What are the hazards of chemicals to the human body?

With the rapid development of the economy, the chemical industry is also constantly improving, and chemicals are widely used. The main hazards of hazardous chemicals are flammability, explosiveness, toxicity, harm, corrosion and environmental pollution. Especially now, people who are engaged in hazardous chemical work are very vulnerable to harm. So what are the hazards of chemicals to the human body? I believe everyone would like to know, let’s learn about the harm of chemicals to the human body.

Poisons can enter the body through the respiratory tract, digestive tract and skin. In industrial production, poisons mainly enter the body through the respiratory tract and skin. They can also enter through the digestive tract, but this is relatively minor.

Stimulate

Irritation means that the body has come into contact with the chemical quite seriously, usually to the skin, eyes and respiratory system.

skin

When certain chemicals come into contact with the skin, they can cause the skin's protective layer to fall off, causing the skin to become dry, rough, and painful. This condition is called dermatitis, and many chemicals can cause dermatitis.

Eye

Injuries caused by chemical contact with the eyes range from mild, temporary discomfort to permanent disability, and the severity of the injury depends on the dose of poisoning and how quickly first aid measures are taken.

Respiratory system

When chemical irritants in the form of mist, gas, or vapor come into contact with the upper respiratory system (nose and throat), they can cause a burning sensation. This is generally caused by soluble substances, such as ammonia, formaldehyde, sulfur dioxide, acids, and alkalis, which are easily absorbed by the moist surface of the nasopharynx. These chemicals must be handled with care, such as when spraying medications, to prevent inhalation of the vapors.

Combustion hazards of hazardous chemicals: Compressed gases and liquefied gases, flammable liquids, flammable solids, self-igniting items and items that are flammable when wet, oxidizers and organic peroxides, etc. may burn and cause fire accidents.

Explosion hazard of hazardous chemicals: In addition to explosives, compressed gases and liquefied gases, flammable liquids, flammable solids, self-igniting items and items that are flammable when wet, oxidizers and organic peroxides may all cause explosions.

Toxicity of hazardous chemicals: In addition to poisonous and infectious items, some substances in compressed and liquefied gases, flammable liquids, flammable solids, etc. can also cause poisoning.

What is mentioned above is the hazards of chemicals to the human body. People who are usually exposed to this kind of work must improve their protection awareness and strengthen personal protection. They must also be trained, strengthen popular science propaganda, popularize disaster reduction knowledge, and reduce damage to the greatest extent possible. People who are not engaged in hazardous chemicals must also have personal protection awareness.
