First, what is the pipeline gas
Gas includes artificial gas (commonly known as gas), liquefied petroleum gas (LPG), and natural gas. At the current stage, most of the pipeline gas used in China's cities is pipeline liquefied gas. The pipeline liquefied gas is obtained by gasifying the liquid liquefied petroleum gas from the gas source point (gasification station) and then sending it to thousands of households through the municipal pipe network, which is safe, stable, hygienic and convenient compared with the bottled gas supply.
Second, the general knowledge of liquefied petroleum gas
Liquefied petroleum gas is generally a by-product of petroleum refining, so its market price generally fluctuates with the international oil market. The main components of liquefied petroleum gas (LPG) are propane, propylene, butane, and butene (commonly known as C3, C4). Gaseous liquefied petroleum gas is heavier than air (about double the weight). Once the leakage is not easy to dissipate, and when the liquefied petroleum gas is mixed with air to a certain concentration (1.5 to 9.5%), it will explode when exposed to an open flame, so the pipeline gas cannot Introduced into the basement. Liquefied petroleum gas is colorless and odorless. A special odor gas is added to the daily use of liquefied petroleum gas. Once a leak occurs, a small concentration can be detected. Liquefied petroleum gas itself is non-toxic, but people in the room filled with liquefied petroleum gas will feel uncomfortable. When inhaled in a large amount, they may paralyze nerves or lack oxygen, and accidents may occur.
Third, safe use of gas
1. The complete combustion of liquefied petroleum gas consumes a lot of fresh air, and the complete combustion of 1 cubic meter of liquefied petroleum gas requires about 30 cubic meters of air. Therefore, indoor air circulation must be maintained when using liquefied petroleum gas.
2. Before ignition, you should smell the liquefied smell in the room. When the air leak is suspected, the window should be ventilated in time, the fire switch should not be used or the electric switch should be used. When there is an open fire outside the door, the door should not be opened, and the main Valve should be closed immediately and the pipeline gas company should be notified for maintenance.
3. In normal operation, the burner should be turned on and the knob switch should be turned on to adjust the air intake to make the flame stable blue. The switch must be turned to the OFF position after each use of the oven.
   4. When using liquefied petroleum gas, someone should look after it, pay attention to the burning situation at any time, avoid the boiling of the food to extinguish the flame or blow the flame through the wind. Once the flame is suddenly extinguished, immediately turn off the burner switch, if necessary, close the main valve of the pipeline. Confirm that there is no leakage in the room before you can continue to use it.
   5. Under normal circumstances, the hose should not be worn through the wall. The length should not exceed 2 meters. The hose should be inspected frequently. If cracks, hardening and softening are found, replace the new oil-resistant hose.
   6. The selection of domestic gas water heaters shall be qualified by the gas company and shall be installed or accepted by the pipeline gas company before they can be used.
   7. It is forbidden to use in-line water heaters.
   8. Flue, strong drain water heaters can be installed in bathrooms that are effectively exhausted. The bathroom volume should be greater than 7.5 cubic meters and the room height should be greater than 2.4 meters. Air inlet holes or gaps with a cross-sectional area of ​​not less than 0.02 square meters shall be left in the bathroom door or the lower part of the wall.
   9. The water heater should be installed on a refractory wall, and there must be no power lines, electrical equipment and flammable materials on the upper part.
   Fourth, gas leakage prevention
   When discovering or suspecting a leak of liquefied petroleum gas, the following measures should be taken immediately:
   1. Quickly turn off the valve on the gas pipeline.
   2. Do not switch on or off any electrical or electronic devices and use the phone on site.
   3. Extinguish all fires.
   4. Open the doors and windows and drive the LPG to the outside with a broom or a fan.
   5. Go to the outdoor to repair the phone, notify the pipeline pipe gas company to send someone to deal with.
   6. If you find a neighbor's liquefied petroleum gas leak, you should knock on the door and do not use the doorbell.
   7. If the situation is serious, you should leave the scene and call the "119" fire alarm.
   8. Check the leak method: Turn off the gas appliance switch, open the main valve of the household, and use the soapy water to apply the continuous foaming point in the leaky part as the leaking point. It is forbidden to use an open flame to check for leaks.
