At the end of the year and the beginning of the year, several major fires in the country came into shock.
On January 2, 2008, the fire at Dehui International Plaza in Urumqi, Xinjiang continued for nearly 60 hours. More than 2,000 shops were converted to ashes, three fire officers and soldiers committed heroically, and property worth more than 800 million yuan vanished.
On December 12, 2007, a fire broke out at the Mingdian Western Restaurant on Yee An Street, Zhangmutou Town, Dongguan City, Guangdong Province. The accident resulted in 10 deaths and 9 injuries. The fire burned area reached 400 square meters.
On December 12, 2007, an extremely large fire took place in the Wenfu Building in downtown Wenzhou, 21 people were killed in the fire, 2 people were seriously injured, and the fire burned area reached 1,270 square meters. According to the director of Wenzhou City Supervision Bureau, the fire was ignited by a flower shop wire on the ground floor of the building.
Coincidentally, on January 7, 2008, a logistics company in Lichuan City, South Korea’s Gyeonggi Province, exploded and caused a large fire during the installation of polyurethane insulation materials. The fire that lasted several hours produced a large amount of toxic gases, resulting in 40 people. Death, including 12 Chinese citizens.
The tragic loss caused by the fire caused people to turn their attention to the management of flame-retardant products in public places.
The logo became a "key witness"
“In recent years, there has been a large number of serious fires in China. It is necessary and urgent to strengthen the management of flame-retardant products in public places.†The main drafters of “Burning Performance Requirements and Labels for Flame-retardant Products and Components in Public Places†(GB20286-2006), Lu Guojian, deputy director of the Sichuan Research Institute of the Ministry of Public Security's Fire Department, said at a meeting of the China Plastics Processing Industry Association's flame-retardant plastic marking and green plastics promotion working group held not long ago.
Lu Guojian recalled that in recent years, with the rapid development of urban construction in China, new types of building products have been emerging, many public places have adopted a large number of flammable and flammable building products, and the application of electronic and electrical equipment in public places has become increasingly widespread. Fire hazard in public places. Once a fire occurs, it will easily cause the fire to quickly spread and expand, and produce a large amount of toxic smoke, which can easily cause heavy casualties.
It is understood that starting in 2003, the Ministry of Public Security Fire Department began to organize the development of new national standards, and in accordance with the fire safety law and quality law has formulated a management approach, a clear fire retardant products flame retardant identification system. On March 1, 2007, the mandatory national standard "Burning Performance Requirements and Labels for Flame-Retardant Products and Components in Public Places" (GB20286-2006) was formally released. The Fire Protection Bureau of the Ministry of Public Security promulgated the "Measures for the Management of Labeling of Flame Retardant Products" (Trial) . It was also implemented on May 1, 2007.
However, many problems still exist in practice. The problem of identification is one of them.
The Fire Department of the Ministry of Public Security has discovered that because flame-retardant products are not identified, users find it difficult to identify them. At present, there are still a large number of non-flame-retardant products that are flammable, flammable, and prone to produce a large amount of toxic fumes in the event of a fire. At the same time, due to the lack of on-site identification of combustion performance, it is difficult for fire surveillance personnel to discover and supervise rectification in a timely manner. Therefore, the implementation of flame-retardant product identification management work is imperative. Lu Guojian stated: “The flame-retardant signs are clearly indicated to the public and are conducive to protecting the legitimate rights and interests of enterprises and consumers. At the same time, they are also convenient for the daily supervision of the fire department and will strongly promote the standardized application of flame-retardant products, thereby reducing the risk of fire in public places. Sexuality is of great practical significance to curb heavy fire accidents in public places."
Gao Wei, director of the Department of Fire Protection Science and Technology of the Ministry of Public Security, said that the use of flame-retardant products to replace traditional flammable and combustible products to improve the ability to prevent and resist fire in public places is an internationally accepted practice. In recent years, the International Organization for Standardization (ISO), the European Organization for Standardization (EN), the United States Underwriters Laboratories (UL) and the American Fire Protection Association (NFPA) have all issued many standards concerning flame-retardant performance testing and evaluation. Japan, The United States and other developed countries have also promoted the use of flame-retardant products with flame-retardant signs in public places and achieved successful experiences.
Flame-retardant plastic can bear heavy duty
On December 7, 2007, the Fire Bureau of the Ministry of Public Security promulgated the “Notice on Further Strengthening the Management of Flame-Retardant Products in Public Places†(public notification [2007] No. 503), requiring relevant units at all levels to strictly implement the mandatory national standards. GB20286-2006, stipulates that from July 1, 2008, all public places that use flame-retardant products that do not meet the requirements of GB 20286-2006, fire protection inspection or pre-opening fire safety inspection shall not be passed.
