Which criterion is included in Class C mishap criteria?

• A. Overboard incident
• B. Nonfatal injury or illness resulting in loss of work
• C. Property damage less than $10,000
• D. Electric shock with no injury

Answer: (B)

Focus on how mishap severity is categorized for reporting. Class C covers nonfatal injuries or illnesses that still affect operations by causing time away from work. The reason this criterion is included is because losing work time reflects a real impact on readiness and safety performance, even if the injury isn’t severe enough to hit higher categories. The event signals a need to document and analyze the incident to prevent recurrence, maintain personnel availability, and improve safety practices. An electric shock with no injury doesn’t meet mishap criteria since there’s no injury. An overboard incident or larger property damage would typically push the event into a higher category.
