Install liquefied petroleum gas cylinders and stoves in the bedroom. If the air leaks, it will easily lead to suffocation or fire and explosion accidents.
2. How to prevent the switch on the cooker and gas tank from being damaged and leaking?
To master the use of the switch correctly, we should always pay attention to and educate children not to play with the switch. Because the switch is broken or forgotten to turn it off, it is easy to cause air leakage and cause fire or other accidents.
3. Why should someone take care of LPG?
When using liquefied stone gas, always pay attention to the combustion situation, adjust the flame size and color, and maintain normal combustion. Do not boil soup to extinguish the flame, or use a small fire when the flame is blown out by the wind and the switch is not turned off, resulting in a large amount of liquefied gas leakage, which will lead to fire or explosion accidents in case of open fire.
4. What are the causes of air leakage?
(1) The switch on the gas cylinder is not closed or the compression nut under the handwheel is not tightened;
(2) The oil-resistant hose is aging, cracked, burned or the socket is loose;
(3) The cock switch on the cooker is not tight;
(4) The hand wheel of the pressure reducing valve is not tightened or the rubber washer is lost, damaged, deformed or fallen off.
5. How to identify the leakage of LPG cylinders and cookers?
Every time a gas cylinder is changed or a special smell is smelled, or the sealing rubber sleeve is found to be damaged, the user can smear all the joints with soapy water. If bubbles appear, it means air leakage. It is forbidden to use open flame to check air leakage.
6. What should I do if I find air leakage?
(1) If air leakage is found, first turn off the angle valve switch and open the doors and windows for ventilation. It is forbidden to use all kinds of kindling, and do not turn on or turn off lights or other electrical equipment. Please ask the professionals of the supply unit to handle it.
(2) If the air leakage is large and the angle valve switch fails, first of all, it is necessary to prevent all kinds of kindling from approaching, and do not switch lights or other electrical equipment. In addition to calling the police immediately, wrap it with plastic sheets and other things as soon as possible to prevent leakage, and ask the professionals of the supply unit to handle it.
7. What should I do in case of fire?
(1) If the joint of cooker, hose and pressure reducing valve leaks and the fire is not strong, just turn off the gas cylinder angle valve switch, which will automatically turn off under normal circumstances. If the fire is large, a large piece of wet cloth can be used to put it out;
(2) If the joint between the gas cylinder and the angle valve is on fire, or the angle valve cannot be closed due to fire, or the angle valve switch fails due to fire, on the one hand, the gas cylinder should be cooled with water, and the flame should be put out quickly after being soaked with quilts and blankets, and then try to bind up the leakage, and ask the professionals of the supply unit to deal with it as soon as possible. Send it to the supply station for processing;
(3) If there is a fire indoors, don't panic, quickly turn off the angle valve switch, unscrew the pressure reducing valve or cut the hose, and move the gas cylinder to a safe and open place outdoors. If the temperature of the bottle is high, cold water should be used to cool it, and the supplier should be informed to handle it.
What security checks should users do regularly?
(1) Before ignition, check all kinds of equipment for oil leakage. If there is a leak, it can't be ignited.
(2) Before going to bed, when going out and after use, check whether the switches of gas cylinders and cookers are turned off.
(3) Before opening the angle valve, check whether the switch is closed, in case there is no connection after the last use, and then open it forcibly when using it next time, which will easily damage the angle valve and even cause an accident.
(4) Always check whether the gland hexagon nut of the gas cylinder angle valve handwheel is loose; Whether the oil-resistant hose is broken; The connection of oil-resistant pipelines should be tight.
Precautions for users to use LPG safely:
1, a separate brick kitchen should be used to properly place liquefied petroleum gas equipment.
2, gas cylinders must be placed upright, are not allowed to lie flat or upside down.
3, gas cylinders must be far away from heat sources, placed in a place that is easy to move, there is no flammable around, well ventilated. The distance between the furnace and the bottle is more than 80 cm, and it is not allowed to heat the cylinder in any form.
4. Before installing the pressure reducing valve, check the sealing rubber belt to ensure that there is no deformation or defect. The handwheel of the pressure reducing valve should be aligned with the valve port and rotated counterclockwise to tighten it.
5. Rubber hose, stove switch, pressure reducing valve and the joint between handwheel and bottle valve are easy to leak. Please scrub the inspection area with soapy water to check the leakage, and don't use fire to check the leakage.
6. Do not dismantle or modify the special equipment for liquefied petroleum gas without permission. If you have any questions, please refer them to the supplier.
7. When liquefied petroleum gas leaks, close the bottle valve in time, open the doors and windows, and conduct ventilation and evacuation. It is forbidden to switch all kinds of electrical equipment with naked flames (including cigarette butts) in leakage places.
8. In case of fire, cut off the gas source (close the bottle valve) as soon as possible to avoid putting the bottle in, and report the fire alarm in time. Tel: 1 19.
9, diligent inspection, careful observation, found that the problem handled in time. To ensure safety, please close the cylinder angle valve before going to bed and when going out.
10, it is forbidden to discharge the residual liquid (gas) in the steel cylinder without permission.
