The risk of ignition can increase due to which of these factors?

The risk of ignition can indeed increase significantly due to overloading electrical components. When electrical components are overloaded, they may exceed their rated capacity, causing excessive heat generation. This heat can ignite flammable materials or create sparks, leading to potential explosions or fires in hazardous locations where flammable gases, vapors, or dust are present.

In contrast, clear environmental conditions, while they may allow for better visibility and operation, do not inherently increase the risk of ignition. Circuit protection devices are specifically designed to prevent overloads, short circuits, and faults, thus reducing the risk of ignition rather than increasing it. Proper grounding techniques help dissipate electrical energy safely and mitigate the risk of ignition by preventing static buildup and providing a path for stray currents, further lowering the risk in hazardous environments.
