The harm of electroplating production to the human body and how to prevent it in daily diet

Dust hazards: A large amount of dust will be generated during the operation, which will bring serious occupational hazards to workers. Risk of electric shock:

Human contact with high-voltage and low-voltage power sources may cause electric shock** accidents. Other hazards: In addition to the main hazards mentioned above, there may also be noise hazards, mechanical injuries and lifting injuries in electroplating production.

The effects of electroplating on the body are not achieved overnight, but are a long-term accumulation process, which is mainly divided into the following three categories:

1. Dust hazards: A large amount of dust may contain silicon, chromium, aluminum, iron, copper and linen will be produced during the operation, which will bring serious occupational hazards to workers. Most organic solvents are toxic, trichloroethylene poisoning can cause rash, fainting, high fever, lymphoma, and finally cause a variety of complications, until **ulcer, liver and kidney failure and death; Benzene poisoning mainly affects the hematopoietic function of the human body, causing leukopenia in mild cases, aplastic anemia in severe cases, and finally leukemia; Carbon tetrachloride can cause serious damage to the liver and kidneys.

In addition, electrochrome plating will emit a large amount of chromium mist, chromium compounds can cause ulcers, anemia, nephritis and neuritis and other diseases, and have the effect of carcinogenic and inducing gene mutations.

2. Risk of electric shock: human contact with high-voltage and low-voltage power sources may cause electric shock accidents. Many electrical equipment are used in electroplating production, such as polishing machines, rolling machines, rectifier power supplies, cranes, centrifugal dryers, electric ovens, electric heaters, filters, barrel plating machines and sewage treatment equipment, etc., and their input voltages are generally very high.

In addition, the working site of the electroplating workshop is damp and the equipment is susceptible to corrosion, so in the process of use and maintenance, if the equipment is not operating normally, the protective measures are not effective or the operation is wrong, it is easy to cause electric shock accidents.

3. Other hazards: In addition to the above main hazards, there may also be noise hazards (such as ultrasonic cleaning, compressed air drying, etc.), mechanical injuries and lifting injuries in electroplating production. Take cyanide as an example, cyanide is one of the commonly used chemical raw materials in electroplating, which is very easily absorbed by the human body and can enter the human body through the mouth, respiratory tract or healthy **.

Cyanide enters the stomach under the dissociation of gastric acid, can be immediately hydrolyzed into cyanogenic acid and absorbed, after this substance enters the blood circulation, the fe3 of cytochrome oxidase in the blood combines with cyanide to generate cyanide iron cyanide cytochrome oxidase, loses the ability to transfer electrons, interrupts the respiratory chain, and the cell suffocates and dies. Due to the large solubility of cyanide in lipids, the central nervous system is the first to be harmed, especially the respiratory center is more sensitive.

Electroplating is the process of using the principle of electrolysis to coat a thin layer of other metals or alloys on some metal surfaces, and it is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, so as to prevent metal oxidation (such as rust), improve wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics. Many coins also have electroplated outer layers.

Electroplating emissions will cause changes in the nature of the land, which will increase the number of substances harmful to our body among the crops that are grown on the land that users eat, and these diseases will follow after these substances are eaten, and the environmental pollution will be serious, which will seriously endanger the survival of users.

The harm caused by the electroplating plant is not only an environmental problem, but also a considerable harm to the human body. The chemical factors in the electroplating production process include production toxicants (such as chromium, cyanide, hydrochloric acid, hydrogen sulfide, nitrogen oxides, acid mist, caustic soda, ammonia, organic solvents and synthetic additives). Physical factors include production dust (such as polishing dust, organic dust, etc.), abnormal environmental conditions (such as high temperature, high humidity, low temperature), noise, vibration, etc.

This is special work, and the poor environment and poor protection cause great harm to employees, even life-threatening. Air pollution and chemical volatilization can damage the respiratory system and eyes, etc.; Some chemicals are very toxic and should not be in contact with ** to avoid injury and poisoning. If you are engaged in this work, you must look at its working environment and safety protection measures; It is also necessary to strengthen the awareness of safe production and self-protection.
