When working with high voltage, employees must be particularly aware of flames and electric arcs as significant hazards. High voltage systems can generate electric arcs, which can occur when there is a breakdown in insulation or contact between conductors. These arcs can be extremely dangerous, leading to severe injuries or even fatalities. Additionally, the presence of flames can occur in scenarios where electrical faults igniting combustible materials or from arcing can lead to fire hazards.

Understanding the risks associated with flames and electric arcs is vital for ensuring proper safety precautions are taken, such as using appropriate personal protective equipment (PPE) and following safety protocols, which are critical for minimizing the risk of accidents in high voltage environments.

While other options reference hazards that may be present in various work environments or under different circumstances, the specific dangers posed by electric arcs and flames are closely tied to the handling of high voltage systems. This knowledge empowers employees to maintain safety and mitigate risks effectively while working in these potentially perilous situations.
