6. Little is known about safety

Pupils' traffic safety knowledge When the crosswalk signal light is green, pedestrians are allowed to cross the crosswalk; When the green light flashes, pedestrians are not allowed to enter the crosswalk, and those who have entered the crosswalk can continue to pass; When the red light is on, pedestrians are not allowed to enter the crosswalk.

You shoot one, I shoot one, traffic safety comes first, you shoot two, I shoot two, the red, green and yellow lights should be seen clearly, you shoot three, I shoot three, the red light is safe, you shoot four, I shoot four, the vehicle drives to the right, you shoot five, I shoot five, pay attention to the big and small corners, you shoot six, I shoot six, don't ride a bicycle to carry people. L obey the traffic police's command and achieve "green light, red light stops". 2. Take the crosswalk line; In sections with overpasses and underpasses, you should consciously take overpasses and underpasses.

3. Go straight, 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 cross the safety fence and isolation pier in the middle of the road.

Don't cross the street suddenly, especially if an acquaintance or friend is on the phone across the street, or the bus to take has arrived, and don't act rashly to avoid accidents. What are the most dangerous situations when walking? (1) It's dangerous to cross the road.

(2) Walking sideways in groups of three or five on non-sidewalks is the most prone to traffic accidents. (3) After the rush hour, there are fewer cars on the road, because there are fewer cars and fewer people on the road.

Paralysis plus paralysis equals danger. (4) Walk with one heart and two minds, read while walking, or think while walking, or chat while walking, and play while walking ... In this way, the car may not hit you, but you will hit the car yourself, so it is also very dangerous.

Pay attention to 1 when riding a motor vehicle. You have to line up and get on the bus in order, so it's not crowded. When getting on and off the bus, wait for the bus to stop, get off first and get on, and don't fight for it.

Don't stick your head and hands out of the window, and don't throw things out of the window. 4. Sit firmly and hold well. When there is no seat, your feet are naturally separated, stand sideways, and hold the handrail with both hands to avoid falling and being injured when the vehicle brakes suddenly.

You should fasten your seat belt in the front row when you take the bus. 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.

However, due to its simple structure, the bicycle falls down when touched, and its stability is poor, so it is a weak means of transportation. In traffic accidents, the number of people injured by non-motor vehicles (mainly bicycles) ranks first, and the number of casualties ranks second.

In our country, children 12 years old or older can start cycling on the road, and they should obey the traffic rules and ride in the slow lane. When the signal light is green, pedestrians are allowed to pass; When the yellow light is on, pedestrians are not allowed to pass, but pedestrians who have entered the sidewalk can continue to pass; When the red light is on, pedestrians are not allowed to pass; When the yellow light flashes, pedestrians must pass under the principle of ensuring safety.

The regulations that pedestrians must abide by pedestrians must walk on the sidewalk, and if there is no sidewalk, walk on the right; Crossing the road requires a crosswalk; When crossing a crosswalk controlled by traffic signals, you must abide by the provisions of the signals; When passing the sidewalk without traffic signal control, look around, pay attention to the traffic, and don't chase or run; If there is no crosswalk, you must go straight through, and vehicles are not allowed to cross suddenly when approaching; Anyone who takes the overpass or underground passage must take the overpass or underground passage; It is not allowed to climb guardrails and fences along and in the middle of roads, and it is not allowed to push, chase, forcibly stop or throw vehicles on roads. What safety precautions should I pay attention to when riding a bicycle? When going out by bike, the unsafe factors are more than walking. The following safety precautions are required: 1. Always check your bike to keep it in good condition.

Whether the brakes and bells are sensitive and normal is particularly important. 2. Bikes should be the right size, and don't ride children's toy cars on the streets.

Don't ride a cart alone. 3. Don't learn to ride a bike on the road; Children under twelve should not ride bicycles in the street.

4. Riding a bicycle should be on the right side of the non-motor vehicle lane and not retrograde; When turning, don't make a sharp turn, slow down in advance, see the surrounding situation clearly, and then turn with a clear gesture. 5. After crossing the road, slow down and pay attention to pedestrians and vehicles; Don't run the red light, stop the red light and wait until the green light comes on.

6. When riding a bicycle, don't spread your hands, don't ride with many people, don't climb each other, and don't chase each other. 7. Don't climb a motor vehicle when riding a bike, don't carry overweight things, don't take people by bike, and don't wear headphones to listen to the radio when riding a bike.

