When should you check for leaks in a pneumatic or hydraulic system?

Checking for leaks in a pneumatic or hydraulic system before opening any system components is crucial for several reasons.

First, assessing for leaks prior to disassembly ensures the safety of personnel. High-pressure systems can contain fluids under significant pressure, which, if released suddenly, can cause injury or damage. By identifying any leaks or pressure issues upfront, technicians can take necessary precautions such as relieving pressure or implementing appropriate safety measures.

Additionally, detecting leaks beforehand can help establish if there are any system deficiencies that might need addressing before any components are manipulated. This proactive approach can save time and resources, as it allows for repairs or adjustments to be planned before entering a potentially hazardous environment.

While checking for leaks after a pressure drop or at the end of operations is important, these actions do not prioritize safety as effectively as assessing for leaks before opening the system components. Regular checks are essential, but the timing is critical in preventing accidents and ensuring the reliability of the system’s operation.
