Winter is coming.
,
Dry weather
,
This is a season of frequent fires.
The energy is increasing,
Power supply security puts forward higher requirements.
Especially since winter,
power usage
Rapid increase,
The situation is particularly grim,
Coupled with the aging of some power supply equipment and lines,
The whole power supply line is very long.
This period is in an overload state. In order to avoid fire.
,
Take precautions and protect students' property.
safe
,
I will introduce some tips on fire prevention, electricity prevention and theft prevention in winter.
Littering cigarette butts causes fires;
In winter, it is windy and rainy, cold and dry. In particular, be wary of fires caused by smoking and throw them around.
Cigarette butts are a bad habit of many smokers. Smokers should consciously protect themselves and actively promote smoking ban in dormitories.
Fire caused by electrical failure:
Check before use and maintain after use to avoid aging, disrepair or frequent use of the line.
Touching wires during transportation leads to fire accidents. Don't use kerosene stoves in the dormitory. Alcohol lamps are flammable items.
How to make a fire alarm call?
1
) After calling the fire alarm, make clear the detailed address of the fire unit, community, street and house number;
2
) explain what is on fire and how it is on fire;
three
) Identify the fire location, burning substances and burning conditions;
four
) the alarm person should make clear his name, unit and telephone number;
five
) after the alarm, assign a special person to wait for the arrival of the fire truck at the intersection and guide the fire truck to the fire section, so as to be fast and accurate.
Arrive at the scene of the fire. It is the responsibility of every student to call the police in time when a fire alarm is found.
We should try our best to put out the fire at the initial stage.
At the beginning of the fire, the fire area was small and the temperature was low.
It is the most favorable time to save. If a fire is found at this stage, as long as it doesn't
If you miss the opportunity, you can put out the fire with little manpower and fire extinguishing equipment, even a bucket of water and a fire extinguisher.
The disaster loss is small. Therefore, attention should be paid to fire fighting in the early stage.
What should I do if I catch fire when I escape?
Never run after a burning man.
Because it's getting stronger and stronger.
This is because people will accelerate air convection and promote air convection when running.
Burning,
The fire will be more violent.
Run,
Not only can't put out the fire,
Instead, he took the fire somewhere else,
It is also possible to expand the fire.
This is very dangerous. Should:
1
Try to undress first, immerse in water or step out with your feet;
2
If it is too late to undress, you can also lie on the ground and crush the flames on your body;
three
) You can jump into nearby pools and ponds to put out the fire. If the burn area is large, do not jump into the water to prevent infection;
four
Don't spray a fire extinguisher directly on a burning person, because most fire extinguishers will cause a burning feeling.
Dyeing.
Smoke prevents people from escaping mainly in the following aspects.
1
) the toxicity of flue gas. Although not all the components in smoke are toxic, non-toxic gases can also hinder people's breathing.
Reduce the concentration of oxygen in the air, leading to human death due to lack of oxygen.
2
) Decreasing characteristics of flue gas.
The reduction of smog means that smog reduces people's visibility.
This prevented people from fleeing the fire quickly.
Increased the possibility of poisoning and burns.
three
) the horror of smoke. In the event of a fire, especially after a collision, flames and smoke rush out of doors and windows, and smoke billows.
Get out, the fire is burning,
People have a sense of terror, which often leads to confusion in the evacuation process and makes some people lose their way.
To the normal activity ability, some even lose their heads and panic.
How to use wet towels to prevent smoking
1
) The number of folding layers depends on the texture of the towel.
It is generally appropriate to fold 8 layers of towels.
Therefore, the smoke concentration elimination rate can reach 60%.
2
The towel doesn't need to be wet.
three
Cover your nose and mouth when using, and increase the area of smoke as much as possible.
How to call for help when people are trapped indoors in a fire?
When a fire breaks out, the situation is complicated, people are trapped indoors, sometimes they don't know the surrounding fire situation and can't leave the fire for a while. pass by
Because the fire is fierce, the doors and windows are sealed, and the smoke is easily lost. People were trapped in the building by the fire, calling for help outside, outside
It's hard for people in front to hear. Because the raging fire has formed a wall of fire, it is actually very difficult to call for help.
