dominant occupational injuries and disabilities in developed and developing
countries. The RULA technique is one of the best methods for assessing upper
limbs postures. The purpose of this study was to investigate the working postures
using RULA and ergonomic interventions in the quality control unit of a glass
manufacturing company.</span></p>

the mirror control workstations of a glass manufacturing company. To assess
workers’ postures, the RULA technique was applied before and after the
intervention. After data analysis, corrective engineering measures were
recommended and implemented in all workstations.</span></p>

Accordingly, 60% of workstations were in action level of 3 (i.e. investigation
and changes are required soon) and 40% of workstations were in action level of
4 (i. e. investigation and changes are required immediately). After
