Which personal factor can increase the risk of electrical accidents in explosive environments?

Fatigue is a significant personal factor that can increase the risk of electrical accidents in explosive environments because it impairs an individual's ability to function effectively. When a person is fatigued, their attention, reaction times, and overall cognitive performance can diminish. This reduction in alertness may lead to oversights or errors in judgment, particularly when handling potentially dangerous equipment or materials.

In environments where explosives are present, even a small lapse in concentration due to fatigue can have dire consequences, such as improper handling of electrical systems, failure to follow safety protocols, or not recognizing hazards promptly. Maintaining optimal physical and mental conditions is crucial for ensuring safety and preventing accidents in such high-risk settings.
