Background: Although the expansion of innovation in the industry has led to an increase
in the fast of works, production and productivity, it has also imposed an increase in the
musculoskeletal disorders. So, the aim of this study was determination the
risk level of work posture by REBA and RULA method among workers of assembly line
of a cosmetic manufacturing factory.
Methods: This study descriptive was carried out among the assembly line workers of a
cosmetic manufacturing factory in 2016. Six tasks (including 28 work postures) were
selected due to the most risk of inappropriate work posture factor. 18 postures were
evaluated by REBA method and 10 postures by RULA method.
Results: The results showed that the highest REBA score (score10) in the hair color
manufacturing section and the highest RULA score (score 7) related to the oxidant and
powder parts. The minimum score obtained by the REBA and RULA method was 5 and 4
(minimum 2 corrective action level), respectively.
Conclusion: To prevent musculoskeletal disorders and reduce the staff posture score in
pouring materials into the mixer or reservoir of manufacturing hair color, oxidant and
powder sections, corrective actions such as the use of a pump system for transferring
materials to the reservoir and the use of an footrest to avoid lifting the load to a height
above the shoulder are recommended.
