1. Common sense of safe use of natural gas

How to use gas safely? People usually call natural gas, liquefied petroleum gas, coal gas and other flammable gases gas.

gas brings a lot of convenience to people's lives, but if it is not used properly, it will also cause disasters. Pay attention to the following points when using gas; 1. Read the operating instructions of gas appliances carefully, and operate and use them in strict accordance with the requirements of the instructions.

2. When using a manually ignited gas cooker, the principle of "fire equals gas" should be adhered to, that is, the fire source should be close to the cooker before opening the gas valve. 3. Always keep the gas appliances in good condition, and repair them in time if air leaks; In case of air leakage during use, you should immediately close the main valve and cut off the air supply.

4. When the gas appliances are in working condition, people should not leave for a long time, so as to prevent the fire from being blown out by the wind or doused by the overflowing water in the pot, resulting in a large amount of gas leakage and fire. 5. The use of gas appliances (such as gas stoves, gas water heaters, etc.), should fully ensure indoor ventilation, keep enough oxygen to prevent gas poisoning.

2. Common sense of safe use of gas

1. In case of accidental gas leakage, never start any electrical equipment, including turning on lights, exhaust fans, range hoods, televisions, radios, making phone calls, etc. Open doors and windows in time for ventilation and report to the gas company promptly.

2. Gas appliances should be qualified products from regular manufacturers, and accidents should not be buried for the sake of being cheap for a while. 3. When installing the gas water heater, we must ask a professional team to carry out standardized installation. When using the water heater, we must maintain good indoor ventilation.

4. When using gas, someone must watch over the stove. Check whether the gas valve is closed before going out and going to bed every day.

5. During indoor decoration, gas facilities should not be moved, gas meters, gas pipes, etc. should not be installed in cabinets, and gas valves should not be sealed. 6. The gas cooker can't be placed directly below the gas meter, and it must be staggered directly below the gas meter by more than 31 cm, so that the gas meter can't be heated and damp.

3. How to write safety tips

Water, electricity and gas are closely related to life, so we must pay attention to safety when using them. We should adopt the "two-minute prevention method" (that is, take one minute to check the water source, gas source, fire source and doors and windows at home before going to bed and before going out) to prevent accidents.

First of all, water safety: we should keep drinking water clean and sanitary, and do not drink raw water or dirty water. The most important thing is to save water, turn off the tap at hand, and adopt the water-saving method of multi-purpose and recycling one water; Secondly, it is safe to use electricity, which must be done as follows: do not pull or connect wires privately, and do not stay and play near poles and cables; Finally, the safety of gas use: minors are strictly forbidden to use liquefied petroleum gas. When adults use gas, they should stay by it until they are finished. After using it, they should turn off the main switch in time. In case of gas leakage, they should immediately open the doors and windows to maintain air circulation.

4. What are the common knowledge of safe use of water heater?

Be sure to pay attention to the matching of power plug and socket, and the contact between them should be close; If the contact between the plug and the socket is loose, the plug will heat up, which will cause a short circuit.

when installing the electric water heater, the weight of the electric water heater should not be borne by only two loose bolts, and a square steel pipe should be installed under the electric water heater to ensure that the water heater will not fall off the wall. It must be filled with water for the first time and then electrified.

the water in the water tank should be replaced regularly, and the water will deteriorate easily if it remains for a long time. For the export open electric water heater, it is not allowed to install valves or any joints beyond the regulations at the outlet, because the outlet (spraying) of the export open electric water heater plays the role of a vent hole; If a valve is installed at the outlet or any connector other than the specified one is connected, it is equivalent to turning an open interface product into a closed one, which will affect the service life and cause damage to the machine.

5. Safety of water, electricity and gas

As the year is approaching, it is inevitable for people to visit relatives and friends when they are busy with New Year's goods or during festivals. Apart from paying attention to traffic safety, fire prevention and theft prevention at home is also a top priority. Here, the safety precautions for water, electricity and gas at home during festivals are emphasized:

1. Precautions for the use of water pipes:

1. Check whether the faucet is slippery or not. To prevent the pipeline from bursting due to water pressure, and to prevent water from flooding Jinshan when there is no one at home.

2. Precautions for the use of electricity:

1. When using electrical appliances, pay attention to check whether the wires of the electrical appliances are damaged and whether the sockets are burnt, and replace the defective parts in time.

2. Try to remove unused electrical appliances from the sockets when going out, such as electric mattresses. Long-term electrification will lead to excessive heat and fire.

