[Fire experiment] Fire extinguisher can not be used like this!

Xiaobian wondered

Why is there always someone

Take the fire extinguisher "doing bad things"

we all know,

Fire extinguishers are used to extinguish fires.

But some people use it to hurt people.

This is not

Another woman

I was stricken...

At 1:00 in the morning on the 3rd , Xi'an City West Third Ring Road outside the hotel lobby. The man used a dry powder fire extinguisher and sprayed it directly to the waiter at the front desk of the hotel. Xiao Zhang was sent to a hospital in Xi’an.

It is understood that on the evening of December 2 Xiao Zhang night shift, the man is a customer in the shop, the reason why there will be such extreme behavior, the cause was actually a call reservation, the man did not submit a name to request the booking result was rejected by Xiao Zhang , then there are all kinds of abuse.

At 1:00 in the morning, the man drove to the hotel and did not speak too much. The man raised the hotel’s fire extinguisher. Xiao Zhang also reminded him that there was monitoring here, but a shocking scene still occurred.

After a period of white smoke, Xiao Zhang's body was an extinguishing agent. Xiao Zhang blinked his eyes with one hand while dialing 110 . The security guard immediately pulled the man away. After a while, the man left. Ten minutes after the incident, police from the Afang Palace police station in the area arrived at the scene.

It is understood that Xiao Zhang from Anhui Province has just been working in this hotel for two or three months. This happened. The most regrettable thing is that there is less than a month is Xiao Zhang's day of great joy.

The family of Xiao Zhang: "It was a month before we would get married. She told me last night that she was afraid she could not see her eyes. She said last night that she did not want to get married."

Doctor: "After chest and chest CT , taking into account some damage to the chest, there is no merger of the lung infection later, but also need to be further observed." At present, the area's A Fang Palace police station is also investigating the incident.

If he does not cooperate, he will hurt and

The law will not let you!

In addition to the above two "fire extinguisher incidents"

Some time ago Xiaobian was online again

The bridesmaid was sprayed all over.

Fortunately, no one was injured on the wedding day!

Fire extinguishers are fire-fighting equipment standing in our lives.

Something that was originally put out of fire,

But used to spray people,

Will it cause harm?

Let's take a look at what everyone says

↓↓↓

The dry powder inside the dry powder fire extinguisher,

What is the substance?

Is it hurting to spray on people?

The truth experiment

Dry powder fire extinguisher material composition?

The team members performed experiments using rabbits and mice. The rabbits and mice were placed in sealed observation boxes.

Next, dry powder was sprayed in the observation box to observe the response of the mice and rabbits.

After the dry powder was sprayed into the box, the rabbit quickly lost its activity, curled up in the corner, and accompanied by convulsions; while the white mouse became arrogant and ran up and down, ten minutes later, a white mouse was still fainting.

Dry powder fire extinguisher sprayed dry powder

Damage to small animals,

So is it really like the above,

What are the toxic substances in the dry powder composition?

Dry powder fire extinguisher dry powder main components are phosphate, mainly ammonium dihydrogen phosphate and sodium bicarbonate, in terms of these two components is basically non-toxic.

 

To our surprise, dry powder is non-toxic and harmless.

Under normal circumstances, dust emitted from dry powder fire extinguishers will settle quickly. However, if sprayed directly at the person, a large amount of particulate matter will be inhaled into the lungs, including tiny particles that many people cannot see. The result is that the lungs inhale large amounts of particulates that can cause acute injury.

Truth Experiment II

How many dry fire extinguisher

Particles that can be inhaled into the lungs?

 

Let’s take a look at the next experiment

Prepare a sealed container and PM2.5 tester

Spray dry powder in a sealed container

It was later found that many particles were suspended in the air, but most of them settled to the bottom. Normally we think PM2.5 is less than 30 when the air is good , and the PM2.5 in the sealed container has reached 500 ! In such an environment, the lungs will inhale a lot of particles.

Why can't a fire extinguisher spray people?

Through the above experiment,

Dry powder in dry powder fire extinguisher itself is non-toxic,

But you can't spray directly at people.

Otherwise, large amounts of particulate matter inhaled into the lungs can cause asphyxiation

Remind everyone: Never use a fire extinguisher to spray directly on the fire, because fire extinguishers' agents can cause wound infections, and the consequences are very serious.

Even if people wear thick clothes, they will also cause casualties. Because the composition of the dry powder fire extinguisher contains 50% ammonium dihydrogen phosphate, 25% ammonium sulfate, it is very corrosive.

In addition to dry powder fire extinguishers, carbon dioxide fire extinguishers are also more common. Never use this kind of fire extinguisher to spray against exposed skin. Because the temperature is -78 °C , it can cause cold burns. There is also a foam fire extinguisher, but such fire extinguishers cannot be used for electrical fires and cause electrical conduction.
