Is there a life limit for life jacket?

The life jacket has a limited use period. If it continues to be used more than the period of use, the effect of life jacket will be greatly reduced. Generally speaking, the life of the life jacket is as follows:

1. The use of buoyancy materials to fill the life jacket is 5-7 years, and the storage period is 10 years.

2. The use of inflatable life jackets is 3 years, and the storage period is 8 years.

Life -care clothing maintenance method

1. Make sure that life jackets are worn correctly.

2. The life jacket needs to be stored in a clean, cool and dry place.

3. If the life jacket is humid or rainy, it cannot be dried directly under the sun, and it should be dried in a cool place.

4. Wash the life jackets regularly with fresh water, especially the life jackets have been used in the seawater environment.

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.

How to buy a life jacket

1. Look at the 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.

2. Look at accessories

There are two types of life jacket accessories. One is the survival whistle. This is basically standard for life jackets. The other is reflector. If it is operating at sea and the visibility is low, we are strongly recommended to standard.If it is generally playing leisure and entertainment, it is generally not worthy.The life jackets of Big fish also attach many functions, such as pockets, fish tongs, sub -pockets, and so on.However, some of the life jackets are required. No matter how the style changes, these are not missing. This is the life pocket and insurance Belt (through the Belt connected to the front film from the back of the life jacket).

3. Look at buoyancy

The buoyancy of life -saving clothing should meet the prescribed standards (continuous soaking in seawater for 24 hours of buoyancy should not be less than 0.75 kg. The front and rear pieces of life jackets must have the correct proportion.The buoyancy is regarded as 1, and the buoyancy of the front film should be greater than 0.58).However, the buoyancy will change as the buoyant time in the water will change at about 5%.. Strong buoyancy, folding is convenient to collect in life jackets, and it is easy to dry. More importantly, the buoyancy is soaked in the water for a long time, and the cutting force is significantly reduced significantly.

4. Look at the reinforcement situation

Two methods are commonly used for life jackets.The first: rope, this kind of life jacket is generally a low -suspected life jacket.This is used in early life jackets.The second is zipper buckle. This kind of life jacket is the most widely used now.
