Forklift–Pedestrian Interface at a Cold-Storage Distribution Center
Northline Cold Storage operates a 24/7 distribution center with 14 powered industrial trucks and roughly 60 pedestrians per shift. In the last six months, near-miss reports rose 38%, with three recordable injuries: two foot contusions and one fractured hand. Telemetry shows average forklift speed in the main aisle is 7.8 mph despite a posted 5 mph limit; 40% of operators have not been evaluated in 24 months. Eight intersections have blind corners, and aisle width is 12 ft. The safety committee documented 70% of near misses at three intersections near the break-room entrance, where employees cross to reach lockers. Management proposes a 30-day 'stop, look, and listen' campaign plus yellow floor tape at a cost of $3,500. The safety committee wants rigid barriers, pedestrian gates, and speed governors, estimated at $85,000, but the plant has not approved capital. The site has no leading indicator beyond near-miss counts, and the last hazard assessment predates a 2022 layout change that moved the break room.
1. Using the data in the setup, evaluate whether the proposed administrative campaign is sufficient. Identify the highest-risk exposure and explain how you would apply the hierarchy of controls.

Administrative controls are the weakest option, and the data undercut them. The 70% concentration at three intersections near the break room shows exposure is predictable and location-based, not a matter of individual carelessness. Average speed of 7.8 mph in a 5 mph zone suggests the current controls are not self-enforcing; a 30-day campaign will decay. Forty percent of operators without recent evaluation is a training-compliance gap, not a substitute for engineering. Apply the hierarchy: first eliminate or reduce exposure by separating pedestrians from forklifts at the three intersections with rigid barriers and gates, and redesign break-room access to avoid the main aisle. Second, engineer speed control with governors or zone-based speed limiting. Third, use enforcement and retraining. Floor tape is useful only as a supplement. If capital is constrained, install barriers at the three highest-risk intersections first and use temporary hard barricades while funding the rest.
2. Propose a 90-day action plan with specific priorities, budget allocation within $85,000, and two metrics to track effectiveness.

90-day plan: Days 1-10, retrain and evaluate all 14 operators; post temporary pedestrian barricades at the three break-room intersections; audit speed compliance daily. Days 11-45, install speed governors capped at 5 mph on all trucks, install rigid barriers and pedestrian gates at the three intersections, and reroute break-room access. Days 46-90, complete remaining five intersections, refresh the hazard assessment, and add leading indicators. Budget: $28,000 for barriers and gates at three intersections; $21,000 for governors; $10,000 for training and certification; $12,000 for rerouting and signage; $8,000 for audit and assessment; $6,000 contingency, totaling $85,000. Metrics: near-miss rate per 100 employees per month, with a target 50% reduction in six months, and percent of telemetry readings over 5 mph, with a target below 5%. Also track pedestrian-forklift proximity events weekly. The plan prioritizes exposure reduction over awareness because the data show a location and speed problem.
3. How would you validate the hazard assessment after the layout change, and what would trigger reassessment?
Read the worked answer
Validate with a fresh hazard assessment that maps pedestrian flows, forklift routes, blind corners, break-room access, and shift changes. Use direct observation at peak times, telemetry, near-miss interviews, and a layout drawing; involve operators and pedestrians. Confirm that controls perform as intended: governors actually limit speed, gates are used, and barriers do not create new pinch points. Reassess whenever layout, traffic flow, product mix, shift patterns, or truck type changes; after any near miss or injury at an intersection; and at least annually. Also reassess if telemetry shows speed compliance decaying or if near-miss reports shift to a new location. Document the assessment and link it to the capital plan so layout changes trigger review before construction, not after.
