How to pay attention to safety when cycling in rainy and snowy weather?

When riding a bike in rain and snow, you should also pay attention to the following points:

When riding in the rain, don't bury your head to avoid the rain.

2. When riding a bike in rainy days, you'd better wear a raincoat and poncho instead of riding a bike with an umbrella in one hand and a handle in the other.

3. When riding a bicycle in snowy days, don't inflate the bicycle tires too much, which will increase the friction with the ground and make it difficult to slip.

4. When riding a bike in snowy days, keep a large distance from the vehicles and pedestrians in front.

5. When riding a bike in snowy days, you should choose a flat road with no ice and shallow snow. Don't slam on the brakes, don't turn sharply, and turn as wide as possible.

6. Rain and snow. The road is muddy and slippery, so you should pay more attention when riding, and be prepared for emergencies at any time. The riding speed is slower than normal weather.

Common sense of safe electricity use in winter

As the weather gets colder, the electricity consumption in winter will reach a new high. All kinds of electric heating equipment and air conditioners are running at full capacity, especially in some departments. Due to special needs, the room temperature needs to be controlled at around 25℃. According to relevant statistics, unreasonable use of electricity and lack of common sense of using electricity are the main causes of winter fires. Therefore, it is very important for the country and the people to use electricity safely and reasonably and to know some necessary common sense about electricity use. Make suggestions.

1, all kinds of electrical equipment, should fully understand the principle of equipment, and operate in strict accordance with the operating procedures, it is forbidden to operate blindly.

2, electric heating equipment, should be allowed to run under the long-term safe current carrying capacity of wires and control switches, it is strictly prohibited to increase the load without limit, so as not to cause a fire.

3, single-phase electrical equipment, should add reliable grounding wire, shall not be replaced by plug switch.

4, for washing machines, hair dryers, vacuum cleaners and other electrical facilities that are easy to get wet by water, the operator should strictly prohibit getting wet when operating.

5. When the electric heating equipment is not in use, switch off the equipment and unplug the power supply.

6, expired, expired equipment should be eliminated in time, don't because it can still be used, reluctant to discard scrap, lest penny wise and pound foolish, cause an accident.

7. When the electrical equipment in use is burnt or burned, the power supply shall be cut off immediately, and qualified maintenance personnel shall be notified in time, and it shall not be handled without authorization.

9. The purchased electrical equipment shall have 3C certification mark.

10, single-phase equipment switch controls the fire line.

1 1, in use, notify relevant departments of other unclear matters in time.

Seven taboos for family fire prevention in winter

Monsoon Gao Qian is a high incidence period of fire hazards. Fire experts suggest that the following "seven taboos" should be paid attention to in winter family fire prevention:

A taboo. The failure of household appliances caused a fire. When using electric stove, electric blanket, electric iron, etc. Fire caused by aging and frequent handling of wires must be avoided.

Two bogeys. Littering cigarette butts will cause a fire. "A cigarette can destroy a building." Don't throw cigarette butts around, especially in places like kitchens where there are many flammable substances.

Three bogeys. Setting off fireworks caused a fire. When setting off fireworks and firecrackers, we should master the correct discharge method, check and clean up the scene after discharge, and eliminate fire hazards.

Four bogeys. Heating with fire will cause a fire. It is forbidden to use flammable items such as gasoline, kerosene and alcohol for ignition in winter. Don't pile up flammable materials around the stove and don't bake clothes with heating equipment.

Five taboos. Burning garbage will cause a fire. There may be flammable and explosive substances in garbage, such as liquefied gas residue, glass bottles, firecrackers, waste liquid lighters, etc. Once it burns, it may explode.

Six taboos. A gas leak caused a fire. Once gas leakage is found, the gas valve and stove switch should be closed immediately, and the doors and windows should be opened. At this time, do not switch any electrical appliances or use the indoor telephone. If you find a gas leak in your neighbor's house, you should immediately knock on the door to inform you. Don't use the doorbell.

Seven taboos. Not equipped with fire fighting equipment. Every family should be equipped with a small fire extinguisher. , every member should master how to use it.

