What are the hazards of chemical products 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, and can also enter the body through the digestive tract, but they are less important.
Irritation means that the body has been in serious contact with the chemical, and the areas that are generally irritated are the skin, eyes and respiratory system.
When certain chemical products come into contact with the skin, the chemical products can peel off the protective layer of the skin, causing dry, rough, and painful skin. This condition is called dermatitis. Many chemical products can cause dermatitis.
Injuries from chemical products and eye contact can range from mild, temporary discomfort to permanent disability. The severity of the injury depends on the dose of poisoning and how quickly first aid measures are taken.
Misty, gaseous, vaporous chemical irritants that come into contact with the upper respiratory system (nose and throat) can cause a burning sensation, which is generally caused by soluble substances such as ammonia, formaldehyde, sulfur dioxide, acids, and alkalis, which are easily Absorbed by the moist surfaces of the nasopharynx. Handling of these chemical products must be handled with care, such as when spraying medicines, to prevent inhalation of these vapors.
Combustion hazard of hazardous chemical products: Compressed gas and liquefied gas, flammable liquids, flammable solids, spontaneous combustion and wet flammable materials, oxidants and organic peroxides may all burn and cause fire accidents.
Explosion hazard of hazardous chemical products: In addition to explosives, compressed and liquefied gases, flammable liquids, flammable solids, spontaneous combustion and wet flammables, oxidants and organic peroxides may cause explosions.
Toxicity of hazardous chemical products: In addition to poisons and infectious substances, some substances in compressed and liquefied gases, flammable liquids, and flammable solids can also cause poisoning.
