life jacket How to classify

1. Divided into use by use

(1) Marine Lifejacket, (Marine Child Lifejacket), suitable for life -free use of the ocean coast and inland river life. The raw clothing ravage is greater than 113N.5%.Lifeline buoyancy material: polyethylene foam plastic.

(2) Marine Work Lifejacket, which is suitable for work and use of various people along the coast and inland.The buoyancy of life -saving clothing is greater than 75N. After soaking for 24 hours in the water, the buoyancy loss of life clothing should be less than 5%.Lifeline buoyancy material: polyethylene foam plastic.

(3) Leisure life jacket: It is also called Water sports Lifejacket. The fabric is multi -chlorine rubber composite material, with a variety of color matching, fashionable and beautiful.It is mainly suitable for waters to play, learning swimming, rafting, fishing, etc. to wear life protection effects.Buoyant material: polyethylene foam plastic.

(4) Sea life jacket: The EVA foam material is used inside, which has been compressed by 3D stereo. 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.The surface is made of water -resistant and breathable materials. In addition to paying attention to its buoyancy when selecting, it is also necessary to pay attention to whether the Belt interface is damaged to prevent no gravity floating after water.

(5) Aviation life jacket: It is rarely used, but when an accident occurs, the safety of passengers can be used when falling into the water.

2. Divided into the principle of buoyancy,

(1) Filling -type life jackets, that is, use nylon or chlorine rubber as fabrics and fill the buoyancy material in the middle.

(2) Inflatable life jackets are made of high -intensity water -proof materials, similar to the principle of inflatable lifeburn or Swimming ring.Automatic inflatable or passive filling.However, this kind of life jacket should pay attention to: absolutely avoid sharp objects to piercing or grinding the waterproof layer. After leakage, it will cause serious consequences of unimaginable imagination.

What are the models of life jacket

1. HS-BS2 type

The HS-BS vest manual inflatable "Blay life jacket" is worn on the same vest before qi. When falling into the water or encountering danger in the water, pull the manual valve and quickly inflatable in 2 seconds.There are blowing mouths on the life jacket, and it can also be blown.The HS-BS vest manual inflatable "Blay life jacket" opens the manual valve when it is in danger. The cylinder high-voltage gas is filled with the life jacket.On the water surface.

2. HS-BZ2 type

The HS-BZ vest automatic inflatable "Blay life jacket" The front chest and back of the vest of qi and the vest quickly swell to form an airbag. It generates 10 kilograms of buoyancy in the water and automatically corrects the human body., Even in a coma state, you can breathe on the water on the water and wait for rescue.The airbags are also equipped with a 3M reflector, helping for help, and water battery lamps for help.

3. HS-02 type

HS-02 type qi bloating lifebuilding (inflatable life Belt): When unfortunately, the automatic gas-filled valve is installed with water-sensitive elements and springs on the basis of manual inflatable valve.The spring stretchs, the thimble piercing the cylinder storage gas cylinder high -pressure gases quickly swell the ring -shaped airbags, and the connection band becomes a lifebuilding circle. It is placed under the two armpits, and the buoyancy exceeds 9 kg to float the human body in the water surface to achieve life -saving.The HS-02 qi bloating Belt-type lifebuilding uses high-strength environmental protection TPU composite fabrics, adopts advanced mold thermal synthesis, and is equipped with micro-high-pressure gas storage cylinders and automatic filling valves.Suitable for maritime construction, water sports and coastal ships.

life jacket What are the styles including

1. Neck Hanging

Before the qi, wearing it like a vest. When falling into the water or encountering danger in the water, he opened the manual valve and quickly inflated in 5 seconds.There are blowing mouths on the life jacket, and it can also be blown.When you are in danger, pull the manual valve. The cylinder high -voltage gas is filled with a life jacket. The front chest and back of the vest quickly swell to form a airbag. In the water, 10 kg of buoyancy can be generated to float the human body on the water.

