In many work environments,human errors are of great importance, since they resultin adverse events. Therefore,in order to prevent or reduce the consequences of human errors, itis necessary to identify the cause interpolation. The aim of this study is to identify, assess and manage the risks of human errorsin Desalting unit & Compression Station of maroon. After the assessments of different parts of the control room in desalting unit in termsof health and safety, in order to identify risks and potential damage to human factors (critical tasks), Walking & Talking Through methods was used.In order to analyzethe critical tasks in desalting unit and compressionStation,Hierarchical Task Analysis (HTA) was applied. Then, the risks and potential human damage wereevaluated and classified in view of Probability of occurrence and Intensity of effects. HumanHazop method was used in the process of risk assessment.The results of calculating risks of human Hazop work sheet in Maroon units indicate that the most important reasons behind errors in this company are as follows : a) not performingjob tasks (%88.33) as themost important job tasks, and b) human errors with the highest percentage of (% 41.66).The consequences of human errors can be classified in 3 categories : 1)Economic consequences (%44.96) 2) management consequences ( %32.55) 3) Environmental consequences (%22.48).Human hazop method can be used for eliminating the occurrence of human errors and also reducing the intensity of theirconsequences , by altering the education, designing , safety systems and instructions, wich in turn increases the .tolerance of errors indesigns or operations
