How to pay attention to traffic safety when walking?

1. Walk on the road and walk on the sidewalk; For roads without sidewalks, take the roadside.

2. When going out in groups, it is best to walk in an organized and orderly manner; When going out together, don't chase, fight and play with each other; Pay attention to your surroundings when you walk. Don't look around, read newspapers or do other things while you walk.

3. On the road without traffic police command, learn to avoid motor vehicles and don't argue with them.

4. In foggy days, rainy and snowy days, it is best to wear colorful clothes, so that motorists can find the target as soon as possible and take safety measures in advance. In some cities, primary school students wear small yellow hats when they go out, and they also hold "Rang" plates when they take part in group activities, in order to let motor vehicles find and avoid them in time. This practice should be advocated.

What should be paid attention to in fire prevention?

There are many measures to prevent fire. Students should first start with the little things in daily life:

Don't play with fire. Some students are curious about fire and often play games with fire behind their parents and teachers. This is very dangerous. When playing with fire, once the fire spreads or leaves unfinished fire, it is easy to cause fire.

2. Don't smoke. Smoking is harmful to health and easy to cause fire. We must abide by the student code and school rules and regulations and resolutely put an end to smoking.

3. Take care of fire control facilities. In order to prevent fire and fire accidents, fire hydrants, fire extinguishers, fire sandboxes and other fire-fighting facilities have been set up in residential buildings and public places, and safe passages for evacuation have been left in case of fire. We should consciously care for fire control facilities and ensure the smooth passage of safety.

When calling the police, it is necessary to explain to the fire department the unit or place where the fire broke out, the district (county), street, alley, house number or national address, what was on fire and how the fire was.

4. After the alarm, it is best to arrange personnel to wait for the fire truck at the nearby intersection to guide the way to the fire.

Learn to turn off the main power supply in an emergency.

How to pay attention to safety in indoor activities?

There are many seemingly small things that deserve students' attention when they are doing indoor activities at home, otherwise, they are prone to danger. This mainly includes the following aspects:

Length anti-collision device. At present, the living room space of most families is relatively small, and many household items such as furniture are placed, so don't chase and fight in the living room, do strenuous sports and games to prevent bumping and injury.

2. Anti-skid and anti-fall. The living room floor is relatively smooth, so attention should be paid to prevent slipping and injury; When you need to climb up to clean and pick up things, please ask others to protect you and pay attention to prevent you from falling.

3. prevent falling. If you live in a building, especially a high-rise building, don't lean out of the balcony or window to avoid the danger of falling.

4. Reverse extrusion. Doors and windows of the living room, doors and drawers of furniture are easy to cover your hands when opening and closing, so be careful everywhere.

5. Fire prevention. There are many flammable items in the room, such as wooden furniture, bedding curtains, books, etc., so pay attention to fire prevention. Don't play with fire casually in the room, let alone set off firecrackers in the room.

6. Prevent accidents and injuries. Sharp tools such as screwdrivers, knives and scissors, and stationery such as pushpins and pins should be properly stored after use. It should not be placed on the bed or chair at will to avoid accidental injury.

Fire prevention 1, basic requirements: primary school students are not allowed to play with fire.

First, don't bring kindling such as matches or lighters; Second, it is not allowed to ignite at will, and it is forbidden to use fire for flammable and explosive materials; Third, it is not allowed to set off firecrackers in public places and throw lit firecrackers around. At the scene of the fire, primary school students and other minors should adhere to the principle of escaping first.

2, the way to deal with the fire, there is a fire at home, don't panic, and take corresponding measures in time according to the fire: if the oil pan catches fire when cooking, quickly cover the lid tightly, so that the oil fire in the pan is extinguished due to lack of oxygen, and it cannot be put out with water. When a fire breaks out indoors, doors and windows cannot be easily opened to avoid air convection and form a large-scale fire.

When paper, wood and cloth catch fire, water can be used to put out the fire. When electrical appliances, gasoline, alcohol and cooking oil catch fire, earth, sand and mud and dry powder fire extinguishers can be used to put out the fire. If the fire is very big, you must report the fire immediately.

When you are trapped by fire, you should take different methods to escape according to different situations. If you lean down, cover your nose with a damp cloth.

3. How to call the police in case of fire? If a fire is found, the most important thing is to call the police, so as to put out the fire in time, control the fire and reduce the losses caused by the fire. The telephone number of the fire alarm is 1 19.

