It was known in the twentieth century that there were knowledge gaps in the workplace when it came to health and safety. As a result, research activities were coordinated. In the United States, NIOSH was a key player in early efforts, followed by OSHA, which resulted in the creation of a variety of programs to address health and safety problems via regulation and promotion. This includes the formation of special committees to deal with certain topics.

Step-by-step explanation

I recently finished an OBHR course that introduces readers to the ideas of occupational health and safety. Theories of Occupational Health and Safety,  History of Occupational Health and Safety,  Occupational Hazards, Occupational Diseases, and Reforms in OSH were the five components of the course.
I learned about the history of OSH, which was created by governments after WWII with the goal of ensuring worker safety. It has evolved throughout time in response to changing demands, such as changes in engineering design or the entrance of new chemicals into the workplace.
I learned about OSH's foundations while researching its history. The National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA) were established as a result of this (OSHA). The National Institute of Occupational Safety and Health (NIOSH) was established by the United States Congress in 1970 to undertake research on workplace risks and safeguard employees' health. Congress created OSHA in 1971 to supervise the implementation of occupational health regulations. They were both created to assist assure safe working conditions, prevent work-related accidents and illnesses, undertake work-related sickness research, and give health benefits training to workers. The advancement of OSH is the responsibility of these two agencies.
The act of prevention is a core concept that is vital to grasp based on the historical development of OSH. Occupational illnesses grew increasingly widespread in the late 19th and early 20th centuries as a result of technical advancements and changes in existing work conditions. Prevention was created to solve the issues that employees encountered at the time, but it is still useful now since it improves safety. This was in reaction to the fact that the majority of work-related accidents and illnesses may be avoided with proper workplace safety measures. It is important to remember that this is a long-term process that has lasted many decades.
It was known in the twentieth century that there were knowledge gaps in the workplace when it came to health and safety. As a result, research activities were coordinated. In the United States, NIOSH was a key player in early efforts, followed by OSHA, which resulted in the creation of a variety of programs to address health and safety problems via regulation and promotion. This includes the formation of special committees to deal with certain topics.
Theories were studied in the second half of this course. Occupational health and safety theories are divided into two categories: objective and subjective features. Physical features such as exposure to labor risks and biological dangers are examples of objective qualities. Subjective traits are those that aren't objective in nature and instead represent the perspectives and experiences of workers, employers, and society as a whole.
In theory, three key parts characterize occupational health and safety: contributing causes (acute or chronic), circumstances (physical or social), and behaviors or actions (as described earlier). These three components may be used to categorize occupational health and safety theories.
Occupational illnesses and dangers were among the other important subjects addressed in this course. I learnt about the significance of these two ideas in occupational safety and health, as well as their definitions and attributes. I also learnt about cancer, cardiovascular illness, mental issues, and musculoskeletal ailments, among other diseases (MSDs). I was able to learn not only about various sorts of illnesses, but also about how they were created. Finally, this course covered how to manage workplace risks via preventative measures or early detection and treatment.
I discovered how vital occupational health and safety is in today's workplace. I was able to recognize the many forms of work-related problems that might arise, particularly those that are physical or biological in nature. I also had the opportunity to learn about how we can prevent avoidable injuries and illnesses by controlling these types of conditions and ensuring workers receive appropriate preventative training. Finally, I learned how, even in the twenty-first century workplace, occupational health and safety is critical because there are still gaps in knowledge about diseases, conditions, and hazards.
