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.

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

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.

The correct way to wear the bloated life jacket

1. Put your head into the life jacket.

2. Tie the straps on the left and right sides.

3. Pull the tension on the left and right sides, the inflatable valve is opened, and the life jacket is inflated within a few seconds.

The inflation function of the qi -blee -type life jacket

1. Manual inflatable: Pull the pull rope on the inflatable device before or after falling or after falling or after falling or after the water, so that the tie rod is not less than 90 degrees, the thorns are pierced to pierce the gas cylinder film, the high -pressure CO2 gas is poured into the airbag, and the buoyant is generated after the gas swells.

2. Automatic inflation: After the water is dropped into the water, the life jacket is immersed in the water to soften the water sensitive element in the automatic device, loses blocking the needle, and the spring stretch pushes the piercing needle to pierce the gas cylinder sealing film CO2 gas to fill the airbag and generate buoyancy.

3. Blowing the mouth is a one -way valve type, and the one -way valve is automatically closed after blowing.

What are the types of qi -style life jackets?

Blay -type life jackets are divided into three types according to the appearance style:

1. Vest -style qi qi and life jackets are commonly known as horses -type qi qi life jackets.

2. scarf -style qi and life jackets are tied to the neck like a scarf.

3. Belt Bloating life jacket, also known as qi -type Belt life ring, water seat Belt.

There are two specifications of all styles of qi and life jackets, one manual type and one automatic type.Suitable for fire, maritime police, water police, armed police, border defense, maritime affairs, fishery administration and other units to engage in water rescue activities.

The performance indicators of qi -blee -type life jackets

1. Automatically inflatable within 5 seconds of water, generate more than 15 kg of buoyancy.The 24 -hour buoyancy loss is less than 5%, and the performance of the main accessories and materials meets national standards.

2. The airbags are made of imported polyether TPU materials, which have excellent aging resistance and hydrolysis characteristics.

3. The dry side of the water is greater than 120mm, and the backward angle is 20-50 degrees.

4. The product is standard for search whistle and reflective stickers.

What are the fabrics of qi -qi -type life -saving clothing

Bid-type life jackets use TPU fabrics, TPUs (Thermoplastic Polyurethanes), and thermal plastic polymethlate, which is a linear embedded cluster composed of low polymer polymirol soft segments and diisocyanate-expansion hard segments.The TPU can be made of saliva, film blowing, pressure delay, or coating, which has the excellent characteristics of good elasticity, strong toughness, abrasion resistance, good cold resistance, and environmental protection and non -toxic.TPU fabric has the following characteristics:

1. Hardness planning wide

After changing the ratio of the components of the TPU composite fabric, the Tent cloth can get products of different hardness, and follow the hardness of the hardness. Its product still adheres to excellent elasticity and abrasion resistance.

2. High mechanical strength

The carrying capacity, impact resistance and shock absorption function of TPU composite fabric products are excellent.

3. Extremely cold -resistant

The glass state changing temperature of the TPU composite fabric is relatively low, and the canvas factory still adheres to excellent elasticity, softness and other physical functions at minus 35 degrees.

4. Good processing function

TPU composite fabrics can be processed with common thermoplastic materials, such as injection molding, extrusion, pressure extension, and so on.At the same time, the TPU composite fabric/cloth processing with certain polymer materials can obtain a polymer alloy with complementary functions.

5, oil resistance, water resistance, mold resistance.

6. Good recycled utilization.

There are two methods of TPU composite fabric. One is called and then sticked: first make it into a TPU film, then fit the glue with the fabric, and the other is called online composite: apply the glue on the fabric may not be glued.The fabric is made into a TPU composite fabric or clipped mesh.

What are the life -saving equipment on board

1. Safe suit

The quantity is equipped according to the number of passengers to ensure that each person is guaranteed.At the same time, it is equipped with sufficient number of life jackets at the duty offices. In addition, it is easy to see the deck.And more than 10%of the children's life jacket with an additional number of passengers.Ship life -saving clothing must be orange and need to be configured. The name of the Ship must be sprayed on the life jacket. It has strict requirements on the area of buoyancy and reflective materials. Because of the relationship of the waves, it also requires the neck support.

