Chemical reagents in the end how harmful to the human body?

With the development of our science and technology, we need to continue to learn chemical knowledge, in the process of learning chemical knowledge will certainly be more or less to come into contact with, different reagents will cause different degrees of damage to different parts of our body. Let's go together to understand the awesome of chemical reagents.

For example, concentrated sulfuric acid, when you use it, you must be careful not to let it drip on your skin, otherwise its oxidizing property is too strong, it will make your skin hurt, it will make your skin dry and peel off, and it will also cause pain. There are also some strong oxidizing drugs that can burn your skin, so be safe, especially when doing some chemical experiments.

For example, dichloromethane drops on the gloves, the hand will feel cooler after and there is the feeling of being burned by the fire, it also has an anemone-like flavor. Ethyl acetate has a tangy sweet fruit and chloroform has a special sweet flavor. All reagents need to fan the flavor of the hand smell, can not use the nose directly smell, easy to poison, resulting in respiratory diseases.

Some chemicals may cause allergic symptoms, of course, may not be allergic symptoms at first, but always exposed to the air, will cause different parts of the body allergic phenomenon. Symptoms such as redness, swelling and itching appear. Even some chemical reagents can cause a person to suffocate and lose their life directly.

Any chemical reagent reagent often a large number of contact will bring the human body do not need to degree of injury, so we have to pay attention to experimental safety, we have to use different safety measures according to different reagents. Protect their own safety.

In short, we generally latex gloves, plastic gloves, eye protection, safety clothing, ventilation kitchen and other simple safety equipment. We can not ignore these chemicals, they are extremely harmful. To love their lives, safety first.