3. Gas

1. Prevent the water in the appliance from boiling and causing fire

2. Prevent the water in the appliance from overflowing, causing gas leakage and causing explosion and fire

3. Turn off the valve when going out to prevent fire.

6. How to use gas safely

When using gas, pay attention to ventilation, don't close doors and windows, and do a good job of "opening the kitchen window, closing the stove valve, closing the front valve and closing the kitchen door".

use gas to ignite first, and then turn on the gas. If it is not lit for a while, turn off the switch of the cooker quickly, and avoid venting first and then igniting.

pay attention to adjust the size of flame and damper, so that the combustion flame is blue cone and stable. When in use, people should not stay away from it, so as to avoid the boiling soup overflowing and extinguishing or the flame being blown out by the wind, resulting in air leakage.

after use, pay attention to turn off the switch of the gas stove or water heater, so that people will go out. At the same time, the valve in front of the stove is closed to ensure safety.

if it is not used for a long time, please close the valve in front of the meter. Keep the kitchen ventilated. Because it is cold in winter or air conditioning is turned on in summer, many users tend to close the doors and windows, which will easily lead to a large number of carbon monoxide poisoning caused by insufficient gas combustion. Therefore, users should pay attention to keeping indoor ventilation when using gas.

after using the gas water heater at night, it is necessary to close the gas valve in time to avoid accidents caused by opening the gas valve at night. At the same time, due to the dry climate in winter and the frequent occurrence of fires, users should always check whether there are flammable and explosive articles piled around natural gas appliances and pipelines.

there are two main methods for self-inspection at home: one is smell inspection, that is, always pay attention to whether there is a strong smell near gas facilities. The gas supply department added odorant tetrahydrothiophene to the natural gas, so that when the natural gas leaks, users can smell the odor and prevent accidents.

the second is the brush liquid inspection method, that is, a soft brush is dipped in foaming agents such as soapy water and washing powder solution, and all parts of the home gas pipeline facilities and gas cookers are fully smeared and carefully observed. If bubbles are found, it means that there is air leakage here.

7. How to use the gas water heater safely

1. The gas water heater must be installed outside the bathroom, and an exhaust pipe should be installed according to the national standard, so that the exhaust gas generated by the gas water heater can be discharged to the outside during use, and at the same time, the indoor ventilation must be kept well, otherwise it may lead to carbon monoxide poisoning accidents.

2. When the flue gas water heater is used, natural convection between indoor air and outdoor air should be ensured. 3. The flue gas water heater should be used with caution in windy weather.

if it is found that wind flows backward into the room along the flue, please stop using it. 4. The gas water heater, especially the flue gas water heater, needs regular maintenance, otherwise it will affect the combustion due to long-term use, dust and carbon deposits blocking the heat exchanger, resulting in a significant increase in carbon monoxide in the flue gas, and then a carbon monoxide poisoning accident will occur.

Therefore, it is necessary to entrust professional maintenance personnel to clean the carbon deposit and dust on the heat exchanger every six months to ensure the smooth discharge of flue gas.

8. How to prevent electricity and gas

Electricity prevention: 1. Stay away from high-voltage poles, iron towers and lightning rods in rainy days.

the lightning rod should be intact and tested regularly. 2. When electrical equipment breaks down, don't disassemble it by yourself. Find an electrician with an electrician's operation certificate to repair it.

when the power equipment or high-voltage line fails, you should call the police and ask the power department to handle it. 3. According to the design specifications and operation specifications, ensure the installation quality.

do not use inferior, worn-out and damaged wires and electrical equipment. 4. Electrical equipment must have protective zero connection and protective grounding device.

and check it frequently to ensure its safety and reliability. 5. Configure the equipment and wires according to the safe current carrying capacity of the line, and do not arbitrarily increase the load to prevent short circuit and leakage caused by overcurrent and heat.

when replacing the line fuse, don't arbitrarily increase the specification, and don't replace it with other wires. 6. When repairing electrical equipment and mobile electrical equipment, completely cut off the power, and hang a safety sign "No closing, someone is working" in a conspicuous position.

all devices and lines that have not experienced electricity are considered to have electricity. Capacitive equipment should be discharged first, and movable equipment should be prevented from pulling off the power line.

7. Distribution boxes, switchboards, knives, buttons, sockets, wires, etc. that are frequently contacted in use should be intact. Insulation aging and damage should be replaced in time.

8. machine tool working lamp, portable temporary lighting, to use no more than 36V safe voltage. Gas prevention: 1. Ventilation.

