            What should be paid attention to in the use of liquefied petroleum gas cylinders

            2020-12-17 03:12:01Yitian Steel Cylinder
            1. Liquefied gas cylinders must be inspected and qualified by the technical supervision department of bai, and cannot be filled and used without inspection. During the ventilation, the user should conduct a safety inspection of the cylinder and assist the service station to conduct a dynamic leak test on the cylinder angle valve.
            2. Liquefied gas cylinders cannot be stored in the bedroom, and people cannot sleep in the room where the liquefied gas cylinders are placed.
            3. The liquefied gas cylinders should be kept away from open flames and high temperatures, and it is strictly forbidden to use liquefied gas in the same room with other fire sources.
            4. Both ends of the hose connecting the steel cylinder and the cooker must be fastened with hose clamps. The gas stove is placed horizontally. The distance between the cylinder and the outside of the cooker must not be less than 0.5 meters, and the length of the hose must not exceed 2 meters.
            5. When the gas stove is ignited, first open all the angle valves on the cylinder, and then light the stove. After use, the gas stove and the angle valve of the liquefied gas cylinder should be closed.
            6. When installing and unloading the regulator, carefully check that the sealing rubber ring on the front of the regulator should be intact, otherwise it cannot be used. When installing the regulator, tighten the regulator handwheel and open the cylinder angle valve for inspection. Whether each interface is leaking.
            7. When the liquefied gas stove is in use, someone should take care of it to avoid boiling soup, boiling water, or being blown out by the wind, causing the liquefied gas to leak.
            8. Because the liquid in the cylinder is reduced and the pressure is low, do not use fire or hot water to heat the cylinder when the flame is not strong. When the pressure of the liquefied gas is insufficient and cannot be burned normally, the cylinder should be sent to the gas supply unit to dispose of the residual liquid. The user shall not pour the residual liquid outdoors or in the sewer by himself. This is prone to fire accidents.
            9. Frequently check whether the cylinders, stoves, etc. are leaking. You can apply soapy water to the angle valves, pressure regulators, stove switches, and hoses of the cylinders to check. If bubbles emerge from the smear, close the cylinder angle valves immediately. And report to the gas supply unit for repairs.
            10. When the smell of liquefied gas is smelled, it indicates that there is a leak. The angle valve of the cylinder should be closed immediately, and all open flames should be cut off. All electrical appliances should not be turned on or off. Doors and windows should be opened for ventilation, and the gas supply unit should be reported for repair.
            11. When you encounter a fire at the connection part of the steel cylinder and the regulator, or accidentally knock the cylinder over and the fire expands, you must immediately grab the steel cylinder guardrail to lift the cylinder, and then cover the steel cylinder guardrail with a wet towel. Close the angle valve of the cylinder and the fire will go out. Or use "dry powder fire extinguishing agent" to quickly spray the fire place, close the angle valve of the cylinder immediately after the fire is extinguished, and report to the gas supply unit for repair.
            12. When an external fire threatens a liquefied gas cylinder, immediately close the angle valve of the cylinder, remove the pressure regulator, and immediately move the cylinder to an outdoor safe place.
            13. When the switch of the cylinder fails, the closure is not tight, and the flame of the gas cooker cannot be extinguished, immediately stop rotating the cylinder angle valve to avoid serious damage to the angle valve and cause a fire accident. You can directly close the cooker valve and report immediately. Gas unit maintenance.