People trapped at this time should keep calm,
People should lie on the ground and call for help.
When the fire rises along the airflow,
At the bottom
Location,
Combustible substances have been burned or there are unburned places,
Sound waves for help can spread through these gaps.
So the outside world
It is easy to hear the cry for help and try to rescue in time.
How to choose a shelter, we should pay attention to the following points
1
Choose a place facing the street, because it is convenient to observe the fire, and you can get in touch with rescuers through shouting and gestures.
Getting help in time is of great benefit.
2
) Choose a place with a balcony.
three
) Choose a room that is easily accessible from the stairwell.
What if the computer is on fire?
If the computer is on fire,
Even if the machine is turned off,
Even if the plug is unplugged, the components in the machine are still hot.
Will still burn and produce
Poisonous gas, fluorescent screen and kinescope may also explode, and the treatment methods are as follows:
When the computer starts to smoke or catch fire,
Unplug the power plug or turn off the main power switch immediately.
Then cover it with a wet blanket or quilt.
Computers can not only prevent the spread of fireworks, but also block the glass fragments on the screen.
Don't spill water on the burning computer.
This is true even for computers that have been turned off.
Because of the sudden drop in temperature,
It'll make it hot
The picture tube exploded. In addition, there is still residual current in the computer, and splashing water may get an electric shock.
Don't open the lid to watch. When putting out the fire, you can only approach the computer from the side or back to prevent the explosion of the kinescope from hurting people.
How to pay attention to fire prevention when using power socket?
There is a multipurpose triple socket and a quadruple socket in the power socket.
Easy to use, quite popular with students.
However, when using this multi-purpose socket, we should pay attention to the bearing capacity of the power socket and not overload it to ensure safety.
The power socket is marked with rated voltage and current.
This shows the maximum voltage and current that the power socket can withstand.
The product of voltage and current is electric power,
The unit is wattage.
If multiple power outlets are used,
Plug in several appliances, and you should
Carefully calculate whether the power of the inserted electrical appliance exceeds the rated power allowed by the multi-connection socket,
If compared with the rated power of the socket
Low, safe to use. On the contrary, the total power of the electrical appliances used is greater than the rated power of the multi-connection socket, which is unsafe. Because of electricity
When a fluid flows through a metal conductor,
Metal conductors will generate heat, which is called current thermal effect. When the current passes through the conductor, the greater the current,
The more thermal effects.
The higher, the greater the calorific value. When the current of various electrical appliances passes through many.
Anti-electricity measures
1.
Don't plug in or connect the power without permission, especially don't plug in the power with wet hands.
All metal products are conductive. Do not use these tools to directly touch the power supply.
2.
Don't wipe the electric appliance with a wet towel to prevent water from falling into the shell and causing short circuit, so as to avoid electric shock.
3.
In thunderstorm weather, don't stand under the tree to avoid rain, so as not to be struck by lightning.
4.
On the way to and from school, pay special attention to whether the wires on the roadside have fallen off, and you must avoid them when you see them.
5. Check whether the electrical appliances are cut off before leaving home or going to bed.
6, don't connect wires, distribution lines to wear metal pipe protection, don't abuse copper wire.
Wires replace fuses.
7. Don't bake clothes on the electric heater. Keep the electric heater at a safe distance from combustible materials.
Dormitory anti-theft
If the dormitory is not prepared for theft, it will not only cause property losses,
It will even turn into robbery and even endanger life.
Therefore,
Do a good job in dormitory

Room. When going out, all locking bolts should be used to increase the "anti-theft" of the security door.
5. Pay attention to the safety net. Regularly check whether the solder joints are firm and firm to prevent shearing or widening from entering the room.
6, prevent climbing down the pipe burglary. The windows near the downpipe should be strictly inspected and not neglected to prevent theft.
The case happened.
7. When family members go out for a short time at night, it is best to turn on a light or turn on the radio at home.
Or dry some clothes and turn on the lights on the balcony. It is difficult for criminals to judge whether there is anyone at home, so they dare not rashly start.
8. If a criminal is committing a crime, don't panic and treat it calmly.
Measure the strength of both sides and the surrounding environment before acting.
