6. about the safety of knowledge
Elementary school traffic safety knowledge crosswalk signal light green light, allowing pedestrians to pass through the crosswalk; green light blinking, pedestrians are not allowed to enter the crosswalk, but has been into the crosswalk can continue to pass; red light is on, pedestrians are not allowed to enter the crosswalk.
Traffic safety clap song You clap a, I clap a, traffic safety is the first, you clap two, I clap two, red, green and yellow lights to see clearly, you clap three, I clap three, *** red light to protect the safety, you clap four, I clap four, the vehicle driving to the right, you clap five, I clap five, the size of the corner to be aware of, you clap six, I clap six, the bicycle do not carry people, you clap seven, I clap seven, do not walk and play, you clap eight, I clap eight, life is to be the first. You shoot eight, I shoot eight, life is the first, you shoot nine, I shoot nine, abide by the law is the most important, you shoot ten, I shoot ten, do a civilized little citizen Crossing the road should pay attention to what? l. Listen to the direction of the traffic police, do "green light, red light stop". 2. 2. To take the pedestrian crossing line; in the street bridge and crossing the street tunnel road, should consciously take the street bridge and underpass.
3. To take a straight line, not meandering through; in the absence of crosswalks of the road, you should look to the left, and then look to the right, to confirm that there is no motor vehicle through the road before you can cross. 4. Do not go over the center of the road safety guardrails and piers.
5. Do not suddenly cross the road, especially on the opposite side of the road there are acquaintances, friends call, or they want to take the bus **** car has come into the station, do not act hastily, so as to avoid accidents. What are the most dangerous situations when walking? (1) Crossing the road is very dangerous.
(2) Walking in groups on the sidewalk, which is most likely to cause traffic accidents. (3) After the peak of the morning and evening rush, the road vehicles are scarce, because the road less cars and people thought paralyzed.
Paralysis plus paralysis is equal to the danger. (4) walking with two minds, while walking and reading, or while walking and thinking about the problem, or while walking and chatting, while walking and playing ...... so that, may not come to the car hit you, you fall on their own to hit the car, so also very dangerous.
Ride a motor vehicle should pay attention to 1. To line up waiting for the car, according to the order of precedence on the car, not crowded. On and off the car should wait until after the car stops, first down and then up, do not scramble.
3. Do not stick your head and hands out of the window, and do not throw things out of the window. 4. To sit firmly and support, no seat, to feet naturally apart, side to stand, hands should hold the armrests, so as not to fall when the vehicle emergency braking injuries.
5. By car, in the front ride should fasten the seat belt. How to recognize the traffic signal? Traffic signals are divided into two kinds, one is used to direct the vehicle red, yellow, green signal lights, set up in the intersection of the conspicuous place, called the vehicle traffic lights; another is used to direct the pedestrian crossing the road red, green signal lights, set up at the ends of the crosswalks, called the pedestrian crossing lights.
China's traffic laws and regulations on traffic signals made provisions: 1) green light, permitting vehicles, pedestrians, but turning vehicles are not allowed to impede the straight line of vehicles and pedestrians were released to pass. 2) yellow lights, not allowed to pass. (2) When the yellow light is on, vehicles and pedestrians are not allowed to pass, 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 is flashing, vehicles and pedestrians can pass under the principle of ensuring safety. 4, cycling safety knowledge China is known as the "Kingdom of bicycles", is the world's largest bicycle country.
However, bicycles are simple in structure, fall down when touched, and have poor stability, so they are the weakest form of transportation. In traffic accidents, non-motorized vehicles (mainly bicycles) rank first in the number of injuries and second in the number of casualties.
In our country, children and young people aged 12 years old, can start the bicycle on the road, and to comply with traffic rules in the slow lane riding. Recognize the light signals Command light signals When the green light is on, 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 is flashing, pedestrians must be in order to ensure the safety of the principle of passage.
Pedestrians must comply with the provisions of pedestrians must walk in the sidewalk, no sidewalks on the right side of the walkway; crossing the road must take the crosswalk; through the crosswalk controlled by traffic signals, must comply with the provisions of the signals; through the crosswalk not controlled by traffic signals, to look to the right and left, pay attention to the vehicles to and from the vehicles are not allowed to chase, running; there is no crosswalk, must be straight through the vehicles are not allowed to approach suddenly crossing; people walking across the road; the vehicles are not allowed to approach the crosswalk suddenly crossing the road. When there is no crosswalk, you must go straight through, and do not cross suddenly when vehicles are approaching; if there is a pedestrian bridge or tunnel, you must take the pedestrian bridge or tunnel; you are not allowed to climb the guardrail or isolation barriers along the roadside and in the road, and you are not allowed to push or pickpocket the car, chase after the car, forcibly stop the car, or throw objects to hit the car on the road. What safety matters should I pay attention to when riding a bicycle? Riding a bicycle out than walking, unsafe factors increased, need to pay attention to the safety matters are as follows: 1. To often overhaul the bike, keep the car in good condition.
Whether the brake and bell are sensitive and normal is especially important. 2. Bicycle model size should be appropriate, do not ride children's toy cars on the street.
Don't ride a large car with a small person. 3. Do not go to school on the road to ride a bicycle; children under 12 years old, do not ride a bicycle on the street.
4. Riding a bicycle in the non-motorized lane on the right, not against the traffic; turn not rush to turn hard, to slow down in advance, see the surrounding situation, with a clear gesture to signal before turning. 5. Through the intersection, to slow down, pay attention to pedestrians, vehicles; do not run the red light, the red light to stop and wait, wait for the green light and then continue to move forward.
