(6) If someone is found to have been electrocuted, correct rescue measures must be taken immediately.

3. Equipment operation safety knowledge

(1) Electrical equipment, devices and lines that have malfunctioned should not be continued to be used to avoid the expansion of the accident and must be repaired in time.

(2) The operation must be carried out in strict accordance with the equipment operating procedures. When turning on the power, the isolating switch must be closed first, and then the load switch; when the power is disconnected, the load switch must be cut off first, and then the isolating switch.

(3) When it is necessary to cut off the power supply in the fault area, the scope of the power outage should be minimized. If there is a shunt switch, try to cut off the shunt switch in the fault area and try to avoid overstepping the power supply.

(4) Electrical equipment generally cannot be affected by moisture, and measures must be taken to prevent rain, snow, and water vapor from invading. Electrical equipment generates heat when running, so good ventilation conditions must be maintained, and some fire prevention measures must be taken. All live equipment, especially high-voltage electrical equipment, must have measures to prevent small animals from entering and causing short-circuit accidents.

(5) The metal enclosures of all electrical equipment should have reliable protective grounding measures. All electrical equipment that may be struck by lightning must be equipped with lightning protection facilities.

4. What are the safety precautions during maintenance?

(1) Pay attention to ventilation and supervision. Before entering the drum and container, the manholes and holes on the drum and container must be removed. All hand holes on the header should be opened to allow air convection for a certain period of time and sufficient ventilation.

When entering the drum or container for inspection, someone must be supervised outside the container. Ventilation must also be carried out before entering the flue or combustion chamber for inspection.

(2) Pay attention to electrical safety. When using electric lamps for lighting when inspecting the boiler drum and humid flue, the lighting voltage should not exceed 24 V; in relatively dry flues, appropriate safety measures must be taken , a lighting voltage no higher than 36 V can be used. When entering the container for inspection, a low-voltage explosion-proof lamp with a voltage not exceeding 12V or 24V should be used.

When the power supply voltage of inspection instruments and repair tools exceeds 36 V, well-insulated soft wires and reliable grounding wires must be used. It is strictly prohibited to use open flame lighting in boilers and containers.

(3) It is prohibited to disassemble and assemble connecting parts under pressure when inspecting boilers and pressure vessels. If it is necessary to remove or tighten the fasteners of pressure-bearing parts, all pressure must be released before proceeding. Do not remove or tighten bolts or other fasteners when there is pressure inside the device to prevent accidents. (4) It is forbidden to use air pressure test instead of water pressure test on your own. The pressure test of boiler pressure vessels generally uses water as the pressurized medium, and gas cannot be used as the pressurized medium, otherwise it will be very dangerous.

6. Little knowledge about safety

Traffic safety knowledge for primary school students: When the green light of the crosswalk signal is on, pedestrians are allowed to pass the crosswalk; when the green light is flashing, pedestrians are not allowed to enter the crosswalk, but they have already entered the crosswalk. can continue to pass; when the red light is on, pedestrians are not allowed to enter the crosswalk.

Traffic Safety Clap Song You clap one, I clap one, traffic safety is the first, you clap two, I clap two, traffic lights must be seen clearly, you clap three, I clap three, * ** To stay safe at a red light, you shoot four, I shoot four. If the vehicle is driving, drive to the right, you shoot five, I shoot five. Be careful when turning. You shoot six, I shoot six. Don’t have people on the bicycle. You shoot Seven, I shoot seven, don’t play while walking. You shoot eight, I shoot eight. Life is the first priority. You shoot nine, I shoot nine. Obeying the law is the most important. You shoot ten, I shoot ten, be a What should civilized citizens pay attention to when crossing the road? l. Follow the instructions of the traffic police and follow the instructions of "go on green light and stop on red light". 2. Follow the pedestrian crossing lines; in sections with overpasses and underpasses, you should consciously cross overpasses and underpasses.

3. Walk in a straight line and do not go in a roundabout way; when there is no crosswalk, you should first look to the left, then to the right, and only cross the road after confirming that no motor vehicles are passing. 4. Do not climb over the safety guardrails and isolation piers in the center of the road.

5. Do not cross the road suddenly, especially if there are acquaintances or friends calling from across the road, or the bus you want to take has already pulled into the stop, you must not act rashly to avoid accidents. What are the most dangerous situations when walking? (1) Crossing the road can easily lead to danger.

(2) Walking sideways in groups on non-pavements is the most likely to cause traffic accidents. (3) After the peak hours of commuting and getting off work, there are few vehicles on the road, because the lack of cars and people on the road numbs the mind.

Paralysis plus paralysis equals danger. (4) Do two things while walking. Read a book while walking, or think about a problem while walking, or chat while walking, or play while walking... If you do this, the car may not hit you, but you will hit the car yourself, so it is also very dangerous. .

