Another Fire Accident Occurred On The Rental LED Display, Regrettable!

On July 16, the main stage of the world's largest Tomorrowland music festival was covered in smoke that could be seen from miles away. Part of the main stage had been burned and could not be used. It was reported that the festival was originally scheduled to open in the Belgian town of Boom this Friday (tomorrow), but a fire broke out on Wednesday. The burned main stage took two years to complete, was 160 meters wide and 45 meters high, equipped with 1,000 square meters of screens and fountains, 1,500 spotlights... It is estimated that the property loss will be 10 million yuan. It was originally expected that a total of 100,000 festival participants would be welcomed this weekend.

 

 

As of now, the cause of the fire is unknown, but organizers have confirmed that the festival will go on without the main stage.

 

As concerts and music festivals continue to be held around the world, stage construction safety is very important. Excluding other factors causing fires, the main causes of fires on stage LED displays are currently as follows:

 

1. Electrical safety hazards

Circuit design issues: Rental LED display circuits are complex, including power lines, signal lines, control lines and other lines. If the circuit design is unreasonable, such as chaotic line layout, small wiring spacing, etc., it is easy to cause electrical faults such as short circuits and overloads, which can cause fires. · Power supply issues: Poor power quality, such as using inferior raw materials and no overvoltage protection function, may cause the voltage to rise instantly and burn out the IC. If the power cord terminals are inferior products or have poor contact, they will also cause heating and sparks, which will become a fire hazard.

 

2. Heat dissipation problem · Unreasonable design of heat dissipation system

LED display screens generate a lot of heat when working. If the heat dissipation duct is not designed properly, dust will accumulate on the fan shaft, power supply and motherboard, resulting in poor heat dissipation, short circuit of electronic components and fan jam, which will cause fire. · Insufficient or faulty heat dissipation equipment: In a high temperature environment, if there is no exhaust fan, air conditioner or other heat dissipation equipment with sufficient power, or the heat dissipation equipment fails and cannot dissipate heat in time, the internal temperature of the LED video Wall will be too high, increasing the risk of fire.

 

3. Material selection issues · Frames, back panels and other parts are flammable

The frames, back panels and other parts of Rental Display Video Wall are made of flammable materials. Once they encounter a fire source, the fire will spread rapidly. · Aging of protective materials: If ordinary aluminum-plastic panels are used for outdoor displays, they will age quickly due to high temperatures, rain, cold and heat shocks. In humid climate seasons, rain and dew can easily penetrate into the screen, causing short circuits in electronic components and causing fires.

 

4. Problems with wires and plastic kits · Poor wire quality

The quality of wires on the market varies. Some wires have copper-clad aluminum spools, which look like copper wires, but are actually aluminum alloy wires and cannot be used in regular products. In addition, copper wires may have problems with copper quality, insulation layer, wire diameter, etc. If any one of them is neglected, it may pose a fire hazard. · Plastic kits do not meet standards: If the plastic kits purchased are inferior products made of recycled materials, they are not UV-resistant and have no flame retardants. Long-term use may cause rainwater to penetrate into the wires and cause short circuits.

 

 

5. Installation and maintenance issues ·Improper installation

During the construction process, the use of substandard cables, wires that are not compressed tightly, resulting in poor contact and heat generation, and unreasonable configuration of the distribution box, etc., are all safety hazards for Event LED Screen Rental in the future. Improper welding operations, the use of open flames or smoking during the installation and debugging of the display screen are more likely to cause a fire on the spot. ·Inadequate maintenance: Hire LED Video Wall is not regularly tested and inspected, and problems such as line aging and damage, power supply and control system failures, and cooling system abnormalities cannot be discovered and handled in a timely manner, resulting in the accumulation of hidden dangers and eventually causing a fire.

 

 

So, how to avoid fire on stage rental LED Display?

 

1. Procurement and installation stage

Select qualified products: Purchase Large LED Screen Rental products that have passed relevant certifications, are of reliable quality, and have good fireproof performance. For example, choose a UL-certified power supply with a high conversion rate, which can ensure the safety and stability of the power supply load.

 

Use high-quality wires: Select wires that meet national standards, with copper wire conductive carriers as the core, the cross-sectional area tolerance of the core within the standard range, and the insulation and flame retardancy of the rubber wrapping the core meet the standards.

 

Use flame-retardant materials: The external protective structure of Large LED Video Screens should use materials with higher fireproof grades such as fireproof aluminum-plastic panels, and the plastic kit should use PC+glass fiber materials with flame-retardant functions.

 

Standardized installation and construction: Installation by professional technicians to ensure that the support structure of Stage Rental LED Screen is firm and meets relevant safety standards. Clear the flammable and combustible materials around the display screen to prevent fire hazards in the surrounding area from causing fire.

 

2. Operation and maintenance stage

 

Strengthen heat dissipation management: Rationally design the heat dissipation duct, configure heat dissipation equipment such as exhaust fans and air conditioners, and ensure that the temperature inside the screen remains normal and constant.

 

Regular inspection and maintenance: Professional technicians regularly test and inspect the Stage Rental LED Screen, including checking whether the wire connection is firm, whether it is aging or damaged, whether the power supply is working properly, whether there is dust accumulation inside the display screen, etc., to promptly discover and deal with potential safety hazards.

 

Set up safety devices: Install temperature, smoke and other detection and alarm devices in the display screen, connect the computer system that controls Event LED Display, realize automatic inspection, display and storage of temperature, humidity and fire information, and alarm when the set value upper limit is reached, and automatically cut off the power supply when there is a fire hazard.

 

Standardize operating behavior: When installing and debugging Stage Background LED Screen, it is strictly forbidden to use open flames or smoke, and avoid behaviors such as irregular welding operations.

 

Summary: For a long time, the use of Concert Video Display has been very large and frequent, and there are not a few safety accidents, so the industry must strengthen prevention. Especially now that concerts and music festivals are being held intensively around the world, relevant units must take this as a warning, and in addition to ensuring the quality of Stage Background LED Display Big Screen, they must also strengthen knowledge training in installation and maintenance, and let qualified professionals take up their posts to ensure that nothing goes wrong.