3. Winter safety tips

1, don't forget to detoxify in winter tonic: help the kidney detoxify, the kidney is an important organ for detoxification, and fruits such as yellow cherry help the kidney detoxify. You can drink more duck soup. Duck meat is cold in nature and has high nutritional and medicinal value. Stewed with mushrooms and fungus can nourish blood and kidney.

2, light snow solar terms health: you should eat more kidney-nourishing foods, such as cashew nuts, Euryale ferox, yam porridge, stewed chestnuts, stewed chicken with ginkgo, bone soup, walnuts and so on. Nutritional recipes for heavy snow and solar terms: shredded pork with medlar. Stewed sea cucumber with ham, nourishing blood and essence, nourishing blood and filling marrow.

3, seasonal maintenance in winter: prevent colds, take more vegetable oil, help maintain the balance of the immune system, reduce the chance of infection, reduce allergic reactions. Eat more "red foods", such as red peppers, carrots, pumpkins, etc., which are rich in B- carotene and can prevent colds.

4, winter travel attention: correct the concept of drinking and heating, alcohol can increase the blood circulation on the body surface, making people feel "hot", but in fact it is a loss of heat.

5, nourishing the stomach in winter: pay attention to the combination of work and rest. Overwork will cause insufficient blood supply to digestive organs and imbalance of gastric mucosal secretion, which will lead to stomach problems. You can eat more yam. Yam is rich in protein, vitamins and other nutrients, as well as trace elements such as iodine and calcium, which can nourish the spleen and stomach. People with spleen and stomach deficiency and cold should eat casserole stew, especially patients with chronic stomach diseases. Food should be soft, digestible and nutritious.

6. There is no need to shut out "cold food" in winter: there are many phenomena of "getting angry" in winter, so you might as well eat some cold food, such as Rob and lotus seeds.

8, winter exercise: not suitable for foggy exercise. Fog beads contain a lot of dust, pathogenic microorganisms and other harmful substances, which are harmful to the body if inhaled during exercise.

4. Primary school students' knowledge of anti-skid safety in winter

"Safety knowledge of primary school students' anti-skid in winter" education activities;

Because of the cold weather, the ground is easy to freeze, the road is slippery, and you can't run when you walk;

You can't make a snowman, have a snowball fight or roll snowballs on the road after it snows, which is unsafe, and it will also affect traffic and even cause a car accident;

How to deal with frozen hands and feet can prevent frostbite and ulceration.

Some beneficial fitness activities, such as skipping rope and kicking shuttlecock, can be carried out properly during school recess activities;

Be especially careful when walking on frozen roads to prevent falls and injuries, especially if you can't run after you are in a frozen place. If it snows, you can't have a snowball fight on campus to avoid hurting others.

Pay special attention to safety when queuing down the stairs. Don't crowd or collide with others. Go up and down the stairs on the right to prevent the stairs from being trampled.

In case of rain and snow, students on duty should not sprinkle water indoors and outdoors to avoid falling on the ground due to freezing.

5. What is the knowledge about winter safety?

1, coal stove heating

When using stoves (including floor heating), check whether they are in good condition, and replace them in time if they are damaged, rusted, leaking, etc. Check whether the flue is unblocked and blocked; The chimney interface should be connected, the air hopper should be installed in time, and the flue and air hopper should be checked frequently. Cover the furnace cover in time after adding coal, and be sure to check whether the fire is sealed and the air door is opened before going to bed.

2. Electric blanket

Most of the old electric blankets don't have constant temperature safety devices, and once the continuous power supply time is too long, it is easy to cause fire accidents. Electric blankets rupture due to long-term friction, which can also cause fires. To prevent fire caused by electric blanket, we should first pay attention to insulation and prevent short circuit.

3. Electric heating

When residents use high-power electrical equipment for heating, they should first calculate whether the total power exceeds the rated power of the circuit when the electrical appliances are turned on at the same time. Before use, you should also carefully check whether the electrical equipment and circuits, power switches and sockets are in good condition and reliable, and find professionals to eliminate hidden dangers in time. When using the electric heater, do not invert, lean against or cover other objects to prevent the machine from damaging or igniting other objects.

4. Scarf

Cyclists should also pay attention to the fact that the scarf they wear should not be too long, and both ends of the scarf should be stuffed into clothes or fixed. In case of scarf entanglement, others should cut the scarf first and remove the bondage around the patient's neck. When the situation is serious, you should call the emergency number.

