The internationally recommended maximum duration for a screener to continuously perform screening duties, especially involving tasks requiring high concentration like X-ray image analysis or physical frisking, is typically limited to 20 minutes.
Limiting the continuous screening time is crucial to prevent fatigue, maintain alertness, and ensure effectiveness in detecting threats. After this period, screeners should be rotated to other less demanding tasks or take a break.
Different security agencies and countries may have slightly varying guidelines, but 20 minutes is a widely adopted best practice in aviation and other high-security screening environments. This practice enhances overall security performance by reducing the risk of human error due to tiredness or monotony.
