[How to save self -rescue at sea] How to save self -rescue and rescue methods on the sea of self -rescue at sea

How to save self -rescue at sea Self -rescue and rescue methods at sea

1 Generally speaking, it is not encouraged to jump first, because in the water, the body temperature of the human body is lost quickly, and it may be taken away by the water.Under the circumstances of environmental permission, you can skip the boat, pay attention to avoid the shallow beach reef.To quickly leave the shipwreck, if the Ship is covered, you must jump to the head of the bow.

2 Once the water falls, be sure to leave the hull quickly to prevent the vessels from being inhaled again.At the same time, you should raise your head to tilt your body.After maintaining this attitude for a few seconds, you can slowly float on the water with the powerful buoyancy of the life jacket.

3 Do not make unnecessary swimming after falling into the sea, to save physical strength and wait for rescue.

4 Creation of swimming will be rescued!When the Ship is sinking, the sucking power will be generated. Paralying, the place where the fluid is high at a high speed, and the sinking Ship is slightly stronger. Pressing people around the Ship, can't get out, and make people drown.

5 Self -rescue methods that do not swim: When sinking down, keep calm, close your lips, bite your teeth and hold your breath. Do not struggle in the water.Slowly float on the water.After floating on the water, do not lift your hand out of the water, and place it under the water to keep your head above the water surface so that you can breathe air.

6 The most important thing is to maintain physical strength. When someone comes to rescue, use the whistle and reflective equipment on the life jacket to attract the attention of the rescue staff.

Method for forced to drift on the sea

1 , Warm with your companions

When encountering the drifting condition, if the companions are around, they will match each other to warm the back to maintain the body temperature.

2 , Use the mirror reflection principle to create signals

Use metal items floating at sea as a reflector.The slightly shaking mirror allows the reflected light flash to intermittent, attracting the attention of search and rescue personnel.

3 , Avoid sunburn

Surviving on the sea, sunburn is a question worthy of face -to -face.We must avoid direct contact with the sun with the body, and try to find a paste from the first aid tools to isolate the damage caused by the sun to the Skin to prevent the occurrence of sunburn.In addition, the reflected strong light brought from the sun to the water surface is also a sunscreen element that cannot be ignored. Therefore, the head and eyes must be careful of the damage caused by such strong light.

4 , Avoid dehydration

Galmic (sea) may increase the occurrence of dehydration.To survive on the sea, in order to avoid dehydration, we should try to reduce the number of times to go to the toilet and keep ourselves in the body. If you feel uncomfortable, try not to make ourselves more comfortable by vomiting.

5 , Avoid the trouble of blindness and head damage

If you are infected with flames, cigarettes or other pollutants on the water, we must first wash the pollutants with salt water and then rinse it with fresh water.Eye cover18 to twenty four Hours, even longer.In order to avoid strong light from the sky and water harm your eyes, if you are prepared, wear Sunglasses to protect your eyes.

6 , Pain caused by salt water

Soaking in the body for a long time may cause the Skin wound, and the original blisters or scars on the body may be thick or torn again. At this time, in addition to avoid touching the wound, we must use fresh water to rinse it.EssenceIf possible, keep the wound dry and use the desiccant.

7 , Keep physical energy (1)

The loss of body fluid and exhaustion of physical strength will cause more damage.If you start to feel a halo, start vomiting, try to change the place, and stay away from vomit and smell.

8 , Keep physical energy (2)

Do not deliberately rely on exercise to maintain body temperature. Instead of deliberately circulating, the body temperature is easier to lose, and the exhaustion will make it easier for us to accelerate the temperature loss of the body in cold water.Maintaining buoyancy and using various kinds of materials is the best way to save self -help.

If the waves on the sea, if you do not wear water and lung Diving equipment, you may not be able to breathe at sea and the method, then according to the following practice:

Step 1: Take a deep breath.Step 2: Put your face in the water, close your mouth, stretch your arms forward, and relax.Step 3: Keep this posture rest.Step 4: Looking out of the water, stepping on the water, and venting the head into the water.Such a cycle.

9 ,keep Calm

Keep your head calm, do not shout without any help, and do unknown and physical action.

1. How to use the lifeburn circle

Most of the falling water accidents are sudden, and water rescue is actually Running against time.In emergency situations, when some people fall into the water or flood disasters are trapped, the golden time of water rescue is only a few minutes, and the water falling and rescuers need to understand the correct use of the life circle in order to rescue more quickly.

