Analogy

Imagine a mine as a complex and dangerous maze. Hazards lurk around every corner, waiting to cause harm. However, with the right safety measures in place, it's like having a map and a flashlight to navigate the maze safely. Just as a map helps you avoid dead ends and dangerous paths, safety measures in mines help prevent accidents and protect mine workers from harm.
