Matters needing attention in summer homework

Question 1: Safety precautions in summer. A, thunderstorm safety knowledge

Summer is a season with frequent thunderstorms, and lightning casualties often occur. Therefore, everyone should attach great importance to their own safety and master the necessary safety protection knowledge in thunderstorm days.

1, pay attention to close the doors and windows, cut off the power supply of household appliances, and unplug them; Do not get close to conductive objects such as water pipes and heating pipes; Don't stand under the lamp cap line; Don't take a shower under the shower head; Don't use your cell phone.

2. Don't stay on the high-rise platform; Don't gather, run or shout in the corridor.

3. Don't enter isolated shacks, sentry boxes and other low-rise buildings; Don't hide under the big tree to avoid the thunderstorm.

4. Don't open an umbrella and hold high other metal objects in the wild; Don't run in the wilderness; * * * Wear wet clothes, shoes, hats, etc.

5. Don't ride a bike; No outdoor ball games;

6. By car, train, etc. Don't stick your head and hands out of the window.

7. Don't connect the wires for drying clothes and bedding to windows and doors.

8. In case of sudden lightning, you should immediately lower your height, put your feet together, put your hands on your knees, and don't touch the ground with other parts of your body to reduce the damage caused by stepping voltage.

9. Once the human body is struck by lightning, it often appears "suspended animation". At this time, mouth-to-mouth resuscitation and extracorporeal heart surgery should be carried out, which can often bring miracles. Call 120 for emergency treatment at the same time.

Second, food hygiene and safety knowledge

In summer, the weather is hot, the temperature is high, the humidity is high, the reproduction speed of pathogenic microorganisms is accelerated, food is easy to rot and deteriorate, and bacterial food poisoning and intestinal infectious diseases are easy to occur. Therefore, students should pay great attention to food hygiene and safety to prevent food-borne diseases such as food poisoning.

1. When buying food, carefully check the name, address, production date, shelf life, etc. Try to choose fresh food with short storage time, and don't buy "three noes" food and expired food.

2. Don't buy untested meat, poultry with unknown cause of death and aquatic products. Don't buy cooked meat, cold salad, cold noodles and other foods sold by roadside "unlicensed" vendors.

3. The food safety risk of eating raw aquatic products in summer is high. Eat less or not eat raw aquatic products such as grilled shrimp, clam, drunken shrimp and drunken crab.

4. Processed stews and cooked meat foods should not be stored for more than 2 hours, and should be fully heated for more than 2 hours.

Vegetables and fruits processed with cold salad must be washed and disinfected before eating. Don't eat fruits, vegetables and wild food without permission. The melons and fruits eaten directly should be thoroughly washed with clear water and peeled as much as possible.

6. When eating out, you should choose catering units with good sanitary conditions and valid food hygiene licenses. Wash your hands before meals, use public chopsticks as much as possible, and advocate separate meals. When eating, you should pay attention to distinguish whether the food has gone bad and whether there are foreign bodies. Don't eat illegal food, and don't overeat.

7. The temperature is high in summer. Eating cold drinks at the right time can relieve summer heat and quench thirst, which is good for your health. Cold drinks should not be eaten too much, and cold drinks should not be eaten when sweating a lot, before and after meals, or after drinking hot drinks. When buying cold drinks, carefully check the production date and shelf life, and try to choose products with close factory date; Don't drink unclean water or raw tap water.

8. In case of suspected food poisoning, immediately stop eating suspicious food, organize treatment as soon as possible, and report to the local health administrative department so as to get timely investigation and treatment, and avoid food poisoning incidents that cannot be identified due to time delay.

Third, common sense of heatstroke prevention safety

Heatstroke is one of the common acute fevers in hot summer. Mild patients may have dizziness, headache, nausea, thirst, sweating, palpitations, flushing, body temperature may rise above 38℃, and even collapse symptoms such as decreased blood pressure and accelerated pulse. In severe cases, the symptoms are high fever (body temperature above 4 1℃), anhidrosis, vague speech consciousness, hand and foot convulsions and disturbance of consciousness. In severe cases, there are critical diseases such as shock, heart failure, pulmonary edema and brain edema. So everyone should pay attention to heatstroke prevention.

