What is the minimum safe distance for fog streams greater than 30 degrees on live 345kv components?

The minimum safe distance for fog streams greater than 30 degrees on live 345kV components is set at 125 feet. This distance is critical for ensuring safety when dealing with high-voltage electrical systems. At 345kV, the electrical components are under significant voltage, which increases the risk of arc flash or electrical shock if a firefighter gets too close while using water streams.

A fog stream can create a fine mist that might not provide the same risk as a solid stream, but it can still carry the potential for electrical conductivity if it gets too close to energized components. The 125-foot guideline is based on the need to maintain a safe operational distance to prevent accidental contact or hazardous conditions that could arise from stray electrical arcing or unintended interactions between water and high-voltage electricity.

Other distances may not provide adequate safety margins when working with such high-voltage systems, emphasizing the importance of adhering to safety protocols and standards in firefighting practices around electrical hazards.