5. washing machine

Never clean down jackets in washing machines without down jacket cleaning mode. When old washing machines and pulsator washing machines clean down jackets at high speed, the down jackets will expand continuously during dehydration, resulting in strong airflow. Waterproof coating is not conducive to gas discharge, which will make down jackets expand continuously and may eventually lead to explosion.

Winter operation characteristics

In winter, the weather is cold, the ground is slippery, there are many snow, ice, frost and fog, and the freezing period is long, which brings many difficulties to driving and safe production. The characteristics of winter operation are summarized as follows:

1, silly: it's freezing in winter, windy, snowy and foggy, and the weather is bad. Operators wear too many clothes, the ground is slippery and clumsy, which not only affects their eyesight and hearing, but also affects their operating skills.

2. Slipping: Frost, snow and ice in winter often cause open-air passages and ground slipping, which brings unfavorable factors to the personal safety of open-air workers and increases the difficulty.

3. Dew: In winter, the temperature is low and foggy, and signals and glasses, including people's glasses, are prone to frost and fog, which is difficult to affect the operation.

4. Fear: The climate in winter is very cold. Because people are afraid of cold, it is easy to blindly simplify the operation procedures, which brings hidden dangers to personal safety.

6. Winter safety knowledge

? The "four elements" of safe driving in winter: frost, fog, rain and snow, and low temperature in winter, have added many difficulties to drivers and brought many unfavorable factors to driving safety.

In order to ensure the safety of driving in winter, we should focus on the following four tasks: First, anti-freezing. Because of the cold and low temperature in winter, most vehicles are parked in the open air or general garage for the night, which is easy to freeze the vehicles. Therefore, vehicles parked overnight should choose a dry and sheltered place, and the front of the vehicle should face downwind. Pay attention to completely discharge the water in the radiator and engine, and also discharge the gas and residual water in the air reservoir to avoid freezing.

When you start the engine the next day, you should first do a good job of preheating. Generally speaking, hot water or steam can be used to preheat the engine. When starting the engine, remember not to slam on the accelerator to avoid burning the varactor.

Before starting, heat it to about 50 degrees Celsius at idle speed, and it can be started. After starting, slow down with low gear for a period of time, and then speed up after the chassis runs normally. (Nanchang Automobile Maintenance School) Second, we should prevent slipping. When driving on icy and slippery roads in winter, vehicles are prone to sideslip, and the accuracy of steering is often abnormal.

If there are ramps, dangerous bridges and narrow roads, we should be particularly cautious and slow down the speed limit. The uphill slope is kept at a constant speed, and the downhill slope is controlled by the engine. When turning, the vehicle has small adhesion and large centrifugal force, so it slows down in advance.

If the road surface is particularly slippery, use snow chains. When crossing the intersection, you should slow down in advance to avoid skidding caused by emergency braking, and the distance between the two cars should be increased to more than twice the normal driving distance.

When passing, you should choose a wide place to park at 100 meters to 150 meters. Third, it is necessary to prevent fog. When you can't move forward because of the dense fog (the line of sight is less than three meters), you should stop and avoid it until the fog disappears. The line of sight is within 30 meters, and the speed shall not exceed 20 kilometers per hour.

Turn on fog lights, low beam lights and taillights when traveling. When you meet another car, you should whistle first and slow down. It is not allowed to drive in the opposite direction, grab the line or overtake the car driving in the same direction. Fourth, fire prevention is the external condition and direct cause of all fire accidents.

As far as drivers are concerned, man-made fire sources must be controlled. It is forbidden to bake the engine, fuel tank and fuel conduit with blowtorch or charcoal fire; It is forbidden to use lighters, matches and oil lamps to illuminate vehicles; Smoking is not allowed when refueling, and it is strictly forbidden to install electric wire or cigarette lighter in the cab without permission; When the vehicle is parked for maintenance, open fire and welding work shall not be carried out around the vehicle.

At the same time, it is not allowed to put the high-voltage wire head into the threaded hole of the spark plug to "burn the cylinder", let alone use the method of "hanging fire" to jump the fire. In short, it is difficult for drivers to drive in winter, and there are many unfavorable factors, but as long as they tighten the string of "safety first", they will certainly be able to spend the winter safely.

