How often must the helmet policies be enforced under A30?

The helmet policies under A30 must be enforced at all times, throughout the activity, to ensure the safety and protection of participants consistently. This continuous enforcement is crucial because it helps to mitigate the risk of head injuries during unforeseen incidents that can occur at any time during activities. By maintaining strict adherence to these policies at all moments, it fosters a culture of safety and vigilance among both staff and participants, reinforcing the importance of protective gear.

In contrast, the options suggesting limited enforcement, such as only during a specific month or at the beginning of a program, fail to recognize that safety measures need to be integral to every point of engagement, rather than being treated as isolated events. Weekly check-ins, while helpful for monitoring compliance, do not guarantee the immediate safety of participants during ongoing activities; therefore, they don't satisfy the requirement for continuous enforcement. The comprehensive approach of enforcing helmet policies at all times aligns with best practices in safety protocols, making the continuous enforcement the correct answer.
