NFPA 101, Life Safety Code, defines an Assembly Occupancy as an occupancy (1) used for a gathering of 50 or more persons for deliberation, worship, entertainment, eating, drinking, amusement, awaiting transportation, or similar uses; or (2) used as a special amusement building, regardless of occupant load (e.g. haunted house). In accordance with NFPA 101, Assembly Occupancies shall be provided with a minimum of one trained crowd manager or crowd manager supervisor. Where the occupant load exceeds 250, additional trained crowd managers shall be provided at a ratio of one crowd manager for every 250 occupants.