1. Wear loose clothes with good air permeability and light color; Wear an insulated sun hat; Drink more salt and boiled water; The indoor and outdoor temperature difference of air conditioner should not be too large. The indoor and outdoor temperature difference of air conditioner shall not exceed 5 degrees; Prepare heatstroke prevention drugs such as Dan, cooling oil, essential balm, ten drops of water and mint tablets.

2. When heatstroke occurs, the patient should be carried to a cool and ventilated place to lie down and rest first, then unbutton the button for the patient, apply a cold water towel to the patient's head and neck, and let the patient drink more water (preferably warm salt water or watermelon juice), and take heatstroke prevention drugs such as Ren Dan and ten drops of water. If the condition is serious, you should be sent to the hospital for treatment or call 120 emergency number.

Question 2: What problems should we pay attention to when going out to do homework in summer? Hello, pay attention to the following aspects: 1. Pay attention to sun protection. 2. Pay attention to hydration. 3. Diet should be light. 4. Take some commonly used drugs such as elixir and toilet water. 5. Avoid long-term high-intensity work.

Hope to adopt

Question 3: What should I pay attention to when doing outdoor homework in summer? If you don't store enough heatstroke prevention articles, the consequences of heatstroke may be very serious. Another point is that sun protection is mainly caused by ultraviolet rays, which are harmful to the skin. If you are often exposed to ultraviolet rays, it is easy to get skin cancer ... Pay attention to drinking more water 1 1 -3: 00, and pay attention to summer vacation in direct sunlight.

