The Development Trend of the Occupational Health and Safety in the Context of ISO 45001:2018

: The main task of safety and health at work is to protect the most important thing we have, the health of each of us. Employers are able to anticipate and prevent risks by properly implemented occupational safety and health management systems. The basic task of the article is to describe the history of safety management systems to identify the state of implementation of the ISO 45001 system in the world. Subsequently, the article describes the ISO 45001 standard from the perspective of the PDCA cycle and describes the beneﬁts and importance of implementing the ISO 45001 standard. The conclusion of the article deals with the development trend of the occupational health and safety management system according to STN ISO 45001:2019 in the context of occupational accidents in the conditions of the Slovak Republic.


Introduction
More than 6300 people die every day as a result of an accident at work or an occupational disease, which is a huge burden on organizations and society as a whole [1,2].It is an alarming number and is proof that measures need to be taken in the area of occupational safety and health management (OH&S), which will ultimately lead to a reduction in overall accidents and morbidity.One of the important steps is the implementation of the ISO 45001 standard, which employers can apply in order to ensure more effective health and safety.
New approaches in the occupational safety and health management system require that everyone be aware of the risks they face in the workplace and in their daily lives [3,4].The employer's obligation is to identify the risks associated with the work process, to implement risk elimination or minimalization measures, and familiarize its employees with residual risks [5,6].
The implementation of the ISO 45001 standard is expected to give priority to an overall improvement in occupational safety and a reduction in accidents at work and occupational diseases [1,7].

History of Occupational Safety and Health
Historically, developments in the field of occupational safety and health (OH&S) have been mainly based on efforts to prevent accidents arising from the use of technical equipment in the work process.In general, it is possible to outline the periods in the development and understanding of safety and its scope as follows (Figure 1).
Thus, the current period in particular has seen an intensive increase in requirements for the application of risk management theory in such a way that management at different levels and in different activities is effective and takes into account the visions of possible socalled catastrophic scenarios.Their probability is rated very low, but the consequences can have socially serious effects.These are, for example, activities related to spatial planning (risk assessment in planning the production or use of hazardous substances), construction of new facilities (determining the type and extent of zones in terms of explosion hazard), transport of hazardous substances (setting safety programs), etc. [5].

The European Union's (EU) health and safety policy focuses in particular on a broad understanding of these principles of managing human protection against adverse effects, applying the new rules in practice.According to the "Community strategy" in the field of health and safety, the policy was based on the so-called holistic approach.The call for a holistic approach is, in a sense, a call for the integration of all aspects of work.The Community strategy has thus given impetus to the wider application of integrated management systems [5,8].

Historical Development of Occupational Safety and Health Management Systems
With the growing number of many different management systems, the issue of their successful implementation and continual meeting of the requirements has been increasingly coming to the foreground [9].All activities of any organization involve risks [10].A management system must ascertain that a manufacturing process satisfies its defined usage without any undesirable failures or risks [11].
The history of health and safety management systems (Table 1) is connected with the The protection of human beings at work is understood as one of the basic political principles based on the Declaration of Fundamental Human Rights and Freedoms.However, it is not just about maintaining life and health.The protection of workers and others against the adverse effects of work and the working environment must be managed in such a way as to take account of all aspects relating to work.Thus, part of the management is also the creation of conditions for satisfactory work, well-being at work, social protection of employees, and legal protection of other persons, as well as protection of material values, work, and environment.Therefore, in connection with the protection of employees, it is also necessary to address such factors as stress, workload, work monotony, working conditions, labor relations, social equipment of workplaces, fair remuneration, etc. [5].

The history of health and safety management systems (Table 1) is connected with the development in the field of management, especially the quality management systems (ISO 9000) and environmental management systems (ISO 14000).
Table 1.An overview of some occupational health and safety management systems [5].More than two decades ago, legislative requirements for risk control through systematic management and the emergence of Occupational Health & Safety Management System (OH&SMS) standards and respective certifications contributed to the development and broad use of various OH&SMS models [12,13].

Marking
Until 2018, the OH&S management system did not take the form of an ISO standard, although the publication of the OH&SMS manual as an English standard (BS) created a uniform framework for the implementation and certification of OH&S management systems.Since 2018, the new standard ISO 45001:2018 has been in force, which already has its standardized form.
ISO 45001:2018 "Occupational health and safety management systems-Requirements with guidance for use" specifies the requirements that an OH&SMS must own to allow an organization to effectively control its own risks and opportunities within this scope [14,15].

