Be careful, ice!
The first ice only looks strong, but in fact it is thin, weak and cannot withstand the weight of not only an adult, but also a child. Therefore, do not rush to go out on the thin ice of reservoirs. It is necessary to wait until the ice becomes thicker and stronger under the influence of frost.
Slide 3
Failure to follow this advice may result in failure on the ice. Unfortunately, help for those in trouble on the water sometimes comes too late and the incident ends tragically. To prevent this from happening, you must remember that going out on the autumn ice is only possible as a last resort and with the utmost caution.
Slide 4
In all cases, before leaving the shore on the ice, you must carefully look around, outline your route, choosing safe places.
Slide 5
You should be wary of places where the ice is covered with snow: under snow, ice grows more slowly. Sometimes it happens that throughout the entire body of water the thickness open ice- 10 cm, and under the snow only 3 cm.
Slide 6
You need to know this! Ice that is at least 10 centimeters thick in fresh water and 15 centimeters in salt water is considered safe for humans. The strength of ice can be determined visually: blue ice is strong, white ice is 2 times less strong, grey, matte white or with a yellowish tint, ice is usually spongy and porous and unreliable. Such ice collapses without a warning crack.
Slide 7
Required Ice Thickness
Single pedestrian - at least 5 cm Single pedestrian with a load - at least 7 cm Group of people (distance between people at least 6m) - at least 7-9 cm Bus (without passengers) - at least 40-60 cm Tractor - more than 60 cm
Slide 8
It's dangerous to walk
On ice covered with snow (snow falling on newly formed ice, in addition to masking polynyas, slows down the growth of the ice cover) Ice is thinner in currents, especially fast ones, in deep and windy places Above shady and peaty bottoms In swampy areas shores In places where underwater springs emerge Under bridges
Slide 9
In narrow channels Near places where warm and hot waters from industrial and municipal enterprises are discharged into reservoirs In places where reeds, reeds and other aquatic plants grow, the ice is thinner. Ice in the downstream of the dam, where even in severe frosts, short-term releases of water from the reservoir can drain the ice and form dangerous gullies in it. If the air temperature remains above 0 degrees for more than three days, then the ice strength decreases by 25%.
Slide 10
Crossing the pond safely
On transparent ice with a greenish or bluish tint and a thickness of at least 7 cm. Before moving on the ice, you need to make sure that it is strong. To do this you need to use a hard stick.
Slide 11
When moving across a frozen body of water, use a pole (stick) to hit the ice in front and on both sides of you several times in the same place. If after 2-3 blows no water appears, then the ice is reliable. If the ice breaks through and water appears on it, you need to immediately stop and turn back, but without rushing and trying to walk without lifting your feet from the ice (sliding steps). When moving back, continue to check the ice with a pole.
Slide 12
Strictly prohibited! Test the strength of ice by hitting the ice with your foot - in this case you can immediately fall into the water. It is not allowed to cross the pond alone, because... If you fall through the ice, you can’t expect help from anyone. It is also undesirable to walk on ice in the dark. Skating, sledding, and playing hockey on thin, fragile ice is strictly prohibited. Preparing ice for skating must be done very carefully. The thickness of the ice must be at least 12 cm, and for mass skating - at least 25 cm. It is not recommended to skate on frozen ice alone.
Slide 13
Rules of conduct on ice Under no circumstances should you go out on the ice at night or in poor visibility (fog, snowfall, rain). When crossing the river, use ice crossings
Slide 14
Rules of conduct on ice When forced to cross a body of water, it is safest to stick to the beaten paths or follow an already laid ski track. But if they are not there, before going down onto the ice, you need to look around very carefully and outline the upcoming route. When crossing a pond in a group, it is necessary to maintain a distance of 5-6 m from each other.
Slide 15
Rules of behavior on ice It is better to cross a frozen river (lake) on skis, in this case: unfasten the ski fastenings in order to quickly remove them if necessary; Hold ski poles in your hands without looping them around your hands, so that in case of danger you can immediately throw them away. If you have a backpack, hang it on one shoulder; this will make it easy to free yourself from the load in case the ice collapses under you.
Slide 16
Rules of conduct on ice When going to a frozen body of water, you must take with you a strong rope 20–25 meters long with a large blind loop at the end and a weight. The weight will help to throw a rope to a comrade who has fallen into the water; the loop is needed so that the victim can hold on more securely by threading it under the arms. Do not let children go on the ice (fishing, skiing or skating) without supervision.
Slide 17
Rules of conduct on ice It is very dangerous to slide onto ice from steep banks in an unfamiliar place. For skating, skiing and sledding, you need to choose places with solid ice cover that have been inspected by adults. Particular care must be taken on ice if there is a thaw during winter days. Where just a few days ago it was possible to skate on ice without danger, during the thaw days it is very dangerous to do so.
Slide 18
What to do if you fall into cold water:
Slide 19
If your help is needed: Arm yourself with any long stick, board, pole or rope. You can tie scarves, belts or clothes together. You should crawl, spreading your arms and legs wide apart and pushing the life-saving equipment in front of you, and carefully move towards the ice hole.
Slide 20
If your help is needed: Stop a few meters away from the person in the water, throw him a rope, a piece of clothing, or give him a stick or pole. It is unsafe to give a hand to the victim, since by approaching the ice hole, you will increase the load on the ice and not only will not help, but you yourself risk falling through. Carefully pull the victim onto the ice, and together crawl out of the danger zone. Without sudden movements, crawl away in the direction from which you came.
Be careful and remember: strict adherence to the rules of behavior and safety measures on ice will save your life!

