Nonflammable

Nonflammable refers to a substance that is not easily ignited and does not readily propagate flame. Nonflammable materials are often used in applications where safety is a concern, such as in the construction of buildings, the manufacturing of clothing, and the production of various consumer goods.

Definition

The term "nonflammable" is defined by the National Fire Protection Association (NFPA) as a material that does not burn in air when exposed to a temperature of 1500 degrees Fahrenheit (816 degrees Celsius) for a period of five minutes. This definition is used in the United States and many other countries around the world.

Nonflammable materials

Nonflammable materials include substances such as concrete, metal, glass, and certain types of plastic. These materials are often used in the construction of buildings and other structures to reduce the risk of fire. In addition, nonflammable materials are used in the manufacturing of clothing, furniture, and various consumer goods to prevent these items from easily catching fire.

Safety considerations

While nonflammable materials can greatly reduce the risk of fire, they are not completely immune to ignition. For example, if a nonflammable material is exposed to a high enough temperature for a long enough period of time, it can still ignite and burn. Therefore, it is important to always follow safety guidelines when working with or around nonflammable materials.
