Safe use of liquefied petroleum gas First, liquefied petroleum gas cookers should not be placed in bedrooms, offices, balconies, warehouses, auditoriums and other public places to prevent air leakage and fire.

Second, correctly grasp the use of the switch, wait for the fire, don't wait for the gas, remember to turn off the valve and switch after use, and replace the valve in time if it is broken. Don't let children use cookers or play with switches at will.

Third, when using liquefied gas, someone should guard and stay away. Pay attention to adjust the size of the fire head at any time to prevent the soup from overflowing and extinguishing the flame or being blown out by the wind, resulting in air leakage. Fourth, liquefied gas tanks should be upright, not upside down, not to mention boiling water or baking with fire.

Fifth, if gas leaks, measures should be taken immediately: open doors and windows, ventilate with fans (but not electric fans), and then find the leaking part. Basic knowledge of fire fighting (1) isolation method: this is a method to eliminate combustible materials.

(2) Asphyxiation method: prevent air from flowing into the combustion zone, reduce the oxygen content in the air, and make the fire source go out under the condition of insufficient oxygen. (3) cooling method: spray water or other fire extinguishing agents on the combustible materials to lower the temperature of the combustible materials below the ignition point and force the combustion of the materials to stop; Or spray water and fire extinguishing agent to combustible materials near the fire source to reduce the temperature of combustible materials and avoid the expansion of the fire.

(4) inhibition method. In case of fire alarm, call the fire brigade immediately "1 19" and organize personnel to put out the fire immediately.

When fighting, save people first, then save people, focus first, then put out the fire, and pay attention to disaster relief with the wind, especially in the field fire. When putting out a fire, generally use local materials, such as water, sand, soil and other fire extinguishing equipment, especially try to control the spread of the fire.

It is strictly forbidden to mobilize and organize primary and secondary school students to participate in forest fire fighting. At the same time, it is necessary to strengthen the education and management of primary and secondary school students who are not allowed to participate in forest fire fighting. In case of spontaneous forest fire fighting, schools and relevant departments should dissuade them in time to prevent unnecessary casualties.

Pay attention to the following points when giving an alarm: (1) Explain the district (county), street, town or village where the fire unit or household is located. When there are duplicate names, distinguish them so as not to find the wrong one.

There are similar or confusing words in place names or unit names, which should be emphasized and clarified. (2) You must quote the names of all units and streets, and do not use abbreviations.

(3) Explain what substance is on fire and the size of the fire. This is convenient for the fire brigade to decide the vehicles and police force it dispatched according to the burning object and the size of the fire.

(4) explain the name and telephone number of the alarm person. Because the telephone used by the alarm person is often close to the fire site, the fire brigade can use this telephone to ask the alarm person about the development of the fire site before the dispatched force arrives, which is convenient for command and mobilization. (5) After the alarm, people familiar with the situation should go to the nearest intersection to meet the fire truck or guide the passage, and provide the location of water source so as to quickly put out the fire.

To escape from a building fire, we should calmly analyze and not act blindly. Be clear about your floor, remember the location and direction of stairs and doors; Analyze the surrounding fire, don't blindly open the window to open the door, otherwise it will add fuel to the fire, and don't blindly run and jump off the building, causing undue casualties.

The second is to choose a good way to escape, and don't panic. If you must rush out of the building from fireworks, wrap your head and face, especially your mouth and nose, with wet towels, clothes and other clothes, and walk in a low posture to avoid suffocation.

If there is a fire downstairs, but it is not big, rush out of the stairs. If the stairs are broken and can't be washed out, you can use the tiger window, balcony and leaky pipe of the house, or tie them to solid doors and windows and heavy objects with ropes (which can be torn into ropes by clothes or bedding) and slide down from the windows.

If you are forced to jump from the second or third floor without the above methods, you should also throw some quilts and other things at this position to increase the buffer, and then press the windowsill to reduce the falling height and ensure that your feet land. If all kinds of escape routes are cut off by fire, retreat indoors and close the doors and windows. If possible, water the doors and windows to slow down the fire. You can also throw things out of the window and use a flashlight for help.