2. waist Hanging style

When leisure, use a webbing Belt to fix the waist. After accidentally falling into the water, a horseshoe -shaped life ring is formed after inflating the water.The clothing meets the latest requirements of the SOLAS Convention and the IMO. After CCS certification, it is allowed to apply applications in the fields of ships, ships, maritime anti -smuggling, water construction, water sports, salvage, pilot, flood prevention, and sea fishing and leisure.

3. Waste -type type

The airbag is packed in the small bag and connected to the waist with the Belt.It does not hinder the normal operation of water and the waist -type baggage -type baggage bag on the waters and ships on the boat.After inflatable airbags, the airbags will automatically pop up from the bag. Because there is a buckle connection, the airbag drives the human body to float on the water surface.Essence

The bright color in the life jacket or the color with fluorescent components will stimulate our optic nerve for people's eyes.It may be related to the wavelength of this color. It is easy to accept and be confused by other colors.This will be more conspicuous.In this way, if you have an accident, you can be easily discovered and can be rescued as soon as possible.

What types of family emergency packages

1. Earthquake emergency package

On the basis of ordinary family emergency packages, coupled with sufficient food, water, and medical emergency package, a Earthquake emergency box can be formed. Considering that the flashlight lighting, mobile phone, and radio charging in the Earthquake are a big problem.Prepare a hand -shaken charging flashlight with a charging function.

2. Medical emergency package

Everyone is familiar with the medical emergency package. It is similar to the small pills in our family. Basic first -aid supplies include bandaging, hemostasis, fixing, fixed, fixed, fixed, fixed, fixed, fixed, fixed, fixed, fixed, fixed, and foggy foggy fog, and alcoholic cotton pads, alcoholic cotton pads, alcoholic cotton pads, alcoholic cotton pads, alcohol cotton paddish, alcohol cotton pads, alcohol cotton pads, alcohol cotton slices, and white medicine fog agents in Yunnan.Basic medicines for wound treatment; personal medicines include daily anti -inflammatory drugs, anti -laxatives, and vitamin tablets, especially antidiarrheal medicines. After the disaster is trapped, due to bad survival conditions, it is easy to cause malaria.It is very dangerous.

3. Outdoor emergency package

The escape self -rescue of Outdoor emergencies is relatively professional. It can be equipped with a professional escape rope. It is 20 meters long and the maximum load of 2040 kg. It is more safe for the escape to escape.Hold quickly.The escape rope also has a night reflective function, and it is easy to be found by search and rescue personnel outside.You can also prepare a non -slip glove. It uses a flashlight or escape rope during escaping to prevent the hand from being injured. The bumpy side is the palm of the hand.

4. fire emergency box

fire emergency boxes can be based on a special fire escape mask on the basis of home emergency boxes. It has a protective effect on carbon monoxide, hydrogen cyanide, smoke, and poisonous mist, with a role of about 40 minutes.It should be reminded that if the mask's plastic bag is not used, do not open it, otherwise the substances with adsorbing effects such as activated carbon will fail and affect the protection effect.Alsofire blanket, it is made of glass fiber, the main role is to extinguish the fire and fire and fire.The fire escape package is also used to escape rope. It can tolerate the high temperature of more than 200 degrees Celsius, which is still fluorescent.

Where should the family emergency package be placed?

Many friends who bought emergency packages do not know where they should put the emergency package at home. I feel that the emergency package will only be used in the emergency state.Throw the emergency package away from the basement or a grocery room.

In fact, this approach is definitely wrong, because when we are really in critical moment, we have no time to go to the basement or grocery room to find an emergency package. So isn't the emergency package buy it in vain?Therefore, the emergency package must be placed in a conspicuous and easy place at home, such as the main bedside table or living room drawer. In short, do not put it in a lot of messy things, which will cause many unnecessary troubles.

What are the types of life rafts?

