Question: When operating a wheel loader, particularly when reversing, why is it crucial to regularly clean the mirrors and windows, even if they appear only slightly dirty?
Answer options:
- Dirty windows and mirrors increase fuel consumption due to obstructed airflow. ✅ Even slight dirt or dust can significantly reduce visibility and distort perceived distances, amplifying blind spots.
- Cleaning prevents the glass from scratching and pitting over time.
- Reduced visibility causes excessive wear on steering components.
Correct answer: Even slight dirt or dust can significantly reduce visibility and distort perceived distances, amplifying blind spots.
Explanation: Even a thin layer of dirt, dust, or grime on mirrors and windows can significantly reduce light transmission, create glare, and distort reflected images, gravely impairing an operator's ability to accurately perceive distances and identify hazards in blind spots, as emphasized by CCOHS and CSA B335-15 'Safety standard for lift trucks'.