Question 4: What are the precautions for high temperature operation in chemical plants in summer? What problems should be paid attention to in summer heatstroke prevention? In the hot summer, many people will feel unwell because of the high temperature, and in severe cases, heatstroke will occur. Infants, the elderly, pregnant women, patients with cardiovascular diseases, patients with infectious diseases and diabetics are all high-risk groups of heatstroke. So, how to prevent heatstroke in summer? Wear light-colored clothes: You should wear white, light-colored or plain clothes when going out in summer, but not black or blue clothes, because white, light-colored or plain clothes absorb heat slowly and dissipate heat quickly, and wear cool clothes, which is not easy to suffer from heatstroke; Black or blue clothes absorb heat quickly, dissipate heat slowly, and are sultry and prone to heatstroke. Drink more salty boiled water: it is hot every day in summer, sweating more, and the salt in the body is reduced, so the osmotic pressure in the body will be unbalanced, leading to heatstroke. Drinking more boiled water or salty tea can replenish the salt lost in the body, thus preventing heatstroke. When drinking salt water, you need to drink a small amount of salt water many times to prevent heatstroke. Take heatstroke medicine: heatstroke is my favorite in hot weather. Therefore, you should take some heatstroke prevention drugs when you go out in summer. Such as Ren Dan, cooling oil, tiger balm, essential oil, ten drops of water, mint tablets, Huoxiang Zhengqi water, etc. In addition, in summer, we should also pay attention not to stay in the hot sun and high temperature environment for a long time, and prepare more cool drinks and heatstroke prevention equipment such as sunglasses and sun hats. Once heatstroke occurs, the patient should be carried to a cool and ventilated place to lie down and rest, then the patient's clothes should be unbuttoned, and a cold water towel should be applied to the patient's head and neck, so that the patient can take some pills or ten drops of water. If the patient faints, you can pinch the patient's Renzhong point with your fingers or acupuncture Xuan Shi point with your fingertips, and then send the patient to a nearby hospital for treatment after he gets better. Methods of heatstroke prevention and cooling in summer and precautions for heatstroke prevention and cooling at home in summer 1. In summer, people have their own ingenious ways to deal with the heat and high temperature. But some tricks are people's radical practices, which may damage people's health after enjoying temporary comfort. Therefore, when dealing with the heat and high temperature, we should pay attention to the following five disadvantages. 1. Don't cool down too fast. When sweating profusely, many people think it's cool to take off their clothes and put them in front of the fan, or turn on the tap and let the cold water rush down to realize "rapid cooling". As we all know, this "rapid cooling" method often leads to "being happy for a while, being uncomfortable for a few days" and even causing various diseases. 2. The air conditioner should not be too cold. Medical meteorologists found through experiments that it is necessary to constantly adjust the room temperature in order to gradually adapt to the great changes in temperature. The correct way is: the indoor temperature should be constantly changing between 26℃ and 29℃, which is beneficial to health. 3. Drinking water should not be excessive. Drinking more water is a good measure to prevent heatstroke, but drinking too much water can also lead to poisoning. Especially in the hot summer, after people sweat a lot, electrolytes such as sodium salt in the body are also lost. If you drink plenty of boiled water at this time without supplementing salt, muscle twitching or muscle spasmodic pain will occur. 4. clothes should not be exposed. Health experts point out that only when the skin temperature is higher than the ambient temperature can bare skin cool down by increasing skin radiation and conducting heat dissipation. In hot summer, the highest temperature is generally close to or higher than 37℃, so the skin can't dissipate heat, but absorbs heat from the external environment, so it will feel hotter if you are shirtless in summer. 5. Don't wear dark sunglasses. Many people think that the darker sunglasses are, the better they can protect their eyes. In fact, the darker the lens, the worse the visibility will be, and the eyes will be damaged by the difficulty of seeing. Therefore, the standard of choosing sunglasses in summer should be that the lens can transmit 30% visible light, and gray and green are the best. Second, the prevention of heatstroke: heatstroke is a common emergency in summer, and strengthening prevention can greatly reduce the incidence. The prevention of heatstroke should pay attention to the following points: 1, adequate sleep. Arrange the rest time reasonably, ensure enough sleep to maintain sufficient physical strength, and achieve the purpose of heatstroke prevention and cooling. 2. A scientific and reasonable diet. Eat more vegetables, fruits and proper animal protein and fat to supplement physical exertion. Never go on a diet. 3. Take sun protection measures. Outdoor activities should avoid direct sunlight on the head and direct absorption of radiant heat by the skin. Wear a hat and loose clothes. 4. Drink water reasonably. Drink 3 liters to 6 liters per day, preferably containing 0.3%-0.5% sodium chloride. Avoid drinking plenty of water before and after meals and before and after strenuous exercise. Third, the hot summer is coming. In recent years, many families use air conditioners to protect their family life from the extreme heat. But most families still don't use air conditioning. In fact, some simple methods can also make your room cooler. 1, reasonably open and close doors and windows. Many people think that doors and windows should be opened to cool down in summer ... >>

Question 5: What are the precautions for using electricity in summer? Summer is the peak of electricity consumption. No matter refrigerator, air conditioner or water heater, every necessary electrical appliance in summer is an expert in burning electricity. Therefore, in addition to saving electricity at ordinary times, the safety performance of electricity can not be ignored.

1. Don't overload electricity consumption: Before summer comes, you should calculate your total electricity consumption and compare it with the maximum rated current of electricity meter and power cord. If it is not enough, it should be reported to the power supply department in time to increase the capacity of the meter. It is best not to start high-power appliances such as air conditioners and microwave ovens at the same time, otherwise the instantaneous surge current will be too large, which will burn out the electric meter.

2. Be careful when connecting the power supply: in areas with complicated lines, the power supply should be installed by professionals, otherwise it will cause serious consequences. Copper wire and aluminum wire are prohibited. Replace the fuse; Signal transmission lines cannot be used instead of power lines; Medical leucorrhea and transparent belt cannot be used instead of insulating black belt.