This figure should be kept in mind. In any part of the country, the telephone number for reporting fire to the public security fire department is the same. According to this figure, 1 1.9 is designated as the fire safety day every year.

You can't call the fire alarm at will. It is illegal to lie about the fire alarm, which disturbs public order. When there is no telephone, you should shout loudly or take other measures to attract the attention of neighbors and pedestrians, and assist in fire fighting or alarm.

4. How to get out of danger correctly in case of fire? In case of fire, correct and effective methods should be taken to save yourself and escape, so as to reduce personal injury and loss: 1) Once threatened by fire, don't panic, calmly determine your position, judge the fire according to the analysis of surrounding smoke, light and temperature, and don't take actions blindly. 2) In the bungalow, if the fire around the door is not big, you should leave the fire quickly.

On the other hand, you must choose another exit to escape (such as jumping out of the window) or take protective measures (such as soaking clothes with water, wrapping your head and upper body with warm quilts, etc.). ) before leaving the fire. 3) If you find a fire in a building, don't blindly open the doors and windows, otherwise it may lead to a fire.

4) If you are in a building, don't run around blindly, let alone jump off a building to escape, which will cause undue casualties. You can hide in the room or on the balcony.

Close the doors and windows, cut off the fire road and wait for rescue. Conditional, can continue to water the doors and windows to cool down, in order to delay the spread of the fire.

5) In a burning building, don't use the elevator to escape, but take the stairs through the fire escape. Because the elevator shaft often becomes a channel for setting off fireworks after a fire.

And the elevator may break down at any time. 6) If the fire is too fierce and you need to jump off a building to escape, you can jump off the second floor, but you should choose a soft ground. At the same time, throw the bedding upstairs to increase the cushion of the ground, and then slide down the window, so as to minimize the falling height and let the feet land first.

7) If you are sure, you can tie one end of the rope (or tear the sheets together) to the window frame and then slide down the ground along the rope. 8) When running away.

Try to take protective measures, such as covering your nose and mouth with a wet towel and wrapping your body with wet clothes. Second, traffic safety class China's "Traffic Law" stipulates that motor vehicles driving on roads in China must abide by the principle of driving on the right, and motor vehicle drivers and front seat passengers must wear seat belts.

1. How to pay attention to traffic safety when walking? When students go to school, it is the most crowded time of the day. There are many people and cars, so we must pay great attention to traffic safety. 1) Walk on the road and walk on the sidewalk; For roads without sidewalks, take the roadside.

2) When going out in groups, it is best to walk in an organized and orderly manner; When going out together, don't chase, fight and play with each other; Pay attention to your surroundings when you walk. Don't look around, read newspapers or do other things while you walk. 3) Learn to avoid motor vehicles and don't argue with them on the road where there is no traffic police command.

4) Pupils should wear yellow hats when queuing after school, and it is best to wear colorful clothes in foggy and rainy days, so that motorists can find the target as soon as possible and take safety measures in advance. 2. What should I pay attention to when crossing the road? When crossing the road, the possible risk factors will increase greatly, so pay special attention to safety.

1) When crossing the road, obey the command of the traffic police; It is necessary to obey the traffic rules and achieve "green light, red light stops". 2) When crossing the road, take the crosswalk line; In sections with overpasses and underpasses, you should consciously take overpasses and underpasses.

3) When crossing the road, go straight and don't detour; In the section where there is no crosswalk, you should look at the left first, then at the right, and you can only cross the road when you confirm that there is no motor vehicle. 4) Don't climb over the safety fence and isolation pier in the middle of the road, and don't skate on the road.

5) Don't cross the street suddenly, especially if an acquaintance or friend is on the phone across the street, or if the bus you want to take has pulled into the station, and don't act rashly to avoid accidents. 3. How to identify traffic lights? There are two kinds of traffic lights. One is the red, yellow and green traffic lights used to direct vehicles, which are set in conspicuous places at intersections and are called vehicle traffic lights. The other is the red and green signal lights used to guide pedestrians to cross the road, which are set at both ends of the crosswalk and called crosswalk lights.

China's traffic laws and regulations also stipulate that when the traffic signal light: 1) is green, vehicles and pedestrians are allowed to pass, but turning vehicles shall not hinder the passage of straight vehicles and pedestrians. 2) When the yellow light is on, vehicles and pedestrians are prohibited from passing, but vehicles that have crossed the stop line and pedestrians that have entered the crosswalk can continue to pass.

