Background & objective: Safety training is believed to be one of the pioneering safety measures to improve the safety culture in organizations.The aim of this study was to determine the impact of training and technical interventions on providing a work environment with proper safety culture and understanding the risk of dangerous situations at height among construction workers.Methods: In this interventional study, 394 workers of different job groups in construction companies including impact driver operators, masonry workers, ironworkers and concrete vibrating operators were entered.Data were collected using "demographic", "safety culture" and "the risk of dangerous situations at height" questionnaires.Questionnaires were completed and collected in three stages: before the intervention, two months after the first intervention and two months after the second intervention (eight months after the first intervention).The data were analyzed using Bonferron's modulation tests (follow-up tests in variance analysis) and binary logistic regression test in SPSS version 23 software. Results:The findings of the present study revealed the significant impact of safety training on all components of the safety culture and also the empowerment of workers in understanding of risk of dangerous situations at height.The findings of this study, also revealed the significant improvements in safety culture, indicating the role of training along with technical intervensions as crucial factors in improving workers safety in organizations.Conclusion: Industries can prevent occupational accidents and their consequences by adopting proper safety and hygiene measures and engineering design through a coherent training program and achieve a sustainable industrial and development prosperity.In this regard, the findings of the present study showed that conducting training courses by involving workers and encouraging group discussion and expressing the importance of safety in the workplace as well as technical measures can positively influence workers' safety behaviors and promote safety culture.Exchange of views and sharing experiences, well-designed training programs, and devoting enough time can also be effective in promoting safe behaviors.
Background: disregarding safety requirements has made accidents of workshop mobile cranes as one of the main factors of injuries and death in civil-industrial projects. Since safety culture considered one of the most important activist indices while investigating the commitment of superior managers and other members of the organization to regard safety requirements, the present study aims at investigating the organization’s safety culture in civil and industrial projects and its relationship with regarding safety requirements of mobile cranes. Methods: the current study is descriptive-analytical and cross-sectional research conducted within 7 civil-industrial projects from 2018 to 2019. To investigate satisfaction levels of safety requirements, 141cranes have been used through a 72-item researcher-made checklist adapted from ASME B30.5 2018 standard and protective regulation of transportation vehicles and moving materials and objects of workshops. The research team has confirmed the validity and reliability of the checklist with CVR=0.68, CVI=0.82, and Cronbach’s alpha=α-0.90. To estimate safety culture levels 677 individuals of staff such as cranes operator, technician, expert, minor managers, middle managers, and superior managers have participated in this study through random sampling method, interview, and completion of safety culture questionnaire. To analyze data Kolmogorov-Smirnov tests, one way ANOVA and linear regression utilizing SPSS v25 have been employed (P-value < 0.05). Results: age average of study individuals equaled with 39.8 and average of their work experiences equaled with 12.29. Results out of this study revealed that there is a positive and meaningful relationship between organizations’ safety culture and consideration levels of safety requirements in mobile cranes. So that parameter of management commitment (0.001), safety preference degree (0.004), staff training (0.012) and information exchange level (0.041) have the most relationship with consideration levels of safety requirements. But there was no meaningful relationship between work conditions and consideration levels of safety requirements (0.075). conclusion: based on results of this study it seems that accidents resultant from mobile cranes occur more in uncommitted organizations so it is important to develop organizations’ safety culture through performance of academic interventions and inform organizations’ staff especially superior management and consequently increase the safety factor of mobile cranes in civil-industrial projects.
Nowadays, the change and dynamism of organizations are the basic principles; therefore, managers should modify the goals, plans and work procedures so that they can be compatible with the environment condition. The management of HSE is not excepted from this principle. The aim of this study was to evaluate the processes affecting HSE.
This study was a cross-sectional and applied study using the review of relevant documentation, interviews and brainstorming with experts, and the reviews of Best Practice to identify the HSE's processes.
After checking the HSE activities, the 5 processes of HSE training, managing the risks, events, emergencies and contractors and any changes in the other processes of the organization were also suggested.
The results showed that a process approaching the form of an intervention programed can be provided in order to have a better interaction between the HSE activities and organizations processes and workplace health promotion for the HSE activities.
Background This study aimed to intervene in the organization processes based on the HSE perspective and designing the processes of Health, Safety and Environment (HSE). Methods: This study is mixed methods research based on the case study. The processes of HSE were identified and designed by studying the relevant documentation, interview techniques and a focus group of experts, and also examining the best practice. Finally, the probability of improvement in the implementation of the suggestions was estimated. Results: After reviewing the HSE activities, all the important activities of HSE were identified. In examining the feasibility of the process design, the two processes of cost-benefit management and resilience strategy of the organization were not designed. To cover a number of identified activities, the five processes of HSE training, risk management and its effects, incident management, emergency management, and the management of contractors were suggested. Then, to cover other activities of HSE, a set of changes in eight processes was planned. Conclusion: This approach can lead to changes in other organizational processes. According to the results of the effects of improvement, it was specified that the proposed processes and interventions can have a significant effect on improving HSE indices.
Introduction: Noise is considered as a risk factor for a wide range of industrial environments, including construction industry. The aim of this study was to determine the relationship of job stress caused by noise exposure with sleep disturbance. Methods: This descriptive-analytic study was carried out among 134 workers of an Iranian construction industry. To assess the individuals' noise exposure in accordance with the ISO 9612: 2009, the eight-hour occupational exposure level was measured. To assess the occupational stress, the Parker Job Stress Questionnaire and Insomnia Severity Index were applied. Epworth Sleepiness Scale was also used to assess the sleep disturbance. Data were analyzed using Kolmogorov-Smirnov test, Pearson correlation test, and multivariate regression in SPSS version 23. Results: The results of Pearson correlation test and multivariate regression showed that noise can cause sleep disturbance by causing occupational stress in workers. Based on the results of this study, noise exposure, occupational stress, and sleep disturbance have a direct and positive relationship. In other words, increased noise exposure leads to occupational stress and sleep disturbance. Conclusion: Assessment of the noise exposure in workers of a construction industry showed that noise was a very important factor in the psychological problems of workers in this industry. In addition to the direct effects of noise on sleep disturbance, it can indirectly exacerbate the sleep disturbances.