Things to note when taking a motor vehicle: 1. Wait in line, get on in a first-come, first-served order, and avoid crowding. When getting on or off, you should wait until the car has stopped, get off first and then get on, without fighting.

3. Do not stick your head or hands out of the window, and do not throw debris out of the car window. 4. Sit firmly and support yourself. When there is no seat, keep your feet apart naturally, stand sideways, and hold the handrails tightly to avoid falling and injury when the vehicle brakes in an emergency.

5. When riding in a car, you should fasten your seat belt when riding in the front row. How to recognize traffic lights? There are two types of traffic lights. One is a three-color red, yellow, and green signal light used to direct vehicles. It is set in a conspicuous place at an intersection and is called a vehicle traffic light; the other is used to direct pedestrians to cross the road. The red and green signal lights are installed at both ends of the crosswalk and are called crosswalk lights.

my country's traffic regulations also stipulate the traffic control lights: 1) When the green light is on, vehicles and pedestrians are allowed to pass, but turning vehicles are not allowed to obstruct the passage of straight vehicles and pedestrians. 2) When the yellow light is on, vehicles and pedestrians are not allowed to pass, but vehicles that have crossed the stop line and pedestrians that have entered the crosswalk can continue to pass.

3) When the red light is on, vehicles and pedestrians are not allowed to pass. 4) When the green arrow light is on, vehicles are allowed to pass in the direction indicated by the arrow.

5) When the yellow light is flashing, vehicles and pedestrians can pass under the principle of ensuring safety. 4. Cycling safety knowledge: my country is known as the “Kingdom of Bicycles” and has the largest number of bicycles in the world.

However, bicycles have a simple structure, fall over when touched, and have poor stability, so they are the weakest means of transportation. Among traffic casualty accidents, non-motor vehicles (mainly bicycles) rank first in the number of injuries and second in the number of casualties.

In our country, children must be 12 years old or older before they can ride a bicycle on the road, and they must abide by traffic rules and ride in the slow lane. When the green light is on, pedestrians are allowed to pass; when the yellow light is on, pedestrians are not allowed to pass, but pedestrians who have entered the sidewalk can continue to pass; when the red light is on, pedestrians are not allowed to pass; when the yellow light is flashing, pedestrians are not allowed to pass Passage must be conducted under the principle of ensuring safety.

Pedestrians must abide by the regulations. Pedestrians must walk on the sidewalk and walk to the right when there is no sidewalk; when crossing the road, you must use a crosswalk; when passing a crosswalk controlled by a traffic signal, you must obey the signal regulations; when passing a crosswalk without traffic signal control On the sidewalk, you should look left and right, pay attention to the traffic, and you are not allowed to chase or run; if there is no crosswalk, you must go straight through, and you are not allowed to cross suddenly when a vehicle approaches; if there is a pedestrian overpass or underpass, you must use the overpass or underpass; it is not allowed Climb the guardrails and isolation fences on the side of the road and in the middle of the road. It is not allowed to push cars, chase cars, forcibly block cars, or throw objects at cars on the road. What safety precautions should you pay attention to when riding a bicycle? Compared with walking, riding a bicycle has more unsafe factors. The safety matters that need to be paid attention to are as follows: 1. Regularly inspect the bicycle to keep it in good condition.

It is especially important to check whether the brakes and bells are sensitive and normal. 2. The size of the bicycle must be appropriate, and children’s toy bicycles should not be ridden on the street.

Don’t let people ride large bikes. 3. Do not learn to ride a bicycle on the road; children under twelve years old should not ride a bicycle on the street.

4. When riding a bicycle, you must drive on the right side of the non-motorized lane and do not drive in the opposite direction; do not rush and turn sharply when turning. You must slow down in advance, see the surrounding situation clearly, and give clear gestures before proceeding. Turn. 5. When passing through an intersection, drive slowly and pay attention to pedestrians and vehicles; do not run through red lights, stop and wait when encountering a red light, and continue moving forward when the light turns green.

6. When riding a bicycle, do not let go of the handlebars with both hands, do not ride with many people together, do not support each other, do not chase each other, or fight. 7. Do not climb or support motor vehicles while riding, do not carry overweight objects, do not carry people with you on the bike, and do not wear headphones to listen to the radio while riding.

