Neon overdue service
On the evening of July 4th, a fire broke out in the “Progressive Studios†in Hengyang City, Hunan Province. All the first to fifth floors of the cinema caught fire, causing one death. The cause of the fire was initially found to be caused by the spontaneous combustion of large neon lights hanging outside the cinema.
On July 10, the reporter found dozens of outdoor neon advertisements on Wusi Road and Wuyi Road in Fuzhou, and found that Fuzhou outdoor neon lights generally have a super-year use situation.
City Fire Brigade Propaganda Section Chief Wen said that the use of expired wires or tubes in the summer is equivalent to burying "fire."
Phenomenon May Fourth Road neon lights generally aging
At night, walking in the bustling streets of Fuzhou, the flashing neon lights are fascinating, but the reporters found that these neon lights generally have "excessive service" phenomenon.
Yesterday morning, the reporter conducted a survey on the neon lights of the May Fourth Road and the Provincial Sports Center. A security guard at the Galaxy Garden Property Office said that the outdoor neon lights of a sauna in the building have never been replaced in the past four years, and the u-shaped lamps used in the neon lights have a service life of only three years.
Ms. Peng, from the Huihui Guest House, said that since the opening of the guest house in 2002, neon signs have never been updated.
Deputy General Manager of Huangpu Seafood Restaurant of Provincial Sports Center said that the neon signboard of the restaurant has never been replaced since its opening in 2004. As for the service life of the lamp, they know nothing about it. "We feel that as long as the lights are not broken, there is no need to change them."
The reporter then investigated a number of neon signs, such as the Provincial Medicine Group and Huaxiang Building, and found that the lamps with a service life of only 3 years have been working for more than 3 years.
Hidden dangers are very easy to catch fire under neon exposure
What are the consequences of neon "overdue service"?
According to Mr. Yin from Fuzhou Longxin Electric Light Source Factory, the materials for making the lamp tube mainly include soda glass tube and lead glass tube. The stability of the sodium glass tube is very good, it is easy to deteriorate after damp, the difference in fastness is easy to burst, and the current usage is about 80%; the heat resistance and service life of the lead glass tube greatly exceeds that of the soda glass tube, but the usage is only about 80%.
According to reports, outdoor advertising neon lights are mainly wired tubes, u-tubes, soft plastic packaging tubes and t4, t5 tubes, and the service life of linear tubes and soft plastic packaging tubes is generally only 1 year, and other lamps have a service life of 2 -3 years. The linear tube and the soft plastic packaging tube have plastic foreskin on the outer layer of the circuit. Under the exposure, the layer of the sheath is prone to aging. If it is not replaced in time, the line is easily ignited when shorted.
Ouyang, a lighting engineer at Southeast TV, said that in order to save costs, some people use ink water instead of fire retardant paint when making neon signboards, which are sprayed on the bottom of the lamp to achieve a reflective effect, while the ink water itself contains charcoal components, when the lamp is broken or short-circuited. It is easy to be ignited.
Manage neon safety maintenance by conscious
The safety hazard of neon lights is not known to the user. At present, the installation of outdoor neon lights is mainly handled by the industrial and commercial departments. After the initial approval, the “Outdoor Advertising Review Contact Form†will be issued to the relevant departments of city appearance, planning, traffic police, municipal administration and electric power.
A person in charge of the Outdoor Advertising Management Association told the reporter that after the neon signboard was installed, the advertiser was responsible for daily security maintenance, but many advertisers rarely carried out regular security checks to save maintenance costs.
Fuzhou City Fire Brigade Propaganda Section Chief said that the summer is hot and dry, the outdoor line is not well maintained, it is easy to cause fire, advertisers should regularly check whether the line is aging, replace the expired lamp.
Wen Kechang introduced that in the event of a fire in the circuit, the public should first cut off the power supply and then use a fire extinguisher to save the electricity to avoid electric shock.
Fuzhou Cinema
Unexplained fire hazard
After the Hengyang Studios fire broke out, Fuzhou citizens were most concerned about whether there were fire hazards in the cinemas in Fuzhou.
Yesterday, the reporter visited the Fuzhou Grand Theatre, the popular theater, the glorious drama and the star movie studio. It was found that in addition to the long-term theater buildings, fire-fighting passages and fire-fighting equipment were set up inside and outside the theater, and there were no major fire hazards.
Ms. Lin of Fuzhou Grand Theatre said that the hospital has gradually changed to a small package hall of about 100 people, and has strict fire compartments and fire exits. In addition to the irregular inspections by the fire department, the electrician masters regularly maintain them every month. A fire hazard caused by a short circuit.
