In our society there are certainly few events which require lot of audience, but the problem is not the audience but the limit which should be there in order to control the access of the audience. For example: there is a concert going on, definitely without audience how come a concert can even be imagined? Not possible correct? Hence the audience is there to applaud and cheer the artist and to make the event more and more better. Now imagine that, suddenly after watching the most favorite artist performing crowd went wild and since there was no limitation or barrier defined they went on the stage to hug ‘Justin Beiber’? Imagine how bad it will be for the organizer, artist and for the overall event.
Ok! So there are certainly some measures which can be taken to avoid such situations, the best thing is to assign security officers around the stage in order to barricade the audience. Still there is one thing which one has to install there before time in order to let the audience know their boundaries (beyond which they are not allowed, otherwise it will be called trespassing). Why they make small fences around the garden area of course any adult can jump over and get inside but, that is a psychological barrier to tell everyone that this is restricted. These items are called ‘crowd control barriers’ also known as barricades, there are so many variations available out there called bike barriers etc. If one has to examine the crowd control barriers Albury it can be seen easily in any sports even, yes those steel made sleek stands which are movable but provides a psychological barrier to the people. The purpose of the barriers is not to stop the audience physically as those stands can be moved very easily, but in order to tell them that they cannot come across the barrier and they have to stay behind the stands. There are some other materials too lighter weight sometimes made of plastic, but the steel made are preferable in order to avoid the moving aspect due to heavy wind of something.
There are so many other purposes of those steel stands (crowd controlling barriers), they are used to make arena and areas for the event, sometimes they just install these barriers and set the stage in between just to give a sketch of no go area and the area where, the actual performance is going to take place. The standard size of the barricades is 15 to 16 guage steel tube with the diameters of 1.5 inch. In order to make it rust proof they are painted with the rust proof paints, which makes them more durable, better and solid.
