What is a common safety-related sign of fatigue-related risk?

• A. Increased energy
• B. Reduced alertness, slower reaction times, mistakes, and poor judgment.
• C. Heightened focus
• D. Longer attention span

Answer: (B)

Fatigue drains the mental resources needed for safe performance. When you’re tired, your awareness lowers, reaction times slow, mistakes increase, and judgment can become poor. In safety contexts, these changes are red flags because they reduce your ability to notice hazards and respond promptly, raising the risk of accidents. Signs like increased energy, heightened focus, or a longer attention span would actually indicate the opposite of fatigue-related risk, so they don’t fit as indicators of fatigue.