3) When the red light is on, vehicles and pedestrians are not allowed to pass. 4) When the green arrow light is on, vehicles are allowed to pass in the direction indicated by the arrow.

5) When the yellow light flashes, vehicles and pedestrians can pass under the principle of ensuring safety. 4. Bicycle riding safety knowledge China is called "the kingdom of bicycles" and has the largest number of bicycles in the world.

But the bicycle is simple in structure, easy to fall and stable.

5. Handwritten safety tips (clear pictures and clear words)

Emergency measures under various circumstances when the earthquake comes; The principle of emergency protection during earthquake; It is a good emergency protection method to avoid nearby during an earthquake and evacuate to a safe place quickly after the earthquake.

The so-called near avoidance is to make different countermeasures according to different situations. How do school personnel prevent earthquakes? In school, what is most needed in the earthquake is the calmness and decisiveness of school leaders and teachers.

In areas with medium and long-term earthquake prediction, students should be taught about earthquakes, prevention and shock absorption in combination with teaching activities. Before the earthquake, we should arrange the route and venue for students to transfer and evacuate; After the earthquake, calmly direct the students to evacuate in an orderly manner.

In a relatively solid and safe house, students who can hide under desks, beside platforms and in teaching buildings can go to small rooms supported by pipes, and students are not allowed to run around or jump off buildings. How to prevent electric shock when walking in the street during an earthquake? When the earthquake occurred, the glass fragments of high-rise buildings and the concrete fragments outside the buildings, as well as advertising signs, tinplates, neon red light frames, etc. , may fall and hurt people. So when walking in the street, you'd better put your bag or soft things on your head, and you can also put your hands on your head when you are free. Try to be prepared for self-defense. To be calm, leave the telephone poles and fences quickly and run to a relatively open place to hide.

How do workshop workers prevent earthquakes? Workshop workers can hide under cars, machine tools and tall equipment, and don't panic and run around. Workers in special posts should first close the valves of flammable, explosive and toxic gases, reduce the temperature and pressure of high-temperature and high-pressure pipelines in time, and close the operation equipment. Most people can leave the work site, and a few people can stay at the site to monitor the danger at any time under the premise of safety protection, deal with possible accidents in time and prevent secondary disasters.

How to deal with an emergency when an earthquake occurs? (1) The driver should slow down as soon as possible and brake gradually; (2) Passengers (especially on the train) should firmly grasp the handle, post or seat with their hands, and pay attention to prevent luggage from falling from the luggage rack and hurting people. People facing the driving direction should put their arms on the seat cushion in front, protect their faces, lean toward the passage, and protect their heads with their hands; People with their backs to the direction of driving should protect the back of their heads with their hands, raise their knees to protect their abdomen, tighten their bodies and take a defensive posture. How to deal with the earthquake in buildings? Once an earthquake happens, keep a clear head, judge the vibration in time, and never jump off a building in a panic.

Secondly, you can hide under solid furniture, or in a corner, or you can move to a kitchen, toilet and small room with many load-bearing walls for temporary shelter. Because these places have strong binding force, especially the pipeline has good supporting force and large seismic coefficient after treatment.

In a word, according to the building layout and indoor conditions, we can evaluate the situation and find safe spaces and passages to avoid and reduce casualties. How to deal with the store earthquake? The department store kept calm when it was hit by an earthquake.

Due to the panic of people and the falling of goods, the refuge passage may be blocked. At this time, you should hide near big pillars and big commodities (avoid commodity display cabinets), or hide in an unobstructed passage, and then bend down and wait for the earthquake to subside.

In the upstairs position, in principle, it is best to transfer to the ground floor. However, stairs are often the weak parts of buildings in earthquake resistance. Therefore, we must seize the opportunity to escape.

Attendants should organize the masses to avoid nearby and evacuate safely after the earthquake. If you are buried under the ruins after the earthquake, it is dark around and there is only a very narrow space. Don't panic, be calm, build up confidence in survival, and believe that someone will come to save you and do everything possible to protect yourself.

After an earthquake, there are often many aftershocks, and the situation may continue to deteriorate. In order to avoid new injuries, we should try our best to improve our environment. At this time, if you carry an emergency kit with you, it will play a great role in getting out of danger.

In this extremely unfavorable environment, first of all, we should protect the smooth breathing, remove the debris from the head and chest, and cover your mouth and nose with wet clothes when you smell gas and toxic gases; Avoid weak collapsed objects and other falling objects above the body; Expand the stable living space and support the ruins with bricks and sticks to prevent the environment from further deterioration after aftershocks. Try to get out of danger.

