ZIP LIP may be broken when?

The practice shown here is that safety overrides routine silence. You may break the ZIP LIP rule whenever staying quiet would jeopardize the safety of the flight—when timely communication or action is needed to prevent an unsafe situation. So, you would break it as required to ensure safety of flight—for example, to warn another aircraft, report an unexpected hazard, or coordinate with air traffic control during an emergency or abnormal situation. This isn’t about waiting for someone else’s permission, nor is it limited to being in a particular phase like the pattern, and it isn’t permanent. It’s allowed precisely because safety takes precedence over keeping quiet.
