Readiness check

Is your cold storage built to keep cold without destroying itself?

A refrigerated warehouse is a building-sized cold box, and scaling up from a walk-in adds problems that will wreck the building if ignored: the freezer floor heaving, ice forming inside the panels, and a large ammonia charge that brings federal safety rules. Answer for how the facility is actually built and run. The score stays on your device; enter an email only if you want the cold storage readiness checklist sent over.

1. Does the freezer have a sub-floor heating system (or ventilated void) to stop frost heave?Yes, sub-floor heat installed and monitoredNot sure it is working or monitoredNo sub-floor heat under the freezer

2. Is the vapor barrier continuous on the warm side to stop the inward vapor drive?Yes, continuous sealed barrier, no breachesMostly, with some questionable spotsWe see ice forming in the panels or walls

3. Are the insulated panels and joints sealed and intact (no ice, no gaps, no damage)?Yes, panels sound and joints sealedSome forklift damage and open jointsNo, panels are damaged and icing

4. If the plant uses ammonia above the threshold, is process safety management (PSM) in place?Yes, PSM/RMP program current with detectionSome elements, not a full programNo PSM, or unsure of the charge

5. Do the doors and dock seals control infiltration (high-speed doors, air or strip curtains)?Yes, fast doors and seals, infiltration controlledDoors are slow and ice builds at openingsNo infiltration control

6. Is the refrigeration concurrently maintainable and redundant (you can service it live)?Yes, redundant and serviceable without losing tempSingle path, we risk itNo redundancy

7. Was the first pull-down done slowly to avoid thermally shocking the structure?Yes, a controlled staged pull-downNot sure how it was doneIt was cooled as fast as possible

8. Are temperatures, sub-floor heat, and ammonia detection monitored and alarmed 24/7?Yes, monitored, alarmed, and loggedSome monitoring, gaps in coverageNo real monitoring