The song of elementary school students' safety knowledge (1) When you meet a gangster at 1 10, you should remember your phone number clearly and be clever in dealing with it, and the gangster will be caught soon. It is not safe to swim in private, so it is necessary to prevent dizziness and spasm. If you don't drink enough water from one river, you will go to the grave when you are young. Be careful when connecting hot water, the pot will be scalded by inverted buckle, and if it is wrong, it will cost money to be sad and cure the skin asymmetry; When the river rises, it is better to be brave than to be brave. It is only safe to walk around, and it will be fine after the rain. Don't tease the dog when crossing the yard, ask adults to drive the dog away, and don't be clever. It's dangerous to be bitten by a dog. Remember not to drink raw water when you walk long distances in hot weather.

7. Safety tips

Common knowledge of residents' safety precautions in spring How to prevent gas fuel used by families with gas poisoning, such as gas, liquefied petroleum gas, biogas, etc. , are toxic gases, all contain substances harmful to human body such as carbon monoxide.

Once the human body inhales high concentrations of these gases, it will faint, and if it is not rescued in time, it will cause death. The key to prevent gas poisoning is to put an end to the leakage of these gas fuels used by families.

It should be emphasized that when using gas fuel, the environment should be well ventilated. In this way, in the case of a small amount of gas fuel leakage, there is still enough oxygen for people to breathe, so as not to cause serious poisoning accidents.

Families who use coal stoves in rural areas should also prevent coal stoves from being poisoned by staying overnight in the bedroom. If the coal stove is placed in the kitchen or living room, don't close the doors and windows when sleeping. It is best to put the coal stove outdoors or put it out at night to eliminate hidden dangers.

Especially in winter, don't sleep next to the coal stove to keep warm at night. Otherwise, it will be too late to lead to tragedy.

How to rescue gas poisoning If someone is found to be poisoned by gas, don't press any electrical switch, so as not to cause an explosion by sparks. You should first open the window to ventilate the room, then quickly move the poisoned person to an outdoor ventilated place, unbutton his collar and let him breathe fresh air.

Be careful not to let him catch cold, otherwise, his temperature may drop and his heart will stop beating. If the poisoned person can drink water, he can feed hot sugar tea and keep warm. He can't even cover his head with a cold towel, let alone pour cold water on it.

When the poisoned person has difficulty breathing or has just stopped breathing, he should immediately give artificial respiration or chest first aid, call the medical rescue unit at the same time, or ask the neighbors to help send the patient to the hospital for treatment. Of course, while saving people, we should also find out the cause of gas leakage as soon as possible and stop it, so as to avoid others being poisoned again.

How to use hot pot safely When buying hot pot, users should pay attention to product quality to prevent them from buying unqualified and inferior products. When problems are found, do not disassemble or modify them at will, but send them to the original manufacturer and maintenance point for maintenance.

Be familiar with the usage and safety knowledge before using hot pot. If you use carbon hot pot, put a plate under the hot pot and put less water or other insulation materials, which can prevent high temperature from damaging the desktop and even causing fire.

If you use liquefied gas (gas) hot pot, you should prevent gas leakage when using it. After ignition, we should always pay attention to the combustion situation and adjust the flame to prevent the soup from boiling, fire extinguishing and gas leakage, resulting in gas poisoning or fire and explosion accidents. When not in use, cut off the power. The power cord should be connected to the pot first and then to the power supply (and vice versa). Don't let the food spill. If it overflows, cut off the power first and then wipe it clean. Cut off the power supply after using the hot pot, then clean and dry the pot and store it in a dry and ventilated place.

After the electric chafing dish and gas chafing dish are used up, the power supply or gas source must be cut off, and charcoal ash should be used for safe treatment of charcoal chafing dish. The remaining alcohol in the alcohol hot pot should be poured into a container and placed in a safe place to prevent children from playing and causing fires.

Prevent electric blankets from causing fires. When the cold current comes, the elderly and infirm like to use electric blankets. However, if there is no constant temperature safety device, it is easy to cause fire accidents. In addition, the electric blanket will break when rubbed for a long time, which will also cause fire.

To prevent fire caused by electric blanket, we should first pay attention to insulation and prevent short circuit. If the electric blanket is damaged, do not disassemble and repair it at will. Ask an electrician to check and repair it.

In order to prevent you from forgetting to turn off the power for a while, you can use a three-way plug, one end of which is plugged with an electric light and the other end is connected with an electric blanket. In this way, when the light is turned on at night, the electric blanket will be electrified and heated up, and the electric blanket will also be powered off after sleeping and turning off the lights. It is best for children to sleep without an electric blanket to prevent electric shock when wetting the bed.

Electric blankets should try to avoid folding and getting wet. When the electric blanket that has not been used for a long time is reused, it is necessary to carefully check whether there is any leakage.

Once the electric blanket catches fire, cut off the power first, and then try to put out the fire. □ Yan reprinted = =.
