[0002] Occupational health studies the health issues of humans in the process of engaging in various occupational labor. It aims to protect the health of employees from harmful factors during their occupational activities, including the impact of the working environment on the health of workers and the countermeasures to prevent occupational hazards. Only by creating reasonable working conditions can all people engaged in labor maintain physical, mental, social adaptability and other aspects of health. Only by preventing occupational diseases and occupation-related diseases can we reduce absenteeism due to illness and injury and improve labor productivity. Therefore, occupational health actually refers to the prevention of damage or disease caused by occupational hazards in various jobs, which belongs to the category of preventive medicine.
