Abstract

Backgrounds: Automobile and automotive industries in developed and developing countries are important. There are many harmful factors in mechanics workplaces such as chemical and physical agents, ergonomics factors, mechanical and biological factors. Objectives: This study aimed to identify safety, health and ergonomically hazards and recommend the control measures in the automotive repair shops in Tekab city in Iran. Methods: Sixty-three car repair shops in the Tekab city were identified. The researchers with the participation of employees broke any of jobs into their constituent tasks and steps. Then the researchers identified each step hazards and calculated related risks. Finally based on the risk assessment and risk priorities, the control measures were recommended. Findings: Nine jobs were identified. Inhalation of acid and soldering mist vapor and contact with unsafe equipment is the most important accident in the battery repairing and lathing job respectively. Fire caused by thinner, gasoline, paint and resin, severe trauma to the hands and feet, and contact with welding flame is the most important accident in the painting, car smooth working and repairing radiator job respectively. Fire caused by gasoline and motor oil is the most important accident in the oil changes and tire change and mechanical technician jobs. Falling car on person is the most important accident in the front part of car repair and absorbers and exhaust repair jobs. Application/Improvements: Job safety analysis is a useful method for identifying hazards at vehicle mechanics job. Using this method can identify hazards and finally recommends appropriate control measures.

Abstract

Background: In order to control occupational accidents, it is essential to find out unsafe behaviors and their rate among
workers. This study was aimed to determine unsafe behaviors rate and offer some control measures. Methods and
Materials: In this descriptive-analytical study, safety sampling technique, interview and document review methods were
adopted. In a pilot study, the number of observations and samples were determined 3145 and 185, respectively. Finally,
in order to analyze the data, Chi-squared test and regression were used. Findings: The results showed that 25.08% of the
workers behaviors were unsafe. It was found that there is a significant correlation between unsafe actions and education
level (P>0.05) while the correlation between unsafe action and age, work experience, married status, job and time of
observations was not significant (P<0.05). Furthermore, the highest unsafe actions were observed in testing man and
workers above 51 years old and above 21 years of work experience. Application/ Improvements: Although the rate of
unsafe behaviors in study group was relatively low compared with unsafe acts, the improper use of personal protection
equipment was the most dominant problem. In order to reduce these behaviors, training programs, daily surveillance and
safety culture improvement among workers and authorities are strongly suggested.
