Kang Ming took the military uniform and found four people and handed them to them.

After the four of them took it, they couldn't wait to change it on their bodies, and their hair was all coiled, looking much more energetic than before.

"Squad leader, why don't we have that on our shoulders..."Zhang Hua pointed to Kang Ming's shoulder and asked curiously.

Kang Ming didn't understand what she said at first, but then he saw the direction of her fingers and understood, "Are you talking about epaulettes?" This epaulette is only available to our soldiers. ”

Hearing Kang Ming's explanation, the four of them nodded in realization.

"Alright, we're going to start today's mission, let's go." Kang Ming said and took them downstairs to the duty garage, took Wang Junfeng, who was already waiting here, and left the squadron in a car.

Fire propaganda is a very boring and boring job, and it has to be repeated everywhere, and it is necessary to teach them how to escape according to their geographical location.

Today, Kang Ming quickened his pace, and it didn't end before dark, "Tomorrow should be over in one day." Kang Ming said to them.

"Hopefully, we should leave this task to our volunteer fire propagandists." Wang Junfeng muttered to Kang Ming.

Kang Ming pouted helplessly: "That's not good, this is an order given to us by our superiors, and they are likely to ignore some problems when dealing with inspections." ”

Driving back to the squadron, everyone went to the cafeteria to eat and then went back to the dormitory to rest, Kang Ming took four international students to the study room and continued to analyze the firefighters for them.

"Squad leader, I wonder why you are talking about the three major killers of fire today? What does this mean? Could anyone be guilty of a fire? Xiao Rui stood up and raised her hand to Kang Ming and asked her puzzle.

Kang Ming couldn't help but smile after hearing this, it seems that the language barrier is really a big obstacle.

"When I say the three killers of fires, I don't mean someone committing a crime, but the three places that are most lethal after a fire. The first one we call it the gold medal killer - smoke, many people think of the dead in the fire will involuntarily think that they were burned to death, but in fact, more than 60% of them died from smoke. When the carbon monoxide content in the air is 1.3%, a person can be unconscious after a few breaths, which can lead to death within a few minutes. ”

Kang Ming explained to the several of them in a mixed language of Chinese and English.

After hearing this, the faces of several people all changed greatly, they didn't expect the smoke to be so terrifying, it could kill a person in a few minutes.

"So squad leader, what is the second biggest killer?" Sister Fleur stood up and continued to ask.

"The second biggest killer – high temperatures. When the temperature in the fire is higher than 50 degrees, our human body will sweat a lot, and if there is no water and salt supplementation, it will lead to the failure of the human circulatory system. At 70 degrees Celsius, when a person inhales a high-temperature gas, the mucosa in the trachea will be congested, blistered, and the tissues will die.... Finally died. ”

"If you are surrounded by flammable materials, then the temperature will rise to hundreds or even thousands of degrees in just a few minutes, so you can imagine that people can't survive in such an environment."

"Wow, I guess I'm all cooked."

A joke made everyone laugh.

"Squad leader, what about the third killer?"

"The third killer - darkness!"

"Darkness? Why does darkness become a killer? "The first two can be understood, but the third one sounds a little incredible, if the darkness is the killer, then we will live day and night every day.

Kang Ming stretched out his hand to interrupt their discussion: "Normal daytime black is our life, but if you are in a fire, because the fire is out of power, the smoke will make the surrounding situation worse, in this case, many people will panic, fear, so that they trample and jump off the building, these are possible, according to our statistics, the mortality rate of jumping from more than nine meters above the third floor is as high as 95%, so it is absolutely impossible not to take this road." ”

After Kang Ming finished speaking to them, he continued to let them watch a video.

It was a place where they learned things that they didn't learn in society, in school, or in their own country.

Kang Ming would often tell them that as long as everyone understands firefighting, then there will be no unnecessary situations, and this sentence has taken root in the hearts of the four of them, and they all want to bring this concept back to their own countries.

The day is coming to an end with the lights out whistle.

Kang Ming was lying on the bed and suddenly thought of a problem, a very, very serious problem for him.

I seemed to have told my mom yesterday that I would go to the community today and asked her to wait for me..... But... She's not going to sit outside and wait again, is she? Don't, don't, oops.

Thinking of this question, my head became a mess of porridge, and I wanted to call my mother to apologize, but it was a little late for fear of disturbing her rest.

"Ming, why don't you sleep?" Wang Junfeng, who was on the side, watched him keep turning over and asked in a low voice.

"I forgot something important."

Wang Junfeng sat up when he heard this: "What's the matter?" Hurriedly asked.

"It's just.... Forget it, it's okay, I'm going to go tomorrow anyway, hurry up and go to bed. Kang Ming didn't say anything, which made Wang Junfeng's curiosity how to settle down, after seeing Kang Ming turn around, Wang Junfeng quietly got out of bed and sat down next to Kang Ming's bed, and moved Kang Ming's body with his hands: "Say, I can't sleep if you hang my appetite so much." He whispered to Kang Ming.

I also asked for it, why do I tell you this, Kang Ming muttered to himself: "It's okay, I just promised my mother that I would go to the community to publicize today, isn't it delayed?" In order to be able to go to bed quickly, Kang Ming could only tell Wang Junfeng about it briefly and quickly.

Wang Junfeng raised his eyebrows after hearing this: "What do I think is a big deal, won't we go tomorrow?" Let me tell my aunt when the time comes. He replied in a whisper as he walked to his bed.

After finishing speaking, he lay down and covered himself with the quilt and fell asleep.

Jingle bells! Jingle bells! Jingle bells! At two o'clock in the middle of the night, a shrill alarm bell sounded in the corridor, and Kang Ming and the seven of them all turned over and sat up.

"How many shifts are on duty today?" Kang Ming hurriedly asked.

"Second shift." Wang Junfeng replied very firmly.

Before Kang Ming could nod his head, he heard the siren of the fire truck going out.

"Go back to sleep." After Kang Ming finished speaking, he lay down and continued to sleep.

Time passed minute by minute, Kang Ming had not slept here, and at this time the alarm bell sounded again: "All go, all go!" The loudspeaker in the corridor came the shouting of the communications soldier.
