01Understand the designed shutdown state
Some systems depressurize selected sections as part of their approved sequence. Review the flow diagram and manual before interpreting every pressure drop as leakage. Identify which vessel or line the gauge actually represents.
02Record conditions over time
Log pressure, temperature, valve states and any continuing gas use. Cooling after operation can change pressure in a closed volume. A comparison that ignores temperature or a small connected consumer can overstate a suspected leak.
03Investigate safely
Have qualified personnel use suitable detection and isolation procedures within the approved design. Do not defeat a normal depressurization function to retain pressure. After repair, compare the same defined standby condition and record the result rather than relying on a quick gauge glance.
