Matters needing attention in the use of gas tank

Question 1: What should I pay attention to when using gas tanks? A, the correct procedure for the safe use of gas:

(1) When using gas, the operating rules of "fire equals gas" shall be strictly observed;

(2) first ignite, put it into the furnace, and start the gas switch from small to large until the gas burns completely;

(3) When igniting and conveying gas, pay attention to that the flame is instantly ejected from the fire, and the face cannot be close to the furnace mouth when the gas is ignited;

(4) When the fire goes out, the master brake should be completely closed;

(5) Someone should take care of the gas during use, and pay attention to check whether the pipeline switch is dead. After work, someone will check whether the stove is completely extinguished before leaving.

2. Precautions for using gas tank 1, whether the sealing ring on the checker falls off or not when changing the tank, and also pay attention to the reverse connection of the pressure reducer and the angle valve (i.e. counterclockwise rotation), and remember not to reverse screw when installing; After installation, shake the pressure reducer body by hand. If it swings, it needs to be reinstalled. 2. There must be a distance of 1 to 1.5m between the gas tank and the cooker. The place where gas tanks are used should be well ventilated, and coal stoves cannot be stored or used at the same time; 3. Learn to leak. Brush the joints of hoses, joints, pressure reducing valves and hoses with soapy water frequently to check for air leakage. 4. learn to ignite. The ignition step is very important. If there is no ignition for more than two times, you should stop hitting the fire site immediately, because there will be gas leakage. You should stop the car for more than two minutes until the leaked gas dissipates, and then try the second ignition. Do not turn on the exhaust fan. If the exhaust fan is turned on at this time, the high-concentration mixed gas in the air may explode when it is ignited. 5. Learn to adjust the wind direction. In the process of using gas, if it is found that the pots and pans are blackened, or the fire is extinguished, the flame is red or yellow. At this time, the ratio of gas to air may be inappropriate, so it is necessary to adjust the damper to normal to make the flame blue; 6. In case of fire accident, learn to handle it calmly. Immediately close the angle valve of the gas tank with a soaked towel and move the gas tank to an outdoor open place to prevent explosion; In addition, it is not allowed to turn on the range hood when it is on fire, and the electrical equipment near the gas tank will be cut off immediately; 7. The gas tank can't be disassembled without permission, nor can it be placed upside down. As for heating the water tank by pouring hot water, it is absolutely not desirable; Strong sunlight can also lead to gas tank explosion accidents; The residual liquid in the gas tank shall not be dumped indiscriminately, nor shall it be repaired without permission. If the gas tank leaks, it should be immediately sent back to the point of sale for replacement; 8. Pressure reducing valves and hoses should be purchased from regular products produced by qualified manufacturers. The service life of pressure reducing valve is five years, and the service life of rubber hose sealing ring is three years. Check whether the gas tank parts are aging, replace them with new parts as long as they are aging, and never engage in it casually; 9, canteen should designate a person to use gas tanks, and is responsible for the daily management and maintenance of gas tanks, others are not allowed to use.

Question 2: How to use the gas tank safely and what matters should be paid attention to? Safety operation rules for gas stoves.

A, gas stoves, gas tanks, personnel management, check the usage every day.

Second, make all preparations before use.

Third, when turning on the gas every day, carefully check whether there is air leakage and whether the cutting parts of each door are safe and reliable. When replacing the gas tank, the connector must be connected correctly.

Fourth, ensure that the stove equipment is clean and hygienic.

Five, the operator is familiar with the operating equipment and environmental facilities, before operation training.

Six, cooking operators in front of the gas stove to clean clothes, shoes and hats, in the process of operation and use should pay attention to safety, carefully heated food oil escape and burn.

Seven, equipment abnormal timely report to the leadership, looking for professional maintenance.

Eight, after using the gas holder equipment every day, close the main door of the gas holder, check whether everything is closed in good condition, confirm that there is no abnormal situation such as leakage, and lock the gas holder room.

When cleaning the gas stove equipment, cut off the gas source and power supply completely.

Gas canister

Nowadays, liquefied gas is often used in family life, and the commonly known gas tank is a container for loading liquefied gas.

"Gas tank" is a steel mobile pressure vessel, which is in danger of explosion. Its wall thickness is only about 2.5 mm (the wall thickness of the new cylinder is calibrated at the factory), which is very thin. It is always under pressure from the internal media. In normal use, the internal pressure (pressure) is 0.5 ~1.2 MPa (5 ~12 kgf/cm2).

In the process of long-term filling, transportation and use, "gas tank" is damaged by collision, exposure and medium corrosion, which will produce fatigue cracks, pits, deformation, corrosion thinning and other defects, which is the direct cause of explosion accidents. Have you ever seen a gas tank explode?