2. Insulation life -saving clothes

Also known as the water -soaking insulation suit, it is a life service that deal with the cold weather in winter. It is configured in the lifeboat according to the number of 3 sets of each boat.This kind of heat preservation effect is like this. On the calm water surface of 0-2 degrees, 6 hours can ensure that the body temperature is reduced by no more than 2 degrees. It floats on the sea and does not exceed 200 grams in 1 hour.In the low-temperature seawater of 0-2 degrees, a normal human beings usually coma in 12 minutes. In low temperature, if you only wear a life jacket to escape, there is only 15 minutes of rescue time, which is tantamount to listening to the heaven.Equipment is necessary.

3. Life Circle

According to the structure of the Ship and the captain, the corresponding amount of lifebuilding is equipped on both sides of the Ship and the first and tail.At the same time, half of them are equipped with bright floating Lights, and at least two lifebrow circles are equipped with a smoke signal.The Lifeline on the Ship is different from the life of the general swimming pool. Usually the material is formed by polyethylene, and the internal filling of foam plastic. According to the requirements of the regulations, it must be orange.

4. Lifeboat

Refers to a boat used to rescue the dangerous personnel.For example, a crew is settled and needed a small boat to rescue. At this time, rescue boats are generally used. One is that the rescue boat is good at maneuverability, and the second is that the rescue boat releases relatively quickly.The rescue boats used on the Ship are usually rigid, and the power is the out -of -out -of -out engine.The passenger Ship of the international route is equipped with 75%of the total number of members.At the passenger Ship of domestic routes, the entire Ship's lifeboat is equipped with 40%of the total number of members.

5. Safe raft

Determine the number of life rafts according to the number of passengers. Usually, the number of people with any life raft configured at any side is 1.5 times that of the number of crew members.Divided into rigid and qi -type life rafts. The rigid life raft has fewer applications. Most of the qi -type life rafts used on the merchant Ship. In short, it is a non -dynamic inflatable raft.When there is no inflatable, put it in a container. When needed, the compressed gas cylinder in the container quickly inflate the life raft.

6. Safe Floating Host

The passenger ships on class B are equipped with a total of 3%of the life -saving floats.

7. Life signal

In the driver's desk, a proper number of life -saving signals are equipped in the life -sale raft.Such as the flame signal, the red light rocket parachute signal, the smoke signal, etc.

8. Throwing rope equipment

4 sets of throwing equipment are placed on the driver's table.The emergency evacuation system is placed on both sides of the Ship, which facilitates passengers to evacuate the Ship in time.

9. Dangerous communication tools

Middle and high -frequency digital selective call system.Hand -pinch or high -frequency wireless phone, indicate the position of radio emergency instructions in the position, facilitate radar recognition, and the radar responsers found. These radio devices are switched to the driver's desk or the house.

What are the water life -saving equipment?

1. Floating installation

Floating equipment mainly includes lifeboats, life -saving vests, and waterproof and cold -proof flight uniforms.Lifeboat is a kind of qi-type rubber boat that can be loaded about 4-7 people.After the gas boat of the rubber boat is inflated, it generates buoyancy on the water to sink.When not in use, the lifeboat is folded and packaged in the canvas bag. When used urgently, open the canvas bag, and the lifeboat can be automatically inflated. The life -saving vest and waterproof and cold clothes are when the on board is leaving the plane.The floating clothing worn on the body.Cold anti -flying service, in the zero -degree water temperature, can ensure that the personnel on the machine do not freeze.Once the waterproof flight suit is contacted, a layer of waterproof clothing is formed immediately on the surface, ensuring that the personnel on the aircraft are not soaked by seawater after the water falls into the water.

2. communication equipment

communication equipment is a small sending and receiving reporter.After this small -scale sending and receiving reporter is soaked by seawater, the performance of the machine does not change, and the call distance is 100 kilometers.

3. Signal equipment

There are many types of signal equipment, which can be divided into visual signal equipment, audio signal equipment and signal flags.The visual signal equipment has a reflector, sea water staining agent, smoke, etc., and the fire light, flash, incandescent light, flash bombs, tracer, signal bullets, etc. at night.The audio signal equipment includes pistols, whists, alarms, and shouts for shooting.The signal flag is divided into three sides of red, green, and white.Persons on board use these equipment to express various signals and requests to rescue.

Although the water life -saving equipment is relatively complete, its life -saving ability is limited. After being killed, the personnel on board should contact the poor personnel as soon as possible and take measures to strive for a long time to survive to wait for rescue.

What are the types of water life supplies?

Water life -saving equipment mainly includes: life jackets, life rafts, life -saving radio stations, and maritime body weapons and shark -proof agents.