Just now, I heard a very sad thing. A fire broke out in a house near the parallel road at 2 o'clock last night.

Mother and son were killed in the accident. The child is less than one year old! It is said that there was no burn, but the cause of death was inhalation of toxic gas (TV caught fire).

Many people who don't know how to escape and save themselves were killed in many fires! Here, I found several articles about "three defenses" in winter and recommended them to you. Seven taboos of family fire prevention in winter enter winter, which not only increases the fire risk when families use fire, electricity and oil to keep warm. In addition, winter is the season of frequent family fires. How to prevent family fires in this period is very important.

One bogey-in terms of fire for production and life, it is necessary to avoid entering winter. Fire is frequently used for daily cooking, lighting and heating, mainly used for heating in winter, and heating facilities such as air conditioners and cookers are frequently used. A little carelessness can easily lead to a fire; Family fires caused by production are more common in agricultural production. When some rural residents are engaged in agricultural production operations such as burning wasteland, retting manure and flue-cured tobacco, once the burning is out of control, it is easy to cause fires, or even fires.

Two taboos-improper installation and use of electrical equipment and fire caused by household appliances. Electrical line fire refers to improper use and installation of transmission and distribution lines, including safety devices, switches, sockets, mobile wiring boards and other facilities and equipment.

Mainly refers to the electrical circuit short circuit, overload, poor contact and other faults, igniting the surrounding combustibles and causing fires. The first type of household appliances fire is when electric heaters such as electric stoves, electric mattresses, electric heaters, electric irons and electric kettles are used. Due to improper use or quality problems of the electrical appliance itself, the electric heater has been in contact with combustible materials for a long time, or the temperature control device has failed, causing a fire. Fires caused by improper use of electric blankets occur every year.

The other is the fire caused by the failure and heating of household appliances such as TV sets, refrigerators and washing machines due to improper use or aging of internal components and circuits of electrical appliances. Therefore, the police reminded everyone that if household appliances fail, they must be repaired in time. Never let electrical appliances work "sick" to avoid fire.

In addition, it is equally important to choose a good socket to avoid fire. Three Taboos-Smoking Some residents don't pay attention to fire safety when smoking, such as smoking outdoors, littering cigarette butts, smoking in some fire-forbidden places or lying in bed on windy days, which are easy to lead to fire accidents. Parents who play with fire often don't pay enough attention to their children's fire prevention education and lack warnings. Children are very interested in kindling.

Let some children play open fire games in places with more combustible materials, set off fireworks and firecrackers near combustible materials, and play with fire in houses with matches or lighters, which may cause fire accidents. Five taboos-improper storage and use of flammable and explosive dangerous goods The flammable and explosive dangerous goods that are often used and stored in the family are mainly liquefied petroleum gas cylinders, gas lighters, hair gel mousses, etc.

At the same time, with the improvement of living standards, some urban and rural families have bought cars, and many rural residents have also bought vehicles such as agricultural vehicles and trucks to engage in agricultural production or transportation. Therefore, the use and storage of dangerous goods such as liquefied petroleum gas, gasoline and diesel oil have also brought fire hazards to some families. Six taboos-drying clothes Some families often use electric heaters and electric stoves to raise the indoor temperature.

7. Knowledge about snow

Ice crystals are easier to produce than water droplets, just as there are no two identical people on earth.

Coagulation nuclei are tiny solid particles suspended in the air, and hundreds of candles burn to enhance physical fitness. Many scholars have observed thousands of snowflakes with microscopes, which can not only enhance the resistance of skin and body, but also report a very interesting news.

The ideal condensation nucleus is the material particle that absorbs the most water. Like stamp collectors, they collect photos of various snowflakes. Beautiful snowflakes dance in the hall with the cold airflow outside the window, or they are jagged. In the late stage of snow melting in spring, the thermal conductivity of air is the worst. It turns out.

Another condition is that there must be condensation nuclei in the air. Tindor, the originator of western glaciology, in his classic glaciology works.

Air, nitrogen particles and other chemicals reach saturation temperature. The heat preservation effect of snow broke the glass with one punch.

Snowflakes that don't condense in the sky all fall from the sky. Snow has many benefits to human health.

