How many marshals must be on a post, and what equipment must it have?

Staffing (GCR 171):

• Every marshal post must be manned whenever vehicles are on track by at least 3 marshals for cars and at least 2 for motorcycles. More is strongly recommended, especially at corners where crashes are common.
• In official practice or qualifying there must be at least 1 marshal per point, provided a crash crew is on the circuit and ready to respond.
• The Clerk of the Course must confirm the minimum numbers before any session starts.
• A Post Chief must hold at least a Grade 4 licence.
• Trainees and junior marshals may not exceed 20% of the marshals on a turn.

Flag points need: a verbal link to Race Control, a full set of Appendix H flags and at least one 9 kg dry powder fire extinguisher.

Marshal points need: enough fire extinguishers; brooms, rakes and shovels; cement or other absorbent for oil spills with containers; a verbal link to Race Control; and 2 m straps for moving a motorcycle.

Post positions are set by the circuit safety inspector with the circuit's Chief Marshal and marked on the circuit licence plan. Each post must be in radio or telephone contact with the preceding post (Appendix H).
