When does a player need to wear a helmet in the live-ball area?

A player needs to wear a helmet in the live-ball area at all times to ensure their safety. This requirement is in place because a helmet provides protection against potential head injuries from foul balls, errant throws, or other unexpected plays while the game is in motion. The rules are designed to minimize risks during active gameplay, thereby preventing injuries that can occur outside of a player's active participation, such as when they are running the bases or standing in the on-deck circle.

In contrast, helmets are not required in dead ball situations since play is halted and the risk of injury from fast-moving objects is significantly lower. The rules focus on maintaining safety throughout the live-ball period, emphasizing the importance of consistent helmet usage during this time.
