What should be the initial response when a hydraulic fluid leak is detected?

When a hydraulic fluid leak is detected, the appropriate initial response is to shut down the system immediately. This action is critical because hydraulic fluid leaks can lead to significant safety hazards, including fire risks, equipment damage, and compromised system integrity. By shutting down the system, you prevent further fluid loss and minimize the risk of potential accidents that could occur if the equipment continues to operate under compromised conditions. Immediate action helps to ensure the safety of personnel and the protection of equipment until the leak can be properly assessed and repaired.
