Flash floods can arise or a fire can break out.
Emergency situations such as those are among the type of incidents that can interrupt a trade show or convention. The Kentucky Fair and Exposition Center is the sixth-largest facility in the United States, with 4 million annual visitors to its 400 acres. And the newly remodeled Kentucky International Convention Center is hosting 72 events this year in its 300,000 square feet, according to the center's promotional materials. Convention and trade show planners said they have been fortunate to avoid situations such as a major crushing or stampede injury, or a mass medical event, such as food poisoning. When it comes to emergencies, medical situations involving individuals are the most common, they said.
