How to avoid explosion of LPG cylinder? To "Identify" LPG cylinders.

As a special equipment, LPG cylinder brings convenience to life, but also has certain security risks. If the LPG cylinder can not be identified, used correctly and the unexpected problems can not be handled properly, the safety accidents of LPG cylinder may be caused.

1. How to "identify" LPG cylinder?

(1) Scrapped Cylinders: For LPG cylinders with a design service life of 8 years(China National Standard), it is allowed to extend the service life after safety assessment, but the maximum extension time shall not exceed one inspection cycle. That is to say, the theoretical service life of the gas cylinder is 12 years at most(China National Standard), and the gas cylinder beyond the service life shall be forced to be scrapped. This information can be determined from the "end of use date" of the cylinder coating information.

(2) Expired Cylinders. The commonly used YSP35.5 (usually 15kg cylinder) LPG cylinder shall be subject to regular inspection once every four years(China National Standard), and it can only be used after passing the inspection. The cylinder that is overdue but not inspected cannot be filled and used again, and it needs to be sent to the special cylinder regular inspection agency for inspection, and the inspection information can be found from the cylinder inspection information.

(3) Cylinders severely corroded or deformed. The cylinders with serious appearance deformation or large area of corrosion on the cylinder surface shall be inspected in advance. In order to ensure their own safety, users can refuse to use such cylinders.

2. To Learn how to use LPG cylinders correctly.

Besides learning how to identify cylinders, it is also important for users to use cylinders correctly and scientifically. The correct use of LPG cylinders can extend the service life of the cylinders, reduce the probability of accidents, and ensure the safety of users.

(1) Cylinders shall be placed upright to avoid sunshine, open fire and direct heating with hot water or other heat sources, which will cause cylinder corrosion and damage and shorten the service life of cylinders.

（2）The distance between the LPG cylinder and the stove shall be no less than 0.8m, and the length of the special rubber hose for LPG used shall be 1-2m.Rubber hose is easy to be aging, and it should be replaced every two years.

(3) Users can regularly use soapy water to detect leakage, spray soapy water on the connection part of regulator, LPG cylinder valve and rubber hose, the surface of special rubber hose, the connection part of rubber hose and stove, check whether there is damage, fracture and aging, observe bubbles to determine whether there is air leakage, and replace the rubber pipe immediately if found.

(4) In the process of use, if there is no ignition for more than two times, it is necessary to stop the ignition immediately, stop for two minutes, wait for the gas to dissipate, and then try to ignite, during which, it is forbidden to use the mobile phone or touch the electrical switch.

(5) In the process of using LPG, if it is found that the bottom of the pot or pot is blackened or the flame is red or yellow, the proportion of gas and air may not be appropriate at this time. It is necessary to adjust the damper to normal until the flame is blue.

3.How to Deal with LPG Cylinder Emergency?

Liquefied Petroleum Gas (LPG) has the characteristics of flammability and explosiveness. It is easy to bring danger if it is used carelessly in daily life. Therefore, it is very important to deal with the problems timely and scientifically.

(1) Gas leakage. When smelling the odor, LPG may have leaked. At this time, cut off all open fires, and smear soapy water on the corner valve, pressure regulator, stove switch and rubber tube of the steel cylinder for inspection. If bubbles appear on the coating, it means that the air has leaked, immediately close the corner valve of the steel cylinder, open the doors and windows for ventilation. Do not use the mobile phone or touch the electrical switch, and move to the ventilation safety place to supply air Unit repair request.

(2) LPG on fire. In case of LPG is on fire, using wet towel or gloves to quickly close the cylinder valve, and then open the doors and windows for ventilation. Do not touch the telephone or indoor electrical switch. If the cylinder falls on the ground or the cylinder valve is burning towards the ground, don't get close to it blindly. They can use the cover to cool the cylinder to prevent explosion. Call the emergency telephone of the gas supply unit or call fire telephone for alarm.
