Firecrackers are typically made using a Crackers produce sparks and flames upon ignition, which can easily start fires if they come into contact with flammable materials like clothing, curtains, or dry leaves.

Firecrackers produce sparks and flames upon ignition due to the rapid combustion of their pyrotechnic composition. When ignited, the black powder inside the firecracker undergoes a chemical reaction, releasing energy in the form of heat, light, and sound. These sparks and flames can ignite nearby flammable materials such as clothing, curtains, or dry leaves, posing a fire hazard. Therefore, it's essential to handle firecrackers with caution and ensure they are used in safe environments away from combustible materials.

Firecrackers are designed for entertainment but can be hazardous if mishandled. The chemical reaction within them not only creates the visual spectacle but also generates significant heat. This heat, combined with the release of gases and pressure, causes the explosion and subsequent emission of sparks and flames. These elements can spread rapidly, especially in dry or windy conditions, increasing the risk of fires. To mitigate this risk, it's crucial to follow safety guidelines, such as keeping firecrackers away from combustible materials, using them outdoors in designated areas, and never attempting to modify or relight malfunctioning ones. Additionally, proper disposal after use is essential to prevent accidental ignition. Practicing responsible firecracker use ensures a safer environment for everyone during celebrations and festivities.