If you can't find a way out of danger, save your strength as much as possible, and beat something that can make a sound with a stone to send out a distress signal. Don't cry, don't be impatient, don't act blindly, it will consume a lot of energy and physical strength. Try to control your emotions or close your eyes and wait for rescuers to arrive. If you are injured, try to dress it to avoid excessive bleeding.

Sustain life. If you have been buried under the rubble for a long time, rescuers have not arrived, or you have not heard the distress signal, you must find ways to maintain your life. Water and food in the earthquake-proof bag must be stored, and ways should be found to find food and drinking water. Your urine can also quench your thirst if necessary.

After the earthquake, it is impossible for the external disaster relief team to rush to the disaster relief site immediately. In this case, in order to let more people buried under the rubble get precious lives, people in disaster areas actively participate in mutual rescue, which is the most timely and effective way to reduce casualties, and also embodies the lofty virtue of "saving people from danger". Timely rescue time, the greater the hope of being rescued.

According to relevant data, the survival rate of the rescued personnel within 20 minutes after the earthquake is over 98%, and the survival rate of the rescued personnel within 1 hour after the earthquake is reduced to 63%. Among those who could not be rescued within two hours after the earthquake, the number of people who died of suffocation accounted for 58% of the deaths. They were not killed by the collapse of buildings in the earthquake, but died of ventricular arrest. If they can be rescued in time, they can completely get life.

Hundreds of thousands of people were buried in the ruins in Tangshan earthquake, and most of them were reborn through self-help and mutual help. The mutual aid action of the people in the disaster area has played an irreplaceable role in the whole earthquake relief.

The time to save people after the earthquake should be fast, and the principle of fast time, accurate target, proper method and growing mutual rescue team should be strived for. The specific approach is: first save the neighborhood, whether it is family, neighbors or strangers, don't go far; Save those who are saved first, so as to quickly expand the mutual rescue team; Save young adults and medical staff first, so that they can give full play to their role in disaster relief; Save "life" first, and then save "people"

6. Safety knowledge handwritten newspaper

Handwritten newspaper? Guess it's from school? In fact, just draw illustrations, frames and the like, and write some safety knowledge directly.

The following points are for reference: (1) Common fire hazards 1. Classroom fire hazard (1) The door is not opened or only one door is opened; (2) Use high-power lighting or electric heating appliances to keep warm near flammable materials; (three) the use of electronic teaching AIDS in violation of operating rules; (4) line aging or overload; (five) failing to store flammable items in accordance with safety regulations; (6) Smoking and littering cigarette butts in the classroom. 2. Laboratory fire hazard (1) The flammable and explosive articles in the laboratory are improperly preserved or broken and scattered; (2) violation of operating procedures during the experiment; (3) Lack of special guidance during the experiment; (4) The experimental project lacks fire prevention measures; (5) mixing storage reagents.

3. Library fire hazard (1) short circuit of wires and electrical equipment; (2) accidental lighting such as matches and lighters; (3) Smoking and littering cigarette butts; (4) The evacuation passage is not smooth. 4. The dormitory fire hazard (1) uses inferior electrical appliances: (2) illegally uses high-power electrical equipment, which makes the line overload; (3) connecting wires privately; (4) smoking in bed: (5) lighting candles and reading in mosquito nets; (six) unauthorized use of kerosene stoves, liquefied gas stoves, alcohol stoves and other appliances that may cause fire; (7) Burning sundries: (8) The desk lamp is close to pillows and bedding; (9) The mobile phone charger charges on the bed.

5. Auditorium and lecture hall fire hazard (1) wire aging: (2) littering cigarette butts; (3) High-power lighting is close to curtains or flammable decorations; (four) the illegal use of open flames; (5) The emergency doors and evacuation passages are blocked; (6) The number of people in the venue seriously exceeds the rated number. (2) Fire protection 1. Fire Prevention in Student Dormitories The fire safety of student dormitories should be done in ten ways (1). (2) Don't smoke and throw cigarette butts in bed. (3) Don't occupy or block evacuation passages. (4) Don't burn sundries in the building. (5) Don't bring inflammable and explosive articles into the building. (6) Don't use electric heating equipment such as "quick heating". (7) Don't use open flames such as alcohol stoves.

