Feed mill laboratory technicians pay attention to various deadly killers in the prevention laboratory
As a laboratory analysis of the testing organization, the staff often helps others check the safety of the product, but often ignores their own personal safety. There are many dangers in the laboratory. In addition to the hazards of chemicals that are often mentioned, these people are very careful in the experiment, and some of the damage comes quickly, obviously (a drop of acid drops down the new pants to burn a hole or redness on the hands). But there are no other hazards. Everyone is more invisible. It is generally not easy to find. I hope everyone can discuss it and do a good job of protection. After all, the body is the capital of revolution and the foundation of happiness.
In the laboratory, in addition to various testing instruments ICP, AA, GC-MS, infrared, ultraviolet, etc., there are auxiliary equipment air compressors, exhaust fans, etc., now the instrument is also connected to computers, printers, copiers, fax machines and so on. The equipment in the lab will be counted for a while. The noise, electromagnetic radiation, dust and ozone generated by these instruments have become the killers of our health.
Noise: The direct harm of noise to the human body is manifested in: destroying the human nerves, causing sputum to cause blood vessels, accelerating the metabolism of hair cells, thereby accelerating the arrival of aging. In clinical diagnosis: the external manifestation of the patient is that the whole person is in a bad mood, irritability and loud voice; the most common symptoms are tinnitus, earache, hearing loss, dizziness, headache and noise deafness. The noise is caused by sensorineural nerve damage and hair cell damage, which is difficult to repair. There is no specific drug to treat this damage. Some restorative treatments can be taken depending on the situation, such as avoiding noise environment, taking vitamins, and doing some aerobic exercise (climbing, running, etc.). But these treatments have had little effect. Therefore, the focus of noise disease is prevention, control of the source of noise sickness, and prevention. From a psychological point of view, noise first causes poor sleep, inability to concentrate, memory loss and other psychological symptoms, and then lead to mood disorders, emotional instability, and even reduced tolerance, temper, and finally produce high blood pressure, ulcers, diabetes Waiting for a series of diseases. The probability of noise causing psychosomatic diseases is quite large, and the treatment is difficult, and it takes a relatively long recovery period, which brings great trouble to people's daily life and work.
Electromagnetic radiation: Excessive electromagnetic radiation can cause excessive tension, neurasthenia, insomnia, lack of concentration, memory loss, slow response, headache, dizziness, multiple dreams, irritability, loss of appetite, abnormal blood pressure, decreased white blood cells, etc. And too much electromagnetic radiation may affect people's fertility.
Dust: The printer is the main source of office dust and meager profit. In a closed office space, the amount of particles in the air is five times higher when the printer is working than when it is not working. In addition, the printer is more likely to emit dust and particles when it has just replaced a new ink cartridge and printed a large amount of toner-consuming documents such as charts or images. Extremely small particles have a great influence on the human body, and they can effectively penetrate into the lungs of the human body, causing serious health hazards. These tiny particles are as small as the particles emitted by cigarettes, and when they penetrate deep into the human lungs, they cause the same harm as cigarettes.
Ozone: The greatest threat to health of electrical equipment is not electromagnetic radiation, but ozone, which consumes oxygen in the air. If the ventilation is not good, the ozone will compete with the human lung for limited oxygen, which will deteriorate the air quality. In this "contention", people are at a disadvantage, so they are prone to dizziness, nausea and so on. Ozone is a gas with a strong pungent odor. In addition to causing cancer, ozone can also irritate the respiratory tract of people, causing respiratory irritation such as cough and bronchitis. In addition, ozone can also threaten the human nervous system, causing dizziness, headache, nausea, decreased vision, memory loss and other issues, destroying human immunity, and easily aging, and human skin is prone to dark spots. If the pregnant woman is in an environment with high ozone concentration for a long time, fetal malformation may also occur. Mothers should stay away from copiers and computers as much as possible because they are the main source of ozone.
Treatment method: 1. To ensure the fresh air volume in the office environment, dilute harmful gases. If possible, open the window as much as possible. Don't care too much about the temperature. 2. Pay attention to the cleanliness in the office environment and clean it in time. You can raise some flowers to improve the air quality. Pregnant women should try to stay away from computers, copiers, or computers using LCD screens, and conditionally wear radiation protection suits. 4. If you have the conditions to go out and take a breath of fresh air, just take a shower for your lungs. 4. All kinds of instruments should be well maintained, so the noise generated will be small, and other damage will be less. 5. Some instruments can be opened separately, preferably in the next room. Such as auxiliary equipment such as air compressors.
