If a machine is obviously leaking, __________.

When a machine is obviously leaking, the appropriate response is for the employee to notify a supervisor. This action is essential because leaking fluids can indicate underlying issues that may affect the machine's performance, safety, and the overall efficiency of operations. Notifying a supervisor ensures that the problem is assessed by someone with the authority and experience to determine the next steps, including whether immediate repairs or further investigation is required.

In a Total Productive Maintenance (TPM) context, addressing such issues promptly is crucial to minimize downtime and prevent more significant problems in the future. It reinforces a proactive maintenance culture, which is central to TPM. The responsibility for repairs typically lies with specific maintenance personnel rather than individual employees, ensuring that qualified individuals handle the situation effectively.

Continuing to work as normal in the presence of a leak could pose significant safety risks and lead to further damage, while ignoring the leak until the next inspection could result in catastrophic failures, increased maintenance costs, and reduced productivity. Therefore, notifying a supervisor is the most responsible and effective course of action in this scenario.