1. The throwing person holds the lifeblood of the lifebuilding circle in one hand, and throws the lifebing circle in the lower direction of the waterfall person. When there is no flow and the wind should be thrown in the upper wind, so that those who fall into the water can climb the water. Be careful not to hit the water.It can also be tied to the railing by the railing, throwing the life circle with both hands.

2. If someone does not fall into the water during sailing, the water dropper should call loudly to attract the attention of other people.The discoverers should get the lifebuilding circle nearby and quickly throw them towards the sea near the waterfall. The specific method is to leave the life circle to the water fall.Those who fall into the water first grab the handles, then press the side of the life circle with both hands at the same time, so that the lifebuilding circle is erected, the hands and heads are in the circle, and then the life ring is sandwiched under the two armpits, keeping the head higher than the water surface.The body floats in the water, waiting for rescue.

3. If someone falls into the water during the mooring of the Ship, it is best to leave the life ring with floating cables at this time.After the falling water was climbed, the staff on the boat recovered the floating cable and pulled the falling water to the edge of the boat.

2. precautions for the use of lifeblocks

1. storage of the lifeburn

The Lifeline should be separated from the two -side side of the Ship, and there should be at least one stern; it should be able to remove it quickly and not to be permanently made.

2. The custody of the life circle

The life circle is stored in open -air, and it is easy to damage. When storage, you should pay attention: often pay attention to whether the appearance is cracked, whether the hand is worn or mildew, and whether the buoyancy material is aging;Rust removal and paint should be repaired in time.

3. precautions for Safety Circle Safety Circle

The life of the lifebuilding circle should be correct; the life of the lifebuilding circle cannot be hit to the water; pay attention to the use of the life circle that is not allowed to be used casually; check every three months.

4. Regulations on the management regulations of the life circle inspection and maintenance

The sailor chief (or the designated person in charge of the platform) counts the number of life circles per week (before the typhoon comes), and check the reflective band, self -light and ropes on the life of the lifebing circle.Supervision for replacement.If you find loss and damage, report safety supervision immediately for supplementary and maintenance; reflective bands fall off and paste immediately.The self -lighting Lights of the lifebuilding circle shall be checked by the sailor chief during each dynamic period.Performance; if the battery enters the moisture, the battery will gradually fail, so you cannot pull the water in the water at will.

Having a sailing boat means to have a city -state that lives independently and freely at sea; with a sailboat, you can enter a port of any port on the sea ...Some people who get up are not an excessive price.However, so far, the sailboat is still a game that is only played by a small number of people in Mainland China.

1. Sailing equipment

As the so -called work is good, we must first benefit its instrument.When it was really going to sea, there was no professional sailing equipment.Due to its special environment, the sailing movement needs to be armed throughout the body.Sailing clothes, ropes, sunscreens,Sunglasses... Every detail may affect your progress of learning to control sailing.Therefore, don't forget to check the equipment before boarding the Ship.

Voyage

The weather on the sea is easier to change than the shore, so it is very important to wear and equipment correctly in this sport.You don't have to spend a lot of money on the equipment. Here is some simple guidance for your basic equipment:

Wear loose clothes.It takes a lot of movements to operate the sailing boat, so wearing can give you enough clothes for you

Carry extra clothes in luggage Bags.In order to add clothes or wet water when cold, you can change your clothes.

Wear light and breathable clothes in hot days.It is best to wear light -colored clothes. The clothes you lead can protect your neck from exposed to sunlight. The clothes with long sleeves can protect your arms from exposed to sunlight.

Use sunscreen (SFP15 or higher) to protect your Skin, and even so on a cloudy day, it is best to apply it frequently.

Wear a hat to protect your eyes and make your head from being shined with sunlight.In cold days, wearing a hat can warm the head.

Wear Sunglasses (at least 90%).Polarized mirrors can greatly reduce the dazzling feeling of water.

You must wear anti -slip shoes.In order to stand on the slippery deck.tennis shoes that are not broken sole will be a good choice. Of course, sailing shoes are the best choices, because the soles of the sole

The rubbing force is very large and dry very fast.Don't wear sandals or other toe shoes, sooner or later you will hurt your toes.

waterproof navigation boots will keep your feet warm and dry in cold days.

Daihang sea gloves can prevent your hands from being scratched and increase friction.It is best to wear waterproof gloves in cold days.

Lifeline is a must -have equipment for navigation.The life jacket should be fitted and has quality assurance.

Wear a few more layers in cold days.When you feel cold, your operation skills will be greatly affected, so wearing a few more clothes is a wise choice.Avoid wearing cotton clothing, wear

Clothes that can still keep warm after wet, such as cortex or polyester fiber clothing.Dedicated cold prevention clothing, dedicated cold -proof clothing can keep you warm and dry in bad weather.There are several styles to choose from:

Standard two -piece set, including a waterproof jacket with a hat pocket and an independent suspender pants.

