Common sense of wearing protective clothing 1. How to wear protective clothing correctly

We must ensure the applicability of chemical protective clothing before we are ready to wear it, that is, whether the protective clothing is in good condition. Visually check whether the appearance of protective clothing is polluted, whether the seams are cracked and whether the clothes are damaged. For air-tight protective clothing, it is necessary to use a special air-tightness detector to carry out air-tightness testing on a regular basis (once every six months) so that the protective clothing can play a role in emergency wear. It is very important to check before wearing. If judged only by experience, it is considered as safe equipment, but it is actually unsafe and may cause serious injury accidents. Before wearing protective clothing correctly, please ensure that the size of protective clothing is suitable for you. Too large or too small will cause inconvenience or accidental damage and tear in the working process. Take away sharp objects, unnecessary keys, knives, pens, etc. In order to avoid damage to protective clothing at work.

Choosing a dressing room is an ideal place to change clothes. If not, it should be done in a relatively pollution-free environment. In case of emergency rescue, the clothes should be worn in cold areas. Other necessary auxiliary systems Before using chemical protective clothing, ensure that other necessary auxiliary systems (such as gas supply equipment and decontamination equipment) are ready.

Wearing protective clothing should follow a certain order, so as to ensure the correct and rapid wearing of protective clothing, play the role of protective clothing in work, and lay the foundation for taking off protective clothing safely after use. Generally, the order of trouser legs-boots-coat-mask-hat-zipper-gloves should be followed. Finally, in order to improve the air tightness of the whole system, adhesive tapes can be attached to the openings (such as the front of the door, cuffs, trouser leg openings, masks and hooded joints of protective clothing). In order to enhance the protection of hands, you can choose to wear two layers of gloves and so on. In the whole process, try to avoid the contact between the inner layer of protective clothing and the external environment, and avoid the pollution of protective clothing from the beginning.

It should be noted that chemical protective clothing must be replaced within the specified protection time when it is continuously polluted by chemical substances. If the chemical protective clothing is damaged, it should be replaced immediately. For airtight protective clothing or non-airtight protective clothing with good sealing performance, it is recommended to follow the principle of two people walking together, that is, at least two people enter the work area together in an emergency. The fabric of chemical protective clothing can provide several hours of effective protection, but when wearing air respirator, the working hours are determined by the working hours in air respirator. Pay attention to the effective service time of air respirator, and replace the cylinder in advance before it runs out. When calculating the effective working time, the time taken by walking and replacing equipment should be considered.

The principle of taking off protective clothing is to take off protective clothing safely without causing pollution to human body and environment. What needs to be emphasized here, but often overlooked, is that cleaning and disinfection should be carried out before taking off chemical protective clothing. The washing and decontamination mentioned here is only for taking off the protective clothing safely without polluting the wearer or the environment, not for the reuse of some protective clothing. According to different pollutants, decontamination can be very simple, for example, using a bucket of water to remove ordinary pollutants, or adding some detergent for washing. At this time, we should pay attention to some chemicals, such as concentrated sulfuric acid, which will react violently with water. At this time, we should first absorb the chemicals on the surface of clothes and then rinse them with water. This can avoid high temperature damage to protective clothing, and then cause pollution and injury to the wearer. After washing and decontamination, it is necessary to follow certain procedures to take off the chemical protective clothing, generally zipper-hat-coat-sleeve-glove-trouser leg-boots-respirator. Try to touch the outer surface of protective clothing before taking off gloves and try to touch the inner surface of protective clothing after taking off gloves. After taking off the protective clothing, wrap the outer surface and pollutants from the inside to the outside to prevent pollutants from contacting the human body and the environment. Take off the protective equipment to centralized treatment, to avoid expanding pollution in the process of treatment. It should be noted here that for complicated and bulky protective clothing such as air-tight or liquid-tight protective clothing, it is recommended to have another assistant to help the wearer to put on and take off, which can help the wearer complete some difficult tasks, such as adjusting and zipping, and finally check the condition of the whole protective clothing after wearing it. When taking off the protective clothing, the assistant should also take appropriate protection to avoid pollution due to possible contact with pollutants.

2. The wearing and taking off process of protective clothing and matters needing attention

The process of putting on and taking off protective clothing is as follows:

Wear: 1. Deploy the chemical protective clothing (the hood faces itself and the opening is upward);

2. Open the neck of the chemical protective suit, put the chest and legs into the pants, put on the coat and fasten the belt.

