Fire blanket
A fire blanket (also fire blanket ) is a small extinguisher and is mainly used for quenching of incipient fires.
The main effect of extinguishing a fire blanket, suffocation, caused by the separation of oxygen and combustible material.
Fire blankets are made from flame retardant treated wool, also made of fiberglass or Nomex, formerly mainly from asbestos.
Suitability
A fire blanket can be used as an extinguishing agent in incipient fires. According to recent findings (. Among operating conditions, such as in restaurants, bakeries and the like in the face of large amounts of oil and edible fat, for example, in Fritösen ) are fire blankets to extinguish grease fires - that they were often held in the past in kitchens - only limited suitability:
The German BGN ( BG food and restaurants ) has conducted experiments to delete grease fires. It was found that the fire blankets (wool, cotton, glass, Nomex and Kevlar ) are only partially suitable for extinguishing grease fires, as they can burn out at too high " heat potential " Probably condensed the hot grease vapors and thus ensure an inflammation the ceiling ( wicking ). In these experiments it was also found that other, often for grease fires proposed in the past, extinguishing agents, such as chemical or carbon dioxide, are only partially or not at all suitable.
As these results to the private household ( handle with smaller pans or woks ) can be transmitted, should be examined. A fire extinguisher is particularly suitable for grease fires, is certainly the best solution - a fire blanket can within the home may be sufficient for initial fires.
Standardization
While it was formerly known as fire blanket, the standardized German -language name according to EN 1869 only fire blanket. In practice, the old name but is often used.
The DIN 14155, after it was standardized in Germany is no longer valid for fire blankets. The same applies to the ÖNORM F 1010, after she was standardized in Austria.
For the marking of a place where a fire blanket is available in Germany is a symbol that is in force in accordance with BGV A8 and DIN 4844 are provided. In Austria there is no standard for this. The reference can also be done with text panels.
