Often a Chief Track Marshal's responsibilities will include the supervision and briefing of marshals for all daily activities, allocation of day-to-day marshaling duties; provision of marshal's vehicles, training of all marshals for incident handling, flag signalling, fire fighting, communications and basic track first aid as well as monitoring of health and safety on site to ensure the safety of all guests and personnel off-track. During the race the Chief Track Marshal's role is running the radio “network” and communication with all other track marshals as “net control”.