3. After wearing the gas mask, test the tightness of the gas mask at the first time, and fasten the chest and neck buckles of the protective clothing after confirmation;

4. Wear protective gloves, put down your coat and fasten it.

Take off: 1, untie each tie from bottom to top;

2. Take off the hood and open the chest to the shoulders. When taking off gloves, both hands retract the cuffs and grab the inner sleeves, and take off gloves and coats with both hands behind your back;

3. Turn out the waistband of your hands and take off your pants;

4. Take off air respirator and take off the gas mask.

Precautions:

1. For airtight protective clothing or unsealed protective clothing with good seal, it is recommended to follow the principle of two people walking together, that is, at least two people enter the work area together in an emergency.

2. The fabric of chemical protective clothing can provide several hours of effective protection, but when wearing air respirator, the working hours are determined by the working hours in air respirator. Pay attention to the effective service time of air respirator, and replace the cylinder in advance before it runs out. When calculating the effective working time, the time taken by walking and replacing equipment should be considered.

3. Try to avoid touching the outer surface of protective clothing before taking off protective gloves, and try to touch the inner surface of protective clothing after taking off gloves. After taking off the protective clothing, the inside faces outward, and the outside surface and pollutants are wrapped inside, so as to prevent pollutants from contacting the human body and the environment. Take off the protective equipment to centralized treatment, to avoid expanding pollution in the process of treatment.

Preparation before wearing protective clothing

Before wearing protective clothing, you must do enough inspection work, and you can't rely entirely on personal experience, otherwise it may cause serious safety accidents.

1, the protection grade and performance of protective clothing are consistent with the performance required in the use situation.

2. Confirm the size of protective clothing. Before wearing, please make sure that the size of protective clothing is suitable for your own size. Too large or too small will cause inconvenient movement or accidental damage and tear during work.

3, check the overall integrity of protective clothing. For example, there is no pollution on the surface of protective clothing and no cracks at the joints. Remove sharp objects, remove unnecessary keys and pendants with sharp objects from your body, so as not to damage protective clothing at work.

4. If it is A-class fully-enclosed chemical protective clothing, it is necessary to use a professional air tightness detector for regular air tightness testing, so as to use it in time in case of emergency.

3. Is there any good way to put on protective clothing?

Before wearing protective clothing, be sure to wear a gas mask on your head, so as to prevent poisoning before wearing clothes. Because of wearing a gas mask, the vision becomes narrow and unclear, so the action will become dull, and it is very difficult to wear chemical protective clothing. Although it is not easy to put on, many firefighters can put on protective clothing quickly. This requires us to think carefully

First, the chemical protective clothing must be folded and put into the bag. Every time you open it, you must take out the folded clothes from your bag before you can put them on quickly. Firstly, the folding method of chemical protective clothing is introduced. It should be rolled from the bottom, that is, from the shoes. Note that every tie in the middle is neatly arranged and not entangled.

Once again, you must wear a gas mask. After putting the gas mask on your head, you must open the lid of the gas tank, then take a breath and spit out the polluted gas.

When wearing the chemical protective suit for the third time, first pick up the chemical protective suit, grab the hat, shake off the clothes, spread out the clothes, put your feet into the pants of the chemical protective suit, put your hands into the sleeves of the chemical protective suit, jump a few times, and put your hands out when jumping, and the clothes will be put on.

Then we grab one side of the chemical protective suit and fold it to the other side, and the other hand cannot be idle. We have to touch the clothes from bottom to top, and then the clothes and velcro stick together.

Finally, put on the chemical protective clothing hat, tighten the rope on the hat, fasten the belts on the waist and feet, and carry the gas mask bag and chemical protective clothing bag on your back. We can say loudly: I'm dressed.

The overtime is arranged as follows

Put on a gas mask

2. Spread the chemical protective clothing on yourself, with the opening of the hood facing upward.

Unbutton your nose and waist, put your feet into the pants of chemical protective clothing, put on your coat and tie your belt.

4 put on the chemical protective clothing hat and fasten the neck strap. Put on gloves and make sure all the ties are fastened.

Take it off and arrange it as follows

1 Untie all the straps from bottom to top.

Take off the hood, open the middle part of the chest and pull down from the shoulder. When you reach the glove section, don't forget to pull the lining, and then the coat will be taken off.

Turn out the clothes at the waist and pull down your pants.

