In order to ensure the personal safety of employees and the property safety of the company, it also sounded the alarm for our safe production. The company has been adhering to the principle of "everyone is responsible for safety in production" to improve everyone's safety awareness, and has conducted special fire safety training for employees:

Causes and development trend of fire

Fire is one of the most frequent disasters in the world. All countries try their best to find preventive measures from the causes of fires. On the basis of summing up the experience and lessons of fire control work, the public security fire control institutions in China study the law of fire occurrence and take targeted preventive measures to ensure the safety of state property and people's lives.

I. Fire

Fires have different classification methods according to their nature, burning characteristics of substances, causes of fire, losses and places of occurrence.

The national fire protection standard (GB4986-85) classifies fires into four categories according to the combustion characteristics of substances:

(1) Class A fire. Refers to the fire of solid matter. This kind of substance often has the nature of organic matter, and generally produces glowing embers when burning. Such as wood, cotton, wool, hemp, paper fire, etc.

(2) Class B fire. Refers to liquid fire and solid material fire that melts when heated. Such as gasoline, kerosene, diesel oil, crude oil, methanol, ethanol, leaching, paraffin burning, etc.

(3) Class C fire. Refers to a gas fire. Such as gas, natural gas, methane, ethane, propane, hydrogen fire, etc.

(4) Class D fire. Of metal fire. Such as potassium, sodium, magnesium, titanium, lithium, aluminum and other metal fires.

Second, the classification of fire losses

Article 6 of the Regulations on the Management of Fire Statistics (Guo Tong Zi [1996] No.82) issued by the Ministry of Public Security, the Ministry of Labor and the National Bureau of Statistics stipulates that fires can be divided into three categories according to casualties, affected households and direct property losses caused by fire accidents:

(a) more than ten people died (including the number, the same below); Seriously injured more than 20 people; More than 20 people were killed or seriously injured; More than 50 families were affected; The direct property loss is more than one million yuan.

(2) A fire with one of the following circumstances is a major fire: more than three people are killed at one time; Seriously injured more than ten people; More than ten people were killed or seriously injured; More than 30 families were affected; The direct property loss is more than 300,000 yuan.

(3) A fire that does not meet the first two conditions is a general fire.

Third, the cause of the fire

Fire fighting is a long-term and complicated work, and it is a great achievement for the benefit of the country and the people. Therefore, the state has formulated a series of fire laws, regulations, standards and technical specifications to guide people to prevent fires and ensure the safety of state property and people's lives and property.

The occurrence of fire has its inherent law and specific causal relationship, but it is inseparable from social environment, economic prosperity, wealth accumulation, human negligence and potential factors. Know, know, can suit the remedy to the case, effectively prevent the occurrence of fire.

(A) fires caused by human factors in production and life

Fire statistics show that there are many direct causes of fires over the years, but no matter which one, it is almost related to people's ideological paralysis.

1, careless use of open flame.

There are many kinds of fires caused by careless use of open flames, and the most common ones are as follows:

(1) Fire caused by cooking;

(2) Fire caused by littering cigarette butts and matchsticks;

(3) Fire caused by careless gas welding and electric welding;

(4) Fires caused by barbecue items and cooking items;

(5) Fire caused by fire heating.

2. Fire caused by improper installation and use of electrical appliances.

With the continuous improvement of people's living standards, more and more electrical appliances have entered the homes of ordinary people, and a slight carelessness may cause a fire. Common electrical fires mainly include the following:

(1) The motor is overloaded or has poor insulation, resulting in short circuit and fire;

(2) The electrical wiring is not installed firmly or the connector is loose, causing the surrounding combustible materials to catch fire;

(3) The wires are randomly connected or the insulation layer of the lines is aged or damaged, resulting in short circuit of parallel lines and spark ignition;

(4) transformer coil insulation damage or poor connector contact causes short circuit or excessive resistance to heat and catch fire;

(5) Used electric irons, soldering irons and electric stoves. It caught fire without cutting off the power supply;

(6) The fuse (fuse) is unqualified in installation and use, loses its protection function when overloaded, or causes a fire by replacing the fuse with other wires;

(7) Use high-power light bulbs to catch fire near flammable materials.

3, in violation of operating procedures when hot.

In terms of human factors, more than 70% of fires in enterprises and institutions are caused by violation of operating procedures. The main reasons are as follows:

(1) mixing dangerous chemicals with conflicting properties, causing fire;

(two) illegal welding operations, causing fire;

(3) In the process of chemical production, over-temperature and over-pressure operations cause fires;

(4) AWOL in production causes fire;

(5) Smoking or using fire in places where inflammable and explosive chemicals are heard, causing fire;

(6) When handling inflammable and explosive articles, fire may be caused by random tumbling, collision and friction.

Four, the types and methods of use of fire extinguishers:

1, dry powder fire extinguisher, suitable for fighting fires of petroleum products, paints and organic solvents, but unable to fight fires burning light metals.

Before use, turn the fire extinguisher up and down several times about 5 meters away from the windward direction of the ignition point to loosen the dry powder in the cylinder. Pull out the safety pin first, press the handle with one hand, hold the nozzle with the other hand at a 45-degree angle, aim at the root of the fire source from near to far, and shoot from left to right until the fire source is completely extinguished.

2, nitrogen dioxide fire extinguisher, suitable for putting out fires in expensive instruments and equipment, archives, computer rooms, it is not conductive, it is also suitable for putting out live low-voltage electrical equipment and oil fires, but it can't be used to put out fires of potassium, sodium, magnesium, aluminum and other substances. The use method is similar to that of dry powder fire extinguisher.

3. 12 1 1 fire extinguisher, especially suitable for putting out fires of precision instruments, electronic equipment and cultural relics.

4. foam extinguisher is the most suitable place to put out liquid fires, but it can't put out water-soluble flammable flammable liquids (such as alcohol, ester, ether, ketone and other substances) and electrical appliances.

Five, the basic method of fire fighting

1. cooling fire extinguishing (water and carbon dioxide fire extinguishing agent);

2. Isolation fire extinguishing method (separation of combustibles from unburned materials);

3. Asphyxiation fire extinguishing method (using asbestos cloth, soaked quilt, canvas, sand and other incombustible or flame retardant materials);

4. Chemical suppression fire extinguishing method (dry powder fire extinguishing agent)

Six, fire safety knowledge

1. Electrical fire is caused by improper design, installation, maintenance and use of electrical equipment. Specific manifestations are: electrical short circuit, equipment overload, poor contact of wire connection points, aging and deterioration of electrical insulation materials, etc.

2. Line overload means that the actual load current flowing through the conductor exceeds the maximum safe current value specified by the conductor section. Circuit overload makes the temperature of conductor exceed its maximum allowable working temperature, and the insulation layer of conductor will accelerate aging, even deteriorate and damage, causing short circuit and fire.

3. Fire is generally divided into four stages: initial fire, intermediate fire, vigorous fire and declining fire.

4. The thermal radiation temperature generated by fire can reach 400-500℃.

5. The best extinguishing time is 0-3 minutes, and the best escape time is 3- 10 minutes.

6. The correct position for the car to break the burning glass is in the middle.

7. During the fire alarm, the focus of the first report is: fire location, fire substances, and whether anyone is trapped.

Seven, alarm mode

If property employees find the fire alarm channel: 1, call 587 17523 (central control room); 2. Report to the competent leader; 3, manual alarm button alarm; Assist in evacuation.
