　　Quite a few accidents with pallet movers occurred in a Belgian manufacturing company,despite the companys efforts to improve occupational safety.A bowtie analysis yields an integrative overview of possible accident processes with these pallet movers,including management factors to prevent these accidents.Eight hazards have been identified: 1) load,2) speed and 3) acceleration of pallet movers,4) design and 5) condition of the workplace,6) condition material,7) operating the pallet mover,and 8) tripping hazard.These hazards can start accident processes,leading to central events of bowties,and to different consequences: injury,damage,and/or economic loss.Several safety barriers and management factors to prevent or mitigate central events have been linked to accident scenarios.These safety barriers and management factors do not primarily focus on individual behavioural aspects of operators,but focus on technological and organisational aspects.The pitfall of blaming the victim,which is often present in other methods focusing on individual behaviour of operators,is therefore reduced when using the bowtie method.Furthermore,indicators can be linked to the bowties to manage barriers and management factors in order to prevent or control pallet mover accidents.For the development of bowties,a multi-method design with dependent and independent data sources was used.This makes this bowtie analysis a general model,transferable to other settings with pallet movers.In addition,the combination of company specific and generic data sources leads to mapping the entire accident process,both reactively and proactively.
