How is 'combustion' defined in fire-related terms?

The term 'combustion' in fire-related discussions refers specifically to the rapid oxidation of flammable material. This process occurs when a fuel reacts with an oxidizing agent, typically oxygen, at a high temperature, resulting in the release of heat and light. This rapid reaction is what differentiates combustion from other forms of oxidation, such as rusting or corrosion, which occur much more slowly. Understanding this definition is crucial for fire safety, as it highlights the conditions necessary for fires to start and the importance of controlling flammable materials and oxygen in fire prevention strategies.