Overview of the State of the Health and Safety Management System ISO 45001:2018 in the Context of ISO Standards in the World
In 2020, a survey of the number of ISO standards was carried out, which contains data on valid certificates issued by accredited certification bodies around the world.From this data, we have gained some valuable insights regarding the currently available ISO standards.The survey reports data on the total number of valid certificates from accredited certification bodies as of 31 December 2020.Over 1.5 million valid certificates against the 12 Type A (requirements) management systems standards surveyed have been reported, an increase of 235,790 from the previous year.In percentage terms, this was an increase of 17%.Thus, the global trends in ISO certification are shown in Tables 2 and 3.The survey shows that, between 2019 and 2020, the number of ISO 9001 (Quality Management Systems) increased by 4%, ISO 14001 certificates (Environmental Management Systems) increased by 11.5%.The highest increase was recorded in the ISO 45001 standard (Occupational Health and Safety Management Systems), up to 393%.This standard was not published until 2018, and the transitional period from BS EN OHS&S 18001 to ISO 45001 ended on 11 September 2021.The aim of the survey was to point out the growing trend and development of standards, especially in the field of safety management systems.

Characteristics of the ISO 45001:2018 Standard from the Point of View of the PDCA Cycle
The occupational health and safety management system brings several benefits to the organization.It is proof that the organization is interested in its employees, which is a positive signal for customers as well as for current and potential employees [8,17].For the organization, this means increasing productivity and work efficiency, improving corporate culture, increasing employee loyalty and satisfaction, improving working conditions and minimizing occupational accidents and diseases.At the same time, the organization proves that its products or services are implemented under defined working conditions in terms of health and safety.
In the current concept of safety, a holistic approach to addressing occupational safety and health means understanding occupational safety and health as a whole.This principle is strongly emphasized in all conceptual materials of international organizations.This approach also includes the comprehensive development of well-being at work, increasing the culture of work, strengthening economic incentives, and the social responsibility of employers.
The applied health and safety management system is based on the Plan-Do-Check-Act concept (PDCA) [18,19].The PDCA concept is an iterative process used by organization to achieve continual improvement [20][21][22][23].It can be applied to a management system, and to each of its individual elements, as follows [2,24]:  In Figure 3 it can be seen that, from the point of view of the new standard ISO 45001:2018, the structure of the occupational health and safety management system is at a high level.In Figure 3 it can be seen that, from the point of view of the new standard ISO 45001:2018, the structure of the occupational health and safety management system is at a high level.In Figure 3 it can be seen that, from the point of view of the new standard ISO 45001:2018, the structure of the occupational health and safety management system is at a high level.

Importance and Advantages of the Occupational Health and Safety Management System According to the ISO 45001:2018 Standard
The purpose of an OH&S management system is to provide a framework for managing OH&S risks and opportunities [26].The aim and intended outcomes of the OH&S management system are to prevent work-related injury and ill health of workers and to provide safe and healthy workplaces.Consequently, it is critically important for the organization to eliminate hazards and minimize OH&S risks by taking effective preventive and protective measures.When these measures are applied by the organization through its OH&S management system, they affect its OH&S performance.An OH&S management system can be more effective and efficient when taking early action to address opportunities for improvement and protective measurement.Implementing an OH&S management system conforming to this document enables an organization to manage its OH&S risks and improve its OH&S performance.An OH&S management system can assist an organization to fulfill its legal requirements and other requirements.
The main advantages of the new OH&S management system according to ISO 45001:2018 can include: Elimination of health and safety risks; Development of best practices in the field of occupational safety and health; Reduction in fatalities, accidents at work, and diseases in the workplace; Demonstration of leadership and commitment with regard to the OH&S management system; Creation and implementation of health and safety policy and goals; Monitoring and measurement supports supervisory management by providing key performance indicators (KPIs) in measuring the level of performance of the health and safety management system.
The aim of the OH&S management system certification, according to ISO 45001:2018, is to verify compliance with the requirements of the international standard ISO 45001, to introduce a systemic and process approach in the field of OH&S, and to introduce a system of continuous improvement in the field of OH&S.
The occupational health and safety management standard certification aims to ensure that the organization cares for and pays attention to the occupational health and safety management system in carrying out the overall activities of the certified organization [27].
As for employers, they can say after successful certification that: They objectively assessed the current state of the health and safety management system; They have expanded their business opportunities and increased their credibility; They have introduced continuous improvement; They have eliminated chaos and shortcomings in the field of health and safety.
As far as customers are concerned, after the introduction and certification of the health and safety management system, preconditions will be created for improvement in the areas, see Table 4.
Table 4. Areas benefiting from the implementation and certification of the health and safety management system according to ISO 45001:2018 from the customer's point of view [28].ISO 45001 sets out to provide a robust and effective set of processes for improving work safety in global supply chains and is also the world's first International Standard for occupational health and safety.For example, among the first organizations in the UK to successfully obtain certification for the ISO 45001:2018 standard are organizations CBRE, Colas Rail, EMCOR UK, Eurovia UK, Interserve, Morgan Sindall, OKI UK, OPG, Overbury, and Ringway Jacobs [29].
As for Slovakia, it is difficult to summarize how many organizations have implemented and certified STN EN ISO 45001:2019.The standard STN EN ISO 45001:2019 came into force in March 2019.The number of organizations that have the STN ISO 45001:2019 standard in place is in the hundreds.However, all large companies that have a significant role in the Slovak industry have the standard STN EN ISO 45001:2019 established and certified in accordance with applicable legislative requirements.