The explosion of the "gas tank" will cause two injuries instantly. At first, the tank will explode physically, and the liquefied petroleum gas will instantly expand 250 ~ 300 times to become a gas state, producing a shock wave, just like a mine explosion. When the concentration in the air drops to 3 ~ 1 1%, a chemical explosion will occur, and the whole gas space will explode and burn, resulting in huge shock waves, which will hurt lives, burn property, destroy buildings and bring about secondary disasters. If people inhale this explosive gas, it will burn the respiratory tract and lung tissue, which is extremely terrible.

In order to protect people's lives, the Regulations on Safety Supervision of Special Equipment promulgated by the State Council listed LPG cylinders as legal supervision equipment. "Fuel tank" is not a permanent and durable product. Through the analysis of a large number of accident cases and scientific experiments, professional technicians have determined that the safe service life of "gas holder" is only 15 years. During this period, regular inspection should be conducted every four years to find out the existing defects. This is the safety guarantee for you and your family, and it is also stipulated in the Regulations on Safety and Technical Supervision of Gas Tanks.

At present, the price of liquefied petroleum gas cylinders in the market is about 100 yuan, less than a shirt. Don't be stingy and reluctant to update. Stopping the service is a disaster at home. Let me remind you again that you should go to a fixed store to buy a "gas tank", not to the free market, where there are many fake and shoddy goods.

Don't sell your obsolete cylinders as ordinary scrap iron, and don't dispose of them yourself, which is prone to accidents. Send the gas cylinder to the local quality and technical supervision bureau or boiler and pressure vessel inspection office for destructive treatment, otherwise it will fall into the hands of others, and may enter the market after renovation and endanger others.

When you are in doubt about the safety of "gas cylinders", please consult the Bureau of Quality and Technical Supervision in charge of gas cylinder supervision.

Question 3: How to use the gas tank and how to use it correctly? Operating requirements and precautions for using gas tanks

Question 5: How to use the gas tank and how to use it correctly? As a fuel that has been used for so long, the safety factor of the gas tank is still quite high, not to mention that you have installed a safety valve, so don't worry too much. The probability of gas tank explosion in normal use is much lower than that of collision.

Question 6: Precautions for the use of gas stoves What are the main precautions for gas stoves?

1: The gas source used should be consistent with that indicated on the gas stove.

2. Avoid using baffles to cover the flame, and do not place flammable materials around the gas stove.

The gas stove should be installed in a well-ventilated place, not in a place where strong wind blows directly.

4. In case of air leakage, immediately turn off the gas switch, open the doors and windows for ventilation, don't switch the electrical appliances for ignition, and plug in the power plug. 5. Do not touch the burner, stove, stove surface, etc. Use your hands during use or just after flameout to avoid burns.

6. Don't connect the gas pipe with PVC pipe, because it will melt when heated, so use oil-resistant rubber pipe. If there are cracks or joints are easy to loosen, it will lead to air leakage. Do not use it and replace it immediately. During installation, it is forbidden to cross or touch the surface of the stove.

7: When the fire is turned into a small fire, there is no open fire in the outer ring fire hole or the small fire can be turned into a big fire after ten seconds to prevent backfire and damage to panels and other components.

8: Are flammable materials piled up around the gas stove?

9. Check whether there is any air leakage in the gas stove pipeline and handle it in time. Use a brush to apply hot soapy water to all the joints of the gas stove pipeline. If bubbles are found, they are leaking parts and must be replaced immediately or repaired by the branch maintenance department.

10: Is there good ventilation around the gas stove?

1 1: Check whether the flame is normal or abnormal during use.

12: Clean the inner and outer gear ring covers, nozzles and burner holes regularly to prevent dirt from blocking the aperture, and do not damage the aperture when cleaning.

13: To keep the gas stove clean daily, you can wipe it with a wet pad and then smooth it with a dry cotton cloth. It is forbidden to use strong detergent or gasoline for cleaning.

