Safety is related to our life and our happiness. There are too many hidden dangers in this world. For example, at school, don't run around fighting on the stairs. There is a lot of water in the corridor on rainy days, which makes it easy to slip. And don't bring some knives into school, let alone lighters. When resting in the corridor, don't lean out of the railing, let alone climb up. Don't throw things downstairs from the corridor. Don't run, chase and play games in the classroom.
The security risks outside the school are the same, for example, when crossing the road, you must pay attention. Don't walk with strangers at will. Don't eat snacks that haven't passed the safety test. Don't go to entertainment places such as Internet cafes.
In addition to these off-campus and on-campus safety, there is also home safety, such as not touching wires, which is easy to get an electric shock. Sometimes mom and dad forget to turn off the fire when cooking, so be sure to remind them in time. Also, don't touch those stoves, it's easy to burn. Don't play with boiling water to avoid scalding the panel.
Prevention of security risks starts from the side and starts from everyone!
How to guard against the hidden dangers around you? Recently, there have been many stories of falling from high altitude. Families with children should be careful not to leave their children alone at home, and those with bay windows should be equipped with guardrails. Next to the community is the canal. Go for a walk by the river in the morning and evening, pay attention to safety and prevent drowning. At present, it is generally the elderly who pick up and drop off children. When the car passes the road in front of the kindergarten, we must pay attention to avoiding the elderly and children ... There are often various unsafe factors in the inconspicuous places. During this period, the "Five Tigers of Peace", composed of five students from Class 4 of Pujia Primary School in Hangzhou, carried out a meaningful social practice: investigating the hidden dangers around them and publicizing relevant safety knowledge to nearby residents.
"Household gas leakage, electric shock, falling from high altitude, forgetting to turn off the electrical appliances lead to fire ..." "Five Tiger Generals of Peace" first summed up 10 major safety hazards in daily life through past experience and careful observation. Then, the Five Tigers will focus on Wanjia Garden in the community where the school is located, carefully observe the surrounding roads and buildings, draw a map of safe homes, and mark the places where there may be potential safety hazards with red pens. On the rest day, while promoting safety knowledge, students distributed their own maps of safe homes to nearby residents, which were well received by everyone. "There are pictures and truth, your works are true, the propaganda is convincing, and my children like it very much!" Aunt Wang who lives in the community said.
"We traveled to every corner of the community, carefully observed places with unsafe factors, and tried to draw a map of safe homes. Although sweat dripped from our faces, we were still happy. I hope that through our efforts, everyone will increase their safety awareness in their lives and try to' prevent problems before they happen'. " The five tigers will say. The activity was also affirmed by parents. Everyone thinks that such activities not only improve students' safety awareness, but also exercise teamwork and integration into society.
There are hidden dangers around you, so we should take precautions before they happen. So I decided to check all the hidden dangers at home with my father.
Let's go to the master bedroom first. I took a fancy to it. Hey, why don't you unplug the TV? I think: the power plug is not pulled all the year round, which is easy to cause fire. Especially in thunderstorm weather, the wires will be short-circuited. Thinking of this, I immediately went to the front of the TV and unplugged the power. Dad said to me, "observation is not bad." Come on, look, that high-temperature iron is placed in a place where people can easily touch it, which is very easy to burn people. "So, dad put the iron in the safe. Hehe, the hidden dangers of family safety have been reduced again.
Then we came to the bathroom. "oh! The ground was wet and slippery, and I almost fell. " I complain, I say; "Dad, you see, the outside of the bathtub is wet and slippery, which makes people fall easily and is also a safety hazard. We quickly brought anti-skid pads. Haha, that's great. I will never wrestle in the bathroom again. Dad said, "It's time for us to have a look in the kitchen. "
We went to the kitchen and examined every corner of the kitchen carefully. Suddenly, my father seems to have found something, and his expression is extremely serious. Dad said to me, "Look at that shelf, which is full of kitchen supplies, including scissors, kitchen knives, small shelves and other items." Dad paused and then said, "Scissors and kitchen knives shouldn't be hanging on this shelf. A little careless, if you fall, you may hurt people. " After listening to my father's words, I immediately put the scissors and kitchen knife on the knife rest.
Finding hidden dangers around us will bring us unnecessary harm and be very dangerous. But there are many hidden dangers in life.
The most dangerous safety hazard in my home is that there is a wire stuck in the air in the room where my brother and I study, and that wire is connected to my desk lamp. So when you walk through that place, you have to lift your legs and cross it. It's easy to trip, and if the glass breaks, it will hurt people.
On Wednesday, I walked through this passage, but I fell down. I tried to hold the ground with my hands, but I grabbed the wire and the desk lamp fell down. Bang, the light bulb burst and the glass flew all over the floor, so I had to sweep it with a broom.
After a while, I heard my brother shout "Wow". I quickly asked, "What's the matter?" "My toe was stabbed!" "I see a thorn!" I gave him the nail clipper and he gave it a poke. It turned out to be a small piece of bloody glass, which startled us.
Although everyone says that we should eliminate potential safety hazards, few people do it, so I think we should eliminate potential safety hazards.
For reference, adopt.
Discover the hidden dangers around you. Life is beautiful, but life is also fragile, so safety is the foundation of our life. Let's clear away the hidden dangers around us together! Safety is more important than Mount Tai, and the hidden dangers around us should start from traffic safety. The nearest to us are the rows of "office workers" cars or electric cars in the school, because the owners are as eager to go to work and work as we are. Sometimes, when you are in a hurry, there will be unexpected accidents.
