Which class of leak requires immediate attention?

Class 3 leaks require immediate attention because they are categorized as major leaks that consistently flow liquid under pressure. Such leaks can lead to significant operational hazards, including potential damage to equipment, safety risks to personnel, and environmental concerns. The urgency of addressing Class 3 leaks stems from their potential to escalate if not controlled swiftly, making it essential for maintenance personnel to respond immediately to mitigate any adverse effects.

In contrast, the other classes of leaks are less severe and do not pose the same immediate risk. Class 0 refers to no leak, Class 1 is a minor leak that may require attention but is not critical, and Class 2 is a situation that indicates a need for maintenance but is not as urgent as a Class 3. Understanding the distinctions between these classes helps personnel prioritize their response effectively during maintenance operations.
