Abstract
BACKGROUND:
Although petrol pumps are a very common and highly used simple technology, their design consideration for comfort and safety to prevent high-pressure load and musculoskeletal injuries to the body is a neglected area in many countries including Iran.
OBJECTIVES:
This study attempted to design a new pump nozzle, and to assess the differences in musculoskeletal load related to body posture when a price/volume display is mounted on the pump nozzle.
METHODS:
For postural analysis, photographs recording the posture of 100 randomly selected customers while fueling at petrol pumps and the rapid upper limb assessment (RULA) technique were used.
RESULTS:
The results of this study showed that RULA scores improved significantly after the newly designed pump nozzle was used.
CONCLUSION:
The newly designed pump nozzle is useful in reducing load related to body posture while fueling.