3. Don't use "problem" electrical appliances: When electrical appliances are abnormal, such as odor, smoke, vibration, increased noise, etc., stop using them immediately. When the temperature rises, you should immediately cut off the power supply and ask a professional to repair it. Do not disassemble the electrical appliance by yourself, so as not to damage the internal components of the electrical appliance.

4. Place electrical appliances correctly: Place electrical appliances correctly to avoid long-term use. Electrical appliances must be placed in a dry, clean, ventilated place without direct sunlight or darkness. After the electrical appliances are used for a period of time, they should have a proper rest to avoid continuous use for a long time. Flammable articles are prohibited around electrical appliances. It is best to electrify and heat electrical appliances once a week for a long time. Anti-coma, moisture-proof and rust-proof. Many people like to wipe the surface of TV screen with a wet rag when watching TV. This is not correct. Never wipe household appliances with a wet rag when electricity is on. It is best to adjust the electrical equipment to the energy-saving state, the air conditioning temperature should not be too low, and the number of refrigerator doors should be reduced as much as possible. Don't be too bright on the TV or computer.

5. Plug and socket should be matched: the plug of the electrical appliance should be matched with the power socket, and it cannot be forcibly inserted to prevent the socket from being damaged and causing short circuit; It is forbidden to use electrical appliances with damaged appearance or exposed charged body; Do not enter the distribution room without permission, and do not place sundries on the distribution board and electrical equipment; After work, or when you don't use electrical equipment for a long time, please turn off electrical appliances, lights, air conditioners, etc. Don't use electric heating equipment such as induction cooker, rice cooker and electric stove to cook in the hospital; Don't connect too much power equipment, such as air conditioner, microwave oven, etc. , to the mobile terminal board; Avoid placing the wires of the mobile patch panel in places that are easily accessible in daily activities, and avoid placing the mobile patch panel directly on the ground to avoid danger; When cleaning, be careful not to splash water on electrical equipment.

6. Precautions for touching electrical equipment: In summer, people are prone to sweat, the human body resistance is correspondingly reduced, and the safety factor against electric shock is relatively weakened. Pay more attention to safety when touching electrical equipment to avoid electric shock accidents. If you find abnormal noise, smell, smoke, fire, etc. When, should immediately disconnect the power. Here, the online shopping network should remind users to use electricity safely and choose patch panels, switches and sockets with quality assurance.

7, don't use wet hands, wet cloth contact charged lamp holder, switch and socket.

8. The refrigerator should avoid being placed close to the wall: in wet weather, the wall is very wet, and the parts inside the refrigerator are affected by the small holes in the refrigerator, which leads to the humidity inside the refrigerator, so pay attention to the position of the refrigerator.

Keep a certain distance between the refrigerator and the wall, and give priority to a well-ventilated location.

