Classification of Fires
2026-08-25
A fire is a disaster caused by combustion that has become uncontrolled in time or space. Under the new standard, a fire is defined as combustion that has lost control in either time or space. Among all types of disasters, fires are one of the most frequent and widespread hazards, posing a major threat to public safety and social development.
Fires can be classified into six categories: A, B, C, D, E, and F.
1. Class A fires: Fires involving solid materials. These materials are typically organic in nature and generally produce glowing embers when burning.
2. Class B fires: Fires involving flammable liquids or solid materials that can melt.
3. Class C fires: gas fires.
4. Class D fires: metal fires.
5. Class E fires: Electrical fires—fires involving energized electrical equipment.
6. Class F fires: Fires involving cooking oils and fats in cooking equipment, such as vegetable or animal oils.
Humanity’s ability to harness and control fire through tools such as fire extinguishers is a key hallmark of civilizational progress. Therefore, while using fire, we must continually analyze the patterns underlying fire incidents in order to minimize fires and the harm they inflict on humankind.
