The function and significance of fire extinguishers

Question 1: Why is it important to have a fire extinguisher? The more comprehensive the explanation, the better. If an enterprise cannot ensure safe production, how can it talk about healthy development? Enterprises must conscientiously implement the work policy of "safety production, focusing on implementation" and do a good job in fire safety work. Earnestly fulfill the fire safety responsibilities stipulated in fire protection laws and regulations, do a good job in fire safety prevention, and create a good fire safety environment for the sustainable, healthy and rapid development of the enterprise.

We work together from the following aspects to ensure that fire safety work is in place step by step.

First, strengthen fire safety knowledge education and improve everyone’s understanding of fire safety. We must attach great importance to fire-fighting work ideologically, put fire-fighting work in the first place of enterprise safety production, and take "hidden dangers are more dangerous than open fires, prevention is better than disaster relief, and responsibility is heavier than Mount Tai" as the motto of doing a good job in enterprise fire-fighting safety work. Keep in mind that fire prevention is the primary task to ensure the safety of enterprises. We must constantly improve employees' awareness of the dangers of fire and the importance of fire prevention, strengthen fire safety education, and be prepared for danger in times of peace, take precautions, and take preventive measures before they occur, especially in terms of ideology. To take the initiative, we must always keep a clear head, firmly establish the idea of ????safety first, and do a good job in fire safety from a political perspective with a highly responsible attitude towards the employees of the company.

Secondly, we should continue to improve the enterprise's fire protection system, assign fire safety responsibilities to specific personnel, and eliminate hidden dangers. Only by continuously carrying out the investigation and rectification of fire hazards can we do a good job in fire protection and strive to prevent the "new amount" of hidden dangers from increasing and gradually reduce the "existing ones". It is necessary to establish a long-term mechanism to prevent and eliminate fire hazards, establish and improve the responsibility mechanism for reporting, supervising and rectifying fire hazards, establish and improve the system for filing and closing cases of major fire hazards, strictly implement the reward and punishment system, and punish those who fail to perform their duties or work ineffectively resulting in serious accidents. In the case of extremely serious fire accidents, responsibility must be strictly investigated in accordance with laws and disciplines. It is necessary to insist on regular inspections of key fire prevention units of the enterprise - oil depots, warehouses where flammable and explosive dangerous goods are stored, etc., identify problems, and make rectifications in a timely manner. At the same time, fire-fighting equipment must be equipped and fire prevention measures must be implemented. It is necessary to formulate strict fire prevention rules and regulations according to the differences of each key fire prevention unit, and designate a special fire prevention person in charge to truly implement the measures and assign responsibilities to the people.

Once again, the person in charge of the enterprise should strengthen the management of fire-fighting equipment and equipment. Fire-fighting facilities and equipment are important equipment and facilities for fire prevention and fire-fighting. All fire-fighting equipment and equipment of the enterprise must be inspected and repaired regularly in accordance with the provisions of the national fire protection technical specifications to ensure that the fire-fighting facilities and equipment are intact and effective. For units with automatic alarm systems, the detectors should be cleaned every three years and necessary threshold tests should be carried out. Maintenance contracts should also be signed with enterprises with maintenance qualifications. In addition to regular maintenance, the maintenance enterprises should In addition, system function inspection and testing should be carried out at least once a year to ensure its normal use. It is also necessary to intensify on-duty inspections and establish inspection records. When inspecting and protecting the factory, the security personnel of the enterprise should be more vigilant and put fire prevention work first. During the inspection, they should carefully check the key fire prevention parts, discover fire hazards, and take timely measures to nip the fire hazards in the bud.

Finally, enterprises should organize voluntary fire brigade and strengthen their training. It is necessary to strengthen fire-fighting education for enterprise cadres and employees, regularly organize team members to learn and publicize fire protection regulations, fire prevention and fire-fighting knowledge, and skills, formulate fire-fighting plans for key locations, and organize fire-fighting drills regularly so that problems can be discovered in a timely manner and plans can be improved. At the same time, voluntary Firefighters must be able to publicize fire protection knowledge and report fire alarms, use fire extinguishing equipment, discover and eliminate general fire hazards, and put out initial fires, so as to more effectively protect the safety of people's lives and property.

Only by checking at all levels from thought to technology can fire hazards be truly minimized. Therefore, enterprises must be guided by the promotion of fire safety knowledge, thereby improving employees’ understanding of fire protection and increasing training efforts. Respond to sudden fire hazards.

Question 2: What is the purpose of a fire extinguisher? Use fire extinguishing equipment correctly; water is the most commonly used extinguishing agent, easy to access and rich in resources, but it should be noted that water cannot be used to extinguish fires in live equipment; the purposes and methods of use of various fire extinguishers are as follows:

Acid-base fire extinguisher: Turn it upside down and shake it slightly or turn on the switch, and the agent will spray out; suitable for extinguishing oil fires.

