The difference between children's life jacket and adult life jacket

1. The maximum adult life jacket can ensure the use of 140 kilograms of weight. Children's life jacket requires children to use within 45 kg of weight.

2. Adult Lifeline's buoyancy (n) 103, and children's life -saving clothing (n) 83.3.Generally, it is 7.5 kg/24 hours, and children are 5 kg/24 hours, so as to ensure that the surface above the chest can surface.The buoyancy of adult life jackets can float 7.5 kg of iron blocks in fresh water for 24 hours, and its buoyancy must not be reduced by 5 %.The buoyancy of children's life jackets can float 5.0 kg of iron blocks in fresh water for 24 hours.

3. The inside and outside of the child's life jacket should have a significant durable "children" image logo.

What kind of children's life jacket is good

1. The operation is easy to learn

The operation should be simple, the switching airbag is placed in a Smooth place, and the switching airbags must be able to inflatable quickly.Children are not familiar with life -saving equipment, so the operation of life jackets must be simple.There are no long bands on children's life -saving equipment. It is easy to wrap around the swimming equipment of other objects or other people in the water, and it is easy to danger.

2. Make sure that the life jacket is suitable for children's body shape and weight

The volume must not be too large. Children's watering can be used to protect the life jacket. Survival jackets will hinder children's normal activities in the water.Grasp the top of the arm opening and pull up gently.Let the child straight on his head.And see if the life jacket has passed the child's chin or face and whether there is excess space above the Sleeve.If so, life jackets are too big for children.

3. More safety deduction

To ensure the safety of children, the safety buckle of life jackets cannot be lower than two.And can be adjusted according to the baby's body shape.The seat Belt cannot be loosened in the water.The buttons of the seat Belt must be strong and cannot be easily opened.

4. The color should be bright

For example, orange, red and other dazzling colors can make lifeguards see at a glance, and some are also equipped with reflective boards.

5. Comfortable fabric

There are generally two types of life -saving fabrics, one: special nylon material, which is relatively low in price and wide use, but not durable; the other is: neoprene choppen rubber (diving material)., Feel soft and comfortable, friction, as long as high -end life jackets can use this fabric.In order not to rub the child's Skin, the waterproof cloth surface of the Skin can be selected close to the Skin, which will not wear the child's Skin during use.

6. Complete accessories

For example, survival whistle, etc., usually requires life jackets to have reflectives when playing with lower visibility.The life pocket and insurance Belt (passing through the Belt connected to the front film from the back of the life jacket) must be matched.

Children's life jacket purchase misunderstanding

1. Some parents think that various swimming circles can be regarded as life -saving supplies.The Swimming ring is an inflatable water toy. Its material and life supplies are completely different. The inflatable swimming rings can be easily overturned by the waves or leaked by foreign bodies. The child has a high chance of drowning.

2. Select fancy and cute life -saving equipment without paying attention to the material and function of the product. You may buy inferior products.

3. The inflatable airbags sold by some merchants are also counted as life -saving products. The gas Bags are the same as Swimming ring materials. It is relatively easy to scrape. It cannot play a role in life -saving in the sea. It can only be regarded as swimming equipment.

What is the principle of aircraft life jacket

life jackets are generally divided into two types: inflatable life jackets and foam -type life jackets.

1. Foam -type life jacket refers to the fabric made of nylon or dendrome rubber. It is filled with buoyancy materials such as foam boards in the middle. It has enough buoyancy to wear on the body so that the head of the water drop can expose the water.Generally, what we use belongs to the sea life jacket.It uses EVA foaming material inside, which has been compressed by 3D three -dimensional forming. Its thickness is about 4 cm (domestic products are 5-6 thin hair materials, which is about 5-7 cm thick).The life jackets produced according to the standard specifications have its buoyancy standards: Generally, it is 7.5 kg/24 hours, and children are 5 kg/24 hours, so as to ensure that the surface of the chest is paid above the chest.

2. The inflatable life jacket is divided into two types: automatic inflatable life jacket and manual inflatable life jacket. This kind of life jacket is made of high -intensity Waterproof material. The inflatable life jacket is mainly sealing inflatable vest airbags, micro -pressure gas cylinders and fast -moving air cylinders and fast.The composition of the inflatable valve is often used in the possibility of falling into the water.

Under normal circumstances (not inflatable), the entire inflatable life jacket is Hanging on the back of the shoulder like a strap. Because the volume is small, it does not hinder people's homework.At all times, or automatically expand and inflatable (automatic inflatable life jacket) according to the action of water, or by pulling a cable (manual inflatable life jacket) on the man-charged air valve, it can be inflated into 8-15 kg of buoyancy within 5 seconds.Safe clothes; life jackets hold up the human body upward, so that the head and shoulders are exposed to the surface, so as to obtain safety protection in time.

This kind of life jacket is made of water -resistant and breathable materials on the surface. In addition to paying attention to its buoyancy when choosing, it should also be noted that sharp objects can be avoided or worn through the waterproof layer.Inflatable life jackets should check if they are leaking before use.

