What action should be taken if a machine's brakes are found to be malfunctioning?

If a machine's brakes are found to be malfunctioning, isolating the machine and ensuring it is not used is the most responsible action to take. This approach minimizes the risk of accidents or further mechanical issues that could arise from operating a machine with faulty brakes. By removing the machine from service, you help protect not only the operator but also other personnel working in the vicinity.

It prevents the potential danger associated with brake failure, which could result in collisions or loss of control, thereby ensuring safety is prioritized. While reporting to a supervisor is important and should be part of the protocol, isolating the machine must take precedence to immediately address the risk it poses. The other choices may involve actions that could lead to unsafe conditions, as attempting repairs on-site without proper tools or expertise can exacerbate the problem, and continuing to use the machine, even with caution, could lead to severe consequences if the malfunction occurs while in operation.
