What are the classifications of burns to the human body

This condition may be caused by a neurological disorder. It is best to go to the relevant departments of regular hospitals**, early**early**; Usually strengthen physical exercise, improve one's own resistance, avoid tiredness, cold, cold, pay attention to diet, eat more fresh fruits and vegetables.

A migratory burning sensation all over the body is the cause of Ha.

There are six categories of hazardous chemical accidents, namely hazardous chemical fire accidents, hazardous chemical accidents, hazardous chemical poisoning and suffocation accidents, hazardous chemical burn accidents, hazardous chemical spillage accidents and other hazardous chemical accidents.

In the book "Selected Cases of Serious Accidents of Hazardous Chemicals", it is introduced in detail the major accidents of hazardous chemicals production, storage of hazardous chemicals, transportation of hazardous chemicals, emergency rescue of major accidents of hazardous chemicals and other major accidents of hazardous chemicals, which should be paid attention to in the production of hazardous chemicals.

Hazardous chemical accidents in the enterprise, around is still very common, Jinchuan Group launched the Jinchuan model, so that enterprises get a zero-fault system architecture, do not believe the above picture to see, from China and Hong Kong Jinbang. Thank you, useful, please adopt. Thank you.

What is wrong with a strong burning sensation in the front chest and back, low body temperature, and no sweating?

There was a sore and burning bone on the left.

There are several modes of dust classification.

12. Classification of dust.

1) Divided according to the nature of the dust.

According to the different properties of dust, it can be divided into inorganic dust, organic dust and mixed dust.

a Inorganic dust. It includes:

Mineral dusts, such as quartz, asbestos, etc.;

metal inorganic dust, such as iron, aluminum, tin, etc.;

Artificial inorganic dust, such as cement, synthetic diamond, etc.

b Organic dust. It includes:

Animal dust, such as hair, feathers, silk, bones, etc.;

Plant-based dusts, such as cotton, linen, grains, gowns, etc.;

Artificial organic dust, such as explosives, organic dyes, etc.

c. Mixed dust, that is, the above-mentioned types of dust are mixed.

2) Divided according to the size and optical characteristics of dust particles.

According to the size and optical properties of dust particles, they can be divided into visible dust, microscope dust and ultra-microscope dust.

a Visible dust: refers to dust with a particle size greater than 10 m (microns) and visible to the naked eye.

b Microscope dust: It refers to dust with a particle size of 10 m—visible with an optical microscope.

c Ultramicroscope dust refers to dust with a particle size smaller than that visible under the electron microscope.

Dust with a particle size smaller than almost no land in still air and is easy to diffuse.

Working in the dust for a long time and improper respiratory protection can easily cause fibrosis of lung tissues, which is the so-called pneumoconiosis.

The way to clean the dust: now masks must implement the GB2626-2006 standard. The grades of dust masks are divided into three grades: KN100, KN95, and KN90. Among them, KN100 can achieve nearly 100% (more) protection effect against ultrafine dust.

The protective effect of dust masks depends on 2 aspects. One is the filtration efficiency of the filter cotton. The second is how tightly the mask is combined with the face.

The second is that the mask must be divided into large and small sizes, and the fitting effect of the mask and the face varies from person to person.

The way to clean dust: the scientific selection of dust masks certified by GB2626-2006 standards can help prevent lung damage.

1. Choose a duplex half mask type. Disposable masks are not suitable for long-term protection due to their high air leakage rate.

2. Choose KN100 dustproof filter cotton for use. A low rate of protection will lead to physical injury.

3. It is more comfortable to choose silicone material. It is suitable for long-term wear and is not easy to cause allergic reactions. Masks with high rigidity are prone to facial indentation.

4. Masks are divided into large and small sizes, which is extremely important. Don't buy masks that are called generic models. Prone to air leakage.

5. There are two types of masks that cover the mouth and nose, covering the mouth, nose and chin, and it is recommended to use the latter, which is relatively comfortable.

6. It is recommended to choose a breathing mask. Some masks are designed with double filters, and the filters are double-sided, so that the masks are relatively easy to breathe.

It is also usually accompanied by nausea, dizziness, severe limb detachment, erosion.

Generally, there will be a burning sensation, and there may be some tingling, dizziness, nausea, vomiting, diarrhea, fatigue, etc., which can be fatal if it is exposed to large doses.

Long-term effects include carcinogenic, refractory ulcers, radiation gastroenteritis, cataracts, and increased teratogenicity in offspring.

The super-large dose fainted and died within minutes.

It is said that the nuclear ** can even see its own bones in visual conditions before it dies :d
