Flame retardant materials in plane crash accident security firewall
"In July 6, asiana airlines flight 214 crash, the vast majority of passengers are safely evacuated, flame retardant materials." Before this is aviation experts at home and abroad experts express agreement with flame retardant material.
Asiana airlines plane crash accident happens, the New York times, the Wall Street journal, the Los Angeles times several us media reports on it, such as repeatedly mentioned, flame retardant materials are widely used in the body, is the most important reason to avoid more casualties.
The flight safety foundation, chairman and CEO Kevin seat said, the use of flame retardant materials in the accident. In the accident, the flame temperature is too high, even lit the plane of the metal, also lit up the inside of the hull after other items. But in the end, still have enough time to escape (about 3 to 5 minutes), most of the passengers are successful escape, thanks to a large amount of flame retardant materials used on the plane. New flame retardant material makes the module internal lit more slowly, and avoids the release harmful gases, and both of which is an important factor to ensure the safety of disaster field personnel evacuation.
The accident, the Boeing 777 aircraft landing hit on the right side of the engine, fuel tank leakage quickly caught fire. Burn in the fire to the front of the hull, almost all the passengers were safe escape, even in an emergency after rescuers remove injured passengers into the engine room, the fire is not spread. On the Boeing 777 jet from the fuselage to tank top and seat, almost every place using various types of flame retardant materials, to ensure that the passengers have plenty of time to escape. This fully shows that flame retardant materials can effectively reduce the fire spreading, provide valuable time to escape. The flame retardant association of North America (NAFRA) experts said after the accident, if the plane is not application of flame retardant materials, there will be more people injured or killed in the incident.
Secretary general of China flame retardant society Zhou Zhengmao says, in order to reduce aircraft weight, save fuel, the plane of the light of the high polymer material, at the same time of trouble is to increase the flammability of the plane. Thirty years ago, on the international regulations on the plane using polymer materials such as plastics, textiles and so on must be flame retardant materials. This regulation has achieved significant results. The national transportation safety board data show that from 1962 to 1962, the United States in the crash, with 54% of passengers were killed; From 1982 to 1982, reduced to 39% of the data.
At present, with the improvement of national fire safety regulations, standards, flame retardants in plastics, textile and other kinds of the application of polymer materials is more and more widely, especially in the plane, automobile, electrical and electronic products become an indispensable security barrier. In recent years in our country also strengthen the generalization and application of flame retardant products constantly, related departments also have issued the relevant fire safety laws and regulations, improve the flame retardant grade of all kinds of flame retardant products. But, because of increased regulation and cost factors, the application of flame retardant materials in both quantity and quality in China has a certain gap compared with developed countries, on the potential fire hazard should not be ignored.
"To alert the asiana crash to us again, further intensify supervision, strengthen the promotion and popularization of the flame retardant materials is to reduce the fire hazard and fire of the important means of casualties and property losses, both on the planes, cars and other vehicles, or in a public place or in the family, the organic material of the flame retardant fire can't ignore." Zhou Zhengmao said.
