Safety Alert

What Happened

A water cart reversed into the blind spot of a stationary grader on the Pit 4 access ramp. The water cart operator did not conduct a 360-degree walk-around before reversing and was relying solely on mirrors. The grader operator saw the approaching water cart and sounded the horn, causing the water cart to stop approximately 1.5 metres from contact. Both operators were uninjured.

Why It Matters

Blind spot incidents account for approximately 25% of all vehicle interaction events on site. Water carts have particularly large blind spots due to the tank configuration. Relying on mirrors alone is insufficient to manage reversing risks. This event demonstrates that the 360-degree walk-around is not optional — it is a life-saving control.

Immediate Actions Required

1. 1All water cart operators to complete mandatory 360-degree walk-around before every reverse movement — no exceptions
2. 2Proximity detection systems on water carts to be audited — non-functional systems to be repaired immediately
3. 3Install additional convex mirrors on all water carts to reduce blind spot zones
4. 4Review traffic management plan for Pit 4 access ramp — consider implementing one-way traffic flow

Key Learning

Mirrors show you what is there — a walk-around shows you what is there AND what could move into your path. The 360-degree walk-around takes 30 seconds and could save a life. Never reverse without checking. If you are unsure, get a spotter or get out and look.
