Organizing a public event requires careful planning. One of the main concerns of event organizers is the safety of those who will attend the event. In events like a movie premiere where a large crowd is expected, event organizers should be able to anticipate the size of the crowd and their behavior. The organizers should make sure that they have all the necessary crowd control equipment at the venue such as stanchions, velvet ropes and retractable barriers. These crowd control equipment can help them ensure the safety of everyone and the success of the event itself.
