The validity of the questionnaire was confirmed by the professors using face and content validity methods, and the reliability was also confirmed using Cronbach's alpha coefficient. In this research, structural equations based on path analysis in SMART PLS software were used to analyze and test research hypotheses.
Results: The impact of ergonomic principles on the burnout of Ilam Petrochemical employees is negative and significant with coefficients (T = 12.26, R2 = -0.42), and the cultural impact of safety on burnout is also negative and significant with coefficients
(T = 14.07, R2 = -0.32). is, the test of the main hypothesis shows that safety culture moderates the effect of ergonomic principles on job burnout and causes more reduction of job burnout.

In this research, path analysis in SMART PLS software was used to analyze and test the research hypotheses.
Results: Corona anxiety has a significant effect on job burnout with coefficients (T=11.22 = 0.42, R^2) and job stress with coefficients (T=9.24 = 0.48, R^2). The effect of burnout on job stress is also significant with coefficients (T=9.24 = 0.38, R^2). The VAF effect coefficient for the effect of corona anxiety on job stress with the mediating role of burnout is equal to 0.51 and its significance coefficient is 7.52. Therefore, the mediating role of job burnout between the two variables corona anxiety and job stress was confirmed.
