1.1 Introduction
Occupational safety and health (OSH) refers to the science and practice of preventing work-related injuries, illnesses, and accidents while promoting the physical, mental, and social well-being of employees in the workplace. It encompasses the development and implementation of policies, procedures, and control measures aimed at ensuring safe and healthy working conditions for all categories of workers. According to the International Labour Organization and the World Health Organization, occupational safety and health is concerned with promoting and maintaining the highest degree of physical, mental, and social well-being of workers in every occupation by preventing health impairments arising from workplace conditions (International Labour Organization & World Health Organization, 2022). The workplace serves as a major environment where employees spend a significant portion of their lives performing tasks that contribute to organizational productivity and economic development. However, many workplaces expose employees to various occupational hazards that threaten their health, safety, and overall well-being (Alli, 2018).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the aim and objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
Historically, occupational safety and health hazards among employees is closely associated with the development of human labour and industrial activities. From the earliest civilizations, people engaged in farming, mining, construction, metalworking, and other forms of manual labour that exposed them to numerous workplace hazards. According to Alli (2018), early workers experienced injuries and occupational illnesses because little attention was given to workplace safety, and most employers focused primarily on increasing production rather than protecting workers' health. During this period, accidents and diseases resulting from hazardous work environments were generally regarded as unavoidable consequences of employment.
Occupational safety and health (OSH) has become one of the most significant areas of concern in modern organizations because employees constitute the most valuable resource for achieving organizational goals. Alli (2018) reported that, occupational safety and health involves the promotion and maintenance of the highest level of physical, mental, and social well-being of employees through the prevention of workplace injuries, illnesses, and accidents. The concept extends beyond preventing accidents to creating a work environment where employees can perform their duties without unnecessary exposure to hazards that may impair their health or reduce their productivity. As organizations continue to expand their operations and adopt new technologies, ensuring safe and healthy working conditions has become an indispensable aspect of sustainable organizational management.
Goetsch (2020) stated that, occupational hazards are workplace conditions or situations capable of causing injury, disease, property damage, or even death if appropriate preventive measures are not implemented. These hazards exist in virtually every occupation, although their nature and intensity vary depending on the type of work performed. Physical hazards such as excessive noise, heat, vibration, poor lighting, and radiation are common in industrial settings, while chemical hazards arise from exposure to toxic substances, gases, fumes, solvents, and dust particles. Biological hazards include bacteria, viruses, fungi, and other microorganisms that pose health risks, particularly in healthcare facilities and laboratories.
Hughes and Ferrett (2020) asserted that occupational safety and health management is essential because it minimizes workplace accidents while improving employee morale, operational efficiency, and organizational performance. A well-established safety management system enables organizations to identify hazards, assess risks, implement preventive measures, and continuously monitor workplace conditions. Effective safety management also promotes compliance with occupational regulations, enhances employee confidence, and reduces costs associated with workplace injuries, compensation claims, equipment damage, and production interruptions.
Similarly, the International Labour Organization (2023) reported that occupational accidents and work-related diseases remain among the leading causes of disability and death globally, affecting millions of employees every year. The organization further stated that workplace injuries and illnesses impose enormous economic costs on employers and national economies through lost productivity, healthcare expenses, compensation payments, and reduced labour efficiency.
In the same vein, the World Health Organization (2022) affirmed that a healthy workplace is one in which employers and employees collaborate to promote safety, health, and overall well-being through effective risk management and continuous improvement of working conditions. Occupational health therefore extends beyond physical protection to include mental health promotion, stress management, employee welfare, and the prevention of occupational diseases. Relatedly, Cooper (2018) asserted that organizational safety culture plays a crucial role in determining employees' attitudes toward workplace safety. A positive safety culture promotes compliance with established procedures, encourages hazard reporting without fear of victimization, and fosters shared responsibility for accident prevention.
This study is set against the backdrop of increasing concerns over occupational safety and health hazards among employees, the persistent occurrence of workplace accidents and work-related illnesses despite existing safety regulations, and the need to generate empirical evidence that will support the development of effective strategies for improving workplace safety, protecting employee well-being, and enhancing organizational productivity.
1.3 Statement of Problems
Investigation revealed that occupational safety and health hazards remain a major challenge confronting employees across different sectors of the economy despite growing awareness of workplace safety and the existence of occupational health regulations (International Labour Organization, 2023).
Furthermore, many organizations have introduced occupational safety policies, employee training programmes, hazard control measures, and the provision of personal protective equipment. Nevertheless, workplace accidents and unsafe practices continue to occur due to inadequate enforcement of safety regulations, poor safety culture, insufficient risk assessment, and management's limited commitment to occupational safety (Goetsch, 2020). It is against this backdrop that this study seeks to examine occupational safety and health hazards among employees.
1.4 Aim and Objectives of Study
The aim of this study is to examine occupational safety and health hazards among employees. The specific objectives of this research are to:
- Identify the occupational safety and health hazards faced by employees.

Furthermore, the study will provide occupational health and safety officers with relevant information that can support the planning and implementation of effective safety programmes. It will also contribute to safer working environments through the findings presented.
Lastly, the research will serve as useful reference material for government agencies responsible for monitoring compliance with occupational safety and health regulations.
1.8 Scope of Study
This study focuses on occupational safety and health hazards among employees using the Lagos State Water Corporation, Lagos State, as the case study.
The study covers the common workplace hazards faced by employees, the causes of these hazards, their effects on employee performance and well-being, the effectiveness of existing safety measures, and possible strategies for improving occupational safety and health within the organization.
1.9 Limitations of the Study
The study was limited to employees of the Lagos State Water Corporation, Lagos State, because it was not possible to include every organization in Nigeria. The findings were therefore based on information obtained from the selected respondents within the organization.
