What is an essential factor to ensure safe operation during the testing of an exchanger?

Using Personal Protective Equipment (PPE) is crucial for ensuring safe operation during the testing of an exchanger. PPE protects workers from various hazards they may encounter during the testing process, such as exposure to chemicals, high temperatures, or mechanical injuries. This gear can include safety goggles, gloves, hard hats, and specialized clothing, which serve as a barrier between the worker and potential dangers.

In the context of testing an exchanger, the environment may involve hazardous materials or conditions that could lead to injury if proper safety measures are not in place. By wearing appropriate PPE, workers minimize their risk of experiencing accidents or health issues resulting from these dangers, allowing the testing to proceed safely.

In contrast, factors like temperature control, correct water pressure, and inspection of gaskets are also important for the effective operation and integrity of the exchanger but do not directly protect the individuals performing the testing. While they contribute to the overall safety and functionality of the equipment, they do not serve as personal protection for workers on-site.
