Introduction: Occupational health is one of the important issues that can affect productivity and economic development of an organization. This study aimed to determine the effect of didactic interventional Ergonomic-Safety program on workers’ productivity of an assembling industry.
Methods and Materials: This interventional study was conducted on 54 workers of assembling part of an electronic industry. Firstly, QEC method was used for Ergonomic assessment of work place and Hersey-Goldsmith questionnaire was applied for assessment of productivity. Then a comprehensive program was provided using findings of first stage assessment and identifying of existing failures. Second assessment of Ergonomic condition and productivity was done again by using QEC method and Hersey-Goldsmith questionnaire within three month of interventions. Data was analyzed by using of R software.
Results: Mean total productivity score and mean whole body score of QEC were 75.24 and 99.40 in before intervention phase respectively. In after intervention phase, Mean total productivity score and mean whole body score of QEC were 80.16 and 97.92 respectively. Data analysis by paired-samples t-test shows that difference of productivity score in before and after intervention phase was significant (P-value˂0.05). But difference of whole body score of QEC score in before and after intervention phase was not significant (P-value>0.05).
Conclusion: Accomplishment of Ergonomic-Safety intervention had a positive effect on productivity score whereas had not significant effect on general condition of body limbs.