Conjusational clothes will make you more dry, but you cannot take off your shirt or pants alone to adapt to changes in temperature.

On some particularly humid ships, crew members often wear wet warm clothes similar to divers.

Dry -style warm clothing is a suit that allows you to isolate water. They seal your neck, wrist and ankle tightly.They can prevent water and keep warm.

Safety equipment

In addition, there should be complete safety equipment on the sailing.Safety equipment not only protects Ship equipment, but also protects individuals. The crew must know the location and correct use of these equipment in order to prevent accidents during the movement.Sailing needs to prepare the following safety equipment on sailing on the shore:

Safe vests -Each person must have a qualified life -saving vest, and children must prepare special size life vests for them.

Life Rings -placed on the Ship that is easy to get on the boat, and once someone falls into the water, it can quickly throw it into the water fall.

FIRST AID Kit -Applicable first -aid drugs and items.

Bilge pump -manual or electric pump, which can quickly discharge the chamber water.

Bucket (bucket) -The rope of about two meters can be used urgently when the cabin is in water.

In addition to the above, if you want to travel long, you can also prepare excess anchor cables, waterproof flashlights, fire extinguishers, Gangpu, Haitu, signal bullets, wide -leaf short paddle, drainage equipment, horn, compass, sufficient water, knife, pliers, pliers, Screws, rolls and other tools to prepare from time to time.

First boarding

For the first time to board the Ship, pay attention to boarding etiquette. First of all, the captain's consent can only be boarded, just like invited to enter the house of others.When boarding the Ship, you should be very careful, especially when you are low tide, use a ladder or connect to the large boat by a small boat or a small boat. When crossing the side cable, you should cross the back to maintain the center of gravity of the body.Proper locations and prevent the hull of the hull may move into the water.

The sailing club often keeps tilting or suddenly unpredictable, especially for beginners who are not accustomed to activities on the tilted Ship.The string cable, the top pole of the cabin, or any fixed devices on the Ship can help you stand firm.When walking around, the body is slightly bent and walks, keeping the center of gravity, and be careful not to hit the horizontal pole or let it hit you.Walk on the deck to keep on the upper side for safety.

2. Small boat site and instructions

1. Former sail (jib): sail used in front of the main mast.

2. HeadStay or Forestay: The top of the mast can be pulled forward to the front boat, and the steel cable on the front sail can be buckled.

3. SHEET: The main control of the rope can be released or tightened and fixed. This picture refers to the front sail.

4. Mainsail: The largest sail that is raised after the main mast is also the source of the main power of the entire sailing boat.

5. Battens: The flat bars inserted from the back edge of the sail, in order to maintain a good sail shape.

6. MainSheet: Rope to control the angle of the main sail.

7. Boom: elongated, used to fix the bottom of the main sail.

8. BOOMVANG: The cable tightened or supported by the sail truss to prevent the sailing truffle up.

9. Mast (MAST): The long rods made of wood or aluminum are supported by steel cables for lifting and stretching sails.

10. SHRouds: The tension used to fix the side of the mast.

11. Centerboard: Under the hull, you can adjust the depth of water (mainly axis -based heart, front and rear lift).

12. Rudder: The device used to control the Ship in the direction.

13. Boat (BOW): The front of the hull.

14. Stern: The last part of the hull.

15. Hull: The shell of the Ship.

3. Preparation before playing sailing

1. Operation basis

(1) Look at the basic knowledge of sailing, understand what the sailboat is driving, and see the relationship between the wind, sail and boat in all directions, see the basic chapter of the sailboat in the forum technology post.

(2) Keep in mind the basic guidance and safety reminder of the teacher before launching. Sailing is a sports Tool with safety knowledge, including wearing a life jacket to understand the use of safety equipment. Pay attention to the difference between the boat and the big boat from the preparation of the Ship on the dock.To control the balance of the boat and your own center of gravity, it is generally necessary to quickly move the Ship to move the center of gravity to the center of the Ship to avoid the boat cover.Check whether each rope is in normal state.

(3) After boarding the Ship, pay attention to lift the sails because of the cooperation, and the boat can generally rise on the shore.

(4) After sailing, safely leave the dock.To judge the direction of the wind first, you can generally judge through the wind direction indicator on the boat or the wind line tied to the side branches. Generally, the range of 45 degrees in the direction of the wind is the range of 45 degrees.Sailing, of course, to adjust the angle of sails from the perspective of wind.

