Which of the following typically defines a Class D mishap?

• A. Injury severity
• B. Monetary loss
• C. Property damage
• D. Environmental impact

Answer: (B)

The way mishaps are categorized hinges on severity, using clear cost thresholds to separate levels. The lowest category is defined primarily by monetary loss—the total cost to repair, replace, or recover. When those costs stay under the established threshold, the mishap falls into the bottom category. Injuries, environmental impact, and property damage describe the results of the incident, but they don’t by themselves set the lowest category; they can push the mishap into a higher class if they are significant. So, a mishap with minimal or no injuries and only small losses in property or environment would still be classified as the bottom category as long as the monetary loss remains below the threshold.