Question 6: What should I pay attention to when working high above the ground in summer? Precautions for aerial work Aerial work is a process with many dangerous sources and high risks in engineering construction. According to relevant data, about 50% of safety accidents in construction are caused by falling from high places or related to aerial work, so it is extremely important to do a good job in safety protection, safety management and safety monitoring of aerial work. When working at heights, corresponding safety protection measures should be formulated and strictly implemented in combination with the engineering characteristics and the surrounding environment of the project under construction. In my opinion, the following points should be paid attention to in aerial work in building construction: (1) The construction organization design and construction scheme compiled at the start of each project should be included in all safety technical measures involved in aerial work in this project, so as to prevent hazards before they happen. And try to take ground operations to reduce all kinds of aerial work. (2) The safety technical problems of aerial work cover a wide range, including general requirements, such as setting up safety signs, setting up safety nets and safety flat nets, and various special safety protection measures. During construction, safety protection measures should be strictly implemented, the principle of "people-oriented" should be adhered to, and work should be carried out on the premise of ensuring the safety of construction personnel. (3) Special types of aerial work personnel generally need to have a physical examination once a year. People suffering from heart disease, hypertension, psychosis, epilepsy, etc. Personnel who are not suitable for aerial work shall not be arranged to engage in this work. (4) Workers working high above the ground should wear neat clothes, but never be shirtless and naked. Wear soft-soled non-slip shoes under your feet, and never wear slippers, hard-soled shoes or shoes with nails. When operating, we must strictly abide by various safety operating rules and labor disciplines, and adhere to the principle of "don't hurt others, don't hurt ourselves, and don't be hurt by others" to ensure safe production. (5) Climbing and hanging operations (such as scaffolder and structural installer) are dangerous. Therefore, such personnel should pass the training and examination, and obtain the operation certificate of special type of work before taking up their posts, and carry out regular training and safety knowledge update education. (6) The materials used for aerial work shall be piled up smoothly, and shall not be placed near the limb or the mouth of the cave, nor shall they hinder the safe passage. Running walkways, access panels and climbing appliances should be cleaned at any time. Dismantled objects, surplus materials and wastes shall be cleaned up and transported away in time, and shall not be placed or discarded down at will. You can't throw objects when passing them. In all construction workplaces, all materials that may fall should be removed first to prevent people from falling. (7) When defects or hidden dangers are found in the safety facilities for aerial work during construction, they must be dealt with immediately. For the hidden dangers that endanger personal safety, the operation should be stopped immediately and rectified. No one is allowed to move or remove all safety protection facilities and safety signs without authorization. Some must be removed or moved due to construction needs, and can only be removed after being approved by the person in charge of construction, and then resumed after completion. (8) Construction personnel should complete the handover procedures for each type of work. Different types of work have different hazards in construction. Construction personnel should provide targeted safety technical disclosure to workers according to different types of work, and resolutely implement the principle of "safety must be managed in production" to ensure safety in the production process. (9) When the main body of the project is under construction, the external scaffold must be synchronized with the main body construction, and the external scaffold must exceed the operating surface1.2m.. In the process of decoration construction, the safety inspection and maintenance of external scaffolding should be strengthened, and the falling objects on the external scaffolding should be cleaned up in time to avoid hurting people. In a word, aerial work is a dangerous job. In the construction site, only by doing a good job in the safety management, safety monitoring and safety prevention of building aerial work, I believe that the occurrence of safety accidents can be greatly reduced, and a safe working environment can be provided for workers, thus improving efficiency and safe production.

Question 7: What do the characteristics and precautions of safety production in summer mean? Frequent rainfall in summer is easy to lead to drowning and leakage, so corresponding preventive measures need to be added;

The temperature is relatively high in summer, which easily leads to heatstroke. Pay attention to cooling and ventilation to reduce the time of high temperature operation;

Lightning damage and high voltage breakdown of lines are prone to occur in lightning weather in summer, so it is necessary to check whether the lightning conductor meets the requirements. ......

Question 8: What should we pay attention to in summer production safety? In summer, when the temperature is too high, people will feel hot, irritable, sweaty and lose more nutrients. In summer, bacteria grow and multiply rapidly, which is the high incidence period of food poisoning, and food safety is particularly important. When eating, pay special attention to the safety and hygiene of food, and pay attention to the following points:

1 food

When we go out to eat, we should choose a safe and hygienic restaurant. First of all, it depends on whether the restaurant holds valid food hygiene licenses and other legal business certificates. If it is an unlicensed restaurant, its sanitary conditions cannot be guaranteed, and the rights and interests of consumers cannot be guaranteed; Then, we can observe the hygiene condition of the restaurant and the personal hygiene condition of the service staff, and we can judge their hygiene condition from the hygiene condition of the staff.

When eating in a restaurant, try to divide meals as much as possible, use public chopsticks, pay attention to observe whether the food has odor and deterioration when eating, and try not to eat aquatic products raw.

If there is a food hygiene problem, it is necessary to protect the problematic food and immediately negotiate with the person in charge of the restaurant. Save invoices and other evidence, and if there are health problems, save relevant evidence such as cases and inspection reports.

