Work-related musculoskeletal disorders are multifactorial conditions that result in time loss, disability, and increased economical costs. The aim of the current study was to evaluate the role of the physical, environmental and psychosocial factors in the development of musculoskeletal disorders in workers in the production and assembly of auto parts in Qom city in 2021.
In this cross-sectional study, 211 participants through an inconvenience sampling method entered the study. The demographic characteristics of participants and the prevalence of musculoskeletal disorders were assessed by a self-report questionnaire and the Extended Nordic questionnaire, respectively. The mental workload was evaluated by the NASA-TLX index and the physical, environmental and psychosocial risk factors were evaluated by the Structured Multidisciplinary Work Evaluation Tool (SMET). The binary logistic regression method was used to show the role of the different risk factors in the development of MSDs.
Participants had an average age of 33.9 years (SD = 6.9). The lifetime prevalence of MSDs was obtained at about 77.72% in at least one area of the body. The neck, back, and shoulder areas were the most common regions. Gender, smoking history, surgery history, age, past surgery history, and sports history were most effective in the development of MSDs. In addition, subscales of mental workload play a role in causing pain in the shoulders, upper back, back and knees. SMET subscales play an effective role in the neck (OR = 1.396), upper back (OR = 1.663), hip, and knee, wrist/hand, and ankle/foot pain.
According to the role of various factors in developing disorders, the physical, psychosocial, and environmental factors should be considered simultaneously in planning preventive programs and ergonomics interventions.

Considering the reported positive effects of risk management practices and monitoring them by conducting risk assessments and achieving safety improvements, this study was conducted to assess the risks in the educational laboratories of Qom University of Medical Sciences.

This cross- sectional study was conducted in 13 medical and paramedical educational laboratories. To assess safety conditions in the laboratories, a comprehensive safety checklist was developed and in order to assess the risks of laboratories, a method called FMEA was used. Two trained occupational health and safety experts evaluated the laboratories under study and identified the hazards, completed the relevant checklists, and subsequently ranked them based on severity, occurrence and detection. Finally, a comparison was made based on the calculated Risk Priority Number (RPN) for each hazard.

In general, fire hazards and electrical hazards 54% of the laboratories have been accompanied normal risk (RPN< 70) and nearly 8% of the laboratories had critical fire and electrical risks including chemistry and immunology laboratories. In the case of equipment hazards, nearly 60% of the laboratories had critical or semi-critical risk levels. it is indicated that health exposure hazards were the most important hazards compared to the other ones. So that 61.5% of the laboratories had critical risk and 15.3 % of them categorized as semi- critical risk. The highest RPN allocated to the biochemistry and chemistry laboratories (RPN>250).

The results of this study showed that in general, three types of hazards, including health hazards, equipment and material storage, should be given priority.
