After ice obstructions are found in penetrations to cold storage, what is the recommended next step?

• A. Additional piping should be inspected
• B. Check on end of line—at a remote part of the system
• C. Remove entire system from service
• D. Remove obstruction from piping

Answer: (A)

When ice shows up in penetrations to cold storage, you first want to determine how widespread the issue is before acting on a single blockage. Inspecting additional piping helps you decide whether the ice is an isolated incident or part of a larger pattern affecting multiple penetrations or sections. This step informs the scope of corrective actions—such as improving insulation, venting, drainage, or heat tracing—and reduces the risk of future freezes or unexpected outages. Jumping straight to removing an obstruction or taking the entire system out of service is overly drastic without knowing how extensive the problem is. Checking only the end of the line could miss other affected areas. So, surveying other piping is the prudent next move to guide safe, effective remediation.
