Final answer:
Wearing safety glasses with a shade of 11 can create a hazardous situation because it significantly reduces visibility, making it difficult to see clearly in certain environments and tasks.
Step-by-step explanation:
Wearing safety glasses with a shade of 11 can create a hazardous situation because it may limit the amount of visible light reaching your eyes. Shade 11 is very dark and can significantly reduce the visibility, making it difficult to see clearly in certain environments such as a dimly lit area or while performing tasks that require precise vision. This can potentially lead to accidents or injuries.
