What If? Answer Probability Consequences Recommendation
Operator does not wear their seatbelt?
Employee could fall out of the seat or be crushed if forklift overturns
High Fatal Injury Seat belts, training
Forklift overturns? Employee could be injured, product and property damage
High Severe or fatal injury, damage to product

Task Step Hazards Required Safe PracticesStart Forklift Equipment failure Inspect equipment prior to use
Drive to pick-up location
Strike pedestrian, overturn forklift Go Slow, Look before moving, sound horn wear seatbeltup location horn, wear seatbelt
Retrieve Load Overturn forklift, drop load Do not overload, do not turn while lifting, move only stable loads, fully seat load on forks
Take Load to Destination
Overturn lift, strike a pedestrian, drop load, property damage
Drive in reverse if view is obstructed, go sow, sound horn, use mirrors at intersections, only carry stable loads
Place load in racks
Overturn lift, damage to racks, dropped load
Do not turn while lifting load. Verify clearance to avoid striking rack structure, verify load capacity of lift and racks