4. What should I wear to wear thermal protective clothing?

There is no requirement to wear other protective articles when wearing thermal protective clothing in the existing specifications, but thermal protective clothing is usually used in high temperature environment, so it is suggested to wear a cooling vest under thermal protective clothing to reduce the external temperature of human body to a certain extent and make it more comfortable.

Thermal insulation protective clothing refers to the protective clothing worn in high temperature environment, which can promote the human body to emit heat and avoid the harm of heatstroke, burns and scalds. Therefore, it must have the properties of flame retardancy, liquid repellency, no droplet generation when burning, and the integrity and wearing comfort of the clothing when it is hot.

Thermal protective clothing/category-146, also known as high-temperature protective clothing, is an important personal protective equipment, which refers to protective clothing that can prevent itself from being ignited, burned and smoldered after contact with flames and hot objects, and protect the human body from various injuries. It can be divided into protective clothing for high-temperature furnace operation in petroleum, chemical industry, metallurgy, glass and other industries and fireproof clothing for fire fighting and forest fire prevention.

In addition to thermal protection, thermal protective clothing must also have good practical performance and wearing comfort, such as certain tensile strength, tear strength and wear resistance. Dyeing is firm and washable, and it should also have certain heat and moisture transfer ability, which is beneficial to human heat loss and sweat evaporation, and has low physiological load.

In addition, protective clothing should be light in weight, easy to wear and loose in structure. There are no restrictions on running, climbing and jumping, and it is not easy to cause hooks. Strengthening measures should be taken in the vulnerable parts to meet the requirements of coordination and comfort and improve work efficiency.

5. Collection of background knowledge such as protection types of chemical protective clothing.

Offshore solid services:

Three-proof clothing, also known as chemical protective clothing, refers to clothing that can prevent nuclear, biological and chemical weapons (nuclear, biological and chemical weapons). These clothes are generally fully enclosed and have breathing filters. To understand the principle, we must first understand the mechanism of nuclear weapons, chemical weapons and biological weapons, so let's start with some background knowledge:

1. nuclear weapons: the killing effect of nuclear weapons is divided into two parts: instant killing and subsequent killing. Instant killing refers to the huge photothermal radiation, electromagnetic radiation and shock wave formed when a nuclear bomb is detonated.

Photothermal radiation has a certain range and angle. If we avoid this range and angle, the chemical protective clothing will be fine. If you can't avoid it, it will explode, and if you wear eight floors, you will die.

Electromagnetic radiation mainly affects equipment, as long as it is not carrying explosive electronic devices (such as electronic time bombs) to explode.

The shock wave also has a range, and it will be thrown up within the range. As for whether you fall to death or are killed or injured, it depends on the environment and has nothing to do with chemical protective clothing. It's out of range, so it doesn't matter!

As for the subsequent lethality, it means that the mushroom cloud formed after the nuclear explosion is actually a huge nuclear pollution dust cloud with strong nuclear radiation, which will drift with the wind direction, settle and pollute a large area, causing nuclear pollution to local land and water sources. If organisms are exposed to these radioactive dust through contact, inhalation and consumption, they will suffer from radiation sickness until they die. However, the monomer energy of radioactive dust itself is not large, and it needs to contact people directly and reach a certain amount to be fatal. At this time, wearing chemical protective clothing to enter and leave the nuclear contaminated area can effectively avoid inhalation and contact with nuclear pollution, as long as it is washed with water when it comes out.

2. Chemical weapons: Chemical weapons mainly cause death through inhalation of gas or liquid and skin contact. Whether it is functional or neurological, as long as people don't touch it, they will be fine, just like using masks and goggles dipped in water can effectively deal with tear gas. Therefore, the closed system and respiratory protection device of chemical protective clothing can effectively deal with chemical weapons.

3. Biological weapons can be divided into two types, one is host type and the other is medium type. Medium-sized biological weapons can kill by throwing pathogens into the air and water. When dealing with air-borne biological weapons, only special chemical protective clothing with breathing lungs can work, but general chemical protective clothing is ineffective; Generally, water medium does not spread through air, but does not contact; Chemical protective clothing is useless to host biological weapons, such as plague. Killing the host or looking for antibodies through variants in the host is the main measure.

In a word, chemical protective clothing has a good protective effect on the subsequent killing of chemical weapons and nuclear weapons, and has a certain effect on the air medium in biological weapons, while others are not so effective.