1. slide a life raft

According to statistics, about 10%of the accident occurred in the accident occurred by passengers.The aircraft forced the aircraft to solve the problem of rescue of passengers.Floating equipment has a personal life jacket and a Lifeline for multiple people.In addition, emergency inflatable slides can also be used as floating life equipment for water survivors. Its carrier capacity is much greater than the lifeboat. Generally, it can be loaded 50 to 100 people. It is a good water life -saving equipment.

The slide -life raft is installed under the aircraft's emergency cabin. When the door is emergency opening, it will automatically expand and inflatable to the aircraft.Because the slide life raft is directly connected to the cabin door, passengers can easily board the life raft.When all passengers board the life raft, pull out the "forced landing handle" connected to the exit floor of the door exit, which can separate the life raft and the aircraft.

The slider is equipped with emergency items and communication equipment, such as rafts, floating anchors, repairing equipment, signal generators, emergency positioning transmitters, etc.Emergency positioning transmitter is in seawater, and the seawater battery begins to work.

2. Safe Ship

On passenger planes without slide -life rafts, the floating equipment on the water is mainly inflatable lifeburn.There are various specifications such as 6 -person, 10 -person, 25 -person, and 42 persons.There is a high -speed inflatable system at the lifeboat, which can be carried by 15s after the inflation is started.

The lifeboat is usually closely packed and is collected in the partition compartment of the aircraft cabin exit.Under emergency conditions, take out the lifeboat and put it into the water from the open emergency cabin door.When the lifeboat falls into the water, the D -shaped pull ring is pulled, and the high -pressure gas cylinder is started to expand the ruthless puzzle (should be avoided in the cabin and the lifeboat can be expanded in the aircraft).The lifeboat is inflated and floated on the water, and you can use Lasula back to the emergency cockpit to board the Ship.After boarding the Ship, cut off, and the lifeboat broke away from the plane.The items and equipment on the lifeboat are generally the same as the slider -life raft.

3. Safe clothes

Lifetime clothing, also known as life -saving vest, is a kind of rescue clothing. It is designed with a vest that uses nylon fabrics or chlorine rubber, buoyancy materials or inflatable materials, reflective materials, etc.The bright color in the life jacket or the color with fluorescent ingredients can stimulate our optic nerve.This is related to the wavelength of this color. Human eyes are easy to accept and not easily confused by other colors.Wearing such a color life jacket is easy to be discovered in order to implement rescue as soon as possible.The useful life of general life jackets is 5 to 7 years. It has enough buoyancy to wear on the body so that the head of the water drop can expose the water.

Ship -for -life jackets and Ship children's life jackets are more suitable for life -coastal and inland people's life -saving life.The production of life jackets has strict requirements. It uses polyethylene foam plastic as the production material. After soaking in water for 24 hours, the buoyancy loss of life jacket should be less than 5%.In addition, there are shipwreck work life jackets, which are suitable for all kinds of people in the coast and inland river.

The inflatable life jacket is used when people and children fall into the water.Life clothes are usually strap, which are generally stored under the seat or the top of the cabin.In front of the plane, the flight attendant assisted passengers to put on a life jacket.Passengers pulled the inflatable switch before and after the departure, and the high -pressure carbon dioxide cylinder was ghostic to life jackets.The inflatable life jacket shows a U -shaped U -shaped, around the neck and chest, which can ensure that the water falling person's head is higher than the water surface, the face is upward, and the body and the water surface are about 40 degrees.Because the buoyancy of the life jacket is mostly distributed in the chest of the wearer.Therefore, it can produce sufficient torque and maintain good stability.When wearing a life jacket floating in the water, do not swim unless it is urgently needed, so as not to consume too much energy.

4. Inflatable lifeburn

The life ring is a kind of water life -saving equipment. It is usually made of cork, foam plastics or other light materials with smaller proportion, with canvas and plastic on the outer bread.The appearance is orange -red, which is convenient for water search and rescue. The minimum buoyancy in the working state is 8 kg.Put it on the waist when used.

5. Drowning automatic Lifeline

A micro -portable water life -saving equipment.It is composed of airbags and gas generators. Turn on the generator in time when used.

6. Lifeboat

Water life -saving equipment.Safe vessels located in natural swimming places such as seaside and lakes.Manipulated by life -saving personnel, swimming in his working scope, observing water conditions to prevent drowning and other phenomena.
