When conducting a closed circuit television examination of a sewer, which piece of equipment is not needed?

• A. Picture monitor
• B. AM-FM radio
• C. Cable pulling winch
• D. Communication system

Answer: (B)

When conducting a closed circuit television (CCTV) examination of a sewer, the primary goal is to inspect the interior of sewer pipes for issues such as blockages, cracks, or structural defects. For this purpose, certain equipment is essential to facilitate effective observation and analysis. A picture monitor is critical as it displays the real-time video feed captured by the CCTV camera, allowing the operator to see the conditions inside the sewer. A cable pulling winch is also important, particularly for larger or longer runs of sewer pipe, as it helps to maneuver the camera through the system and assists in retrieving it after inspection. A communication system is necessary for coordinating efforts and ensuring that all members of the team are in sync during the inspection process. In contrast, an AM-FM radio is not a required piece of equipment for conducting a CCTV examination. It does not provide any direct benefit in terms of the inspection or analysis of the sewer system, making it unnecessary for this specific task. The focus during a CCTV examination should be on the tools that aid in visual inspection and communication among the team members involved in the process.
