Improving body posture while fueling with a newly designed pump nozzle

Sayyahi Z., Mirzaei R., Mirkazemi R.

International Journal of Occupational Safety and Ergonomics

2016

Vol. 22, No. 3

327--332

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.
