When ice obstructions are found in cold storage penetrations, which action is recommended?

• A. Inspect additional piping
• B. Remove obstruction from piping
• C. Remove entire system from service
• D. Check on end of line at remote part of the system

Answer: (A)

When ice shows up in cold storage penetrations, start by inspecting additional piping to gauge how widespread the blockage and freezing are. Ice often signals more than a single localized obstruction—there could be multiple penetrations or runs affected by the same temperature and drainage conditions. By checking nearby lines and related penetrations, you can determine if the issue is isolated or systemic, identify any shared causes (like poor drainage, insulation gaps, or valves left in a way that traps water), and plan a safe repair without causing unintended problems. Clearing one obstruction without looking for others can leave hidden blockages that may fail later or cause a surge when they’re freed. Removing the entire system from service is unnecessary and overly disruptive for a localized ice issue, especially if the system still has critical cooling or protection needs. Checking the end of a line at a remote part of the system doesn’t directly address the immediate ice in the penetrations and may miss other affected areas.