When using gas in the kitchen in winter, never close all the doors and windows because you are afraid of cold. The kitchen must be ventilated and refreshed regularly. Generally, the space in the kitchen is relatively small, so there must be louvers or ventilation fans to ensure that fresh air enters and exhaust waste gas.

2. Air door adjustment method. When you use all kinds of burning appliances, you'd better always observe and check the fire point.

generally, the blue flame is normal, and red and yellow flames are not allowed. Red and yellow fires are usually caused by incomplete combustion, which not only stimulates gas, but also wastes energy.

In addition, families with gas-fired water heaters should try their best not to use the water heater continuously for several people to take a bath for a long time. Because the water heater is a high-oxygen burning appliance, a large amount of carbon dioxide generated after combustion is not easy to be discharged quickly indoors, which in turn causes the combustion condition of hot water equipment to decline and the vicious circle is prone to gas poisoning.

3. Leak detection method. If you feel fishy smell or odor in the kitchen, feel dizzy or flush, you should first suspect that your own gas or liquefied gas has leaked and caused mild poisoning.

at this time, be sure to check whether there is any gas leakage.

9. How to use gas safely

1. What should I pay attention to before using gas? When using gas, you must pay attention to whether there is odor, and fire it when it is confirmed that there is no air leakage, and pay attention to good ventilation.

second, what should I pay attention to when using gas cylinders? 1. Please pay attention to the inspection period of cylinders and attach the inspection standard. 2. Please keep the cylinder upright and avoid violent vibration.

3, placed in a well-ventilated place to avoid the sun. 4. Do not use the cylinder upside down.

5. Do not put anything on the cylinder to avoid ignition. Third, how to find out whether the gas pipeline leaks? When it is suspected that the gas pipe (pipeline) at home is leaking, you should not use matches or lighters for ignition test, but should check whether there is leakage with soap bubbles.

4. where should the gas water heater be installed? It should be installed in a well-ventilated outdoor place to avoid the accident of carbon monoxide poisoning. 5. What is the phenomenon that gas fireworks show red flame? What is the danger? What should be done? The gas flame is normally light blue, and if it is found to be red, it means incomplete combustion.

there is a risk of carbon monoxide poisoning, so please ask a gas professional to repair and adjust the stove immediately. 6. How do you know about the gas leak? 1, sense of smell-household gas is mixed with odorant, which will have its own taste when it leaks.

2. Vision-gas leakage will cause foggy white smoke in the air. 3, hearing-there will be a "hissing" sound.

4. Touch-when the hand approaches the leaked hole, it will feel cool. Seven, how to deal with gas leakage? 1, immediately turn off the gas switch.

2. Never turn on or off any electrical switch. 3. Gently open all doors and windows and quickly escape from the outdoor.

4. Call the police. 8. Will gas kill people? 1, the gas itself is not toxic, but it has anesthesia and suffocation, which reduces the biological reaction ability.

2. Improper use of gas will produce a large amount of carbon monoxide, which is easy to combine with heme in blood, resulting in anoxia (carbon monoxide poisoning, leading to death). Nine, the use of gas and air is insufficient, and carbon monoxide poisoning should be done? 1. Turn off the gas switch.

2. Open the doors and windows for ventilation. 3. Provide fresh air for the injured.

4. Unbind and clear the respiratory tract. 5, as the case may require artificial respiration or cardiopulmonary abdominal compression.

6. Don't turn on or off any power switch before the gas odor dissipates, so as to avoid sparks and fire. What are the symptoms of carbon monoxide poisoning? 1, will have a headache, dizziness, nausea, vomiting.

2. There will be a strong sense of collapse, accelerated breathing and pulse, blurred consciousness, and the body cannot move autonomously. 3, flushing, loss of consciousness, respiratory arrest, convulsions, leading to cardiac arrest and death.

12. what should I do if the gas pipeline is accidentally cut off due to sewage pipeline construction? If the gas pipeline is accidentally cut off due to sewage pipeline construction, please turn off the fire source at home immediately. If the pipeline catches fire, do not put out the fire rashly, draw a warning line and call the police as soon as possible. Residents or pedestrians near the pipeline cut-off place should avoid smoking, or start the steam engine, locomotive engine and various power switches to avoid explosion or combustion. Personnel should stay away from the scene as far as possible. Before the handlers arrive at the scene, please surround the scene with ropes and write slogans such as gas leakage to remind people and people passing by. .
