How to use bottled liquefied gas safely?

Gas, liquefied gas, natural gas and other combustible gas to its clean, economical features to bring convenience to millions of households, but its fire risk is also increasingly exposed. Such as the daily gas leak can cause fire, explosion, poisoning. In particular, bottled gas cylinders, if not stored, used, maintained and managed as required, will destructively withstand as much as one heavy bomb in the event of an explosion.

1, common causes of fire liquefied gas cylinders in use (1) gas pipes, angle valves, pressure reducing valves, cylinders, gas pipe joints and other parts loose aging, sealing rubber ring off or aging loss of elasticity, causing gas leaks. (2) serious aging residual gas cylinder, compressive strength decreased, resulting in gas leaks.

(3) handling process impact, transport process collision caused by gas cylinder rupture.

(4) The user pour gas or unauthorized dumping liquefied gas residual liquid fire.

(5) without pressure reducing valve or manual manual decompression direct gas supply.

(6) Cylinder lying, the liquid directly without gasification spray.

(7) gas hose is too long, the middle of the curve, the use of switching procedures upside down, the hose parts and hose trapped in the residual gas accumulation in the process of ignition again flashover.

(8) cooker soup fire spilled or blowing fire extinguishing stove fire caused by gas leaks.

(9) In the process of using fire to leave the valve has not been closed, burning molten metal solution ignite combustible material or hose.


2, Precautions for use Bottled gas (liquefied petroleum gas) use common sense Such as cylinders must be placed in the shade. Do not close to open flame or high temperature, to avoid danger. Cylinders must be easily removable for rapid movement to safe open areas in the event of special conditions. Cylinders must be erected, not inverted or horizontal. Otherwise liquefied gas into the regulator liquid state, prone to accidents. Cylinders are strictly prohibited in humid or corrosive places. When handling to be light, can not be on the ground roll gas cylinder. Do not use boiling water bottles, ignition roasting bottles, the sun under the sun bottle, metal or other hard objects may not be free to hit the gas cylinder, otherwise it is likely to cause gas cylinder damage, or even a fire or explosion accident.

Care should be taken, for example, between the cylinder and the cooktop, that the distance between the cylinder and the outermost side of the cooktop should be no less than 80 cm. Hose connecting the cooker should be naturally drooping under the cooktop, and keep the distance of 10 cm or more, so as not to be charred by fire, blown, causing an accident. Should always check whether the hose loosening, loss, cracking deterioration. Found that the phenomenon of aging hose to timely replacement of high-quality gas hose. Hose and cooker, valve connection is best to use a good fixed clamp hoop tight. Pressure relief valve installation must be correct, it is with the cylinder angle valve is anti-buckle connection. Before the regulator, you should first check the seal rubber band is intact, if found lost or deformed, is strictly prohibited to continue to use. When installing, rotate the handwheel to the left to tighten it, remembering not to use too much force to avoid air leakage. Regulator maintenance, disassembly is best operated by professionals.



Liquefied gas cylinders do not handle such as can not be self-defeating liquefied petroleum gas residue. Liquefied petroleum gas raffinate is not something that people misunderstand like water, it has strong volatility and flammability, in the event of a spark, it will cause burning or even explosion. As a result of disasters caused by chaos pour residue has been uncommon, it can not be self-pour residue, liquefied gas filling stations in general will be carried out before filling the disabled treatment; users if necessary, contact the professional filling station processing, tens of millions Do not pour residue.


Gas use process should pay attention to these users in the use of gas should be opened in time to open the doors and windows ventilation; stop gas, before going to sleep, leave the house should go home carefully check the stove and pipe valve is closed;

Long-term use of hose prone to aging, it is recommended that the user a year and a half to replace the best and often check the hose and pipe and stove connections are solid, and the hose will be fixed with a good card; to prevent the hose in the process of shedding, resulting in Gas leak, do not sleep in a room with gas, do not ignite gas heating in the room, so easy to produce oxygen deficiency, causing poisoning;

When using gas, to confirm whether the normal combustion after the ignition, the flame is stable.
