Dear teachers and students:
As the temperature drops, the weather is cold, the climate is dry, it is the season of fire accidents, traffic accidents and personal injury accidents, in order to ensure the safety and stability of the school, prevent the occurrence of various accidents, and strive to create a safe environment that satisfies teachers and students, please pay attention to the following points:
1. Pay attention to traffic safety: The flexibility of human joints is poor in winter, and the response is relatively slow, so you should pay attention to traffic safety on the way to and from school. Walk on the sidewalk, and walk on the right side of the road where there is no sidewalk;When passing through the intersection or crossing the road, you should slow down, and for the safety of yourself and others, I hope that students must pay attention to traffic safety and consciously abide by traffic laws.
2. Pay attention to sports safety. Before going to physical education class, you should be fully prepared for the activity, and do not collide violently during sports to avoid bumps or falls. No chasing and fighting, no yelling, no grouping, no crowding, and orderly walking.
3. Pay attention to harmonious interactions. When encountering conflicts between classmates, you must be calm and rational, and do not use fists instead of reasoning, which will bring bad consequences to yourself and your classmates. If you can't solve the conflict by yourself, you must seek the help of the teacher to solve it.
Fourth, fire safety: since entering the autumn and winter, the weather is dry and dry, and the fire hazard is very large
1. Do not bring matches, lighters and other fireworks, firecrackers and other flammable and explosive materials into the campus to avoid accidents.
2. Consciously take care of all kinds of fire protection facilities on campus, such as fire hydrants, fire extinguishers, etc.
3. In the classroom, it is not allowed to use electrical equipment without authorization.
4. After school, please turn off the electrical appliances at will.
Remind everyone: the weather is cold, students should add more clothes, and don't suffer from the cold for the so-called demeanor.
Students, life is beautiful, life is colorful, and the premise of having all this is safety. Therefore, we must always strengthen our safety awareness, strive to enhance our self-defense ability, and make sure that the alarm bell rings for a long time!Let's create our safe campus together!
This concludes my speech under the national flag, thank you!
Students: The topic of my speech today is: Fire safety is everyone's responsibility.
Our lives are inseparable, but if the fire is not used properly or poorly managed, it will cause fire, which seriously threatens our lives and property and causes huge losses to the construction and development of the country.
Here I would like to propose the following fire prevention points:
Primary school students are not allowed to play with fire and are not allowed to carry fire with them: 1: Do not bring matches or lighters and other fires;II;It is forbidden to ignite fire at will, and it is forbidden to use fire in places where flammable materials are stored;3. Firecrackers, fireworks and other dangerous items are not allowed to be set off in public places, and it is not allowed to throw lit firecrackers indiscriminately. At the scene of the fire, elementary school students and other minors should flee in an orderly manner.
1. If there is a refuge floor or evacuation staircase, you can enter the refuge floor first or evacuate to a safe place by the evacuation staircase.
2. If the floor is already on fire, but the stairs have not yet burned out, and the fire is not very violent, you can put on a water-soaked quilt and quickly rush down from the upper floor.
3. In the case of a fire in a multi-storey building, if the stairs have been burned or the fire is quite fierce, you can use the balcony, downspout or bamboo poles of the house to escape.
4. If all kinds of escape routes are cut off, you should retreat indoors and close the doors and windows. When possible, water can be poured on doors and windows to delay the spread of fire. At the same time, small objects can be thrown outside, and at night, a flashlight can be turned out to send out a distress signal.
5. If life is seriously threatened and there is no other way to save yourself, you can use ropes or sheets to tear them into strips and connect them, tie one end tightly to a firm door pane or other heavy objects, and then slide down the rope or cloth strips.
6. If the above-mentioned self-rescue methods are taken unconditionally, and the time is very urgent, the threat of fireworks is serious, and you are forced to jump off the building, you can first throw some quilts and other objects to the ground to increase the buffer, and then hold the window sill to slide down to reduce the height of the jump, and ensure that your feet land first.
Seventh, it is necessary to carry forward the spirit of mutual assistance and help the elderly, children, and patients to evacuate first. For people with reduced mobility, they can be bandaged with quilts, blankets, etc., and hung with ropes and strips of cloth.