(5) After a period of familiarity, we can master the basic operation of the former sails, and start learning how to take the helm. The boat we learn is the rudder of the pushing rod. It is more sensitive than the rudder wheel.Basic driving in turn to understand the relationship between wind, front sail, main sail, main sail, Ship's order and rudder's sense of rudder, and can basically understand the basic essentials and feelings.

2. Important angle

(1) Wind direction angle: The term for sailing motion sailing, refers to the angle between the wind between the end of the same sailing boat.The motivation of the sailing Ship mainly depends on wind power.And the size of the wind direction to the promotion of sailing is very important.Athletes must correctly grasp the wind direction and angle in order to fully use the wind to drive sailing.

(2) Different wind direction angle divide the degree

The wind direction angle of the top wind is between 0 degrees and 30 degrees; the wind direction angle of the front wind is between 30 degrees and 60 degrees;At 80 degrees 1 100

Between degree; The wind direction angle of the Smooth wind is between 100 degrees and 170 degrees; The wind direction angle of the tail wind is between 170 degrees and 180 degrees.

3. Sailing knot

Since ancient times, skilled use of knots is one of the very important sailing skills, because it will save the life of the crew.Different use cables use different materials.Due to the high tensile strength, nylon rope can be used as anchor rope or a boat rope.Dakun has little resistance and can be used as a flag rope or main sail.Polypropylene can float and can generally be used as a tie rope.

(1) Single knot.The wide range of uses can prevent loosening.

(2) Lilac knot.It is not a very strong way of knotting, which can be used as a short -term link.

(3) 8 -character knot.Used for the top of the flag rope or main sail.

(4) Rolling knot.Used to connect with coarse cables.

(5) Horn knot.Used to connect the cable angle of the same system.

(6) Two halves.Used for the same column, ring, etc.

It is also important to exercise the skills to handle cables.First of all, take the cable carefully.Before handing, the disk is divided into two parts.When throwing the smaller part of the cable, you need to keep the hand shape so that the other half of the cable is naturally pulled out in the other hand.

[Life Products] What are the pools of life supplies in the swimming pool? Detailed explanation

What are the swimming pool life supplies?

swimming pool life supplies are used for the equipment used in swimming pool life. It mainly includes swimming pool life chairs, life -saving rings, life -saving hooks, life rods, life jackets and life ropes.

Among them, the high chair made by the lifeguard -life -saving chair: It is a dedicated seat for a lifeguard to observe the swimmers from a height, also called a life -saving watch chair.There are two types of materials: 202 stainless steel and 304 stainless steel.There are two types of heights: 1.9 meters and 2.5 meters.

Life Circle:One is the bubble Swimming ring, which is used by children or those who begin to swim.Generally, the diameter is 60cm, the shape is cute, and the color is bright.The other is a professional life -saving circle. It is a kind of water life -saving equipment. It is usually made of cork, foam plastics or other light materials with smaller proportion of light materials.High and low temperature, no shrinkage, rupture, expansion, and decomposition.The color is generally orange, with clear eyes, and there are four reflective cloths. There are four holes for crossing the rope to facilitate the life of the shore.The iron blocks with no less than 14.5kg in freshwater reaching 24h.

Relief rod:The Lifeline rod is composed of a life hook and a telescopic rod. When there is a drowning of the swimming pool, the lifeguard can use the life hook to hook the drowning person to the pool to rescue the shore quickly on the shore.

life jacket: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.design the standard of the buoyancy of the life jacket.Generally, the life jacket is equipped with straps in front and behind, suitable for any body -shaped customers. Generally, the buoyancy is greater than 7.5 kg.

Life Rope:The material of the life rope is polycatis fiber cloth (waterproof and wear -resistant material).The rope can float on the water.At the time of use, one end is tied to the life circle, the other end is fixed on a firm object, loosen the rope and throws the lifebing circle away from the rescue, and then pulls it back to the life circle and people through the life rope.

What is the size of the life circle

The specifications of the lifebuilding circle are required, the lifebuilding circleThe outer diameter should not be greater than 800, and the inner diameter should not be less than 400.1.5kg Children's Life Circle size is 510*340*90 (mm); 2.5kg adult life -saving circle size is 720*440*105 (mm); 4.3kg adult life ring size is 760*440*105 (mm).The periphery of the life ring should be equipped with a cable cable with a diameter of not less than 9.5 and not less than the outer diameter of the life ring.This cable should be tightly tightened in the four distances around the circle and forms four equivalent rings.