1. Rigid life raft

Rigid life rafts are also called traditional life rafts. The structure is to use galvanized iron, aluminum alloy plates, stainless steel plates or hard plastic materials for the four weeks of life rafts to make several linked air boxes as the main buoyant part of the life raft.Then cover or does not cover the flame retardant material; the top of the raft is equipped with a fixed rigid Tent and entrance, and the bottom of the raft is a wooden lattice board.Usually stored on the sliding shelves on the side of the Ship or driving the deck of the table. When the slide is opened, the slide is opened.

The biggest feature of such life rafts is the simple structure and low cost; but its size is large, heavy and less carrier.

2. Inflatable life raft

The inflatable life raft is divided into qi -deficient life rafts, qi -type life -saving floats, and bloating self -supporting righteous life rafts.

(1) Bloating life raft

Such life rafts provide buoyancy from upper and lower floating tots made of rubber materials. They are made of double -layer waterproof nylon cloth into tents, and they are swollen into round, elliptical or polygons with gas.After the life raft is stacked, it is stored in the glass reinforcement storage cylinder with the genus.The design of the qi -blee -type life raft is advanced, tight structure, good safety, convenient movement, simple operation, and rapid formation, so it is widely used in various civilian and military ships at sea.

There are two types of bloating life rafts, namely mechanical hanging type and throwing type.The mechanical Hanging raft has been inflated before entering the water; the throwing life raft is inflated and shaped on the sea surface, and the life raft may be overwritten during the inflatable formation process.Essence

(2) Blay -type life -saving floating glute

In addition to no tents, the qi -bleaching life -type rescuer, its manufacturing materials, main structure, performance requirements, forming process, storage requirements, genus equipment, etc., are the same as the qi -type life raft, but the application method only has throw -in type investment types.EssenceIt does not have a Tent. After the raft is inflated on the water surface, the personnel in the water can be set in the two asymptom platform or any side of the floating glute from the two sides of the floating glute, which is convenient and fast.The rated passengers are more than 50 people with the bloat -type life rafts with tents, and they can carry up to 50 people.

The double -layer raft of the life -saving floats is located between the upper and lower floating tires.Therefore, regardless of whether it is applied by the sea conditions, the floating glute is in a state of romance (available on both sides) after inflating the sea surface, and no manual correction is required.This kind of life -saving floating glute has a greater impact on sea conditions and climate because there is no Tent, and the main equipment is on the passenger wheel.

(3) Blay qi self -supporting righteous life raft

In order to overcome the overwriting situation of the qi -jellyfield life raft during the formation of the sea surface, to avoid the difficulty of launching the water to support the righteous raft, and to meet the needs of the maritime survival personnel on safety and rapid response.Once such life rafts are overwhelming during the casting process, because the top of the raft is round, it can reduce the contact surface with water.After the inflatable formation is completed, you can correct it yourself.

Bloating life raft performance requirements

1. In terms of life raft, it should be able to withstand exposure of floating for 30 days under all sea conditions.

2. The life raft and its genus can be used safely and normal after being put into the water from the 18M altitude.

3. The life raft floats on the water, and it can withstand that at least 4.5m above the bottom of the raft can repeat the height of the height, not damaged, and does not affect normal use.

4. All passengers and geniuses of life rafts and a sea anchor can be released. They can be dragged at a speed of 3 KN in static water and are not damaged.

5. The life raft should be equipped with a canopy that can be automatically supported when landing.

6. The quota of the life raft must not be less than 6.

7. The total quality of the life raft, the total quality of the items and containers must not exceed 185kg.In addition, it also requires specific requirements for the equipment of the life raft, the installation facilities of the life raft, the strength of the lifting life raft, the dealership, the container of the installation raft, and the free floating drop -off.

storage of qi -jelly -type life rafts

1. The life raft and its storage device should not affect the use of life -saving equipment stored in any other location.