Accidents do happen on ice. often due to non-compliance with the rules. A broken ice floe, cold water, and fast currents threaten death. Not even every adult can get out of a cold hole.
Be careful, attentive and
remember:
Rule #1
Never walk on the ice alone, unaccompanied by adults, do not play pranks or play around on the ice.
Rule #2
Avoid areas where the ice may be thin
Where streams flow or springs gush
Near bushes, trees, reeds
Under the snowdrifts and near the shore
Where are some objects frozen in the ice?
At plants and factories
Rule №3
Before you step on the ice, look for a well-trodden path or fresh tracks. If there is, then it is better to move along it, since this path has already been tested.

Safety measures and rules of conduct on ice
Slide 2
Today we will tell you: How to minimize the risk of being on ice; How to feel confident on it; How to avoid getting into unpleasant situations on ice. And also: What to do if you still fall through the ice; How to help the victim.
Slide 3
With the onset of the first frost, when the water in rivers, lakes, ponds and other bodies of water becomes covered with ice, the period of freeze-up begins. We must not forget about the danger that freshly frozen bodies of water pose. The first ice only looks strong, but in fact it is thin, weak and cannot withstand the weight of not only an adult, but also a child. Therefore, do not rush to go out on the thin ice of reservoirs. It is necessary to wait until the ice becomes thicker and stronger under the influence of frost. Failure to follow this advice may result in failure on the ice. Unfortunately, help for those in trouble on the water sometimes comes too late and the incident ends tragically. To prevent this from happening, you must remember that going out on the autumn ice is only possible as a last resort and with the utmost caution.
Slide 4
The strength of ice can be determined visually: Blue ice is strong, 2. Ice white– strength is 2 times less than 3. Ice that is gray, matte white or with a yellowish tint is dangerous.
Slide 5
Safe ice thickness for crossing a reservoir on ice: for lonely pedestrians - - - - - - - - - - - - - - - - 10-12 cm; for a group of people - - - - - - - - - - - - - - - - - - - - - 15-20 cm; for setting up skating rinks and sledding - - - - 25 cm. Particular care must be taken when the ice is covered with a thick layer of snow.
Slide 6
This is necessary to know.
It is dangerous to walk on ice covered with snow (snow falling on newly formed ice, in addition to masking polynyas, slows down the growth of the ice cover). The ice is thinner in currents, especially fast ones, in deep and windy places; over a shady and peaty bottom; near swampy shores; in places where underwater springs emerge; under bridges; in narrow channels; near places where warm and hot waters are discharged into bodies of water from industrial and municipal enterprises.
Slide 7
In places where reeds, reeds and other aquatic plants grow, the ice is thinner. Ice in the downstream of the dam, where even in severe frosts, short-term releases of water from the reservoir can drain the ice and form dangerous gullies in it. If the air temperature remains above 0 degrees for more than three days, then the ice strength decreases by 25%.

Slide 9
If you go winter fishing, you must follow the following rules:
It is necessary to know well the body of water chosen for fishing in order to remember where its depth is no higher than a person’s height or where from a deep place you can quickly get to the shallows leading to the shore. It is necessary to know about the conditions of formation and properties of ice during different periods of winter, to distinguish between signs dangerous ice, know the safety precautions and follow them at all times. Determine the route from the shore.
Slide 10
When winter fishing, think about safety first and only then about the catch!
Slide 11
If you fail, what should you do? The main thing is not to lose your composure! It must be remembered that even a poor swimmer is able to stay on the surface for some time due to the air cushion formed under the clothes.

REMEMBER!
Every second of being in icy water works against you: even 10-15 minutes of being in water is life-threatening.
Slide 12
Do not panic! Call for help. Do not dive headlong under water!
Slide 13
Extend your arms and try to get rid of excess weights. Do not make sudden movements - do not break off the edge.
Try to move to the edge of the ice hole where the current will not carry you under the ice.
Slide 14
Try to lean your chest on the edge of the ice with your arms thrown forward, try to get out onto the ice.
As soon as most of your body is on the ice, roll onto your stomach and crawl away from the edge of the ice hole as far as possible.
Get out in the direction you came from, because there is proven ice there.
Accidents do happen on ice. often due to non-compliance with the rules. A broken ice floe, cold water, and fast currents threaten death. Not even every adult can get out of a cold hole.

Safety rules on ice The presentation was prepared by teacher L. B. Barantseva
Rules for safe behavior on ice When going out onto a body of water, you must not test its strength or hit it with your foot or any object. Because the ice is already melting and can break under your feet. If there are adults nearby, they can check the strength of the ice by eye. This is not difficult - the color of the ice is blue, which means it is still strong, but when it is white, it is already dangerous, because its strength has decreased by 2 times.
Rules for safe behavior on ice When a grayish or matte tint appears on the ice, it is very dangerous to go out on such ice. Ice that is more than 10 cm thick is considered safe. Ice of this thickness can support both a child and an adult without breaking. Don't forget about the cracks and holes; it is in these places that the ice is not at all strong. And if you hear the ice cracking under your feet, there is no need to panic, make sudden movements or run. You need to calmly, slowly lie down on the ice and try to crawl or roll to a safe place
What should you do if you fall under ice? Try to call adults for help. Before adults arrive, you need to spread your arms, try to grab the ice, and, if possible, give your body a horizontal position. Try your best to stay on the surface.
Poems about safety rules on ice Winter! Hurry up and skate! What glorious days! But you can’t go out on the ice, While it is fragile, friends, When there are cracks on it, When suddenly it gets warmer during the day... If you fail, trouble will come: Cold water in winter...
On frozen lakes the ice can be fragile, and walking on it is very irresponsible! Bodies of water are dangerous: The ice may fall through, and saving you is in vain
The whole neighborhood will rush... After all, it is almost impossible to get close to the ice hole - It will be difficult to pull you out of the water, brothers...