In other words, starting from July 1 this year, all flame-retardant building products, flame-retardant fabrics, flame-retardant plastics/rubber, flame-retardant foamed plastics, flame-retardant furniture, etc. which cannot meet the flame retardant standards of GB20286-2006 Components, fire-retardant wire and cable products will not be used in public places. There are five categories related to plastics in these six categories.
According to Ou Yuxiang, chairman of the China Flame Retardant Society, flame-retardant plastics are promising in reducing fire hazards. Speaking of the contribution of flame-retardant plastics to reducing the danger of fire, Eu Yu-hsiang believed that the most convincing evidence is the results of the original National Bureau of Standards (NBS, now renamed the National Institute of Technology and Standards, NITS) in 1987. NBS compared the fire hazard of flame-retardant and end-fire-retardant specimens of five typical plastic products: high-impact polystyrene TV housing, modified polyphenylene ether computer housing, polyurethane foam plastic chair, with Polyethylene insulation and rubber sheathed cable, unsaturated polyester fiberglass circuit board. The test results show that compared with the end-fire-retardant specimens, the fire-retardant specimens after the fire not only have a lower mass loss rate, a slower heat release rate, and a lower toxic gas content, but also provide a longer time for evacuation and rescue of property. .
In order to prevent and reduce the occurrence of fire, various countries are promoting the application of flame-retardant plastics. In the decades of the second half of the 20th century, some countries have achieved remarkable results in this regard. Taking the United States as an example, due to the implementation of fire-retardant furniture and other fire prevention measures, the number of fire deaths has dropped significantly. U.S. and British TV manufacturers used flame-retardant plastics to manufacture TV enclosures and certain components in the 1970s and 1980s, respectively, causing TV fires to decline year after year.
In the opposite case, the number of television fires in some countries in Europe has more than doubled between 1990 and 1995 due to the reduction in the fire-retardant rating of the TV housing and some TV component plastics.
Plastic Corporate Social Responsibility
“It's hard to imagine that there is no plastic product in a room at the moment. It is the popularity of this application that makes today's health, environmental protection, and fire safety highly valued. Plastic fire retardant is particularly prominent and important. As an industry organization, we have an unshirkable responsibility.†Liao Authentic, chairman of the China Plastics Processing Industry Association, and the leader of the China Plastics Association fire-retardant plastic marking and green plastics promotion working group, made clear in an interview.
In order to cooperate with the deployment of the Fire Bureau of the Ministry of Public Security, China Plastics Processing Industry Association established the "flame-retardant plastic product identification and green plastics promotion working group" in December last year. According to the briefing, the working group is an office established to implement the notification spirit of flame-retardant product labeling management measures of the Ministry of Public Security and the relevant policies for flame-retardant plastic products and the mandatory national standard GB20286-2006. It is dedicated to advancing the plastics industry. The fire retardant performance fully meets the requirements of the Ministry of Public Security Fire Department. The working group will also participate in the revision of relevant laws and regulations, promote energy-saving and emission-reduction technologies, and fulfill the social responsibility of the plastic flame-retardant products industry. The task force will focus on five categories of plastic-related flame-retardant building products, fire-retardant plastics/rubber, flame-retardant foams, fire-retardant furniture and components, and fire-retardant wires and cables, as stipulated in the compulsory national standard GB20286-2006. , In the fire retardant performance to fully meet the relevant standards, and actively carry out flame retardant identification in plastic products on the application and promotion.
Liao also mentioned that the concept of flame retardancy in the new national standard GB20286-2006 is very different from the traditional concept and is a new concept with richer content. In the past, the flame retardant often only required that the material was not easily ignited by a small fire source. The new standard not only requires that the material is not easily ignited by a small fire source, but also requires that the material or component have the lowest possible heat release rate, and at the same time requires the production of smoke. Small amount, low smoke toxicity. At present, many domestic companies cannot meet the requirements of the new standard. Therefore, he appealed that companies engaged in the production of fire-retardant plastic products should take active actions to effectively handle acceptance, use and promotion of fire-retardant labels, and fulfill their social responsibilities in the flame-retardant plastic products industry to better serve the industry. , Corporate services; The use of flame-retardant plastic products and fire safety and advanced design technology to build a reliable fire protection system, and strive to create a new situation of flame-retardant plastic products in public places, and contribute to the passive fire safety of public places in China.
