How far can vaporized droplets of molten metal be propelled during an arc blast?

• A. 5 feet
• B. 10 feet
• C. 20 feet
• D. 30 feet

Answer: (B)

Vaporized droplets of molten metal can be propelled quite a distance during an arc blast due to the intense energy and heat generated by the electrical fault. In this scenario, the phenomenon of an arc blast can lead to rapid vaporization of conductive materials, resulting in high-velocity ejection of molten particles. The distance these droplets can travel is influenced by the force of the explosion and the physical properties of the materials involved. In practical terms, research and incident reports suggest that molten metal droplets propelled during an arc flash can indeed reach up to approximately 10 feet. This distance significantly highlights the hazards associated with electrical work and underscores the importance of protective measures and appropriate safety gear. Familiarizing oneself with these distances is crucial for anyone working in environments where electrical systems are present, ensuring that proper clearance and protective barriers are established to mitigate the risks.
