An in-service fire station crew and fire truck will visit public events sponsored by a nonprofit organization, a school, or a neighborhood association. If a fire crew attends your event, they will typically remain “in service” and stage the apparatus somewhere that allows them to leave quickly if they are dispatched to an emergency. Responding to an emergency may cause the crew to be late to the event, to have to leave abruptly, or in some cases, to not show up at all.
