Why must your sleeves be rolled down when working around aircraft?

The requirement to roll down your sleeves when working around aircraft primarily serves the purpose of protection. Having sleeves rolled down helps safeguard personnel from flying debris, which can occur during various aircraft operations. In environments where aircraft are in operation, the risk of loose objects becoming airborne is significant, and rolled sleeves can prevent skin exposure to these hazards.

Additionally, aircraft can generate heat and, in some situations, flash fires, making it essential to reduce any potential for skin exposure to flames or heat sources. By keeping sleeves down, individuals enhance their safety in potentially dangerous situations related to aircraft operations.

While compliance with uniform standards, sun protection, and mobility are all reasonable considerations, they do not address the immediate safety concerns that come with working around aircraft, which is the primary reason for the requirement.
