Why a theater need security metal detectors?
When taking the subway, trains and planes ， passengers need to pass security gates. So what other public places can security screening equipment be applied to ? Today, I tell you that theaters are also very important institutions that should use security equipment.
As a public entertainment venue, the grand theatre provides comprehensive entertainment services such as theater performances and movies. Due to the large flow of people entering and leaving, the security issue is a very important issue. The concert hall is crowded , and during the movie showing or play acting, the hall is dark and the audience pays attention to the stage . If there are illegal people carrying dangerous goods at this time, it is difficult to be found and it is very easy to cause massive casualties. Therefore it’s a great safety hazard in Theater.
It is difficult for people to evacuate in two aspects:
1. Large flow of people and crowded:
The current theater is not only a single place to enjoy the drama, such as Sydney Opera House has a drama hall, a movie hall, a large exhibition hall and reception hall, 65 dressing rooms, a library, an exhibition hall, an actor canteen, cafes and bars. There are more than 900 large and small rooms.
The basic elements of a theater are the performance and viewing--the stage and the auditorium. Some ancient theaters are open-air buildings, but modern theaters are mostly indoor buildings. The stage is in the center and the space for all performers and theater technical departments to work and rest is called the background;
Under normal circumstances, The audience entering the stage or the backstage is not encouraged or even prohibited. However, some audiencea are not familiar with the layout of background environment or curiosity or ignorance of this rule,At the same time,they doesn’t understand the various mechanical and electrical equipment of the theater, it is very likely that they will cause themselves or others physical injury; More, this courtesy is often forgotten in non-strict theaters or non-professional performances. This may give the criminals a chance to disturb the order and attack peaple.
2. Structure of the theater itself:
Rapid emergency evacuation of audiences is very difficult because of the structure of the theater itself, please see a set of data:
The scale of the theater building can be divided into:
Extra large: more than 1,601seats
Large: 1201-1600 seats
Medium: 801-1200 seats
Small: 300-800 seats
That is to say, the smallest theater is likely to have 300 people at the same time. In such a closed space and A frantic atmosphere, if there is explosives, How many people can escape?
The nearly vertical stands meet the needs of the concert hall. The purpose is to increase the reflection and let the sound permeate the entire concert hall. For buildings like the concert hall, acoustic design is very important.
However, the vertical connection between the layers of the concert hall is not flexible, there is no close direct connection between the layers; People is immersed in musicals. It is more difficult to recognize the existence of difficulties while distracted.
In this case, the emergency rapid evacuation effect is not as good as in fact.
- Accident that has occurred :
In America,James Holmes was convicted of murder for the 2012 attack that killed 12 at an Aurora Colo., multiplex.
In 2015, During a showing of Amy Schumer’s hit comedy Trainwreck in Lafayette, La., 59-year-old John Houser opened fire, injuring nine people and killing two before turning the gun on himself.
People go to movie theaters to seek escape from the realities of the world and share an entertaining experience with strangers in a dark room, Americans spend more than $10 billion a year going to the movies and little kids love settling into their theater seat with a big box of popcorn. But Theater shootings have put moviegoer on alert.
We can't stop people from going to the theater to watch movies or drama because of some extreme cases. Actually,Living in fear is not the right solution.
The famous argument of the day according to Howard Levinson of Expert Security Consulting: They cost hundreds of thousands of dollars to install, staff, and supervise, and patrons don’t feel safer when they walk into a movie theater lobby and see them and The cost will be felt by the customer in higher ticket prices.
Nowadays, technology of security products is more advanced, and the security equipment is no longer too expensive to pay .
The cost of a door frame metal detector is between $1,000 and $30,000, and the cost of x ray baggage scanner for theaters is only between$ 5,000 and $10,000. This is not worth a comparison with the cost of the theater and the advanced equipment in the theater.
Securina walk through metal detector detecting speed up to 100 passenger/ min, able to meet high traffic requirement.
Prevention is always better than dealing with emergencies.
Why not put a little bit of cost and avoid a lot of casualties ?
