The blind corner at shift change
At 14:00 the shift changes at a food-processing warehouse. Thirty production staff walk from the changing rooms to the packing lines through a 3.6 m main aisle that meets a cross-aisle at a blind 90-degree corner. The convex mirror on the corner post was cracked on Monday and has not been replaced, and the floor marking at the corner is worn away. The site speed limit is 8 km/h. You are the forklift operator and have 12 pallet moves to complete through that corner in the next 20 minutes; the line will stop if the pallets are late. Your horn works. A supervisor tells you to 'keep moving, they will hear you'.
1. Describe how you would approach the corner on each trip and what you would do differently as the shift-change pedestrian flow builds.

On every approach: slow to walking pace well before the corner, keep the forks low and the load tilted back, stop at the corner line, sound the horn, then creep forward and look both ways before entering. Because the mirror is cracked, I cannot rely on it, so I must physically clear the corner with sightlines. If the load blocks my view, I travel in reverse (where the truck and route permit) or use a spotter.
At shift change the risk changes from 'maybe someone' to 'a continuous stream of people'. Horn alone is weak here: plant noise may mask it, pedestrians are talking, and a horn gives no direction or distance. I would stop short of the corner and wait for a gap or for a marshal, or use an alternative route that avoids the pedestrian flow. I would not try to 'keep moving' through a crowd at 8 km/h; the site limit is a maximum, not a target, and near pedestrians the appropriate speed is walking pace or slower.
2. What interim controls and reports would you put in place for the rest of the shift, and who should own each one?

Interim controls, in order of effectiveness:
- Separate people and trucks: close the corner to forklift traffic during the shift-change window, or route pedestrians through a marked alternative walkway with a gate or barrier.
- Put a temporary mirror or a trained marshal at the corner until the permanent mirror is fitted.
- Re-mark the corner with cones or temporary tape so the stop line is visible today.
- Reduce speed locally, for example a 5 km/h limit through that aisle, enforced by supervision.
- Brief both shifts at the start-up meeting on the blind corner and the temporary route.
Ownership: I report the cracked mirror and worn marking to maintenance and EHS immediately and log a work order; the area supervisor owns the pedestrian route and the shift-change timing; the site traffic-management owner should review the layout, because the real fix is a permanent barrier or pedestrian gate at the corner. I would also record the near miss so it is not lost when the mirror is replaced.
3. How would you respond to the supervisor's instruction to keep moving?
Read the worked answer
I would be direct and specific: 'The mirror is broken, the floor markings are gone, and thirty people are about to walk through that corner. The horn cannot tell them which side I am coming from and they will not hear it over the line. I am stopping at the corner and waiting, or I am taking the long route.'
I would not simply refuse and walk away; I would offer the workable options: wait for the pedestrian flow to clear, use the alternative aisle, or ask for a marshal. If the supervisor continues to pressure me, I would ask for the instruction in writing, escalate to the shift manager or EHS, and record it. The operator has stop-work authority for a reason. A late pallet is a production problem; a pedestrian struck at a blind corner is a life-changing event, and the supervisor's instruction does not transfer the risk away from me or the people walking through that aisle.