What are the use of aviation life jackets

Many friends may think that the plane is safe. If there is an accident, there is no parachute effect. In fact, once an accident occurs, it is completely unrealistic for passengers to escape from parachute.

1. Civil aircraft is not the same as fighters. The engine is next to the cabin door. After parachuting, it is easy to get rolled into the engine, so it is more dangerous to say.

2. The skydiving looks very simple, but in fact, even professional paratroopers have to be trained for 3 months before parachuting. Passengers who have not trained have a greater risk of parachute.

3. Therefore, compared with parachutes, life jackets are more practical. In addition, even if the plane encounters an accident, it can be controlled. The pilot can still control the emergency landing of the plane. The forced landing may land in the lake., River and the sea, at this time, life jackets can play a role.

4. Aviation life jackets also have a certain warmth function. After the cold, the weather can also provide passengers with a temporary cold protection effect.

5. The color of the life jacket is bright, and the rescue personnel can be reminded from a long distance during rescue.

1. What is swimming life -saving equipment

swimming life -saving equipment, scientific name, swimming float, also known as floating ball, is a life -saving float, a striking orange airbag, a long strap, one tied to the swimmer's waist, and one orange airbag.Looking from a distance, like a chubby little bug followed the swimmer.

This kind of life -saving float is a life -saving equipment designated by the International swimming Federation and the China swimming Association. The design of the double airbags will not affect the swimmer swimming, and it is safer than the lifeburn.In terms of use, it is also more convenient. The length of the band is well controlled and is not easily entangled.And the swimming float color is eye -catching, and it can be used as a life -saving symbol in water.Carrying swimming life equipment in open waters can prevent many swimming accidents from happening.

2. What are the advantages of swimming floating?

1. It can play a warning.The color is bright and can prevent accidents with the traversal.

2. When swimming needs to supplement food or water, you can grasp the swimming float and press it into the water with the help of buoyancy to rest. After the discomfort is eliminated, the physical strength recovers, you can continue to swim.

3. It can play a role in self -rescue.In the event of an accident when swimming, or cramps in the legs, you can save yourself and rest, waiting for others to help further.

4. Can play a role in rescue.Once you really meet a swimmer, you need to help, unlock your swimming float in time, and use it for swimming friends to save each other.

5. You can support it when you are inadequate.Tour swimming floating in the river, lake, and reservoir, tired, you can climb in swimming floating and rest, and then take a rest and rest, so that the swimmers can quickly improve the travel journey.

Third, the shortcomings of swimming floats

1. It may leak air.

2. It is not easy to catch it too much. When the flood is large, it is easy to entangle floating bamboo, branches, anchor cables (ropes), etc., and it is not easy to liberate.

3. When saving people, they cannot dive in time. After swimming in deep water, after the drowning person sinks, the general rescuers generally give up because they cannot dive to the end.

4. What are the types of swimming floating?

1. Rugby -style swimming float

This is the most common float. This kind of swimming float is suitable for swimming pools, rivers, and lakes.Generally speaking, it is suitable for waters with small storms.

2. Flying sauce swimming float

swimming floating inner storage warehouses are suitable for swimming enthusiasts in the shore with small waters with small storms and Outdoor swimming.

3. Pillow -shaped swimming float

This swimming float is large, because there are ropes on the side, which are easy to grab in the water, and are often used in open waters of large storms.

4. Cillar swimming float

Because of its large buoyancy, it can be used in clothing and other characteristics. It is often used for long -distance drift swimming and winter swimming.

Swimmer said

The warning and psychological suggestion of swimming floats are greater than the actual effect.I bought one, tens of yuan, can put some small things, which is very convenient.The trumpet can provide enough buoyancy of adults, but this person who can swim and has a floating foundation.

Do not swim, do not float, or have no sense of balance, and the effect will be poor.

Check the closed conditions before. After launching, be careful not to damage the sharp objects. Pay attention not to entangle your body and cause panic.

swimming is not absolutely safe. It is best to keep the three -point strength in the wild.

What is the material of the life jacket

Life -saving fabric

1. Special nylon material

This kind of fabric is relatively low in price, wide use, but not durable

2. Neoprene choprene rubber (diving material)

This kind of fabric is more expensive, feel soft and comfortable, friction, as long as high -end life jackets can use this fabric.

Life -saving clothing

1. Polyethylene foam plastic

The price of this linoleum is relatively low, with sufficient buoyancy and wide use surface, but the buoyant of the buoyance will change with the time of soaking in the water at about 5%.

2. EPE pearl cotton

The price of this linoleum is obviously more expensive than the foam plastic, and its advantages are obvious.The buoyancy is strong, the life jacket is easy to fold, and it is easy to dry. More importantly, the buoyancy is soaked in the water for a long time.

Life clothing material requirements

1. Plastic should be a soft -closed foam plastic. During the validity period, it is not affected by the erosion of seawater, oil or mold and affects its normal use.It can be stored within the temperature range of -30C to 65C (243 ~ 338K) without damage. It can maintain its performance within the water temperature range of -1c to 30C (272 ~ 303K).

