介绍
LED显示屏, the visual highlight of modern performances, make the stage more dazzling. But do you know? The safety issues behind them are also worthy of attention.
The heart-wrenching concert accident at the Hong Kong Hung Hom Coliseum is a wake-up call. Today, let’s talk about how to ensure the safety of LED display screens during installation so that every performance is safe and wonderful.
1. The importance of the safety of LED display screens
LED display screens, whether it is the dazzling advertisements in shopping malls or the shocking background of concerts, play an indispensable role.
But when installing these high-tech “stars”, safety hazards are like shadows hidden behind them and cannot be ignored. So why is it so important to pay attention to safety hazards when installing LED display screens?
1). Ensure the “longevity” of the display screen
Imagine that if the display screen is shaky in the wind and rain or “strikes” from time to time due to negligence during installation, it will be a headache.
Pay attention to safety hazards and ensure that every step of the installation is steady and steady so that the display screen can run stably in the future and reduce the trouble of maintenance and replacement.
2). Protect the safety of “Spider-Man”
Installing LED display screens often requires high-altitude work, which is not easier than “Spider-Man” in the movie.
If safety measures are not in place, the installers may face life-threatening dangers. Paying attention to safety hazards and providing them with a safe working environment is respect and protection for their lives.
3). Maintaining the tranquility of public places
LED display screens are mostly installed in public places, where people come and go and are very lively. If the display screen falls or electrical failure occurs due to improper installation, the consequences will be disastrous.
Paying attention to safety hazards is to maintain the tranquility of public places so that everyone can enjoy the convenience brought by technology with peace of mind.
4). Add points to the industry and set a good example
The LED display industry is booming, but frequent safety accidents will seriously affect the reputation of the industry.
Paying attention to safety hazards and improving installation quality can not only make your own brand more famous, but also set a good example for the entire industry and promote the entire industry to a safer and more professional direction.
Therefore, when installing LED display screens, don’t let safety hazards become “invisible killers.” Paying attention to it means paying attention to safety and everyone’s life and happiness.
2. Review of the LED display screen accident at the Hong Kong Coliseum Concert
1). Accident background
时间地点： Hong Kong Coliseum on the evening of July 28, 2022.
Event overview: At the climax of the MIRROR boy band concert, a giant LED display screen weighing about 500 kilograms and hanging at a height of 7 meters suddenly fell, causing serious injuries to two dancers.
Display screen details: 4 meters × 4 meters in size, 0.2 meters thick, suspended by two steel cables.
2). Accident process
- Fall moment:
During the concert, one side of the steel cable broke due to the heavy load, and the display screen tilted; then, the other side of the steel cable also broke, and the display screen smashed onto the stage like a boulder, hitting and crushing two dancers.
- 紧急救援：
The on-site staff immediately stopped the performance and launched emergency rescue, and the injured were quickly sent to the hospital. The police and fire departments quickly intervened, controlled the scene, and launched an investigation.
3). Analysis of the cause of the accident
3.1). Preliminary cause:
Metal fatigue of the steel cable: Laboratory test results showed that the steel cable caused metal fatigue due to long-term heavy pressure.
Weight overload: The actual weight of the display far exceeds the designed load-bearing capacity, which increases the burden on the hanging system.
In-depth investigation: A cross-departmental working group was set up, including the Electrical and Mechanical Services Department, the Labour Department, etc., to conduct a comprehensive investigation of the accident and finally confirm that multiple factors worked together to cause the accident.
This accident is not only a wake-up call for stage safety but also reminds us that no matter how advanced the technology is, safety always comes first.
3. What are the safety measures for LED display installation?
When installing LED displays, a series of safety measures must be taken to ensure personnel safety, equipment stability, and environmental protection. The following is a detailed explanation of these measures:
1). Select LED products that meet standards
- 重要性：
Selecting products that have been professionally tested and meet national standards is the first step to ensure safety. These products usually undergo strict quality control and performance testing to ensure stable performance and safety in long-term use.
2). Reasonable selection of installation location
- Light and 亮度:
The choice of installation location has a direct impact on light intensity and brightness. Avoid installing the display in direct sunlight or in an overly dark environment to ensure display effect and audience comfort.
- Environmental requirements:
Avoid installing the display screen in a humid, dark environment and near flammable and explosive items to reduce safety hazards.
At the same time, the ventilation and heat dissipation conditions of the display screen should be considered to avoid overheating and equipment damage or fire risks.
3). Ensure that the installation is firm and reliable
- Firmness:
During the installation process, the firmness and reliability of the display screen should be ensured. Use high-quality fixings and connectors to ensure that the display screen can be stably hung in the designated position.
- Additional requirements:
For outdoor LED display screens, additional requirements such as waterproofing and lightning protection should also be considered.
Use waterproof materials and lightning protection devices to ensure that the display screen can still operate normally under severe weather conditions.
- Electrical wiring:
The electrical wiring should be correct to avoid problems such as short circuits and underpowered wires. Use wires and plugs that meet safety standards to ensure the safety and reliability of electrical connections.
4). Use accessories that meet safety specifications
- Accessory safety:
Accessories such as electrical plugs, junction boxes, and metal fixings should comply with safety specifications to ensure that no safety hazards are caused during use.
- Correct use of accessories:
Follow the product instructions and use accessories correctly. Avoid using unqualified or damaged accessories to avoid safety accidents.
5). Avoid environmental problems
- Environmental problems:
The production and use of LED display screens may bring environmental problems, such as waste disposal and energy consumption.
- Environmental protection measures:
During the installation process, environmental protection measures should be taken, such as using environmentally friendly materials and reducing waste generation.
At the same time, attention should be paid to the energy efficiency performance of the display screen, and energy-efficient products should be selected to reduce energy consumption.
6). Pay close attention to the operating status
- Operation status:
After installation, you need to pay close attention to the operating status of the display screen to promptly discover and deal with possible problems.
- 定期检查：
Regularly maintain and inspect the display screen, including cleaning, tightening screws, checking electrical connections, etc. Ensure that the display screen maintains stable performance and safety during long-term use.
7). Pay attention to live operations and public security precautions
- Live operation:
When performing live operation, you should strictly abide by the safety operating procedures to ensure the safety of the operator. Especially when installing outdoors, special attention should be paid to anti-electric shock and anti-short circuit measures.
- Public security precautions:
In order to prevent safety issues such as theft of personnel and accessories, public security precautions should be taken. Such as installing surveillance cameras, strengthening patrols, etc., to ensure the safety of the display screen and its accessories.
结论
In the final analysis, the safety of LED display screens is not only a technical issue, but also a responsibility to every audience and every performer.
By strictly abiding by the standards, selecting high-quality products, and carefully installing and maintaining, coupled with the joint efforts of the industry, we are fully capable of avoiding those heartbreaking accidents.
