How does being under physical or emotional stress affect safety in the shop?

• A. It has little effect on safety
• B. It improves concentration
• C. It leads to more carelessness
• D. It shortens reaction time

Answer: (C)

When you’re under physical or emotional stress, your attention and decision-making resources get pulled in different directions. The mind can become scattered, distractions rise, and tasks that require careful setup and precise steps may be rushed or skipped. In a shop, this means you’re more likely to miss a safety step, mishandle a tool, or misread a measurement, which is why stress tends to result in more carelessness. That carelessness increases the chance of accidents and injuries, so safety drops rather than improves.

The other ideas don’t fit as well. Stress often doesn’t improve concentration; it typically narrows focus and degrades performance. It also doesn’t reliably shorten reaction time—if anything, it can slow or flag unpredictably in demanding tasks, especially when hands or decision-making are involved.