2. Fire prevention of common electrical appliances (1) Causes of fire caused by hair dryer and fire prevention safety measures (1) 1. During the use of hair dryer, due to other things (such as answering the phone, someone knocking at the door, etc. ) I put the hair dryer on the wooden table and completely forgot the purpose of the hair dryer. As a result, it was put on hold for a long time, so the hair dryer shell was ignited at high temperature. Second, when using the hair dryer, if you encounter power failure, you should handle other things or go out without cutting off the power supply. After the power supply is restored, the heating wire of the hair dryer heats up for a long time, and the temperature rises, causing a fire.

2) Fire safety measures for hair dryers: First, power sockets and wires should meet fire safety requirements, and the connections should be tight and firm. 2. Beware of knocking, bumping and disassembling the hair dryer, so as not to damage the heating elements and insulation devices, causing leakage or even short circuit and fire.

Third, people can't leave when using the hair dryer, and can't put it on flammable materials such as benches, sofas and mattresses at will. Fourth, be sure to cut off the power supply in time after use.

(2) Causes of fire caused by incandescent lamps and fire safety measures 1) Causes of fire caused by incandescent lamps: First, the surface temperature of incandescent bulbs is very high, and combustible materials in contact or close to them will burn. Under general heat dissipation conditions, the surface temperature of incandescent bulbs increases with the increase of their power.

For example, for incandescent lamps with power of 40 watts, 100 watts and 200 watts, the bulb surface temperature can reach 50-60 degrees Celsius, 170-200 degrees Celsius and 160-300 degrees Celsius respectively. Such as wood, paper, cotton cloth, firewood, etc. , are low ignition point, if close to the light bulb is energized, it is easy to bake and catch fire.

The test shows that the 200-watt incandescent lamp clings to the wooden box and can bake the wooden box in less than 1 hour. If you hold the cotton-padded coat tightly, it will catch fire in only 5 minutes. The greater the power of the bulb, the longer the turn-on time, the higher the surface temperature of the bulb, the lower the ignition point of combustible materials, and the closer the distance between them, the easier it is to cause combustion.

Second, because the power supply voltage is too high, the bulb power is too large, the load capacity of the conductor is small, and the insulation is aging, which leads to overheating, short circuit and fire. Thirdly, because the power supply voltage is too high and the filament calorific value is too high, the inert gas inside the bulb expands violently, or the bulb with high power and high surface temperature is quenched and heated, splashed with water and vibrated. , causing the bulb to explode, and the high-temperature glass sheet and high-temperature filament splashed on the combustible, causing a fire.

Fourth, because the contact part of the lamp holder is in poor contact, it leads to fever and fire; When the glass shell of the lamp holder is loose, the lamp holder is twisted, which leads to short circuit and fire. 2) Fire safety measures for incandescent lamps: First, the bulbs should be set in safe and proper places, and keep a certain fire distance from combustible materials.

Where collision may occur, the light bulb should have a metal protective net or a glass cover. Second, it is forbidden to cover lamps with paper, cloth or other combustible materials, and it is forbidden to use light bulbs to keep warm and bake clothes under quilts.

Third, light bulbs should not be attached to wooden furniture, doors, frames or cardboard, nor embedded in the ceiling or ceiling. When moving the desk lamp, the light bulb should keep a certain distance from flammable materials such as curtain cloth and mosquito net.

Fourth, the power supply voltage of incandescent lamp can't exceed its rated voltage. Don't touch the working light bulb with wet hands or wet cloth to prevent the light bulb from exploding.

If the connection between the lamp holder and the glass bulb is loose, don't twist the bulb hard. If you use a light bulb above 150 watt, don't use a bakelite lamp holder to avoid heating and fire.

Fifth, the wires used for incandescent lamps should have excellent insulation performance. The conductor shall not be close to the bulb to prevent the insulation layer of the conductor from aging, melting and burning due to long-term baking.

Safety devices should be installed on the lines to protect them. The switch shall not be installed on the ground wire.

Sixth, when using incandescent lamps, especially high-power incandescent lamps, the continuous power-on time should not be too long, and the "ever-burning lamp" should not be lit. Remember to turn off the lights when you go out to class.

(3) Causes of fire caused by fluorescent lamps and fire safety measures 1) Causes of fire caused by fluorescent lamp ballasts: First, the quality of ballasts is poor. Some ballasts have not been strictly inspected or wound by themselves before leaving the factory, and the poor quality is due to shoddy construction, such as the number of turns of the coil.
