How to use gas safely?

First, what should I pay attention to before using gas?

When using gas, be sure to pay attention to whether there is any odor, and then ignite 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 cycle of cylinders and attach the inspection standard.

2. Please keep the cylinder upright to avoid violent vibration.

3. Place it in a well-ventilated place to avoid sunlight.

4. Don't use the cylinder upside down.

5, don't put items on the cylinder, so as not to ignite.

Third, how to find out whether the gas pipeline leaks?

When you suspect that the gas pipe (pipeline) at home is leaking, don't use matches or lighters for ignition test, but use soap bubbles to check whether there is leakage.

4. Where is the safest place to install the gas water heater?

It should be installed in a well-ventilated outdoor place to avoid carbon monoxide poisoning accidents.

5. What is the phenomenon that gas fireworks show red flames? What's the danger? What should I do?

The gas flame is normally light blue, and if it is found to be red, it means that the combustion is incomplete. If there is danger of carbon monoxide poisoning, please ask a gas professional to repair and adjust the stove immediately.

6. How did you know about the gas leak?

1, smell-household gas mixed with odorant will have its own taste when it leaks.

2, vision-gas leakage, will cause the formation of foggy white smoke in the air.

3, hearing-there will be a "hissing" sound.

4, touch-hands close to the leak, there will be a cool feeling.

Seven, how to deal with gas leakage?

1, turn off the gas switch immediately.

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 poison gas kill people?

1, the gas itself is not toxic, but it has anesthetic and asphyxiating effects, 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 hypoxia (carbon monoxide poisoning, leading to death).

Nine, gas and air are not used enough, how to do carbon monoxide poisoning?

1, turn off the gas switch.

2. Open the doors and windows for ventilation.

3. Provide fresh air for the injured.

4, untie the shackles and clear the respiratory tract.

5, depending on the situation may need artificial respiration or cardiopulmonary abdominal pressure.

6, before the gas smell dispersed, don't turn on or off any power switch, so as to avoid sparks and fire.

What are the symptoms of carbon monoxide poisoning?

1, headache, dizziness, nausea and vomiting. 2, there will be a strong sense of collapse, rapid breathing and pulse, vague consciousness, and the body can't move independently. 3, flushing, loss of consciousness, respiratory arrest, convulsions, leading to cardiac arrest and death.

Twelve, such as accidentally cut off the gas pipeline due to sewage pipeline construction, how to do?

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 is on fire, don't put out the fire hastily, draw a warning line and call the police as soon as possible. Residents or pedestrians near the pipeline cut-off 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 enclose the scene with ropes and write down slogans such as gas leakage to remind people and passers-by.

(a) users are not allowed to dismantle and change the pipeline gas metering facilities without authorization.

Pipeline gas is a colorless, odorless (containing very little gas) toxic and combustible gas. Generally speaking, a small amount of leakage is difficult to detect. Therefore, when installing the gas pipeline, the pressure test is used to check whether the gas in the pipeline leaks, but the user has no condition to check the leakage when disassembling it privately, and it often leaks after disassembling it privately. This kind of thing happened many times when residents in Daguan Community renovated their houses, which made it impossible to send gas. Because as long as one household leaks, all users on a riser can't send gas. In Fuyang, because the user dismantled the gas pipe privately, the gas leaked and three people in the whole family died of poisoning.

(2) The gas pipeline cannot be installed in the wall.

Because once there is a leak, the gas may flow around and enter the neighbor's bedroom, causing casualties.

(3) Gas meters, water heaters, etc. Can't be installed in hanging cabinets and inner wall cabinets without vents. Because leakage is not easy to find, it is easy to accumulate and reach explosive concentration after leakage.

(d) gas appliance and temperament match.

Carefully check whether the gas appliances such as cookers and water heaters are consistent with the supplied gas, whether the clamps at both ends of the pipeline connected with the cookers are installed and fixed, and whether all valves are closed.

(5) Safety during first ventilation

In general, the first gas supply and the first ignition should be carried out by pipeline gas professionals. Why not just send gas for ignition? Because there is air in the gas pipeline before the primary gas transmission, the gas and air mix to form explosive gas after the gas transmission, so the air in the pipeline must be released until 100% is gas before ignition. If the user ignites privately and the mixed gas is not completely discharged, within the range of 5%-40%, a waterfall accident will occur when igniting.

(6) Pay attention to safety after using gas.

After using gas, users should brush soapy water at the joints of rotating parts such as indoor standpipe tee, gas valve in front of the table, valve handle, etc., and check for air leakage again. If there are bubbles in the soapy water, there is a leak here. Stop using it immediately, and call the maintenance center of the pipeline gas company for maintenance immediately to avoid accidents. When the gas is not used at night, record the last digit of the gas meter, open the kitchen window, close the valve in front of the furnace in front of the hose, and close the door connecting the kitchen with the living room and bedroom. Before using gas the next day, check whether the last digit of the gas meter has moved. It doesn't usually change. If there is any change, there may be a leak in the pipeline from the back of the gas meter to the valve in front of the furnace. Please call the emergency maintenance center immediately and ask them.

Here is the same sentence. When gas is not used before going to work or at night, the valve in front of the furnace (that is, a valve in front of the rubber pipe) should be closed. Don't just close the valve on the gas stove without closing the valve in front of the stove. In xx city, because some users only turn off the valve on the gas stove, but not the valve in front of the stove, gas leakage occurred at a pressure regulating station in Minsheng at a uniform angle. When the medium-pressure gas rushed into the low-pressure pipe network, the hose in the user's home was washed away, and a large amount of gas leaked out. This happened at night when people were sleeping, causing a tragic accident in which seven people died.

(seven) safety matters that should be paid attention to in the process of gas use.

First of all, we should pay attention to ventilation and discharge the burnt waste gas outside. Because gas consumes a lot of oxygen in the combustion process, one cubic meter of pipeline gas needs five cubic meters of fresh air for combustion, and the waste after combustion may generally contain 600 mg/nm of CO. If this waste gas is not discharged outdoors, it will also cause personnel poisoning. If the air used for combustion is not fresh air, that is, the oxygen content is lower than 20.8%, it will produce waste after combustion.

The CO content in the air will increase greatly. When a user (with an area of about 40m) uses an 8-liter gas heater, the CO content in the air will reach 1200mg/nm after 8 minutes, and then it will rise linearly, so the measuring instrument cannot measure it. Therefore, when using gas appliance, we must pay attention to ventilation to ensure that the indoor CO content does not exceed the complete standard.

Secondly, when boiling water or cooking thin food, be sure to prevent the water from overflowing after boiling and put out the fire. The gas stove was still on, and a large amount of gas leaked out, causing poisoning and explosion.
