Had a near‑miss during a 02:30 screen‑out on a 10k spread when the manual dump took two hands and five seconds to move; anyone running air‑actuated, spring‑return failsafes on the zipper or treating manifold, and how are you integrating them with ESDs and pressure alarms to speed shut‑in without creating inadvertent trips? I’m hunting for setups that cut human load during high‑rate events and want real‑world notes on maintenance intervals and cold‑weather reliability.
