What is the closest distance you can approach the disconnect for the infrared survey described?

• A. 50 ft
• B. 150 ft
• C. 100 ft
• D. 200 ft

Answer: (C)

Maintaining a safe standoff from energized disconnects during an infrared survey is essential to protect you from arc flash and shock risks while still allowing you to get a clear, usable thermal image. In the described survey, 100 ft is designated as the minimum safe distance. This distance provides enough clearance to reduce exposure risk and give you room to maneuver or retreat if something changes, while still letting you use a suitable lens to capture accurate thermal data. Being closer, such as 50 ft, would increase safety risk, whereas going much farther—like 150 ft or 200 ft—would make it harder to obtain a quality image and would not align with the survey protocol’s stated minimum. So, 100 ft is the appropriate closest distance.
