What occasions are lightweight semi enclosed chemical protective clothing suitable for?

Lightweight semi-enclosed chemical protective clothing is usually used in steel mills, petrochemical plants, telecommunications, aviation, emergency medical departments, etc., and is mainly used in occasions with low protection level requirements. If you want to enter the toxic gas environment for operation, you should also be equipped with a combination of respiratory protection equipment such as full-face filtering gas masks or positive pressure air respirators, so that you can safely operate in a toxic gas environment. If the ambient gas contains highly toxic or corrosive media, in order to avoid unnecessary **, it is good to equip heavy-duty fully enclosed chemical protective clothing, after all, the sealing effect of semi-closed chemical protective clothing is not so good.

This enables workers to work safely and effectively in environments such as acids, alkalis, gaseous, liquid, solid chemicals, and corrosive dusts. But there is one caveat.

If you want to enter the toxic gas environment for operation, you should also be equipped with a combination of respiratory protection equipment such as full-face filtering gas masks or positive pressure air respirators, so that you can safely operate in a toxic gas environment.

Huatong firefighting first-class chemical protection clothing is used at the scene of fire accidents of chemical dangerous substances or corrosive materials, as well as at the scene of toxic and harmful gas accidents.

Huatong fire protection secondary chemical protection clothing is a full-body protective clothing used for dangerous place operations (except for the face).

Huatong fire-fighting special chemical protective clothing has more perfect performance than general products, has better protection function than general products, has excellent protection effect against more than 400 kinds of chemical substances, and can be applied to more demanding places.

Fully sealed chemical protective clothing is a protective clothing worn by personnel when entering the scene of a fire or accident of chemical dangerous substances or corrosive substances, as well as toxic and harmful gases or accident scenes, looking for fire sources or accident points, rescuing victims, and carrying out fire fighting and emergency rescue.

Fully enclosed chemical protective clothing is the one with the best safety performance in chemical protective clothing, which corresponds to semi-enclosed chemical protective clothing, and the protection level generally belongs to class A or B protection. Fully enclosed chemical protective suits must be used at the same time with air respirators or long-tube respirators, most of which are used to defend against toxic and harmful gases and liquids that are harmful to the human body and breathing.

Permeability is a very important indicator for choosing a fully enclosed chemical protective suit. The same material will exhibit different permeation resistance to different types of chemicals, and even different concentrations of the same chemical. Therefore, when choosing a fully enclosed chemical protective suit, it should be selected after referring to the data of the anti-permeation performance of the fabric against different chemicals as much as possible.

Hello.

First, the role. The human chemical protective suit is suitable for emergency rescue and disaster relief and accident handling in an environment filled with toxic and strong corrosive media, and is used to protect the respiratory and circulatory system of staff and the human body from toxic and strong corrosive media.

The chemical protective suit is a new type of human air breathing equipment, which has the characteristics of light weight, easy dressing, free suction, flexible rotation, safety and reliability, strong adaptability, and corrosion resistance.

Second, performance. The fabric of the chemical protective clothing is made of double-sided butyl glue and cotton silk in the middle, and the size of the chemical protective clothing is a single specification, which is suitable for people of all body types with a height of meters.

The chemical protective suit adopts a positive pressure sealing structure. The gas mask maintains a certain body pressure in the room, and the excess gas is discharged from the body through the exhaust valve, and the positive pressure working state is maintained. The resistance of the exhaust valve is not greater than 680 pa at a vent flow rate of 30 litres.

The ventilation flow rate is 150 litres and not more than 1050 pa at the fraction.

Chemical protective suits can be used in environments with hydrofluoric acid-containing media. However, it must be used in conjunction with a portable air respirator, which should not exceed one hour each time and should be washed off immediately after use.

3. Preparation of chemical protective clothing before use:

According to the medium to be protected, the appropriate protective and air supply devices are selected.

According to the user's height and the size of the hands and feet, suitable protective boots and protective gloves are selected, and installed on the protective clothing to clamp and seal tightly.

Check whether the connection of each part is correct, whether the seal is reliable, and whether the lens is aged, discolored or damaged.

Check whether the gas supply device is in normal operation and check it according to the terms specified in the instruction manual of the air supply device it is equipped with.

Hope it helps.

First, the structure is different, the fully enclosed chemical protective suit adopts a one-piece built-in respirator design, and the light chemical protective suit adopts a split design.

Second, the thickness is different, the thickness of heavy chemical protective clothing is generally above, and the thickness of light chemical protective clothing is mostly lower than this thickness.

Third, the zipper is different, the heavy-duty chemical protective clothing uses an airtight zipper, and the light-duty chemical protective clothing uses a watertight zipper.

Chemical protective clothing is divided into many models, which are classified according to the level of protection, and the heavier the level, the stronger the protection function, TDAF001

Some customers don't know which one is more suitable for them when buying chemical protection clothing? I don't know what kind of chemical protective clothing I should use in this situation, is it heavy-duty? Or use a lightweight one? I don't know the difference between them, and I don't know how to choose.

Lightweight chemical protective clothing is mainly effective protection against chemical solvents, dust particles and viruses.

It is mainly used in medical and health care, chemical plant operations, spraying industry, etc. Heavy chemical protective clothing is also known as Class A chemical protective clothing, airtight chemical protective clothing or fully enclosed chemical protective clothing. It can effectively protect against the invasion of gambling.

It is often used in fire rescue, chemical spill rescue and other occasions. So what is the difference between a light chemical protective suit and a heavy chemical protective suit? We analyze it from the following aspects:

Materials, colours, sealing, flexibility and comfort and where to go.

Let's talk about the difference between materials and materials: the material of light chemical protective clothing is lighter than that of heavy chemical protective clothing, light chemical protective clothing is mostly coated with neoprene, and heavy chemical protective clothing generally uses PVC. The difference in color is that the color of the light chemical protective suit is orange-red, and the color of the heavy duty is yellow.

In terms of the airtightness of protective clothing, light chemical protective clothing is less airtight than heavy chemical protective clothing. Because the heavy-duty chemical protective clothing wraps the whole person, the zipper adopts an airtight zipper, which further ensures the airtightness of the chemical protective clothing, while the light chemical protective clothing generally protects the entire body, and the face needs to be equipped with a separate gas mask to protect against toxic substances.

Because the heavy-duty chemical protective clothing is a fully enclosed form, it is relatively cumbersome, so the flexibility is not light, the light chemical protective clothing is lightweight, easy to wear, and more flexible operation. Lightweight chemical protective clothing is only suitable for use in steel mills, petrochemical plants, telecommunications, aviation, emergency medical departments, chemical plants, and other sites where there are no toxic or harmful gases, while heavy chemical protective clothing is more suitable for on-site operations with dangerous chemicals or corrosive substances.
