L. Know the main switch of power supply and learn to turn off the main power supply in an emergency.

2. touch and probe the inside of the power socket without hands or conductive objects (such as metal products such as iron wires, nails and pins).

3. Don't touch the appliance with wet hands or wipe it with wet cloth.

4. Unplug the electrical appliance after use; Don't pull the wire hard when plugging and unplugging the power plug to prevent the insulation layer of the wire from being damaged and causing electric shock; The insulation of the wire is peeling off, so it is necessary to replace the new wire in time or wrap it with insulating tape.

5. If someone gets an electric shock, try to turn off the power in time; Or use dry wooden sticks and other things to separate the electrocuted person from the charged electrical appliances, and don't use your hands to save people directly; Younger students should call adults for help when they encounter this situation, and don't handle it by themselves to prevent electric shock.

6. Do not disassemble or install power lines, sockets and plugs at will. Even simple things such as installing a light bulb should be turned off first and carried out under the guidance of parents.

This is not only the requirement of competition, but also the guarantee of safety. Especially when sprinting towards the finish line, we should abide by the rules, because at this time, people's physical momentum is great, their energy is concentrated in the competition, and they are mentally unprepared. Once they stumble over each other, they may be seriously injured.

2. In long jump, the run-up and take-off must be strictly guided by the teacher. Before take-off, you should step on the wooden springboard and fall into the bunker after take-off. This is not only the technical essentials of long jump training, but also the necessary measures to protect physical safety.

3. In throwing training, such as throwing grenades, shot put, discus, javelin, etc., it must be done according to the teacher's password, and it is forbidden to do so without any carelessness. Some of these sports equipment are hard and heavy, and some are equipped with sharp metal heads at the front end. If you act without authorization, you may hit others or yourself, causing injuries and even life-threatening.

4. During the training of single, parallel bars and high jump, a mat with the required thickness must be prepared under the equipment. If you jump directly to the hard ground, your leg joints or the back of your head will be injured. When doing single and parallel bars, we should take all kinds of effective methods to avoid slipping when holding the bars with both hands, and to avoid falling off the bars and injuring our bodies.

5. When doing jumping training such as vault and box jumping, there should be a springboard in front of the equipment, a protective pad behind the equipment, and teachers and classmates should stand beside the equipment for protection.

6. For mat sports such as forward and backward tumbling, push-ups, sit-ups, etc., you should be serious when doing the movements, and you should not fight to avoid sprains.

1. Help yourself or each other immediately, and don't panic or run, which will accelerate the absorption and spread of toxins.

2. immediately tie it with a belt, cloth belt, handkerchief, rope and other things at a distance of 3-5 cm from the wound to slow down the spread of toxin. Relax for 2-3 minutes every 2 minutes to avoid limb ischemia and necrosis.

3. Wash the wound with clear water, preferably with normal saline or potassium permanganate solution. At this time, if any fangs are found, they must be pulled out.

4. After washing the wound, use a sterilized or clean blade to make a cross-shaped incision centering on the two fangs marks. The incision should not be too deep, as long as the venom can be discharged by cutting under the skin.

5. If possible, you can repeatedly suck the wound with cupping or breast pump to suck out the venom. You can also inhale through your mouth in case of emergency, but the person who inhales must have no ulceration in his mouth and gargle fully after spitting out the venom. After inhalation, the wound should be warmed to facilitate the venom to continue to flow out.

6. It can ignite matches, burn wounds and destroy snake venom.

7. Take all kinds of snake medicine as soon as possible, and it will be ineffective to take it after 24 hours of biting. At the same time, the tablets can be made into paste with warm water or saliva, and applied to 2 cm around the wound, and the wound should not be bandaged.

8. After treatment, it should be sent to a nearby hospital immediately.

what if I am bitten by a dog?

being bitten by a dog is harmful to people, because the dog's teeth are full of various germs and viruses, which can easily invade the human body through the wound, causing diseases, and even causing colds and death. If you are bitten by a mad dog, rabies will be caused by rabies virus, and the mortality rate of rabies is very high. Therefore, being bitten by a dog must not be underestimated, and emergency measures must be taken:

1. It is difficult to distinguish whether you are bitten by a mad dog under normal circumstances, so once you are bitten by a dog, you should treat it as a mad dog bite.

Fracture refers to the partial or complete fracture of human skeleton, and most fractures are caused by strong impact. After fracture, the fracture site is painful, accompanied by swelling, blood stasis and deformation, and people's activities are restricted, so they can't bear the load. In serious cases, there will be bleeding, shock, infection and visceral injury. How to deal with a fracture in an emergency?

1. Make the patient lie flat, don't move the patient blindly, let alone pull and massage the injured part.

2. Check the injured part, select branches, boards and sticks from local materials in time, and fix the injured part to prevent the injury from getting worse.

3. When there is nothing for fixing, the injured upper limb can be hung and fixed on its chest with handkerchiefs and cloth strips, and the lower limb can be tied and fixed with the uninjured lower limb.

4. For open fractures (that is, the limb or mucosa at the fracture site is broken and the bone is exposed), attention should be paid to keeping the wound clean to prevent infection.

5. After emergency treatment, immediately send it to the hospital for treatment, and pay attention not to collide with the injured part during transportation. avoid