Thank you!Comrades:
The weather is getting colder, and winter is fast approaching. The winter is cold, the fluidity of the car fuel becomes poor, the viscosity of the lubricating oil increases, and the cooling water is easy to freeze, therefore, the use of the car under such conditions in winter, the method is extremely important, and the improper use method will reduce the service life of the car, and even lead to accidents, so the winter maintenance of the car is very important.
Use warm water to wash the vehicle
In winter, you can't use cold water to flush your car directly, especially not your engine. Because the temperature of the front of the car is high after the engine heats up, washing it with cold water will cause rapid cooling, which will cause great damage to the surface paint. After washing the car, open the window and dry the surroundings, especially the door cracks, because the water is easy to freeze in winter, and there is water residue in the door cracks, which is easy to freeze the car door. Do not force the windows to open and close when they are frozen, and wait for the ice to melt naturally before using them.
The engine oil should be changed in time
The viscosity of motor oil varies with temperature. With the drop of temperature, the fluidity of the engine oil will become worse, and the starting, power and economy of the engine will also decrease significantly, therefore, in order to prevent the difficulty of engine starting, when the winter comes, the oil pan and the oil in the air compressor should be replaced with the engine oil in winterReplace the gear oil in the transmission, transfer case, differential, and steering gear with the gear oil used in winterAfter the hub bearing is cleaned, the bearing oil with lower viscosity is added.
The battery should be replaced in time
The life of the general battery is two to three years, if it is close to the service life, it is best to replace it with a new one, at the same time, to remove the oxide on the battery electrode pile in time, supplement the distilled water, and maintain its normal voltage and liquid level. When leaving the car, it is best to ignite the engine first to make the engine work before turning on the lights, radio and other electrical appliances, and when stopping, you must first turn off all kinds of electrical appliances, and finally turn off the engine.
Ordinary water has been added to the antifreeze and must be replaced
Vehicles that use water as coolant should first clean the engine cooling system to remove impurities such as scale, and then add antifreeze in the prescribed proportion. If you have ever added normal water to the antifreeze, the antifreeze must be replaced. The best antifreeze is not expensive, the domestic antifreeze is about more than ten yuan a barrel, and the relatively high quality is also about 100 yuan. A car basically needs a bucket of antifreeze. The temperature of the winter night in the north is low, so the glass water should also be replaced with anti-freezing winter glass water, or add an appropriate proportion of alcohol to the glass water, which can also achieve the purpose of reducing the freezing point and anti-freezing.
Wiping the inner surface of the windshield prevents fogging
Before entering the winter, it is necessary to focus on checking the heating device, such as the windshield, side window air outlet, rear window electric heater, etc., so that it is in good condition, so as to avoid ice and frost on the window in winter, obstructing the line of sight and affecting safety. If you want to quickly defog it, you can turn on the air conditioner switch;The use of a special glass anti-fogging agent is also very effective;If there is no special glass anti-fogging agent, you can also use household glass lotion or detergent instead, and wipe the inner surface of the windshield, which can also play an anti-fog role.
Broadcast script for the maintenance of the troop tracked vehicles during the winter season
1.Develop good inspection Xi. According to different use conditions, the oil should be checked regularly during routine and daily maintenance, and if the oil level exceeds the lower limit, it should be added in time. Vehicles with a long service life and mileage and often used in harsh conditions should be inspected more frequently. In this way, even if the vehicle has the situation of "burning engine oil", it can also be "detected early and early" to reduce maintenance costs.
2.Choose better quality gasoline. After the additives in gasoline are oxidized, a gelatinous substance is formed, and after entering the combustion chamber through the fuel injector, carbon deposits will be formed in the intake valve, piston top, piston ring groove, combustion chamber, spark plug and other parts, which will aggravate the aging of these parts and cause "engine oil burning". Therefore, the choice of better quality gasoline can reduce the phenomenon of "burning engine oil".
3.Maintain your vehicle regularly. The maintenance cycle of the vehicle is formulated according to the normal driving condition of the car, and the vehicle with poor use conditions should shorten the maintenance cycle and the specified kilometers according to the actual situation.
Well, that's the end of today's broadcast, and we'll see you tomorrow!Thanks for listening!
