Today’s conversation
A pressure gauge is an indication—not proof that stored energy is gone. Trapped pressure can remain between valves, behind obstructions, or in dead legs.
Talking points
- 01Confirm valve alignment.
- 02Use designated bleeds or vents where applicable.
- 03Consider trapped pressure between valves or behind obstructions.
- 04Verify zero energy through independent means.
- 05Stay out of the line of fire.
TAKEAWAYZero on the gauge ≠ zero energy.
