Abstract
Background:Small and medium-sized enterprises (SMEs) include a large part of manufacturing jobs and play an important role in developing national economics and employment.Objectives:The present study aimed to investigate occupational health problems and safety conditions among SMEs in Shiraz, Iran.Methods:This cross-sectional study was carried out on 711 SMEs, including 371 small enterprises (fewer than 25 workers) and 340 medium enterprises (25–99 workers), in Shiraz, Iran. The participants were selected randomly among the workplaces under the coverage of social security insurance. The researcher-made questionnaire, which consisted of demographic characteristics, the frequency rate of occupational accidents, and exposure to workplace harmful agents, were distributed among participants.Findings:The results showed there were significantly more physical and chemical harmful agents in medium enterprises compared to small ones (P < 0.001). However, the frequency rate of accidents in small enterprises was significantly higher than in medium enterprises (P < 0.001). Also, there was no significant difference between the studied enterprises in ergonomic hazards, except for awkward posture, whose frequency rate was significantly higher in small enterprises (P < 0.05). Finally, among the reported symptoms, the prevalence of eye, skin, ear, and respiratory symptoms was significantly higher in medium enterprises compared to small enterprises (P < 0.05).Conclusions:Occupational health and safety (OHS) regulations in medium enterprises have led to improved OHS conditions compared to small enterprises. Therefore, small enterprises should be included in OHS regulations.
Highlights
Small and medium-sized enterprises (SMEs) are independent firms that employ less than a given number of workers [1]
The people working for medium enterprises had higher levels of education, occupational medical examinations, and work shifts compared with employees in small enterprises (P < 0.001)
The frequency rate of accidents in small enterprises was significantly higher than medium enterprises (P < 0.001)
Summary
Small and medium-sized enterprises (SMEs) are independent firms that employ less than a given number of workers [1]. The Statistical Centre of Iran has divided enterprises based on the number of workers so that micro enterprises are those with fewer than 9 workers, small enterprises have 10–49 workers, and medium enterprises have 50–99 workers [9]. Methods: This cross-sectional study was carried out on 711 SMEs, including 371 small enterprises (fewer than 25 workers) and 340 medium enterprises (25–99 workers), in Shiraz, Iran. The frequency rate of accidents in small enterprises was significantly higher than in medium enterprises (P < 0.001). There was no significant difference between the studied enterprises in ergonomic hazards, except for awkward posture, whose frequency rate was significantly higher in small enterprises (P < 0.05). Conclusions: Occupational health and safety (OHS) regulations in medium enterprises have led to improved OHS conditions compared to small enterprises.
