An overarching consideration here is the requirement to maintain accurate logs with respect to workers' compensation. Whether you are participating in any of the core functions of the fire service—whether it be emergency response, public education, training, or what have you—it's an overwhelming responsibility of those fire chiefs to maintain these records for workers' compensation. That is one of the pillars of that responsibility, and it would satisfy this interest.
