Which officials are needed to run a short track competition?

Red Book C5-313 lists the officials required whatever timing system is used:

• Chief Referee
• Assistant Referee(s)
• Starters (Chief and Assistants)
• Competitor Steward(s) / Competition Coordinator(s)
• Heat Box Steward
• Lap Scorer

Timing roles are added depending on the system: Chief Timer and Timers with a Chief Finish Line Judge and Finish Line Judges for manual timing; a Chief Photo Finish / E-Timer and Assistant Photo Finish for photo finish; an E-Timer for transponders or video timing. A Video Referee sits with the video review system when one is used.
