Tennessee Wastewater Operator Practice Exam

If a communicator is not operating properly, which is the first step an operator should take?

1. Cut off the electricity

2. Check the motor and look for blockage

3. Lock out and tag the breaker

4. Place the bar screen into service

The first step an operator should take when a communicator is not operating properly is to check the motor and look for blockage. This is crucial because identifying any immediate mechanical issues or blockages can quickly determine the cause of the malfunction. Blockages, whether from debris or other obstructions, can prevent the communicator from functioning correctly, so inspecting this aspect allows for a targeted and potentially quick resolution to the problem. Addressing the motor directly is essential as well, because if the motor is not operating effectively, it could be a straightforward fix, such as reconnecting loose wires or addressing minor wear and tear. By starting with a thorough inspection of these components, the operator can gather important information that guides the next steps. Other actions, such as cutting off the electricity or locking out and tagging the breaker, are usually addressed as secondary safety measures after identifying the problem. These measures are important for ensuring safety while performing maintenance but are not the immediate response needed to assess the communicator's condition. Placing the bar screen into service would typically be considered only if the communicator is nonfunctional due to a blockage issue related to influent debris, which would not necessarily be the first course of action the operator should take. Thus, checking the motor and looking for blockage is the most
