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.

Faced with different representation models of a work situation whose centers of interest vary from one model to another, guides have been developed to try and analyze occupational risks in their entirety. However, the development of these guides poses a double problem: the completeness of this analysis and the order attributed to the analyzed occupational risks. This article aims to solve this problem through a systemic approach that allows to develop a hierarchical model of occupational risks invariants. Its exploitation allows to carry out an exhaustive analysis of occupational risks and consequently the elaboration of a long-term strategy of prevention.

Purpose The purpose of this paper is to deal with the allocation requirements of the dependability of the multiphase systems. Design/methodology/approach It consists of a proposal for a combined methodology based on the simultaneous use of decomposition systems and reliability allocation method. Findings In the developed methodology, the authors use the principles of risk assessment and propose a new formulation of weight allowance with reference to the structural-functional dependence. Practical implications The suggested methodology provides invaluable help to implementation process analysis. Originality/value The adopted allocation approach is based on the use of a three-dimensional model: temporal, structural and functional decomposition of systems.

Purpose The risk control is an unavoidable step in the risk management process. It is materialized by concrete actions of risks reduction in order to decrease their likelihood and/or their severity and also to preserve the environment. The paper aims to discuss this issue. Design/methodology/approach The main goal of the proposed methodology is to define the safety barriers (SB) that can be realized and their contribution to reduce major accidents scenarios that may occur in high-risk establishments. Findings In the proposed methodology, the authors present a combination of methods to prove the effectiveness of SB in an industrial installation. Practical implications The proposed methodology is a valuable help to industrialists to secure their industrial activities and preserve the environment at the same time. Originality/value The retained methods are often used separately for audit purposes or risk assessments of high-risk industrial facilities. In this paper, three methods have been selected and articulated in an approach for a better evaluation of risk control level.

The decision process is considered as the key element for the smooth behavior of systems. For non-complex or linear systems, this process usually follows clear rules or requirements, so that the decision will be easy to make without any difficulty. In the case of complex (non-linear) systems, the decision-making process is repeatedly challenged problems because of the interactions of several factors at the same time and because of the hazards characterizing these factors. This situation will worsen further if the system goes out of its normal operating range to fall into uncertainty. In this paper, we will try to make our contribution, to arrive at simplifying the decision-making process, while playing on human factors (ability, anticipation, risk-taking, etc.). As this process can be improved by the development of intelligent decision support tools.