6. Don't spread your hands when you ride, don't ride with more people, don't climb on each other's backs, don't chase each other, and don't fool around. 7. Do not climb on motor vehicles, do not carry heavy things, do not ride with people, do not wear headphones while riding to listen to the radio.
The song of common sense of elementary school students safety (a) encounter bandits 110, bandit police phone to remember, clever and dexterous to maneuver, the bandits were captured quickly; private river, not safe, to prevent dizziness and spasms, a river of water can not drink, young people go to the Yellow Springs; receive hot water, be careful, pots and bottles turned over scalded body, misuse of time, money and grief, the medical skin is not proportional; the river rises, do not be forced to pass, show off the strong and brave will invite disaster, the rain passes through the river, and the river is not safe. The river rises, do not be forced to cross, strong and heroic will attract disaster, walk around the road to safety, rain after clearing the family happy; over the courtyard, do not tease the dog, call adults to drive the dog, do not play smart, the dog bite is dangerous; hot days, walk remote, remember not to drink raw water.
7. Safety tips
Residents of the spring safety precautionary knowledge how to prevent gas poisoning Gas fuel used in the home, such as gas, liquefied petroleum gas, methane gas, etc., are poisonous gases, all contain carbon monoxide and other substances harmful to the human body.
Once the human body inhaled a high concentration of these gases, it will be fainted, if not rescued in time, will cause death. The key to preventing gas poisoning is to eliminate the leakage of these gaseous fuels used at home.
It should be emphasized that when using gaseous fuels, the environment should be well ventilated. This way, in case of a small leakage of gaseous fuels, there will still be enough oxygen for people to breathe without causing serious poisoning.
Families using coal stoves in rural areas should also prevent poisoning from occurring if the stove is left in the bedroom overnight. If the stove is placed in the kitchen or living room, do not close the doors and windows tightly when you go to bed, it is best to put the stove outdoors at night, or extinguish it to remove the hidden danger.
Especially in winter, do not sleep next to the coal stove to warm up at night. Otherwise, it will be too late to cause a tragedy.
How to rescue gas poisoning If you find someone with gas poisoning, do not press any electrical switch to avoid sparks caused by the explosion. You should first open the window to make the room ventilated, and then the poisoned person quickly moved to the outside ventilation, unlock its collar buckle, let it breathe fresh air.
Be careful not to let the cold, otherwise, it may make their body temperature drop, cardiac arrest. If the poisoned person can drink water, you can feed him hot sugar tea, and pay attention to warmth, not with a cold towel on the head, not to pour cold water.
Poisoners breathing difficulties or just stopped breathing, should immediately carry out artificial respiration or chest heart *** first aid, at the same time to call the medical rescue unit, or ask neighbors to help, the patient sent to the hospital for treatment. Of course, in the rescue at the same time, as soon as possible to identify the cause of gas leakage, and to be plugged, lest other people again poisoning victims.
How to safely use the hot pot Users should pay attention to the quality of the product when purchasing the hot pot, to prevent the purchase of untested poor quality products. Problems found, do not disassemble and modification, should be sent to the original manufacturer and maintenance point overhaul.
Before using the hot pot, we should first familiarize ourselves with the use of methods and safety knowledge. If you are using a carbon hot pot, you should put a plate underneath the hot pot and put less water or other insulating materials to prevent the high temperature from baking the table or even causing a fire.
If you are using a liquefied petroleum gas (gas) hot pot, you should prevent gas leakage when using it. After ignition, pay attention to the combustion situation at any time to adjust the flame, to prevent the soup boiling overflow, fire running gas, resulting in gas poisoning or fire and explosion accidents, do not use to cut off the power supply, the power cord should be connected to the pot first, and then connected to the power supply (cut off the power supply and vice versa), do not make the food overflow, if the overflow, the power supply should be disconnected first, and then wiped clean; hot pot to cut off the power supply after the pot to be used up, and then the pot to be washed, dry, and placed in a dry and ventilated place to save.
Electric and gas hot pot after use, be sure to cut off the power or gas source, charcoal hot pot to safely handle charcoal ash. Alcohol hot pot in the remaining alcohol, to be poured into the container, placed in a safe place, to prevent children playing caused by fire.
Prevention of electric blankets caused by fire The elderly and frail people in the arrival of cold spells like to use electric blankets, but electric blankets are continuously energized for too long, such as no thermostatic insurance device, easy to cause fire accidents. In addition, the electric blanket is rubbed for a long time and break, will also cause a fire.
To prevent electric blankets from causing fires, first of all, pay attention to insulation, prevent short circuit. If the electric blanket is damaged, it should not be dismantled or repaired, but should be checked and repaired by an electrician.
In order to prevent a moment of negligence and forget to cut off the power supply, you can use a three-way plug, one end of the lamp, one end connected to the electric blanket, so that the electric blanket will be energized to warm up at night when the lamp is turned on, and then turn off the lamp after sleeping, the electric blanket will also be powered off. It is best not to use electric blankets to prevent children from bedwetting and electrocution.
The electric blanket should avoid folding and getting damp as much as possible. If you don't use the electric blanket for a long time, you need to check carefully whether there is any leakage phenomenon.
Once the electric blanket fire, first cut off the power, and then try to put out the fire. The first thing you need to do is to check that you're not using a blanket to make sure you're not using it.