Take me for example, because I got up late that morning and left in a hurry, just keeping my head down. I didn't expect an aunt to rush to work like me, riding an electric car and running fast, but I didn't see her riding an electric car and she didn't see me running forward. At that moment, we met unexpectedly. Although the injury was not so serious, it sounded the alarm for me and my mother. Here, I also want to solemnly remind everyone that if you don't pay attention to the hidden dangers of traffic safety around you, a small loophole will make you fall into the trap of traffic safety if you are not careful! In addition to the hidden dangers of driving vehicles, vehicles parked on the roadside are also hidden dangers. When you walk on the side of the road or ride an electric bicycle, you should pay attention to these vehicles parked on the side of the road, because they may open the door at the moment you pass, and an accident will happen at the moment you pass inadvertently. An uncle around me once encountered such a thing. Not long ago, during the rush hour, my uncle was riding an electric car leisurely on his way to work. When he passed a car, the car suddenly opened the door. The uncle was badly injured by this sudden accident and has not recovered yet. Students, all kinds of examples around us let us know that safety is more important than everything, and security risks are everywhere. Only by learning to remove hidden dangers and accidents around you will there be fewer and fewer "traps". As long as we work together in Qi Xin and Qi Xin, we can put the safety around us first!

How to prevent potential safety hazards in employment In the daily production process or social activities, there will be problems, defects, failures, signs, hidden dangers and other unsafe factors due to human factors, changes in materials and environmental influences. If it is not found, inquired and eliminated, it will disturb and affect the normal production process or social activities. Some of these unsafe factors are defects and deficiencies. As long as the defects are eliminated after inspection, the problem is solved, and the conditions for stimulating potential (such as kinetic energy, potential energy, chemical energy, thermal energy, etc.) are solved. ) will not be generated. There are also conditions to generate excitation potential, which will form a hidden danger of accidents. Failure to rectify or take effective safety measures can easily lead to accidents.
The so-called definition refers to the judgment, determination or identification of the boundary. [1] In the daily production process or social activities, due to human factors (such as management ability, system implementation, operational skills, psychological state, knowledge level, physiological function, etc. ), changes in things (such as aging and corrosion of equipment and electrical appliances, removal and displacement of safety protection facilities and non-connection with construction progress), and environmental impacts (such as pollution, wind erosion, exposure, etc.). Some of these unsafe factors are defects and deficiencies. As long as the defects are eliminated after inspection, the problem is solved, and the conditions for stimulating potential (such as kinetic energy, potential energy, chemical energy, thermal energy, etc.) are solved. ) will not be generated. There are also conditions to generate excitation potential, which will form a hidden danger of accidents. Failure to rectify or take effective safety measures can easily lead to accidents.
Therefore, by "defining" the conditions that have no excitation potential, we can diagnose or identify whether there are hidden dangers of accidents.

" After listening to my father's words, I immediately put the scissors and kitchen knife on the knife rest.
Finally, we came to the study, and I soon discovered the hidden trouble of the study: there were several boxes on the cupboard, and the top box was "half exposed" outside. I think: the box will slide down at any time, so I must stop the safety accident. I told my father what I thought, and my father immediately moved the chair and pushed the box in. "Hoo," I breathed a sigh of relief. At this time, my father turned to me and said, "Your hot water bottle is already hot. Please unplug it. If it is hot for a long time, it will easily lead to a fire accident. " I immediately unplugged the plug and thought: I really need to check the hidden dangers of family safety.
During the winter vacation, my biggest gain was that I learned to fry salted peanuts.
It was Saturday, and my mother, who had worked for a week, must have worked very hard. She finally has a weekend, so she should have a good rest. So, I said to my mother, "I'll cook today's food, just fry salted peanuts!" " "Mother said," just try it! "
I put a spoonful of salt into half a bowl of water and mix it evenly with chopsticks to melt the salt in the water. I put the prepared salt water aside. Put a dish of peanuts in the pot, then put the pot on the liquefied gas stove and turn on the electronic switch. Suddenly, a blue fire emerged from the small hole and kept jumping around at the bottom of the pot. I fried it for a while. Oh, no, some peanuts are smoking. They are going to burn. In desperation, I remembered that my mother lit a small fire every time she fried peanuts. How can I light such a big fire? I immediately turned down the fire. I fried it a few more times and thought: Is it time to add salt? I tasted a peanut and didn't feel very good. After a while, I tasted another one and thought it was not yet time. In this way, I fried and tasted it, and I couldn't tell whether it was raw or cooked. All right, let's get help. So, I called my mother, and her mother smiled and said, "You are too impatient to fry salted peanuts. Patiently wait for the peanuts to turn red and yellow, and then put salt water in. " So, I started frying again and slowly found that peanuts gradually turned red and yellow. I tasted another one. Wow! It smells good. I poured salt water into the pot. 1 "Zi La", the pot was covered with a layer of white fog. I started cooking again. After a while, the red peanut put on a silver coat. I think: peanuts must be done well. I put peanuts on the plate.
At this moment, my mother came over. My mother tasted my fried peanuts and said, "It's delicious for the first time, not bad, not bad." I also tasted one. Peanuts are crisp, fragrant and salty. It's delicious. My first fried salted peanuts succeeded!