Foam fire extinguisher: Turn the fire extinguisher barrel upside down; it is suitable for extinguishing wood, cotton, paper and other fires, but cannot extinguish electrical and oil fires.

Carbon dioxide fire extinguisher: Hold the horn with one hand and point it at the fire source, and turn on the switch with the other hand; it is suitable for extinguishing valuable instruments and equipment, but cannot extinguish fires caused by metal potassium, sodium, magnesium, aluminum and other substances.

Haloalkane fire extinguisher (1211): First unplug the push pin, then hold the pressure switch, and the pressure rod opens the sealing valve, and the agent is ejected from the nozzle under ammonia pressure; suitable for extinguishing flammable liquids , flammable gas and electrical equipment and other fires. (Note: 1211 fire extinguisher will cease to be used on January 1, 2005)

Dry powder fire extinguisher: Open the safety pin, aim the nozzle mouth at the fire source, pull out the pull ring, and it will spray out; applicable Suitable for fighting fires involving petroleum products, paints, organic solvents and electrical equipment.

Question 3: The Importance of Fire Extinguishers If an enterprise cannot ensure safe production, how can it talk about healthy development? Enterprises must conscientiously implement the work policy of "safety production, focusing on implementation" and do a good job in fire safety work. Earnestly fulfill the fire safety responsibilities stipulated in fire protection laws and regulations, do a good job in fire safety prevention, and create a good fire safety environment for the sustainable, healthy and rapid development of the enterprise.

Question 4: The meaning of the fire extinguisher label. The so-called ABC refers to the raw materials of dry powder fire extinguishing agents.

There are two main types of dry powder fire extinguishing agents, divided into BC and ABC.

The raw material of BC is baking soda, sodium bicarbonate

The raw material of ABC is monoammonium phosphate, Mono Ammonium Phosphate

In terms of fire extinguishing effect, ABC is better than BC, but BC fire extinguisher The price is cheap.

Carbon dioxide fire extinguishers: MT3, MT5, MT7, these are basically the differences in capacity

Question 5: Who knows the meaning and function of fire management? In recent years, the continuous development of society and economy, the continuous expansion of urban construction scale, the continuous increase of high-rise buildings and public entertainment venues, and the continuous emergence of new fire hazards have brought new challenges to fire protection work. Eliminating fire hazards and strengthening supervision Law enforcement is particularly important, and the shortage of active fire police and the increase in fire hazards have made conflicts in all aspects increasingly prominent. In order to solve these problems and contradictions, Changzhou Municipal People's Government recruits ambitious young people from local areas who are enterprising, hard-working and passionate about firefighting work as firefighting coordinators. The employment of fire coordinators enriches the power of fire supervision and further relieves the pressure on public security fire officers. Based on the work experience of the past two years, the author discusses the role of firefighting coordinators with brother units.

1. Publicity that highlights the social aspect

At this stage, people’s knowledge of fire protection has been greatly improved compared to before, but overall it is still lacking. This is It is necessary to increase firefighting publicity and education, popularize firefighting knowledge and improve firefighting skills, so as to minimize casualties and property losses. So as a fire coordinator, how to further carry out fire protection publicity at the social level is particularly important.

(1) Communicate more with relevant leaders and give full play to the collective strength of the police station

Carrying out fire protection publicity work is not a matter of one person. It can only be achieved by everyone’s efforts. Now most fire fighters Coordinators are dispatched to grassroots police stations to assist in their work, which cannot be separated from the support of police station leaders and civilian police. Actively report to the leaders of the police station, especially the leader in charge of fire protection work, the progress of fire protection work, actively grasp the spirit of relevant document meetings of the superior public security fire department, and form unique opinions, communicate with the leaders of the police station in a timely manner, and further promote the fire protection work of the police station. develop in a healthy and orderly direction.

(2) Pay attention to the relevant spirit in daily life and accumulate experience.

To carry out fire protection publicity work, we must pay more attention to it and accumulate more experience. Take the new fire protection legal document format and fire protection administrative penalty discretion standards introduced in 2008. These two aspects can be said to be a completely new format and spirit than before. If you want to update your fire management knowledge in a timely manner and understand the new fire management spirit, you must pay more attention to the fire protection website and browse more to receive new emails and new regulations.

In daily work, we must also accumulate knowledge and further summarize experience. For example, when it comes to the selection of fire extinguishers, many places or self-employed people now think that as long as they have it, it will be enough, without looking at the model or validity period of the fire extinguisher. As a firefighting coordinator, you should have a clearer understanding of what type of fire extinguisher should be used in which place. Only in this way can fire protection publicity achieve the desired goal.