Safety knowledge songs for primary school students (1) When encountering gangsters, remember the phone number of the gangster and the police clearly, and deal with it with dexterity and dexterity. The gangster is captured and people will be happy; Rivers in private are not safe, so beware of dizziness and convulsions. A river is flooded with water. If you can't finish drinking, you will go to hell in your youth; be careful when receiving hot water, you may overturn the pot or bottle and burn yourself. Spend money too late and feel sad. Heal the uneven skin; When the river rises, don't overdo it. Trying to show off your strength will lead to disaster. It is safe to walk in detours, and everyone will be happy when the weather clears up after the rain; when passing through the courtyard, do not tease the dog, call an adult to drive the dog away, and do not try to be clever, as there is a danger of being bitten by a dog; on a hot day, walk long distances, and remember not to pour boiling water drink.

7. Safety knowledge

Spring safety precautions for residents: How to prevent gas poisoning. Gas fuels used in households, such as coal gas, liquefied petroleum gas, biogas, etc., are all toxic gases and contain Carbon monoxide and other substances harmful to human body.

Once the human body inhales high concentrations of these gases, it will collapse. If rescue is not carried out in time, it will cause death. The key to preventing gas poisoning is to eliminate the leakage of these gaseous fuels used in the home.

It should be emphasized that when using gaseous fuel, the environment must be well ventilated. In this way, in the event of a small leakage of gaseous fuel, there will still be sufficient oxygen for people to breathe, preventing serious poisoning accidents.

Families using coal stoves in rural areas should also prevent coal stoves from being left in the bedroom overnight and causing poisoning accidents. If the coal stove is placed in the kitchen or living room, do not close the doors and windows tightly when sleeping. It is best to place the coal stove outdoors at night or extinguish it to eliminate hidden dangers.

Especially in winter, never sleep next to a coal stove just to stay warm at night. Otherwise, it will be too late to cause tragedy.

How to rescue gas poisoning If someone is found to be poisoned by gas, do not press any electrical switch to avoid sparks causing an explosion. You should first open the windows to ventilate the room, then quickly move the poisoned person outside to a ventilated area, unbutton his collar and let him breathe fresh air.

Be careful not to let it catch cold, otherwise, its body temperature may drop and its heartbeat may stop. If the poisoned person can drink water, you can feed him hot sugar and tea, and pay attention to keeping warm. Do not apply cold towels to the head, let alone pour cold water.

When the poisoned person has difficulty breathing or has just stopped breathing, he should immediately perform artificial respiration or external chest cardiac surgery. At the same time, he should call the medical rescue unit or ask neighbors for help and send the patient to the hospital for treatment. . Of course, while rescuing people, we must find out the cause of the gas leak as soon as possible and plug it to prevent others from being poisoned and harmed again.

How to use hot pot safely When purchasing hot pot, users should pay attention to product quality and avoid purchasing untested inferior products. When a problem is found, do not disassemble or modify it at will. It should be sent to the original manufacturer and maintenance center for repair.

Before using hot pot, you must first familiarize yourself with the usage and safety knowledge. If you are using a charcoal hot pot, place a plate under the hot pot and put a little less water or other insulating materials to prevent the high temperature from damaging the tabletop or even causing a fire.

If you are using a liquefied gas (gas) hot pot, you should prevent gas leakage when using it. After igniting the fire, always pay attention to the burning condition and adjust the flame to prevent the soup from boiling over, extinguishing the fire and running out of gas, causing gas poisoning or fire and explosion accidents. When not in use, cut off the power supply. The power cord should be connected to the pot first and then the power supply (cut off the power supply and vice versa). Do not allow food to overflow. If it does, cut off the power supply first and then wipe it clean. After using the hot pot, cut off the power supply, clean and dry the pot, and store it in a dry and ventilated place.

After using up the electric or gas hot pot, be sure to cut off the power or gas source, and dispose of charcoal ash safely in the charcoal hot pot. The remaining alcohol in the alcohol hot pot should be poured into a container and placed in a safe place to prevent fire caused by children playing.

Prevent fires caused by electric blankets. The elderly and infirm people like to use electric blankets when the cold snap comes. However, if the electric blanket is continuously powered on for too long, without a constant temperature safety device, it is easy to cause a fire accident. In addition, if the electric blanket breaks due to long-term rubbing, it can also cause a fire.

To prevent electric blankets from causing fires, you must first pay attention to insulation and prevent short circuits. If the electric blanket is damaged, do not dismantle or repair it at will. Please ask an electrician to inspect and repair it.

In order to prevent you from accidentally forgetting to cut off the power supply, you can use a three-way plug, plug in a light on one end, and connect an electric blanket on the other. In this way, when the lights are turned on at night, the electric blanket will be energized to heat up, and the electric blanket will also be turned off when sleeping. power outage. It is best not to use electric blankets when children sleep to prevent bedwetting and electric shock.

Electric blankets should be kept away from folding and moisture. When using an electric blanket that has not been used for a long time, carefully check whether there is any leakage.

Once the electric blanket catches fire, first cut off the power supply and then try to put out the fire. □Reprinted by Yan Jianquan = =.
