How long is long duration security?

How long is long duration security?

• A. Greater than 12 hours.
• B. 6-12 hours.
• C. 24-48 hours.
• D. 12 hours exactly.

Answer: (A)

Long duration security is defined by how long the shift lasts—anything beyond a 12-hour period. The threshold is set at more than 12 hours because fatigue becomes a significant risk once a shift passes that point, requiring measures like relief security, proper handovers, and rest planning to maintain performance and safety. So the best choice is the one that says greater than 12 hours, since any duration over 12 hours qualifies (for example, 13, 16, or even 24 hours). The other options either cap at or specify exactly 12 hours, or only describe a longer window (24-48 hours) that doesn’t cover all long-duration cases.
