A property manager in Hangzhou climbed out of the ninth floor window and put out the fire on the 10 floor. What caused the fire?

Smoke emitted from the outdoor air conditioner of a family in Hangzhou, Zhejiang. Customer's home is on the 10 floor. At this time, the property manager climbed out of the window on the ninth floor and extended the fire extinguisher to the outdoor air conditioner on the 10 floor for spraying. Because the property manager was almost suspended in mid-air, someone hugged his feet tightly. It is said that after this process is completed, the property manager's legs are weak.

First of all, the cause of the fire

From the point of view that the fire in 10 household was caused by outdoor air conditioning, it may be because the outdoor air conditioning was used for a long time, which led to dust accumulation in the internal facilities, and it was too hot for a long time, which eventually led to the fire.

Second, follow-up treatment

After the property manager put out the fire, he had to rule out the possibility of re-ignition with his colleagues, so after telephone communication with the owner, they broke into the house and found signs of re-ignition. Moreover, the glass of the air-conditioned outer wall room has cracked initially because of the high temperature. At this time, the property manager's contract is to use three fire extinguishers and then control them flexibly, and further confirm that they will use the fire hydrant hose in the corridor to cool down again in case of power failure. They will breathe a sigh of relief when the ambient temperature drops. By the time the firemen arrived, everything had actually been solved.

Third, the property manager

The property manager said that when he put out the fire, he just wanted to put it out and had no time to think about it. In retrospect, others think it is really terrible that such a high floor has no protective measures. In addition, when he got off work, he met the stone building owner who came in a hurry. The owner said that the house was for relatives at home. At present, he found that the loss was not great. He expressed gratitude for the property. However, the cause of the fire is likely to be parabolic at high altitude or aging of the circuit. Because the owner did not apply for fire identification, it could not be confirmed. It is very likely that the outdoor unit of the air conditioner has been used for too long and the circuit is aging, thus causing a fire. Fortunately, the fire was put out in time. Because the inactivation method of the property manager is basically correct, it is very important to ensure your own safety while putting out the fire.
