Fire safety英语作文~

The campus is personnel public gathering places, the height of teaching instruments and equipment, scientific research value of electricity, experiment, practice project and combustible, once the fire accident, great influence, and great losses, directly affects the normal teaching and research work. Therefore, our attention for many years, always put fire control work on campus work on fire prevention work first. Fire prevention campus is a grasping tireless work, students learn knowledge of fire is indispensable in the lesson.
In order to enhance the students' awareness of fire safety, fire safety responsibility for students to learn, fire safety knowledge, we edit the "fire safety knowledge. This book mainly include: the fire extinguisher basic knowledge, basic knowledge, early fire fighting fire evacuation method, and the fire escape knowledge, knowledge interlocution, etc, and collect the campus fire case, fire safety knowledge competition, etc. Its purpose is to let students understand this book, learning through fire safety knowledge, be familiar with the performance characteristics of fire extinguishing, master, evacuation, escape skills, improve the defense self-rescue ability, prevent campus fire. At the same time, also for the vast number of students and students learn and obligatory fire brigade provides information. We hope that, through the study on fire control safety knowledge, make the students do SanDong "three", namely: understand the harmfulness of fire, fire fighting, and understand the fire prevention methods of measures: will quote fire extinguisher, can use, can escape.
"Hidden risks in fire prevention is better than relief, responsibility, than mount tai. We hope our students consciously assume the responsibility and fire control work on campus, more learning and obligation, and observe the master knowledge of fire fire system, actively participate in campus, make our fire control work "all care about fire, fire" of attention to materialize, radically reduce or avoid campus fire accident.

(1) the definition of combustion
Fire, burning, commonly known as the oxidant refers to the role of combustibles away from fire, usually accompanied by exothermic reaction, shine and (or) of smoke.
With three characteristics, namely the burning heat and chemical reaction, shine.
(2) burning conditions
The necessary conditions for the burning of the combustion process - substance and development, must have the following three necessary conditions, namely: combustible, antioxidant and temperature (fire) lead. Only these three conditions occur, and burning phenomenon, no matter what a condition, lack of combustion can occur. But, not the above three conditions exist at the same time, it must happen burning phenomenon, must also be these three factors interact to combustion.
1 who can combustible: with the oxygen in air or other antioxidants on combustion chemistry substance called burnable. According to its physical state into the combustible gas, liquid and solid combustible combustible combustible three categories. Can burn material is mostly hydrogen and carbon compounds, some metals such as aluminum, magnesium and calcium in certain conditions can burn, and many substances such as hydrazine ozone at high temperatures can decompose and released by his light and heat.
2: help and support antioxidant combustible substances, which can burn with combustible substances called oxidation reaction. The combustion process is mainly in the air oxidants such as oxygen free of fluorine, chlorine, such as the reaction can burn.
3 temperature (led) : refers to the source and oxygen supply of fuel combustion burner or reaction energy sources. Common heat energy, there are other, electricity, heat energy transformation, etc.
4 the chain reaction: there exists flame combustion chain reaction. When some burnable heated, it will not only, and the fuel vaporization of molecular occur warm solutions are produced by the action of free radicals. Free radicals are a highly active chemical form, and other radicals and molecular reactions, and make the combustion, it is the ongoing burning chain reactions.
The sufficient conditions for burning, (1) the burnable concentration; certainly (2) some content of oxygen (3) certain ignition energy. (4) by inhibiting the chain reaction. Example: the minimum ignition energy petrol raj 0.2 to 19mJ o., ether, 0.215 methanol as mJ. For before the flame combustion, three conditions exist, interaction, and burn that will happen. But for the flame combustion %

People are alarmed by the succession of campus fires in recent years.In each of these accidents, heavy casualties were reported – houses were burned down, students lost their lives, and properties were damaged.Faced with such a chilling fact, people keep asking, “What on earth results in these repeated tragedies? ”

A brief survey of them reveals that human factors still prove to be the leading causes.For example, three of these fires were caused by the students’ use of electric water-heaters.As students often leave the heaters unattended, the risks are rather high should the water in the bottle boil dry while no one is around to turn off the power.In other cases, fires were also caused by stoves, candles, cigarette butts, etc.

Since most of these disasters could have been prevented if proper precautions had been taken, students should be better educated on the importance and measures of fire control.The following three reminders are of particular importance for us students: First, learn how to use a fire extinguisher.Second, double-check candles, heaters, stoves and other electric appliances, and make sure there are no open flames before leaving rooms.Lastly, do not smoke in the dorm.

In recent years there has been a marked growth of fire accidents in big cities of our country.Almost every day we see fire engines rushing through the streets.Fires have not only resulted in heavy economic losses but also injured and killed many people.What are the causes of fire accidents?Most of the fires are brought about by carelessness and violation of fire safety regulations.Others are due to the poor quality of home electrical appliances.By the way,some people don't know how to use them properly.Besides,there are quite a few businesses which focus so much of their attention on profits that they tend to neglect and even ignore fire precautions.In my opinion,in order to prevent fires we should first of all foster people's sense of fire prevention.The second thing we have to do is to increase the number of professional fire fighters,to whom regular training courses should be offered.Finally,we are to improve the existing fire engines and add more fire facilities to high-rise buildings.In this way,a reliable fire prevention system will be formed.

When did people start to use fire?No one knows,but we know it was a long time ago.Some people say it was about 200,000 years ago.Other people say it was 1,000,000 years ago.Fire was useful then and fire is useful now.Fire was a great thing.It changed our future but fire can aslo be very dangerous.Don't play with fire and when you see a fire.You should be carful.

If you find the fire at home, please run away. Don't use the elevator! It's dangerous! Stop thinking about anything else! Climb out of the house with your head down and call 110 and ask the fireman to help you!
