What materials are considered combustible in fire safety terms?

In fire safety terms, combustible materials are defined as those that can easily burn. This includes various organic materials such as wood, paper, and cloth, as well as many synthetic materials. The key characteristic of combustible materials is their ability to ignite and support fire under certain conditions. Recognizing these materials is crucial for fire safety management, particularly in shelters where flammable substances must be controlled to prevent fire hazards.

The other options do not accurately describe combustible materials. Focusing solely on plastics fails to encompass the wide range of other combustible materials that also pose fire risks. On the contrary, materials that do not burn at all and completely fireproof materials are, by definition, non-combustible and do not fit into the category of combustible materials. Understanding this distinction is vital for effectively managing fire safety in any setting.
