Shorts and sparks from defective electrical cables and equipment can start a fire.

Explanation:
Electrical faults are ignition sources in a mining environment. When cables or equipment short, the current can overheat the conductors or insulation, and arcing can produce a spark. Those sparks and the heat can ignite flammable materials that may be present, such as methane gas or coal dust. In surface coal operations, methane and fine coal dust are common ignition hazards, so a defective electrical cable or equipment can indeed start a fire. This is why electrical systems are kept in good condition, properly protected, and tested regularly to prevent such ignition sources.
