Which of the following is a Class C mishap criterion?

• A. One or more lost workdays
• B. Fatality or permanent total disability
• C. Inpatient hospitalization of three or more personnel
• D. Reportable damage of $2,500,000 or more

Answer: (A)

Class C mishap criteria are defined by injuries or illnesses that cause time away from work. When a mishap results in one or more lost workdays, it indicates a nonfatal injury that was serious enough to keep the worker from duties, but not so severe as to result in death, permanent disability, hospitalization of multiple people, or very large property damage. That’s why one or more lost workdays fits Class C best. The other scenarios describe more severe outcomes: fatalities or permanent disability are Class A; hospitalizing three or more personnel signals a higher-severity incident (Class B or A depending on other factors); property damage at or above a substantial threshold also pushes the mishap into Class A.
