What is the minimum hot zone circle that should be maintained from transmission lines?

Maintaining a minimum hot zone circle of 100 feet from transmission lines is critical for safety during fire response and emergency situations. This distance helps ensure that responders are protected from electrical hazards, especially in instances of downed power lines or active electrical equipment. The 100-foot distance allows for adequate space to avoid potential electrocution or arc flash injuries that can occur from proximity to high-voltage lines.

By establishing this zone, fire personnel can safely operate and provide assistance without increasing their risk exposure to electrical hazards. Additionally, the 100-foot radius allows for the safe management of any potential ignition sources, provides a buffer from falling debris associated with electrical failures, and facilitates easier evacuation of civilians if necessary. This practice aligns with safety protocols recommended by various fire service and electrical safety standards, ensuring that first responders operate within a safe environment while managing emergencies near high-voltage infrastructure.
