain contexts, but they do not directly address the fundamental functional purpose of the white sunshields in relation to heat management.
