What percentage of accidents occurred when crews were merged or doubled due to absenteeism?

• A. 60%
• B. 40%
• C. 20%
• D. 70%

Answer: (A)

Shifts and how teams are staffed affect accident risk, especially when one absent crew member leads to merging or doubling of crews. When crews are combined to cover absenteeism, the workload piles up, coordination becomes more complex, and fatigue can set in. These factors raise the chance of mistakes, miscommunications, and unsafe conditions, so accidents tend to cluster in this scenario. The 60% figure reflects that the majority of accidents occur when crews are merged or doubled due to absenteeism, making it the best representation of that risk pattern. The other percentages would understate or overstate the actual relationship in this context, so they don’t match what the data show. This underscores the value of maintaining adequate staffing, clear handoffs, and measures to manage fatigue and workload.
