Cautionary Notes
1. Cylinders must be stored in well-ventilated areas, with a distance of no less than 1.5 meters from any flame or heat source. Cylinders are strictly prohibited from being heated with fire, boiled in hot water, or exposed to direct sunlight. Regular inspections should be conducted for gas tightness of cylinder valves and pipe joints, ensuring no leaks. Leak testing can be done using soap water, but open flames are strictly forbidden.
2. When lighting the flame, ignite the ignition material first, followed by opening the gas, do not reverse the order. Always have someone supervising during use, and do not leave it unattended to prevent boiling water from spilling and extinguishing the flame, which could cause the gaseous fuel to leak and lead to an explosion. After using the gas cylinder, ensure the valve is tightly closed to prevent gas leakage.
3. The liquefied gas inside the cylinder should not be completely exhausted; a certain residual pressure must be maintained. The residual pressure should generally be greater than 49.03 kPa (i.e., 0.5 kg/cm², gauge pressure) to prevent air from entering the cylinder. After the liquefied petroleum gas is used up, the remaining residue in the cylinder is also a flammable substance and should not be poured out arbitrarily to avoid fires caused by the leakage and evaporation of the residue.
4. LPG cylinders are pressurized containers that require proper maintenance and regular inspections. Prevent the cylinders from falling or being struck during handling and use. Do not use metal tools to敲击 open the valve, and protect them from direct sunlight and prolonged exposure to rain. Cylinders should be inspected every 2 years.
5. Although the explosive range of liquefied petroleum gas (LPG) is not very wide, its lower limit is small, making it easy to ignite and explode upon leakage. Additionally, since LPG is heavier than air, it tends to flow downwards in the air, accumulating in low-lying areas and posing a hidden danger of gas explosion. Therefore, in areas where gas leakage is likely, relying solely on window ventilation is insufficient; attention must also be given to proper ventilation at the lower levels.
6. Upon discovering a liquefied gas leak indoors, promptly open windows and doors for ventilation, allowing the gas to disperse towards a direction without open flame. Strictly prohibit any fire nearby. Use the facility only after the fault is rectified and the distinctive odor has dissipated. Dispose of any leaked liquid on the ground by covering it with sand and soil before removing it to a safe location. In case of a gas cylinder fire, immediately close the valve, move it to an open area outdoors, and extinguish the fire using dry powder extinguishers, CO2 extinguishers, or by covering it with a wet sack.
7. Educate children not to tamper with gas cylinders carelessly, and users must be aware of the safety knowledge for handling gas cylinders.
