The issue of safety on the water is in the first place for any owner of a floating craft, whether it is inflatable. PVC boat Or a full-boat. Life jacket It's not just a formal attribute, it's a vital piece of equipment that can keep you alive in a critical situation. Many water-engineers mistakenly believe that swimming relieves you of the need to wear personal protective equipment, but accident statistics suggest otherwise.
In cold water, even an experienced swimmer can lose the ability to move due to cramping or heat shock. life-saving In this article, we will discuss how a life jacket differs from a safety jacket, how to choose the right size and what GIMS requires.
Key differences between life jacket and insurance
The first thing to understand when buying equipment is the fundamental difference between a life jacket and a safety vest. Life jacket The Life Jacket is designed to keep people on the surface of the water even when they're unconscious, and it's designed to automatically turn the body upside down, allowing them to breathe freely, and it's usually a volumetric foam insert or an automatic inflatable system.
At the same time, safety-jacket Buoyancy Aid, or as it is often called, the unloading vest, is designed only to facilitate swimming and protect against impacts, it does not turn a person unconscious and does not guarantee survival in a storm. 50N or EN ISO 12402-5They're not suitable for use as the primary means of rescue in open water.
The choice between these two types depends on the use scenario: if you plan to actively raft or ski in warm water near the shore, the safety option is suitable. life jacket with a buoyancy of at least 100NThat guarantees security.
⚠️ Attention: Never use fishing unloading bags as a replacement for a full life jacket, which is not buoyant enough to keep a person afloat in clothes.
GIMS requirements and legislation
According to the current rules of the Russian Federation, the availability of life-saving means on a small vessel is mandatory. GIMS MOE The number of life jackets should be consistent with the number of people on the boat plus one spare, which means that if two people are on the boat, they should have at least three.
It is important to note that vests must not be just “in a hazelnut” somewhere, but in an easily accessible place. The rules require that every passenger be able to quickly wear a rescue device. The GIMS inspector, when checking documents and equipment, first of all pays attention to the presence of tags with markings and certificates of conformity.
- 🛡️ Vests must have a valid certificate of compliance with the Technical Regulations of the Customs Union.
- 👥 The number of vests is equal to the number of passengers + 1 spare copy.
- 📍 Rescue products should be placed in an accessible place, not packed in seals at the bottom.
Buoyancy classes and vest marking
The international classification divides life jackets into several classes depending on their buoyancy as measured in Newtons (N). Understanding these classes helps to choose the right gear for specific swimming conditions. The higher the class, the more support on the water and the more severe the conditions can be used vest.
The 50N class (ISO 12402-5) is a safety vest for protected waters where help is nearby and a person knows how to swim. The 100N class (ISO 12402-4) is designed for calm waters where quick rescue is expected; such vests can flip some people on their backs, but do not guarantee this for everyone. The 150N class (ISO 12402-3) is a universal standard for open water that provides a reliable face-up position even in clothing.
| Class (N) | Type of water | Features | Recommendation |
|---|---|---|---|
| 50N | Protected (pool, beach) | Not flipping. | Sport, training |
| 100N | Calm (rivers, lakes) | Partly flips. | Fishing by the shore |
| 150N | Open (sea, reservoir) | Guarantees a face-up position | Long-distance hikes |
| 275N | Extreme conditions | For working in heavy clothing | Professionals |
For PVC boat owners, the 150N class is often the best choice, as it provides a balance between comfort and safety. Inflatable vests This class is compact in a deflated state, which is important in the limited space of an inflatable boat.
How to check the buoyancy of the vest yourself?
At home, it's hard to test for accurate buoyancy, but you can do a rollover test. Go in the chest water, put on your vest, relax your muscles and raise your legs. A good life jacket should turn you face up and keep your mouth above the water. If you have to work your feet or throw your head back to breathe, the vest doesn't do its job as a lifeguard.
Materials: Foam or Inflatable models?
The choice of material filler is a matter of personal preferences and operating conditions. Foam vests They're maintenance-free, they're puncture-free, they're always ready to go, they're always buoyant, they're often brightly colored for visibility, but they're very bulky, they can restrict movement when rowing, and they can lose properties over time when they're not stored properly.
Inflatable vests (CO2) is compact, convenient for active fishing or rowing, as it is almost not felt when deflated; they act automatically when in contact with water or by hand via check. The main disadvantages are the need for regular checks of cans and mechanisms, as well as the risk of damage to fabric. For anglers who spend a lot of time in a boat, inflatable models are often preferred due to the lack of restraint of movement.- 💧 Foam models do not require pumping and maintenance of the mechanism.
- 🎈 Inflatable models are compact and do not interfere with active actions.
- 🔧 Inflatables require annual replacement of the capsule and valve inspection.
If you choose an inflatable vest, be sure to buy a set of spare cans and automatic-fire pills. Store them in a sealed bag along with the vest so they are always on hand.
Rules for selection of size and fitting
The wrong size is one of the main reasons for the ineffectiveness of the lifeguard. The vest should not hang around, but should not squeeze the chest, making it difficult to breathe. When fitting, be sure to fasten all your belts and have someone pull your shoulders up. If the vest rises easily above your ears or chin, it is small or poorly tightened, which is dangerous, because when falling into the water, it can "go away" on your face.
Pay special attention to the adjustment belts. Webbing system It should allow the vest to be tightly fixed on the body. For children, there are special models with additional straps between the legs (crotch straps) that prevent the child from slipping from the vest. Adult models for extreme skating can also have this option.
⚠️ Attention: Don’t buy a growth vest for your child; at a critical moment, your child may just slip out of a too large neck, even if the sides are zipped.

Care, storage and maintenance
Life jacket life is limited, even if it looks whole visually. The foam fillers absorb moisture over time and lose their buoyancy, the fabric burns out and becomes brittle. Inflatable systems Require regular CO2 replacement of cans and automatic capsules (usually every 1-2 years or after each use) and store vests in a straightened form, in a dry, cool place, protected from direct sunlight.
After each release, especially if it comes into contact with salt water, the vest must be rinsed with fresh water and dried. Mud and salt destroy tissues and machinery. Periodically check the seams for discrepancy and integrity of the belts. If the vest has been in water and wet inside (relevant to some types of foam), it must be thoroughly dried before packaging, otherwise mold will start inside.
The average life of a foam vest when used actively is 5-7 years, after which the foam can lose up to 30% of its buoyancy, making its use dangerous.
Frequently Asked Questions (FAQ)
Can I use a baby vest for an adult if it is tightly fastened?
No, absolutely not. Baby vests are designed to fit the child's body proportions and have less buoyancy, they can't hold the weight of an adult, and in case of danger, they can slip or burst under load.
Should I wear a vest if I am sitting inside a boat and I don’t plan to go swimming?
Most accidents happen when people don't expect to fall, whether it's a sharp maneuver, a collision with a wave from another vessel, or a sudden gust of wind, and there may not be time to put on a vest in the water.
How often should I change the canister in an inflatable vest?
The container changes after each operation or every 2-5 years (depending on the manufacturer), as the metal can corrodate. Automatic tablet (hydrostatic element) is changed strictly after the expiration date indicated on the package, usually 2 years.
Does GIMS allow the use of homemade life-saving appliances?
No, the rules require that life-saving appliances have a certificate of conformity and marking, that home-made structures made of foam or canisters will not pass inspection and, most importantly, do not guarantee safety.
