What is an important practice before performing maintenance on machinery?

Before performing maintenance on machinery, it is crucial to turn off and disconnect from energy sources to ensure the safety of anyone working on or near the equipment. This practice minimizes the risk of accidental machine activation, which could lead to severe injuries or even fatalities. By isolating the equipment from its energy sources, you create a safe environment where maintenance can be conducted without the threat of unintended movement or power surges.

This step is a fundamental aspect of maintenance protocols and reinforces the importance of safety first in workplace practices. It ensures that technicians can focus on their tasks without worrying about the machinery operating unexpectedly, thus facilitating a more efficient and safe maintenance process.
