Is it acceptable for a flagger's clothing to be blue or brown during work?

The correct answer is that it is not acceptable for a flagger's clothing to be blue or brown during work. This is primarily due to safety guidelines and regulations that dictate the use of high-visibility clothing for individuals working in areas where they are at risk of being struck by vehicles or equipment.

High-visibility clothing, which typically includes colors such as fluorescent yellow, lime green, or orange, is designed to make workers easily seen by passing motorists and equipment operators, especially in low-light conditions or during periods of high traffic. Blue and brown are not considered high-visibility colors and would not effectively alert drivers to the presence of a flagger, thereby increasing the risk of accidents.

In contexts like traffic control or construction, it is crucial for flaggers to wear approved apparel that conforms to applicable safety standards, ensuring that they remain visible to all moving vehicles. Therefore, the garment colors specified in the question do not align with safety practices, corroborating the assertion that such colors are not acceptable for flaggers.
