Occupational Disease Hazard Factors refers to various harmful chemical, physical, biological factors that exist in occupational activities and other occupational harmful factors that occur during the operation. In addition to directly affecting the skin, mucous membranes and eyes, causing burns and allergies, most occupational disease hazard factors can only cause harm to human health if they enter the human body. So what are the ways for occupational disease hazard factors to invade the human body?
Hidden factors for occupational disease hazards that exist in the production environment through the respiratory tract can enter the human body through the respiratory tract. Occupational disease hazard factors entering through the respiratory tract are directly entered into the blood circulation through alveolar . The toxic effect is great and the toxic effect occurs quickly. This is also the most common and dangerous way for occupational disease hazard factors to enter the human body, such as various dusts, CO, benzene vapors, etc.
02 Entering from the skin
Many occupational disease hazard factors (including gaseous and liquid) can enter the human body through the complete skin. When skin damage is caused by skin diseases, trauma and other reasons, poisons are more likely to enter through the damaged skin. Poisons entering the human body through the skin are often easily neglected. Therefore, the entry of the poison into the human body through the skin is an important reason for occupational poisoning. The range of poisons that can enter the human body through the skin is relatively wide, such as aniline , dimethylformamide , organophosphorus , etc.
03 Entering
In the production process, occupational disease hazard factors are generally not easy to enter the human body through the digestive tract. However, if the poison is easily consumed due to accidents or personal hygiene, the poison is easily consumed by contaminated hands, clothing, and food. If the workers in the battery factory do not pay attention to personal hygiene, it is very easy to intake lead through the digestive tract and cause lead poisoning .
With the inevitable exposure to various occupational disease hazard factors, workers should pay more attention to strengthening protection, take good precautions, and avoid occupational disease hazard factors entering the body quietly.
2. Principles of prevention of occupational diseases
01First-level prevention
Mainly start, so that workers should not be exposed to occupational harmful factors as much as possible, or control all harmful factors in the workplace within the limits of the hygiene standards.
02 Secondary prevention
Implement health monitoring for working workers, early detection of occupational damage, timely handling, effective treatment, and prevent further development of the disease.
03Trial prevention
Active treatment of patients who have already suffered from occupational diseases to promote health. The relationship between the third-level prevention is: highlighting first-level prevention, strengthening second-level prevention, and doing a good job in third-level prevention.
3. Basic measures for implementing third-level prevention of occupational diseases
01Implement labor health supervision
Including preventive and regular health supervision, as well as accident handling. The "three simultaneous" acceptance of sanitary protection facilities for new, expanded and renovated projects is its important content;
02 Reduce the concentration (intensity) of harmful factors
Common sanitary technology measures include improving the process, preventing the dissipation of harmful factors, promoting the use of low-toxic and non-toxic materials or technologies, and configuring personal protective supplies , ventilation and dust prevention, etc.;
03 Occupational health check
It has become a common measure: occupational inspection before taking up the job, occupational inspection and off-the-job occupational inspection.