Technical requirements for life -saving circle

1. There is an outer diameter of not more than 800mm and an inner diameter of not less than 400mm.

2. Made of natural buoyant material, its buoyancy shall not rely on lamp -hearted grass, cork plane slices or cork particles, any other loose granular materials or any air room dependent on inflatable.

3. The iron blocks with no less than 14.5kg in freshwater reaching 24h.

4. It has the quality of no less than 2.5kg.

5. Falling the fire is completely surrounded by 2S, not burning or continuing melting.

6. Its structure should be able to withstand the height or 30m (taking the big) from the storage position to the lightest carrier.

7. If the lifebuilding circle is equipped with a spontaneous smoke signal and a rapidly throwing device with a self -lit light, it should have the quality that is sufficient to operate the rapid throwing device.

8. There are 1 handle cable with a diameter of no less than 9.5mm and a length of no less than 4 times the outer diameter of the life ring.The handle cable should be around the life circle and fix it at 4 equal points to form 4 equal rings.

9. The life of the life of the river waters is not less than 1.5 kg. The purpose is to enhance the intensity of the life of the life of the life, and to the accurate throwing when the rescue falls, it is not affected by the wind and waves.

What are the belongings of the lifeburn circle?

1. Self -light floating light

Each Ship at least half of the life circle should be equipped with a self -lit light that meets the requirements of the rules so that it can display the location of the lifebuilding circle and its users at night, which is convenient for searching for rescue.At present, the self -bright floating Lights on the Ship are mainly used as the power supply.Once the life ring is put into the water, the bright floating light is automatically floating on the water surface, and a white flash emits.

2. Smooth smoke signal

There are at least two life -saving circles near each Ship's cab. At least two have spontaneous smoke signals that meet the requirements of the rules. When the lifebuilding circle is thrown, the smoke can floats on the water with the life circle and emits orange -yellow smoke.

3. Floating Life Covers

At least one life ring of the Ship should be attached to the requirements that meet the requirements. The length is generally thirty meters, or twice the distance from the Ship's light load water line to the storage area. The two are large.

Safe Circle price and Selection skills

1. Qualified life -saving circle products shall have relevant material inspection reports, type test reports and Ship embolism inspection certificates.Although there are very few complaints caused by quality problems in the life circle, any regular product should have basic elements such as factory names, factories, qualification certificates, and production date.At the same time, it should be operated in accordance with the relevant quality standards, and the use instructions of Chinese words should be attached.Because the lifebuilding circle is a special life -saving equipment, you must keep your heart when you buy it to avoid brewing during swimming.

2. At present, the reference cost price of the domestic qualified life -saving circle products is: about 55 yuan/piece of polystyrene clothing cloth, and about 100 yuan/piece of citrine polyethylene lifebirth circle.Therefore, the life circle with too cheap prices is likely to be a product that cut corners and should be purchased with caution.

3. Under the condition of conditions, the merchants are required to conduct necessary verifications of the weight of the life of the life circle, stitching quality, strength, floating, high temperature resistance, and resistance to damage in accordance with the standard requirements of the standard specifications.

What are the differences between lifeburn and swimming rings

Swimming ring: It belongs to water toys, with light weight, prone to damage, leakage, poor pressure resistance, and explosion.The plastic surface is slippery when water is wet, and it is difficult to grasp.It can only play auxiliary or protective effect in water leisure movement, and bring to the danger of deep water in the deep water area.

Life Circle: One of the water life -saving equipment, the production process is complicated, and the requirements are stricter.The rim core material uses a closed -hole foam material, that is, the polystyrene material, wraps the glass fiber cloth outside, is also applied to three layers of phenolic resin, and then the sails are covered with several layers of paint.The life of life must have fluorescent strips for convenient rescue.

Not a lifebuilding circle, you must not be used as a life settlement.The national standards performed by the swimming circle are different from the national standards performed. The lifebuilding circle is a life -saving function. It has many accessories; while the Swimming ring is defined as a water toy, it is only the toy standard.Therefore, compared with the real lifebuilding circle, the toy swimming circle is prone to damage the air leakage, the pressure resistance ability is very poor, it is easy to explode, the plastic surface is slippery, it is difficult to grasp the grip.Auxiliary or protection is dangerous if it is taken to the deep water area.

How to use the life circle

1. Soak in the water temperature of 30-40 degrees before the life ring is used. The plastic softening of the life ring and the air inside can only be used after the water temperature.

2. Do not charge too much when the life ring is inflated, because the current indoor temperature is limited, and if it is too full, all of them are cold air. Once put in the hot water of the swimming pool, the life ring will be full due to inflatable heat and swelling.The principle of cold contraction burst at the interface.
