Ignition sources are materials or conditions that can initiate a fire or explosion. Common ignition sources include open flames, sparks, electrical equipment, and hot surfaces. These sources can ignite flammable materials, leading to dangerous situations in various environments, such as homes, workplaces, and industrial settings. Preventing fires involves identifying and controlling ignition sources. This can be achieved through proper maintenance of electrical systems, safe storage of flammable substances, and implementing fire safety protocols. Awareness of ignition sources is crucial for ensuring safety and minimizing the risk of fire-related incidents in everyday life and specific industries like manufacturing and construction.
