How can broken glass cause a fire?

Broken glass can cause a fire by acting as a lens, focusing sunlight onto flammable materials. When sunlight passes through the curved or sharp edges of the glass, it can create intense heat at a specific point, potentially igniting nearby combustible items like paper, dry grass, or fabric. Additionally, if broken glass is found near electrical equipment or wiring, it can lead to shorts or sparks, further increasing the risk of fire.