2. In the case of safety and feasibility, as close as possible.In addition to throwing out the life rafts that landed out of the outshore, the life raft should be in this position: that is, the life raft in the landing position, when the full -load Ship is not good for 10 and reaches 20 to any sideWhen the angle of immersion in the edge of the open -air deck of the Ship (from the larger angle of the two), it should be not less than 2 m from the waterline.

3. When the suspended life raft can be used in the state, the two boats should be allowed to complete the login and landing preparations within 5 minutes.

4. It is stored in a safe and shielded place and is protected to avoid damage caused by fire and explosion.Especially the life raft on the oil tanker.It should not be stored above the cargo oil compartment, polluting oil cabin or other explosive or dangerous cargo compartment.

Inspection and maintenance of life rafts

1. Observation inspections of life rafts and their storage and settlement equipment per week to ensure that they are available immediately and make records.

2. Each month, check the rapid decircation, fixing hooks, fixed cables, rope plugs, connecting buckles, and life raft containers on the life raft.It should be repaired immediately so that it is in a good technical state, and it must be recorded.

3. The time interval of the life raft maintenance does not exceed 12 months, and it can be exhibited to 17 months with the consent of the competent authority.

4. The life raft must be maintained at the maintenance station recognized by the competent authority, or the certification personnel approved by the competent authority are inspected on the Ship as required.The main items for maintenance are: the surface quality of the raft (firm paste, damaged, etc.) inspection, inspection of the raft container, inspection of the dissemination of the raft, the presence of the life raft with it, the inspectionCheck, start the punching needle, start the inspection of the rope, and perform an inflatable test and inspection.In short, these inspections should not neglect any small parts, any parts, any part of the loading parts, and any one.Discover all bad situations such as shortage, damage, mildew, etc., must be supplemented, repaired or replaced to maintain its good technical state.

5. Under the general storage and use, the life of the rafts of the life raft is 10-15 years, which exceeds the service life and must be replaced.

6. If the static water pressure releaseer can be replaced on the Ship, there must be a qualified spare parts on the Ship. After the use expires, it should be replaced in time.

7. Static water pressure release device (except for being replaced by itself), the time interval of the maintenance is 12 months; it can be exhibited for 17 months after recognition by the competent authority.

8. The surface of the container of life raft must not be painted. The signs and technical data indicated on the container must be clear and obvious.You cannot be stamped particularly on the container, and you cannot add a fixed incorrectly.

Bloating life raft application method

1. Plug -in life raft

When the Ship is in danger, the raft can be thrown into the sea by manpower or with the help of its own gravity, and rely on the strong rope to pull the inflatable bottle valve to make it inflatable and forming in a very short period of time.

2. Mechanical Hanging

It is mainly used for passenger ships or scientific examination ships and teaching boats.First remove the raft from the storage room room or deck store and hang it on the life raft Hanging rack to pull the inflatable and pull the rope to make it shake on the side of the side.Then it is a climbing platform made by the tape to make the crew and the passenger from boarding the raft from the deck, and then hang the raft to the water.In this way, the occupants avoid difficulty climbing ladder and diving.

How to wear LP knee pads

precautions for LP knee pads wearable

1. The LP knee pads cannot be used for a long time. In daily life, if you need to wear a knee protective, you can wear it for 1-2 hours to remove the rest for half an hour; you must not wear it for a long time., Especially when using tight knee pads.

2. It is best to wear tights first, and then put on the LP knee pads, which is convenient. While it does not affect the Skin, it can maximize the use of knee pad function.

3. For tillar tendonitis, softening of cymbal Bone, citrus pain syndrome, and iliac tibial syndrome, the Bone band is recommended.Tied to the below the tiny tendon below the knee to help disperse the tendon of the tendon; it is tied to the above knee to relieve the tension of the iliac tibial tibia.

4. It is recommended to remove the LP knee pads immediately after Running to avoid the muscle degeneration of tissue surrounding the knee joint.

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.