(3) Pay attention to form and create a good fire protection publicity atmosphere

The popularization of fire protection knowledge in society and the improvement of fire-fighting skills are inseparable from fire protection publicity. As a fire protection coordinator Members should focus on the following aspects. First, long-term and timely notification of fire conditions and statistical data. Today's news information is quite developed. News media will quickly report on large and small fires that occur in various places, especially malignant fires that cause mass deaths and injuries. News media in various places have more in-depth and detailed reports and analysis. These news, especially fires that occur in the same type of enterprises, enterprises should collect information in a timely manner and regularly inform employees. This will serve as a warning to employees' fire safety concepts and help prevent similar accidents from happening in the enterprise. The second is fire slogan promotion. Fire slogans can be fixed. Fire slogans can be written on the wall to serve as a long-term warning. They can also be hung in the form of red banners on the road, outside the exterior walls of buildings, at the entrance to wet markets, etc., aiming at the needs of this period. Warning about fire characteristics. The third is to visit the fire station. In October 2000, the Fire Bureau of the Ministry of Public Security decided to promote regular opening of fire stations across the country so that corporate employees...>>

Question 6: The role of fire extinguishers. The composition of dry powder fire extinguishers is 50% It is made of ammonium phosphate + 25% ammonium sulfate dry powder and filled with nitrogen. It does not contain smoke bombs, sulfur, gunpowder and other substances. Therefore, even if it is dropped from a high building, it will only cause the leakage of dry powder and nitrogen in the fire extinguisher and cannot be used as a bomb. and the use of smoke bombs

Question 7: Briefly discuss your understanding of the importance of fire safety. Fire and water have no mercy, which talks about the importance of fire safety. Fire safety is a top priority for every company, and our villa is no exception. The hotel is a public place, with a large number of people coming in and out every day. While receiving every guest, it must also prevent vandalism, smoke and throw cigarette butts everywhere, and smoke while lying on the bed after drinking... Many safety hazards cannot be ignored. To this end, the resort invested a lot of money last year to update fire alarm systems, fire extinguishers and other fire-fighting equipment, and set up safety evacuation plans behind the doors of each guest room. At the same time, new employees are trained so that each employee can master fire protection knowledge and operational points, constantly grasp the ideological awareness, strengthen fire protection responsibilities, identify problems, report them in time, and solve them in time. All employees of the Safety Department have received multiple trainings, conducted on-site drills on automatic alarm handling methods, and learned basic fire extinguishing methods, fire escape and evacuation, etc., striving to achieve a solid foundation. The focus of firefighting work is mainly on prevention and combining prevention and firefighting. Only by making preparations in advance can you avoid chaos when things happen. As the saying goes, "If you don't panic before battle, the disaster will be halved." In terms of fire alarm system handling methods, first of all, keep a cool head and stay calm. Find out the location, number, and distribution of the fire alarm through the location instructions of the fire alarm system; find out the alarm point and the cause of the fire detector alarm as soon as possible, and find out the cause of the fire alarm. Whether it is a fire or a false alarm, fire control personnel must rush to the scene quickly to check; secondly, if it is confirmed that a fire has occurred, it can generally be divided into two handling methods: First, if the fire is small, a fire extinguisher can be used to put out the fire. Second, if the fire is large, employees of the unit must be organized in time, use existing fire-fighting facilities, put out the fire, evacuate guests, and quickly dial 119 to notify the fire department. Finally, if it is found that the alarm system caused a false alarm, the minor fault should be eliminated immediately. If the fault is larger and cannot be eliminated, it should be reported to the leader immediately, and a dedicated person should be notified to repair it in time, and records should be kept afterwards. Fire and water are merciless. We must remember fire safety above all else!

Although we cannot live without fire. However, if used improperly or the fire is not managed properly, fires can easily occur. Fires seriously threaten people's lives and cause huge losses to the safety of our lives and property and the construction and development of the country! Fire safety is very important. In our lives, we should always pay attention to fire safety and use fire with caution. Only in this way can we build a beautiful home together.

Now let me talk about some fire protection knowledge!

2. The circuit of air conditioning equipment should be a separate circuit, and the socket should be a flame-retardant socket;

Silly , electrical circuits should be checked frequently to prevent aging, short circuit, leakage, etc.;

4. Do not use other wires to replace fuses;

Question 8: What do the letters on the fire extinguisher mean? Hello!

The ABCDE on the fire extinguisher refers to the type of fire that the fire extinguisher can extinguish.

National standards divide fires into six categories based on burning objects

Class A fires: solid material fires. This substance is usually organic in nature and typically produces glowing embers when burned.

Class B fire: Fire involving liquid or meltable solid material.

Class C fire: gas fire.