2. Rich kapok oil and must not contain other impurities. The physical properties and moisture content should meet the requirements of norms.After being surrounded by hydrocarbon flames for 2 seconds, the source of the fire should not be burned.Between the kapok and the raw clothing cloth of the kapok life jacket, there must be a waterproof inner cover made of rubber or other waterproof materials.

What is the role of life jacket

1. Help people float on the water

Putting on a life jacket allows people who can't swim to keep their heads exposed to water, thereby reducing the probability of drowning.For those who can swim, the buoyancy of life jackets can save them more physical strength.

2. Cold protection and warmth

Most of the life jackets are made of foam plastic. In the cold water, it can effectively keep warm and reduce the loss of human heat.

3. increase the rescue rate

life jackets are generally bright in color and have anti -light strips, which are convenient to be discovered.At the same time, many life jackets and survival whistle can help people send a distress signal without physical saving.

4. increase the survival rate

Safe clothes can help people float on the surface, which greatly reduces the probability of drowning.At the same time, many life jackets are also equipped with first -aid Bags, which can help people survive better in the harsh living environment.

What are the swimming pool life equipment

1. Life chair

Also known as Observation Call and Watching chair, it is one of the necessary safety facilities for swimming places.The lifeguard sat on a life -saving chair to overlook the entire pool or entertainment venue to ensure the safety of any swimmer.The life chair is made of stainless steel to ensure that it is used for a long time in the warm and humid environment of the swimming places. The chair surface is made of ABS imported materials. It is waterproof and sun -split radiation.

2. Life Circle

It uses high-density polyethylene as the body, with an internal high density polyurethane closed-hole foam and plastic.It is usually made of cork, foam plastics or other light materials with smaller proportion, with canvas and plastic on the outer bread.It has the characteristics of high temperature resistance, no shrinkage, rupture, expansion, and decomposition.The color is generally orange, and the color is very distinct. At the same time, the four beige plastic rings are evenly distributed on the Swimming ring, which not only increases the beauty, but also makes the quality better.It has four holes for penetrating the rope to facilitate the life of the shore.

3. Safe rod

Combined by the life hook and telescopic rod, it belongs to a swimming life supplies.It is mainly used as a must -have life -saving equipment for swimming pools and water parks, and is used to swim life -saving professional tools to quickly salvage drowning.The length of the life hook is 5 meters and 8 meters. It is mainly based on the size of the swimming pool to choose a life hook of different lengths to ensure that the drowning person can be salvaged faster and more effectively.

4. Safe clothes

It is a kind of rescue of life. It is designed with a vest that uses nylon fabrics or neoprene, buoyancy materials or inflatable materials, reflective materials, etc.It is one of the life -saving equipment on the Ship, which is generally vest, and made of foam plastic or cork.Putting on the body has enough buoyancy to make the water falling from the water.

5. Life Rope

It is a kind of swimming pool life -saving equipment.The end can be tied to the life circle, and the pool is used during the life of the pool.The life rope is mainly used for long -distance life -long life. It can quickly rescue those on the shore to increase the speed of life.When the swimming pool life rope is used, one end is tied to the life ring, the other end is fixed on a firm object, loosen the rope and throw the lifebing circle away from the rescue, and then pull it back to the life ring through the life rope.The rope can float on the water, which is generally used in large swimming pools, as well as natural waters (such as rivers reservoirs, sea rescue at sea).

6. Safe bag

Used for life -saving products, such as water cups, medicines, gauze, and so on.

How to use life -saving equipment

When many friends go to swimming in the swimming pool, they will find a strong man sitting on the shore's high chair sitting on the shore.It's a lifeguard.The lifeguard is sitting in a life -saving chair. When a drowning person is found, the drowning person is generally rescued by indirect life -saving and direct life -saving methods.

1. Indirect life -saving

Use some life -saving equipment in the swimming pool to rescue the drowning person. Usually, when the drowning person is stronger than the edge of the pool, the lifeguard pulls the drowning rod to the drowning rod by throwing out the lifebuilding ring or the life jacket.The situation is serious, and artificial breathing and cardiopulmonary resuscitation need to be performed. Urgent treatment is used for emergency treatment, and it is taken to the Hospital.

2. Direct life

When the drowning accident occurs far away from the edge of the pool, it can only take a direct way of rearing, that is, lifeguards enter the water to bring the drowning person ashore.Direct life is divided into five parts: water entry, approximation, liberation, drag band, and ashore. The water can be divided into three most common methods of water access, such as leapfrog, frog legs, and fish leap -type.

Nearly the most dangerous process when the drowning is rescued.According to the situation of the drowning person, different approach methods, including the three close methods of front, back, and side. The correct approach method can effectively reduce the danger of rescue during rescue.Then it is liberation. Generally, a reasonable approach method will not be used.But in case you are caught or hugged by the drowning person, you will use liberation technology.The life -saving test is generally analog liberation on the shore.The next step is to drag the technology. Primary lifeguards generally have a dragging technology. The most common is the dual axillary drag method.
