Operator Crushing Between Forklift and Fixed Objects
HighThe most serious hazard in pedestrian forklift operation is the operator being crushed between the rear of the machine (tiller handle area) and a fixed obstacle when reversing or turning. This occurs when operators lose awareness of their surroundings, reverse too quickly, or turn in confined spaces without adequate clearance. The forklift's rear counterweight section swings wide during turns, reducing the clearance between the machine and nearby walls, columns, racking, or parked vehicles. Operators can become pinned against these objects, suffering crush injuries to the pelvis, legs, chest, or abdomen. The risk is heightened in congested warehouses and construction sites where working space is limited and multiple obstacles exist.
Consequence: Severe crush injuries including fractured pelvis, broken legs, crushed torso, rib fractures, internal organ damage, and potentially fatal injuries. Survivors often face extended recovery periods, permanent disability, and inability to return to physical work roles.
Loads Falling from Forks During Stacking Operations
HighWhen operating walkie stackers to stack pallets at elevated heights (1.5m to 5m), loads can fall if they are unstable, poorly stacked, unevenly distributed, or exceed the machine's rated capacity. Raising loads too quickly, operating on sloped ground, or sudden stops can cause loads to shift and topple. Damaged pallets may collapse when lifted, or loads may slide off forks if not properly positioned. The pedestrian operator standing adjacent to or beneath the raised load faces direct falling object hazards. Surrounding workers in the stacking area are also at risk from falling pallets, boxes, or construction materials.
Consequence: Serious head injuries, crush injuries from falling pallets or materials, fractures, and potentially fatal injuries if heavy loads strike workers. Falling materials can also cause secondary hazards by blocking egress routes or damaging other stored goods.
Struck-By Incidents Involving Other Workers
HighPedestrian forklifts operating in shared work areas create struck-by hazards when workers on foot enter the forklift's travel path or operating radius. Visibility is often compromised when transporting loads that obstruct the operator's forward view, requiring reverse travel or reliance on mirrors. Workers may not hear electric forklifts approaching due to quiet operation compared to combustion engine equipment. In congested environments with multiple workers and machines, communication failures, inadequate separation between pedestrians and vehicles, and workers stepping backwards into forklift paths all contribute to struck-by incidents. The forklift's load, forks, or counterweight can strike workers causing serious injuries.
Consequence: Impact injuries ranging from bruising and lacerations to fractures, crush injuries, and head trauma depending on impact force and struck body area. Workers struck by forks face puncture wound risks and crush injuries to limbs.
Tip-Over of Pedestrian Forklift During Operations
MediumWalkie stackers can tip forward or sideways if operated outside their stability limits. Forward tip-over occurs when lifting loads exceeding rated capacity, lifting loads with the centre of gravity too far from the mast, or tilting the mast forward excessively while carrying elevated loads. Sideways tip-over can result from turning too sharply while carrying elevated loads, operating on sloped or uneven surfaces with raised loads, or travelling across ramps at unsafe angles. Tip-over events can crush the pedestrian operator if the machine falls toward them, or cause the load to fall striking the operator or nearby workers.
Consequence: Operator crushed beneath tipping machine, falling loads striking operator or surrounding workers, equipment damage, and potential secondary incidents if tipped machine blocks egress routes or strikes racking systems.
Collision with Racking, Doorways, and Structures
MediumPedestrian forklifts operating in warehouses with narrow aisles, construction sites with temporary structures, or facilities with low doorways face collision hazards. Operators misjudging clearances, traveling too fast for conditions, or operating in poorly lit areas may strike racking uprights, door frames, overhead pipes, or temporary barriers. Collisions can dislodge stored items from racking causing falling object hazards, damage building structures, or damage the forklift's mast, forks, or hydraulic components. Struck racking uprights may be weakened even if damage is not immediately visible, creating future collapse risks.
Consequence: Stored materials falling from damaged racking onto workers below, structural damage to buildings or racking systems, costly forklift repairs, and disruption to operations during equipment inspection and repair.
Battery Charging and Electrical Hazards
MediumElectric pedestrian forklifts require regular battery charging creating electrical and chemical hazards. Lead-acid batteries used in many machines require connection to charging stations rated for the battery voltage and capacity. Incorrect charging procedures, damaged charging leads, or faulty charging equipment can cause electrical shocks, short circuits, or battery explosions due to hydrogen gas accumulation during charging. Handling batteries during changeout operations (in machines with removable battery packs) creates manual handling and acid spill risks. Batteries can weigh 200-400kg requiring mechanical lifting equipment for safe handling.
Consequence: Electrical shock injuries potentially fatal depending on voltage and current, battery acid burns to skin and eyes, inhalation of acid vapours or hydrogen gas, explosion hazards from hydrogen accumulation in poorly ventilated charging areas, and manual handling injuries during battery changeout.
Repetitive Strain from Prolonged Tiller Handle Operation
LowOperating pedestrian forklifts for extended periods requires workers to maintain grip on the tiller handle while walking behind the machine, often in awkward postures. The tiller handle controls steering and is also used to activate drive and hydraulic functions. Prolonged operation can cause hand and wrist fatigue, particularly if operators grip too tightly or operate machines with poorly maintained controls requiring excessive force. Walking behind the machine for full shifts on hard concrete surfaces contributes to foot and lower back fatigue. Operators who perform these tasks repetitively over months or years face cumulative musculoskeletal disorder risks.
Consequence: Hand and wrist pain, repetitive strain injuries affecting fingers and forearms, chronic lower back pain from prolonged standing and walking on hard surfaces, and foot pain from inadequate footwear or prolonged weight-bearing on concrete.
