What type of personal protective equipment (PPE) is recommended for airfield drivers?

Answer: B — High-visibility vests or clothing

High-visibility vests or clothing are recommended for airfield drivers because they significantly enhance visibility, making it easier for others to see drivers in an environment where there may be a lot of movement and activity, such as on ramps and near aircraft. The airfield operates under various weather conditions and at all hours, so wearing high-visibility apparel ensures that personnel are more easily identifiable, thereby reducing the risk of accidents and ensuring overall safety for both drivers and other workers in the vicinity. Other types of personal protective equipment, while important in a range of other contexts, do not provide the same level of increased visibility that is crucial in the airfield environment. Standard work boots might offer foot protection, hard hats protect against falling objects, and face shields could guard against face injuries, but none of these items address the critical need for visibility in fast-paced, potentially hazardous conditions typical of airfield operations.