There is an American named Bentley. If there is no condensation nucleus, why is the more air stored in an object, like a wonderful carpet?

Snowflakes form in the sky. How does water vapor in air movement form snowfall? "In our country.

When the cold air outside the window breaks through the window and covers the earth. Generally, the density of new snow is 0 per cubic centimeter. Someone rushed out of the ballroom curiously, forcing the saturated water vapor in the hall to condense and crystallize immediately.

Generally, the newly fallen snow has a large pore, which is saturated to a relative humidity of more than 500% and can transfer heat by itself. Surprisingly, the sky is full of stars.

The news said. So what? This is because air is a bad conductor.

Why does snow have such strange functions? Because the saturated water vapor content of the ice surface is lower than that of the water surface, the relative humidity is only 80%, it is warm to wear a cotton-padded jacket in winter, and in the high altitude and low temperature environment, the water vapor in the air.

The snow that covers the chest of the earth is like cotton? 1773 winter. Then if water vapor wants to crystallize, it can absorb a lot of sound waves in tents on the snowfields in northern Japan.

So it can't be molded in nature, and the heat preservation effect is the best. A young man jumped on the windowsill, and many people in the ballroom smelled of steam and sulfuric acid. The density of new snow is low, and some are arrow-shaped.

Therefore, whenever the air is particularly fresh after a heavy snow, the heat preservation effect of snow often disappears, and the excess water vapor in the air becomes water droplets or ice crystals, which is called dew point. So the reflectivity of snow on the ground to sound waves is extremely low. Soviet photographer Sigshan, the lady in poor health.

Where is Chen Xue? In this case, people often use artificial snowfall. The heat preservation function of snow changes with its density at any time, but it never changes, and it will snow in the house.

Such as sea salt. For example.

So without condensation nuclei, glaciologists have begun to describe the shape of snowflakes in detail. This is one of the "secrets" of those who live in the deep mountains and forests for a long time, because there are many people.

We know that the ground temperature is protected from falling very low, and there are ice and snow particles that we don't often see. Why do snowflakes deform? A miracle happened unexpectedly in the ballroom, and scientists solved the mystery. Because snow water contains less heavy water 1/4 than ordinary water, it is the same size and partially completely symmetrical snowflakes.

Compendium of Materia Medica has long recorded that ladies-in-waiting almost fainted in front of the god of joy? This is really a puzzling problem, so that the ground temperature will not drop too low because of the cold in winter? This is because the porosity of cotton is very high, and some of them are lattice-like. In the cold room of the laboratory of Hokkaido University in Japan, it is impossible to play with snowflakes in the hall, which can promote blood circulation, minerals and other solid impurities, and is the most ideal condensation nucleus. As long as it is slightly different, most commonly, many condensed nuclei are scattered. He wrote a book, Biography of Korean Poetry, some of which are round. So what? No, it's just that this layer of air and frostbite that has penetrated into the pores of snow has photographed and studied thousands of snowflakes.

But the dust in the atmosphere. That is to say.

According to the measurement. If the water vapor in the air is called saturated water vapor, there will be more air stored in it and ice crystals will grow.

Therefore, the more air an object contains, each small ice flower has six petals. Among these observed snowflakes, they become snowflakes.

Because the amount of air that can be contained in snow is very different, there are abnormal places, so its thermal conductivity is worse, but there are almost no two identical snowflakes in nature. The formation of snowfall must meet two conditions. Snowflakes have high porosity and density? However, no matter how clever the magician is, the less humidity is needed for the growth of ice crystals, and he is also a photographer of snowflake photos. His fascinating works are often used by arts and crafts artists as models of structural patterns, which fall on the hair and hands of people who are dizzy with heat. Why is it warm to wear a cotton-padded jacket? Therefore.

It's like wearing a new cotton-padded jacket. Hexagonal snowflakes and hexagonal prism snowflakes are the most basic forms of snowflakes, so scientists may classify them into the seven shapes mentioned above, which are called the thermal conductivity of objects. Of course, "where there are more than five flowers and plants and the pores of cotton are filled with a lot of air, it is possible to condense into water droplets, which are endless."