Class D fire: Metal fire.

Class E fire: Live fire. A fire in which an electrified object burns.

Class F fire: Fire caused by cooking materials (such as animal and vegetable fats) in cooking utensils.

If you have any questions, please ask.

Question 9: What do the letters on the fire extinguisher mean? They represent the type of fire extinguisher and its ingredients.

There are many types of firearms, which are suitable for extinguishing different types of initial fires. The methods of use are also different. Common ones are:

1. Portable foam fire extinguishers Foam fire extinguishers are suitable for extinguishing fires Initial fires involving oils and general substances. When using, hold the lifting ring of the fire extinguisher with your hands and lift it to the fire scene smoothly and quickly. Do not carry it sideways or hold it sideways. When extinguishing a fire, hold the lifting ring with one hand and the bottom edge of the barrel with the other hand. Turn the fire extinguisher upside down, aim the nozzle at the fire source, and shake it vigorously a few times to extinguish the fire. Note: 1. Do not point the cover and bottom of the fire extinguisher towards the human body to prevent the cover and bottom from popping up and injuring people. 2. Do not spray it together with water at the same time to avoid affecting the fire extinguishing effect. 3. When putting out an electrical fire, try to cut off the power first to prevent people from getting electric shock.

2. Portable carbon dioxide (CO?) fire extinguisher Carbon dioxide fire extinguisher is suitable for extinguishing initial fires in precision instruments, electronic equipment and electrical appliances below 600 volts. There are two ways to use portable carbon dioxide fire extinguishers, namely handwheel type and duckbill type. Hand wheel type: Hold the handle of the spray gun with one hand, tear off the lead seal with the other hand, rotate the hand wheel counterclockwise, turn on the switch, and the carbon dioxide gas will be ejected. Duckbill type: Hold the handle of the spray gun with one hand, pull out the safety pin with the other hand, and press the duckbill on the handle to put out the fire. Note: 1. When putting out a fire, personnel should stand upwind. 2. The hand holding the spray tube should be held at the glue nozzle to prevent frostbite. 3. After indoor use, ventilation should be strengthened.

3. Portable dry powder fire extinguishers Dry powder fire extinguishers are suitable for extinguishing initial fires involving oil, combustible gas, and electrical equipment. When using it, first open the safety pin, hold the nozzle with one hand, aim it at the fire source, and pull the pull ring with the other hand to extinguish the fire source.

4. Portable "1211" fire extinguisher "1211" fire extinguisher is suitable for extinguishing initial fires of valuable items such as oil, instruments, cultural relics and files. When using it, first tear off the aluminum seal, pull out the safety pin, hold the bottom of the fire extinguisher with one hand, hold the pressure handle switch with the other hand, aim the nozzle at the fire source and spray, release the pressure handle, and the spray will stop.

5. Small household fire extinguishers Household fire extinguishers are suitable for extinguishing small fires in kitchens, living rooms, and bedrooms. There are two types: spray type and throwing type. When in use: Spray type - press the spring button on the top of the fire extinguisher, aim the nozzle at the fire, and spray the fire to extinguish it. Throwing type - just throw it into the fire, the container will break, and the dry powder will be released to extinguish the fire.

CO? Maybe it’s the letter you’re talking about.

Question 10: What fire extinguishing principle is used by dry powder fire extinguisher? The main ingredients of dry powder fire extinguishing agent are sodium bicarbonate and a small amount of moisture-proof agent magnesium stearate and talc powder. Use dry carbon dioxide or nitrogen as power to eject the powder from the container to form a powder mist and spray it into the combustion zone. The sodium bicarbonate in the dry powder is decomposed by high temperature. The chemical reaction equation is as follows: 2NaHC03 → Na2C03 + H20 + C02

This reaction is an endothermic reaction. The reaction releases a large amount of carbon dioxide and water. The water is heated into water vapor and absorbs a large amount of heat energy, which plays a certain role in cooling and diluting combustible gases.

There are many types of dry powder fire extinguishing agents, which can be roughly divided into three categories:

Dry powder based on sodium bicarbonate (potassium) is used to extinguish flammable liquids, gases and Fires in live equipment;

Dry powders based on triammonium phosphate, diammonium hydrogen phosphate, ammonium dihydrogen phosphate and their mixtures are used to extinguish combustible solids, flammable liquids, combustible gases and electrical equipment. Fire;

Thousand powders based on sodium chloride, potassium chloride, barium chloride, sodium carbonate, etc. are used to extinguish light metal fires.

There are three methods for extinguishing fires: suffocation, cooling, and isolation. Dry powder fire extinguishers use the suffocation method. The sprayed dry powder covers the flame and isolates it from the air. The fire extinguisher only uses To extinguish the initial fire.
