What term describes a release that results from a broken or damaged valve and may last from several seconds to several minutes?

• A. Continuous leak
• B. Valve seepage
• C. Rapid relief
• D. Flash release

Answer: (C)

When a valve is broken or damaged, the stored energy and pressure behind it push material out quickly, producing a short, high-rate discharge. This rapid dump happens until pressure drops enough or the release is stopped, so the duration is typically only a few seconds to a few minutes. That makes the term a good fit because it specifically describes this transient, fast relief rather than a slow, ongoing leak or a different kind of release. Continuous leaks would keep going steadily; valve seepage implies only a small, slow seepage; flash releases involve vaporization but aren’t defined by a transient valve failure with a brief duration like this.