Occupational Health and Safety STN EN ISO 45001:2019 in the Context of Occupational Accidents in the Conditions of the Slovak Republic
Occupational health and safety is a key concern and responsibility of the state.The role of the state is to support the protection of employees at work; social justice; strengthen the functioning of the labor market; eliminate losses from accidents at work, occupational diseases, and industrial accidents; promote suitable working conditions; increase labor efficiency and productivity; and encourage market competitiveness with an impact on business prosperity and overall development of the country.
Occupational accidents and diseases have a detrimental effect on workers and equipment and on the quantity and quality of production [30].
ISO is designed to help organizations of all sizes and industries.It is this new international standard (ISO 45001) that is expected to reduce the number of accidents and illnesses in the workplace worldwide.As far as the Slovak Republic is concerned, these claims can be partially confirmed by the number of occupational accidents that occurred before the creation of the standard STN EN ISO 45001:2019 and which occurred only after the creation of the standard.Of course, the COVID-19 pandemic also had a potential impact on these statistics.Serious and fatal accidents have really occurred in workplaces (such as heavy industry, engineering, and automotive environments) where there is continuous production.Employees had to come to the workplace in person, and they had to be there in the number required by this type of work, so the COVID-19 pandemic had little effect on the total number of fatalities and serious accidents at work.
Table 5 shows the share of the main groups of resources in the total number of fatal accidents at work in organizations in the years 2010-2021.Table 6 shows the share of the main groups of resources in the total number of serious accidents at work in organizations in the years 2010-2021.Regarding the development of fatal and serious accidents at work, the tendency to reduce the number of these accidents is visible in Figure 4.As the standard STN EN ISO 45001:2019 came into force in Slovakia in March 2019, the trend in the number of fatal accidents and serious accidents is declining.

Conclusions
ISO 45001:2018 contains more requirements compared to the previous edition.At the same time, however, it provides more freedom in fulfilling them.The wording of the standard can be considered a step forward-it is clear, and it reflects the current situation in the business environment.Its structure is compatible with other management systems, in particular the ISO 9001:2015 quality management system and the ISO 14001:2015 environmental management system.All three management standards have the same chapter structure, which allows one to create an integrated management system of quality, environment, and health and safety.
The OH&SMS implementation helps the company in the process of structuring and organizing the OH&S management area, as well as in a better development of all the activities that are part of this area [32].ISO 45001 improves the effectiveness of work accident control by implementing a comprehensive OH&S management system [33,34].
The success of the OH&S management systems depends on leadership, commitment, and participation from all levels and functions of the organization; the allocation of the necessary health and safety resources, policies, and objectives; compliance with legal and other requirements; effective safety risk management; rigorous monitoring; evaluation of the performance of the health and safety management system; and the integration of this system into the business processes of the organization.
(a) Plan: determine and assess OH&S risks, OH&S opportunities, and other risks and other opportunities; establish OH&S objectives and processes necessary to deliver results in accordance with the organization's OH&S policy.(b) Do: implement the processes as planned.(c) Check: monitor and measure activities and processes with regard to the OH&S policy and OH&S objectives, and report the results.(d) Act: take actions to continually improve the OH&S performance to achieve the intended outcomes.