There are no elevators in the burning building. If household appliances or gas stoves catch fire, turn off the power supply or the switch of the cooker quickly, and do not splash water on the appliances, wires or gas stoves.

(2) Self-help in case of personal fire. If you are on fire, don't run, or it will burn more and more brightly.

You can try to take off your coat and hat, but you can tear it off and throw it away before it's too late. If it is too late, you can lie on the ground and roll, or jump into ponds, pools and rivers.

If there are other people present, you can use wet sacks, blankets, etc. Put fire on people. Never spray a fire extinguisher directly on a burning person, because drugs can cause wound infection. The third part is the safety knowledge of collective activities inside and outside the school. 1. To organize students to participate in labor and social practice, students must be given safety education in advance, with special emphasis on observing discipline, obeying management and obeying orders.

Activities are carried out under the guidance of teachers, and it is not appropriate to organize students to participate in special operations such as toxic, harmful, high temperature and heavy physical labor. (a), to prevent electric shock 1, don't use wet hands, wet cloth to touch, wipe the electrical shell, don't hang clothes or objects on the wire, or directly hang the wire on the nail.

2. Report the damaged wires, lamp holders, switches and sockets in time and ask someone to repair them. Do not touch them. 3. In case of fire caused by electrical equipment, cut off the power supply quickly and then put out the fire.

4, found someone get an electric shock, to get an electric shock from the power supply as soon as possible, and then take other rescue measures. Stay away from high-voltage charged bodies.

(2), to prevent falling objects 1, enter the construction site, must walk on the road in accordance with the provisions, must wear a helmet. 2, lifting loading and unloading, it is forbidden to stand under the lifting items, traffic.

Second, off-campus collective activities should pay attention to 1. Organizing students to participate in off-campus collective activities must be studied by school leaders in advance, carefully planned and strictly organized, and led by school leaders or teachers. It is necessary to send people to visit the activity site and environment in advance.

It is necessary to establish a system for reporting large-scale collective outing activities to higher authorities for approval. 2. If vehicles need to be used during the activity, they must meet the safety requirements, and must not be overloaded. They must not take cars or boats driven by people without driver's licenses.

3. Places, buildings and facilities participating in off-campus collective activities must be solid and safe, with smooth entrances and exits, complete and effective fire-fighting equipment in the field and properly placed. 4. Go to the browsing area and amusement places for activities.

More kindergarten safety knowledge >> What kind of kindergarten is the problem in kindergarten safety education? Children are curious, active, exploratory, lack of life experience and poor self-protection ability. They are the most vulnerable and vulnerable group among social members.

Therefore, children's safety education is very important. Kindergartens must give priority to protecting children's lives and promoting their health.

It should be said that most kindergartens attach great importance to children's safety, but the effect of children's safety education at present is not satisfactory. A survey in 2006 showed that 76.6% of children had the experience of falling or bumping in the game. 66.8% of the children had the experience of falling out of bed; 25.8% children have the experience of falling down stairs.

20 10 vicious safety incidents have occurred continuously in kindergartens in China, and children's safety accidents have occurred frequently. Accidental injury has become the first killer threatening children's life safety and healthy growth. At present, there are two main problems in kindergarten safety education: 1, which emphasizes protection, ignoring all-round protection of children by parents and teachers, and thinks that less activity can reduce dangerous accidents.

Some parks even reduce children's time for outdoor activities, depriving children of the opportunity to improve their self-protection ability through practical exercise. Although teachers and parents are doing their best to care for children and try their best to reduce accidents, we should clearly realize that adults' protection for children is limited after all, so while paying attention to and protecting children, it is more important to teach children the necessary safety knowledge and enhance their awareness and ability of self-protection.

2. Pay attention to the instillation of safety knowledge, rather than the training of safe behavior. In the daily safety education, most of the teachers are teaching children what to do and what not to do.
