Assessment of Posture and the Impact of Technical Interventions on Its Improvement in Petrochemical Staff in 2018

Introduction: Musculoskeletal disorders are one of the prevalent factors that lead to absenteeism at work. The purpose of this study was to evaluate the physical posture and methods to improve workstations in the petrochemical industry. Methods: This interventional study was carried out at the Petrochemical Company and according to the type of work and posture evaluation using two methods QEC and LUBA. Ergonomic chair design was done by examining the anthropometric dimensions of the staff and then Posture re-evaluated and data were on paired t-test statistical tests analyzed by SPSS19. Results: In the QEC method 100% observations of fourth level loading workers in the loading section were in the fourth level and all workers in the bag sewing sector were in the third level. Posture evaluation by LUBA showed that 50% of workers' postures were in Area 3 of the Corrective Action Schedule and 37.5% of Postures in Area 4 of Corrective Action Table 3. Also, after intervention 28% frequency was in third level and 72% in QEC method. The LUBA showed that 20 percent of workers' postures were in Area 3 of the Corrective Action Table and 80 percent of Posters in Area 2 of the Corrective Action Table. Conclusions: These two methods have shown similar results for postural evaluation. Therefore, it can be concluded that proper application of optimized design will result in improved postures in the workplace. And prevented musculoskeletal disorders.
