What happens if a player removes their helmet while approaching first base?

When a player removes their helmet while approaching first base, the appropriate course of action according to NFHS rules is to issue a team warning for this violation. This is primarily a safety rule, as helmets are designed to protect players from head injuries. The initial infraction does not result in the player being declared out; instead, the warning serves as a reminder for the team to adhere to safety protocols.

Subsequent violations by that player or any other player on the team may lead to harsher consequences, such as ejection from the game. This progressive disciplinary approach emphasizes player safety and encourages teams to enforce proper conduct. In contrast, other choices do not align with the NFHS guidelines, as removing the helmet does not automatically result in the player being out, does not allow them to continue without penalty, and does not require the on-deck batter to put on their helmet immediately.
