For the sustainable development of a country or even a city, industry has played an important and irreplaceable role. Steady development of the industry requires a large workforce, and for this reason, the industry is promoting local employment to promote economic development. If on the one hand the constant development of the industry has a positive impact on the territory, on the other it also has a negative impact: this is the "problem of accidents at work". Different types of industries, both heavy industry and light industry, including manufacturing, construction, energy, mining and so on, involve manual handling, large-scale manual or mechanical operations stairs. These processes produce different forms, categories and different levels of potential risk for workers. The problem of accidents at work has always been an obstacle to local development, the losses include the loss of working hours, related compensation and litigation, etc., it is a huge, unimaginable number. To this end, all over the world they are committed to studying the effective prevention of industrial accidents in order to prevent the occurrence of accidents at work. Over time, continuous research has led to significant results in the prevention of accidents at work. Institutions and managers have introduced and published different types of statements, guidelines, etc., with the aim of promoting the study results and industry-relevant data through these publications, with the aim of further improving the index of industrial safety.

Get an original essay And one of the topics, “Human Factors and Ergonomics,” is worth taking the time to understand its content, while the Health and Safety Executive, UK issued a bulletin in 2007 with the topic “Understanding Ergonomics at work", the bulletin headline has become a research topic of the Occupational Safety, Health and Environment degree course awarded by a prestigious university in the United Kingdom. The content of the heading is “Reduce injuries and illnesses and increase productivity by adapting the task to the worker”. With this topic there is room to discuss whether it is the ideal situation by adapting the task to the worker, whether it is really possible to reduce accidents and illnesses and increase productivity? Referring to “A Brief History of Human Factors and Ergonomics”, the first or basic concept of human factors and ergonomics is considered during the period 1939-1945 during World War II. Data shows that many human factors and ergonomic advances are due to the military's need. Before World War II, the machine, for example the fighter, was designed based on the concept of "design man to fit the machine" instead of "design the machine to fit man". With continued research and development over the previous decades, and as time has passed, it has evolved into a current topic: human factors and ergonomics. Nearly seventy years after World War II, the first topic of human factors and ergonomics originated. Many studies and research have been done and published, but there is still no concrete answer to the question: is it the ideal situation by adapting the task to the worker? Does it really reduce accidents and illnesses and increase productivity? Referring to the bulletin issued by the Health and Safety Executive, United Kingdom with the topic "Understanding ergonomics at work", it was described that ergonomics means a science dealing with the fit between people and work, aiming to maintain and improve health and safety usingergonomics. Considers the worker's capabilities and limitations, ensures that the tasks, equipment and working environment are suitable for the workers. Ergonomists consider the following aspects, evaluating the fit between worker and job. It includes: the scope of the work and the number of workers needed to complete the work; Is there any equipment needed for the job? Can any equipment to be used help the work or can the use of equipment reduce the workload? Any working methods and procedures designed for the job? Do all workers know and understand the work method and procedure? Or any other information needed for the job and has this information been provided to the workers? Is the physical environment, the working environment suitable for work? Such as extreme weather conditions, temperature and humidity aspects, sufficient lighting and is there any noise or vibration affecting workers? The social environment – ​​such as teamwork and supportive management, etc. The above criteria can help develop and maintain a safe and healthy working environment for workers and help establish a good work system. Additionally, ergonomists must also consider the physical aspect of the job by evaluating body size and shape; Do they have sufficient fitness and strength for the job? Consider workers' working posture and their senses such as sight, hearing and touch. Of course, regarding psychological aspects, it is also necessary to evaluate mental abilities, personality, knowledge and experience. Thanks to all these factors, it seems to satisfy the criteria of “adapting the task to the worker” and “the worker suitable for the task”. Considering the above concern of designing a comprehensive work program in order to make both the work fit for the workers and the workers fit for the work at the same time, this is the ideal situation. In Hong Kong, there are numerous regulations, codes of practice and guidance notes relevant to ergonomics but represented in different ways, such as the “Factories and Industrial Enterprises Regulations”, which state that all workers working on a construction site construction workers must complete a mandatory safety training course and hold a valid certificate, it also mentioned the requirement of medical examinations of people employed in some specific jobs and "Construction Site (Safety) Regulations", clearly stated the requirement of trained workers and competent to operate mechanical equipment, "Guidance Notes on Manual Handling Operations" and "Occupational Safety and Health (Display Screen Equipment) Regulations", published by the Occupational Safety and Health Branch - Department of work, Hong Kong, explains the various sections on manual handling operations and VDU equipment requirements in the Occupational Health and Safety Regulations and also covers aspects of hazard identification, risk assessment and risk control. It aims to guarantee the knowledge, experience and competence of the worker, making "the worker fit for work". Furthermore, regarding laws and regulations aimed at ensuring "the fit of work to workers", we have, for example, the "Guidance Notes on the Factories and Industrial Enterprises (Noise at Work) Regulation", in several parts of the "Construction Site (Safety) Regulations". ventilation, lighting and physical cleanliness requirements also on construction sites and workplaces. In the example above, we can see that most of the above regulations and guidance notes represent ergonomics, but in a different scheme notes focus on ergonomics at work? If you examine the cases of.