Question 7: Precautions for gas poisoning at home mainly refer to carbon monoxide poisoning, liquefied petroleum gas, pipeline gas and natural gas poisoning. The former is more common in winter when coal stoves are used for heating, doors and windows are closed, and the flue gas is not good, while the latter is more common in liquefied gas stoves or gas pipelines. Gas is easy to combine with hemoglobin in human body. When gas poisoning occurs, patients will initially feel headache, dizziness, nausea, vomiting and weakness. When he realizes poisoning, he often struggles to get out of bed and open the door and open the window, but usually only a few people can open the door. Most patients have convulsions and coma quickly, and their cheeks, chest skin and lips are cherry red. If not treated in time, they will soon die of respiratory depression. Gas poisoning depends on the concentration of carbon monoxide in inhaled air and the duration of poisoning. When the volume of indoor carbon monoxide reaches 0.06%, people will have dizziness, headache, nausea, vomiting, limb weakness and other symptoms. When it exceeds 0. 1%, people will fall asleep and then coma as long as they inhale for half an hour; When it reaches 0.4%, people will die after inhaling 1 hour. There are usually three types: light 1. The poisoning time is short, and the carboxyhemoglobin in blood is 10% ~ 20%. It manifests as early symptoms of poisoning, such as headache, dizziness, palpitation, nausea, vomiting, limb weakness, and even fainting for a short time. Generally, the mind is still clear. Inhale fresh air, and after leaving the poisoned environment, the symptoms will soon disappear, generally leaving no sequelae. 2. Moderate poisoning lasts a little longer, with 30% ~ 40% of carboxyhemoglobin in the blood. On the basis of mild symptoms, you may collapse or coma. The skin and mucous membrane show cherry red peculiar to gas poisoning. If the rescue is timely, you can wake up quickly and fully recover within a few days. There are generally no sequelae. 3. In severe cases, it is found too late, too much gas is inhaled, or high concentration of carbon monoxide is inhaled in a short time, and the blood carboxyhemoglobin concentration is often above 50%. The patient is in a deep coma, with various reflexes disappearing, incontinence, cold limbs, decreased blood pressure, shortness of breath and imminent death. Generally, the longer the coma, the more serious the prognosis, and the sequelae such as dementia, decreased memory and understanding, and limb paralysis often appear. Concentration absorption time and symptoms 0.02% 0.04% 0.08% 0.16% 0.32% 0.60%1.28% 2-3 hours mild headache 1-2 hours headache and nausea 2.5-3 hours headache and vomiting for 45 minutes. 2 hours can cause death for 5- 10 minutes with headache, 30 minutes can cause death for 1-2 minutes with headache, 10- 15 minutes with gas poisoning mainly refers to carbon monoxide poisoning. First, the symptoms of carbon monoxide poisoning with different concentrations are listed as follows: The symptoms of carbon monoxide poisoning with different concentrations (1) quickly and timely rescue the poisoned person from the gas danger zone, carry him to a place with fresh air, unbutton his clothes and belt, and pay attention to keep warm. The rescue site should be quiet and ventilated, and there should be a special person to maintain order. (2) Patients with mild poisoning, such as headache, nausea, vomiting and other symptoms, can be directly sent to a nearby health care station for emergency treatment. (3) Those with severe poisoning, such as unconsciousness and foaming at the mouth, should inform the anti-virus personnel and health station personnel to rush to the scene for rescue. (4) If the poisoned person has stopped breathing, he should immediately do artificial respiration and use resuscitator at the scene, and notify the anti-virus personnel and health station personnel to rush to the scene for rescue. (5) Before the poisoned person regains consciousness, he shall not be sent to a distant hospital for emergency treatment by ambulance. When he is sent to a nearby hospital for emergency treatment, effective first aid measures should be taken on the way, and he should be escorted by medical personnel. Poisoning first aid principle When gas poisoning occurs in the operation of gas producer, first aid should be given according to the degree of poisoning. 1. When the operator or maintenance personnel on duty find dizziness, they should immediately go to the fresh air, breathe fresh air, and open indoor windows and ventilation equipment to strengthen air convection and reduce indoor carbon monoxide concentration. 2. When you have symptoms such as nausea and asthma, you should lie down in fresh air, relax your clothes and keep warm. And can be sent directly to the nearby infirmary for emergency treatment. 3, when a coma shock, should immediately move to fresh air, artificial respiration, and shall notify the gas protection station staff and medical staff rushed to the scene for first aid. 4, when the poisoned person has stopped breathing, should do artificial respiration at the scene, and use the first aid or artificial respiration first aid, at the same time, should inform the gas protection station staff and medical personnel to the scene for rescue. 5. In the case of coma and no breathing, the rescuer can't be sent far away until he regains consciousness ... >>

Question 8: How to use the gas tank and how to use it correctly? Please check it carefully before use.

Pay attention to the service life of the fuel tank and the attached inspection certificate. The service life of gas tanks is generally fifteen years, not more than fifteen years.

Always check the use environment, check whether the gas tank, gas stove switch and pipeline have hidden dangers of air leakage, and check whether the gas pipeline is cracked and aging. If there is gas leakage, replace it in time to prevent it from posing a threat to safety.

Pay attention to safety when using.

When moving the gas tank, especially when going upstairs or downstairs, handle it with care, and don't collide and squeeze it hard, which will cause safety hazards to the gas tank.

Gas tanks should not be heated near heat sources, naked flames, insolation, baking with fire, hot water pouring, etc. , and the gas in the cylinder should not be poured into other cylinders. It is forbidden to dispose of the residual liquid in the gas cylinder by yourself.

The gas tank should be placed upright, and the steel cylinder should not be put down during use to avoid violent vibration. Nothing should be placed on the tank to avoid ignition in case of fire.

Close the valve after each meal. Be sure to turn off the valve on the gas first, and then turn off the valve on the stove to prevent air leakage.

Don't panic if there is air leakage.

If the air leakage is easy to smell, if it is slight, you can try to close the valve and find a repairman to deal with it. If you find the smell particularly strong, don't handle it yourself. You should turn on the power first to eliminate all static electricity and fire sources. Open the doors and windows for ventilation; Call the property and fire department to handle it. Pay special attention not to make phone calls nearby. The principle is the same as calling a gas station.
