[Firefighter's Note] Broken liquefied gas tank

Liquefied gas tank leak

At 18:00 on July X Japan, received a report that a cell upstairs A gas tank leak, the squadron sent two cars to disposal.

The road to the community was relatively narrow. After arriving at the scene, Ah Sir had just smelled a smell on the outskirts of the community. He arranged a group of people to be on site to guard against fire and smoking.

Psychology is a bit tricky: If it's okay to catch fire, it's not so controllable if it leaks.

By asking people alarm, alarm sister said, the house is not used by long-term gas tank, the tank bottom is corroded, leaking damaged, arrived home just to smell the stink smell of gas (LPG itself is tasteless, in order to facilitate real-time discovery, join Thiols, thioethers, and other odoriferous substances ) , so immediately closed down to the alarm downstairs.

A Sir carries a flammable gas detector and goes to the 301 room to carry out specific reconnaissance. As soon as the door is opened, it is a strong gas smell.

This is indeed not so easy to deal with, ah, such a strong taste that gathered a lot of liquefied gas, mainly her sister's doors and windows are closed.

Three orders were carefully made underground:

1. After you find the alarm eldest sister to understand the location of the kitchen, first arrange it to wait in the safe area downstairs;

2. Arrange 2 soldiers to guard on the 3rd floor and above to prevent the masses from going downstairs to eat melons, play a lighter, and smoke a cigarette;

3. The scouting personnel carried out internal reconnaissance with Ah Sir to find the leaked liquefied gas tank.

In the kitchen, a leaking liquefied gas tank was quickly found and it was true that the interior windows were closed. Fortunately, no one has fired a bit, or else the house is not yet blown up by the two big sisters.

Therefore, carefully look at the last Arab Sir write the essay: "A gas leak how to dispose of Sir bring you up posture?!", Or necessary drops, Province of day careless folly.

As a result, A Sir arranged for San San to pick up the liquefied gas tank to open upstairs and dilute it with a water gun. Li Si and Wang Wu opened the window slowly and opened the door to ventilate the room so as to minimize the concentration of liquefied gas in the room.

Due to the small size of the damaged opening, the leakage rate is extremely slow, and the weight of the liquefied gas tank has not been effectively reduced by one hour after the dilution time has passed. The people who are warned to go home on the periphery are very anxious.

Occasionally, the masses want to break through the alert, whether there are other better disposal methods and dispose of the police as soon as possible, and the small partners of the police are also very anxious.

Thought to speed up the discharge rate, people were able to find a super large municipal trash can, fill the trash can with water, and then upside down the liquefied gas tank into the water, supplemented with a counterweight pressure.

The reason for inverting and assisting in weighting is because: 1. The valve is opened and the liquefied gas is discharged into the water. 2. The liquefied gas tank is floating in the water, so it is necessary to supplement the tank with the counterweight.

After inverting, the valve is opened, the exhaust speed is increased, and the liquefied gas is discharged into the water, so that a large number of bubbles appear in the water. The gas in the liquefied gas tank was quickly drained, and a large amount of liquefied gas was also floating above the trash can.

To avoid the accumulation of liquefied gas in the sewer, disperse the water into the sewer.

Dispose of and return to the team.

Brief commentary

After thinking about going back to the team, such cases are often handled by themselves, but many times they are lazy and do not make a summary. It is very wrong, and how to say it should also leave a reference for later people.

Ever since then, they have consulted experts and old firefighters on liquefied gas angle valves, and feel that the following disposal methods are also good:

Airway

Intelligent Angle Valve Experts: Learn from gas traffickers, find an empty liquefied gas tank, and a liquefied gas pipe with two lances ("tools can be found at liquefied gas stations or gas traffickers"). Tanks can guide tanks. If the valve is melted, this method is not feasible.

Taiwan's firefighter Lin Jinhong: Under the cover of water guns, he used Silicon sealant "A universal X treasure has found it, and his practicability remains to be studied." He sealed the leak and moved it.
