A wheel loader is clearing snow in a parking lot. A pedestrian unexpectedly walks into your machine's 360-degree 'zone of awareness' (approximately 10 metres). What is the minimum safe distance a pedestrian should maintain from operating heavy equipment, as per general OHS guidance?

Question: A wheel loader is clearing snow in a parking lot. A pedestrian unexpectedly walks into your machine's 360-degree 'zone of awareness' (approximately 10 metres). What is the minimum safe distance a pedestrian should maintain from operating heavy equipment, as per general OHS guidance?

Answer options:

• 1 meter, if eye contact is established.
• 3 meters (10 feet).
• 5 meters (16 feet). ✅ At least 15 meters (50 feet) or outside the swing radius/reach of the equipment.

Correct answer: At least 15 meters (50 feet) or outside the swing radius/reach of the equipment.

Explanation: While specific site rules may vary, CCOHS and OHS best practices generally recommend that pedestrians maintain a minimum safe distance of at least 15 metres (50 feet) from operating heavy equipment, or outside of the machine's swing radius or maximum reach, whichever is greater. This 'zone of awareness' provides a buffer for unexpected movement and blind spots.