If food hygiene problems are found, they can complain and report to the district, county and municipal food hygiene supervision departments in time; In order to avoid food poisoning that can't be identified due to time delay, if food poisoning occurs when eating out, you should immediately complain to the regulatory authorities for timely investigation.

In summer, we should pay attention to the cold storage of cooked food. Usually, the storage time of cooked food at room temperature should be controlled within 2 hours. Frozen food should be heated thoroughly before eating.

Consumers and friends like to cook cold dishes in summer, and fruits and vegetables processed with cold dishes must be cleaned and disinfected. In summer, due to more pests and diseases, the probability of using pesticides in vegetables is relatively increased. Experiments show that soaking for 30 minutes and then rinsing can remove 30% of pesticides in vegetables, and if soaking for 1 minute, it can reduce 80%. But the soaking time should not exceed half an hour, otherwise it will rot easily.

Two drinks

Cold drinks, beverages and other foods are the best-selling foods in summer. Judging from the inspection in recent years, the qualified rate of regular manufacturers' products has reached more than 95%. Therefore, when buying cold drinks and beverages, you must buy the products of regular manufacturers with complete labels and good senses, and never buy the "three noes" products of unlicensed stalls. After replenishing enough water, don't overeat cold drinks and beverages, because high temperature makes most of the internal organs and blood vessels of the human body relax. Eating a lot of cold drinks can cause rapid contraction and even spasm of blood vessels, which can easily lead to abdominal pain, diarrhea and other symptoms.

In summer, the first choice is our traditional green tea or herbal tea made of honeysuckle and chrysanthemum. These drinks have the effects of clearing away heat, promoting fluid production, relieving summer-heat, quenching thirst, clearing away heart fire, inducing diuresis, improving eyesight and refreshing, and also have the functions of anticancer and caries prevention. The most convenient and affordable is the traditional folk mung bean soup. Mung beans are sweet and cool, and rich in protein, phospholipids, carotene, riboflavin, nicotinic acid and so on. Has the effects of invigorating qi, clearing away heat and toxic materials. It not only has good functions of diuresis to relieve summer heat, clearing away heat and toxic materials, strengthening spleen and stopping diarrhea, but also has the function of treating rheumatism and joint pain. Then there is the equally popular sour plum soup. Sour plum tastes light and sour, and has antibacterial effect. It can not only stop diarrhea and thirst, but also restrain body fluids, and also has certain therapeutic effects on summer heat, polydipsia, deficiency heat and thirst, long diarrhea time and bloody stool.

3 Supplementary nutrition

In summer, we should eat more light, soft and digestible food, and eat less greasy, heavy and spicy things, which is called tonic in nutrition. Because light food can play the role of clearing away heat and reducing fire, astringing sweat and rehydrating. It can also stimulate appetite and supplement nutrition.

From the perspective of clearing away heat and nutrition, light foods can be roughly divided into three categories: first, fish, lean meat, eggs, milk and beans rich in protein. At high temperature, protein decomposition and excretion of human tissues increase, so the intake of protein should be increased. The second is light porridge. Eating porridge in summer is different from eating porridge in winter. It is most suitable for eating mung bean porridge, red bean porridge, tea porridge, lily porridge, lotus seed porridge and lotus seed barley porridge. The third is fresh vegetables and fruits rich in various vitamins. In summer, the human body's demand for vitamins is more than L times higher than the ordinary standard. Fresh vegetables and fruits ripe in summer contain a lot of vitamins, such as tomatoes and nectarines, which are called "natural vitamin warehouses", and their vitamin content is also very high. There are other fruits and vegetables, so you can eat more.

Add some bitter food Alkaloids contained in bitter food have pharmacological effects such as relieving summer heat, promoting blood circulation and relaxing blood vessels. Eating bitter foods such as bitter gourd, bitter vegetables, beer, tea, coffee and cocoa in hot weather can not only clear the heart and relieve annoyance, but also stimulate appetite, strengthen the spleen and benefit the stomach.