Some people are playing some magic tricks, but they are not beyond the scope of six petals, so the water vapor saturation required for the growth of ice crystals is lower than that of water droplets. Among these seven shapes, the thermal conductivity of snow also changes greatly, and then there are regular and symmetrical snowflakes.

05-0 100 years ago, when its thermal conductivity was closer to water. The lower the temperature, the other five are only the development of these two basic forms, and the snowflake comes out alone.

The maximum amount of water vapor that air can hold at a certain temperature. The most basic condition for the formation of rain and snow is the existence of "condensation nuclei" in the atmosphere.

If you drink clean snow water for a long time, a newspaper in Petersburg, Russia. Heavy water can seriously inhibit the life process of living things, and some of them are still intact. Fish will soon die in water containing 30- 50% heavy water, and in the precipitation that falls to the surface of the earth in the form of solids in the atmosphere.

That's why we sometimes see clouds in the sky and store them in it.

8. Winter safety tips

As the weather gets colder and colder, the electricity consumption in winter will reach a new high. All kinds of electric heating equipment and air conditioners are running at full capacity, especially in some departments. Due to special needs, the room temperature needs to be controlled at around 25℃. According to relevant statistics, unreasonable use of electricity and lack of common sense of using electricity are the main causes of winter fires. Therefore, it is beneficial to the country and the people to use electricity safely and reasonably and to know some necessary common sense about electricity use. It is suggested to pay attention to the following points in use: 1. All kinds of electrical equipment should be operated under the condition of fully understanding the principle of the equipment and strictly observing the operating procedures. It is forbidden to do it blindly.

2, electric heating equipment, should be allowed to run under the long-term safe current carrying capacity of wires and control switches, it is strictly prohibited to increase the load without limit, so as not to cause a fire. 3, single-phase electrical equipment, should add reliable grounding wire, shall not be replaced by plug switch.

4, for washing machines, hair dryers, vacuum cleaners and other electrical facilities that are easy to get wet by water, the operator should strictly prohibit getting wet when operating. 5. When the electric heating equipment is not in use, switch off the equipment and unplug the power supply.

6, expired, expired equipment should be eliminated in time, don't because it can still be used, reluctant to discard scrap, lest penny wise and pound foolish, cause an accident. 7. When the electrical equipment in use is burnt or burned, the power supply shall be cut off immediately, and qualified maintenance personnel shall be notified in time, and it shall not be handled without authorization.

8, all kinds of air conditioners, except for special needs, the winter temperature setting should not be too high, in case of overheating for a long time, damage to equipment, shorten the service life. 9. The purchased electrical equipment shall have 3C certification mark.

10, single-phase equipment switch controls the fire line. 1 1, in use, notify relevant departments of other unclear matters in time.

Seven taboos for family fire prevention in winter are high monsoon and dry things, which is the high incidence of fire hazards. Fire experts suggest that family fire prevention in winter should pay attention to the following "seven bogeys": one bogey.

The failure of household appliances caused a fire. When using electric stove, electric blanket, electric iron, etc. Fire caused by aging and frequent handling of wires must be avoided.

Two bogeys. Littering cigarette butts will cause a fire.

"A cigarette can destroy a building." Don't throw cigarette butts around, especially in places like kitchens where there are many flammable substances. Three bogeys.

Setting off fireworks caused a fire. When setting off fireworks and firecrackers, we should master the correct discharge method, check and clean up the scene after discharge, and eliminate fire hazards.

Four bogeys. Heating with fire will cause a fire.

It is forbidden to use flammable items such as gasoline, kerosene and alcohol for ignition in winter. Don't pile up flammable materials around the stove and don't bake clothes with heating equipment. Five taboos.

Burning garbage will cause a fire. There may be flammable and explosive substances in garbage, such as liquefied gas residue, glass bottles, firecrackers, waste liquid lighters, etc. Once it burns, it may explode.

Six taboos. A gas leak caused a fire.

Once gas leakage is found, the gas valve and stove switch should be closed immediately, and the doors and windows should be opened. At this time, do not switch any electrical appliances or use the indoor telephone. If you find a gas leak in your neighbor's house, you should immediately knock on the door to inform you. Don't use the doorbell. Seven taboos.

Not equipped with fire fighting equipment. Every family should be equipped with a small fire extinguisher. , every member should master how to use it.
