Workplace accidents (WAs) are and will remain a major concern for organizations’ managers. Their control requires putting in place a prevention strategy framed by several factors (human / social, economic, regulatory ...). The successful implementation of this strategy is conditioned on the ground, by the junction of three essential stages, namely: the analysis, evaluation and control of WAs. These three stages are interdependent where a successful control of an action plan is conditioned by a thorough assessment of an accident risk criticality. The latter depends on a good analysis of the accident. Indeed, a good analysis of WAs largely conditions their prevention strategy and that is why the analysis of WAs occupies a prominent place in such strategies. WAs analysis is conducted using appropriate models referred to as "WAs analysis models". Among those cited in the literature, we quote the model 24 that is a contemporary and more systematic model compared to other models. In this context that this article fits in, which aims to highlight its multiple contributions for the analysis of WAs.

The workplace, and more particularly the healthcare sector, has recently experienced a staggering increase in violence. These aggressive behaviors are resulting in considerable consequences on healthcare workers, both in terms of mental and physical health. In light of this observation, this study aims to provide a quantitative analysis of the potential causes leading to violence in Algerian hospitals, which have become the place where tensions arise, especially during these uncertain times caused by the COVID-19 pandemic. Therefore, we started with conducting a field survey, in order to highlight the main causes behind this violence, as well as the strategy in terms of how it is managed as a risk. Then we used ISHIKAWA diagrams to classify predefined causes into several categories and anticipate the likelihood of such violent behaviors. Finally, the results of this study revealed that working conditions were the main cause of violence in Algerian hospitals. In order to remedy this gap, we recommend improving the healthcare staff well-being, as well as prioritizing proactive measures preventing violent behaviors.

An increasing interest and efforts are being made at all levels by academics and practitioners to protect the workers and encourage the development of strategies and approaches to reduce the number of accidents at the workplace, improve the safety performance of the industrial companies and preserve the environmental health. In spite of the continuous efforts of the Algerian companies to improve their health and safety performance, high number of accidents and ill-health problems among the Algerian companies are still being recorded. In terms of definition, the Environmental Health refers to human’s health aspects including quality of life. These aspects are defined by the physical, biological, social and psychosocial factors of the environment. It includes also the theory and practice of assessing, correcting, controlling and preventing these factors in an environment which may potentially affect human’s health.This paper comes to explore the contribution of the alignment of the cluster cultural aspects (CA), health and Safety strategy (H&SS) and people (P) as a way to improve the environmental health, particularly the Musculoskeletal disorders (MSDs) that present one of the prominent and significant health problems at work.
